As used herein, the term “gene” refers to a DNA sequence that includes control and coding sequences necessary for the production of an RNA, which may have a non-coding function (e. g., a ribosomal or transfer RNA) or which may include a polypeptide or a ptide precursor. The RNA or polypeptide may be encoded by a full length coding sequence or by any portion of the coding sequence so long as the desired activity or function is retained. The term “gene” also refers and encompasses the respective alleles of the plant cultivar or plant line.

An allele is one of several alternative forms of a gene or nucleotide sequence at a specific variation at a given position within the nucleic acid sample. An allele may be represented by one or more base changes at a given locus (e. g., a 8NP). For example, at each autosomal locus a diploid dual possesses 2 alleles, one maternally inherited, the other paternally. [005 9] As used herein, the term “pathogen” refers to an infectious agent that causes disease in its host. In n embodiments, a pathogen is Phytophthora ans.

As used , the term “coding sequence” refers to a sequence of a c acid or its complement, or a part thereof, that can be transcribed and/or translated to produce the mRNA for and/or the polypeptide or a fragment thereof. Coding sequences include exons in a genomic DNA or immature primary RNA transcripts, which are joined together by the cell’s biochemical machinery to provide a mature mRNA. The anti-sense strand is the complement of such a nucleic acid, and the encoding sequence can be deduced therefrom.

As used herein, the term “non-coding sequence” refers to a sequence of a nucleic acid or its complement, or a part thereof, that is not transcribed into amino acid in vivo, or where tRNA does not interact to place or attempt to place an amino acid. Non- coding sequences include both intron ces in genomic DNA or immature primary RNA transcripts, and gene-associated sequences such as promoters, enhancers, silencers, etc.

A nucleobase is a base, which in certain preferred embodiments is a purine, dine, or a derivative or analog thereof. Nucleosides are nucleobases that contain a pentosefuranosyl moiety, e. g., an ally substituted de or 2’-deoxyriboside.

Nucleosides can be linked by one of l linkage moieties, which may or may not contain phosphorus. Nucleosides that are linked by unsubstituted odiester linkages are termed nucleotides. The term “nucleobase” as used herein includes peptide nucleobases, the subunits of peptide nucleic acids, and morpholine nucleobases as well as nucleosides and nucleotides.

An oligonucleobase is a r sing nucleobases; preferably at least a portion of which can hybridize by Watson-Crick base pairing to a DNA having the complementary sequence. An oligonucleobase chain may have a single 5’ and 3’ terminus, which are the ultimate nucleobases of the r. A particular oligonucleobase chain can contain nucleobases of all types. An oligonucleobase compound is a compound comprising one or more oligonucleobase chains that may be complementary and hybridize by Watson-Crick base pairing. Ribo-type bases include pentosefuranosyl containing nucleobases wherein the 2’ carbon is a methylene substituted with a hydroxyl, alkyloxy or halogen. Deoxyribo-type nucleobases are nucleobases other than ribo-type nucleobases and include all bases that do not contain a pentosefuranosyl moiety.

In n embodiments, an oligonucleobase strand may include both oligonucleobase chains and segments or s of oligonucleobase chains. An oligonucleobase strand may have a 3’ end and a 5’ end, and when an oligonucleobase strand is coextensive with a chain, the 3’ and 5’ ends of the strand are also 3’ and 5’ termini of the chain.

As used herein, the term “gene repair oligonucleobase” or “GRON” refers to oligonucleobases, including mixed duplex oligonucleotides, non-nucleotide ning molecules, single stranded oligodeoxynucleotides and other gene repair molecules.

As used herein, the term “isolated” when referring to a nucleic acid (e. g., an oligonucleotide such as RNA, DNA, or a mixed polymer), refers to a nucleic acid that is apart from a substantial portion of the genome in which it naturally occurs and/or is substantially separated from other cellular components which naturally accompany such nucleic acid. For e, any nucleic acid that has been produced synthetically (e. g., by serial base condensation) is considered to be isolated. Likewise, nucleic acids that are recombinantly expressed, cloned, produced by a primer extension reaction (e.g., PCR), or otherwise excised from a genome are also considered to be isolated.

DETAILED DESCRIPTION OF THE INVENTION Allene oxidase synthase proteins Allene oxide se 2 (AOS2) proteins belong to cytochrome P450 superfamily and comprise the CYP74 group specialized in the metabolism of hydroperoxides. These proteins act in the plant in biosynthesis pathway which is important for generating substances that play important roles in a variety of plant stress and developmental processes including pathogen/insect attack as well as plant fertility.

Hughes et al., Chembiochem 10:1122 (2009). These enzymes are coded by three distinct genes AOSl, 2 and 3, which catalyze the respective tion of C6 aldehydes, Jasmonic acid (JA) and C9 aldehydes. AOSl and AOS2 are chloroplast located enzymes while the expression of AOS3 is reported to be confined to below ground organs in potato. Stumpe et al., Plant J 47: 883 (2006). All three are unusual rome P450 proteins, which do not bind molecular oxygen but use already oxygenated fatty acid hydroperoxide ates as the oxygen donor. Schaller and Stintzi, Phytochemistry 70:1532 (2009). AOS2 protein zes the determinate step in Jasmonic acid (JA) formation in plants. Jasmonic acid is well known for its important role in plant defense induction in response to plant wounding and pathogen attack.

Allene Oxidase Synthase 2 (AOS2) alleles and SNPs associated with pathogen resistance and/or tolerance W0 2014/153178 AOS2 gene product is known as Allene Oxide Synthase 2 and catalyzes the conversion of hydroperoxides to allene oxide, the committed step in jasmonic acid (JA) biosynthesis. Jasmonic acid and its derivatives collectively known as jasmonates are key signaling molecules involved in the induction of plant defense reactions in response to pathogen attack or wounding. Loss of JA production or sensitivity to it, results in the enhanced disease susceptibility of plants — e. g., Arabidopsis coil mutants (Feys et al., Plant Cell. 6(5):751-759 (1994)). In potato, JA application inhibits gial germination and mycelial growth of hthora infestans (Pi). The Solanum tuberosum AOS2 (StAOS2) gene is mapped to a quantitative resistance locus (QRL) on the potato chromosome XI that harbors the R3a resistance gene that acts in the race specific e resistance t Pi. Pajerowska et al., Planta 228:293 (2008). In addition, silencing of the A082 gene in potato led to highly reduced levels of jasmonic acid in wounded plants and increased lesion development when infected with Pi.

(Pajerowska-Mukhtar et al., 2008, Planta 228:293 (2008). StAOS2 gene complemented an AOS2 gene knock out line of Arabidopsis thaliana which lacked JA and this complemented plant line, when compared to the gene deleted line, exhibited enhanced ance to a bacterial en of Arabidopsis. (Pajerowska-Mukhtar et al., 2008). ] ces of five AOS2 alleles originating from diploid potato utilized in pre- breeding populations are known. Pajerowska et al., (2008); Pajerowska-Mukhtar et al., Genetics 181:1115 (2009). These five different s are categorized into three groups, “resistant” (StAOS2-1, StAOS2-6), al” (StAOS2-12) and “susceptible” (StAOS2-7, StAOS2-8). In the above mentioned published studies, two populations of F1 ies of heterozygous parent lines were categorized as quantitative resistant, quantitative l and quantitative susceptible according to late blight development. Later, these categories were linked with the specific alleles of StAOS2 gene listed above.

Complementation analyses of the Arabidopsis JA ent mutant with the StAOS2 alleles resulted in restoring JA production (and 12-oxo-phytodienoate (OPDA) reductase, an intermediate in JA biosynthesis). onally, complementation by “resistant” alleles led to a 10-fold increase in JA production compared to the levels produced by the ptible” alleles. The “neutra ” allele had intermediate levels of JA and OPDA.

Additionally, a pathogen assay utilizing Erwim'a carotovora ssp. carotovora on these complemented Arabidopsis lines corroborated the JA production profile by exhibiting 10 W0 2014/153178 times more bacterial growth in plants complemented with the “susceptible” alleles than by the “resistant” alleles.

Comparison of the amino acid sequence of the five different alleles revealed the presence of le amino acid differences along the otherwise highly conserved sequence of the A082 gene alleles. Twenty five amino acid variations and one InDel tion/deletion rphism) are present in the five alleles with five amino acids (N76D, V2898, V292A, M328L and T495K) and the InDel being specific to the “resistant” alleles based on numbering of the susceptible allele StAOS2-7 (SEQ ID NO: ). No amino acid variation was specific to the “susceptible” alleles. Three substitutions (Y145F, T23lI/G and K394T) occurred in the neutral allele. Pajerowska et al., Planta 228:293 (2008).

The amino acid changes T495K and N76D are in close proximity to the active site. F256V polymorphism between StAOS2-1 and StAOS2-6 is ed to explain the slight inferior performance of StAOS2-6 based on its location relative to the substrate binding pocket. In addition, Yl45F of the l allele may contribute towards its intermediary activity profile since this residue is adjacent to the active site wska- Mukhtar et al., Planta 228:293 (2008).

An evaluation of the field resistance of potato cultivars to Pi revealed the A082 gene to be an important locus that s the resistance phenotype of certain cultivars Pajerowska-Mukhtar et al., Genetics 181:1115 (2009). Two SNPs, StAOS2_SNP691(A) and StAOS2_SNP692(C) are ated with field resistance C value of 0.15 which indicates very low disease establishment). In this study, the most resistant genotype to late blight had the homozygous AAAA/CCCC genotype and a positive correlation was observed with the degree of deviation from this and the severity of late blight development. These two SNPs are also reported to be associated with plant maturity (PM). In general, a positive correlation exists between potato maturity rating (early vs. late maturing cultivars) and Pi resistance. Wastie RL, Adv Plant Pathology 7: 193 (1999). However, those individuals gous for the A and C s fall into the mid-early maturity class thus separating them from the highly undesired late maturity ype. Pajerowska-Mukhtar et al., Genetics 181 :1 1 15 (2009).

Solanum tuberosum is a quite heterozygous tetraploid, which makes it difficult to er desirable traits between cultivars for expression in y. In addition, some W0 2014/153178 species of Solanum with natural resistance to insect pests and diseases, such as several found in Peru and Central America, are diploid and are not easily bred with the tetraploid Solanum tuberosum. The autotetraploid genome and asexual propagation used to breed potatoes creates challenges in developing new cultivars with desired traits. Resistance traits demonstrated in diploid species, e. g., Solanum astanum, are ssible for ng because the species has an endosperm e number of 1 compared to S. tuberosum has an endosperm balance number of 4.

The use of RTDSTM in potatoes has some of the advantages of enic genetic engineering over traditional breeding. RTDSTM allows lation of the endogenous AOSZ genes, eliminating the need for backcrossing required to remove undesirable traits in traditional breeding. RTDSTM allows introduction of mutations in genes conferring resistance and/or tolerance demonstrated by other species that do not have a compatible ploidy with S. tuberosum. In addition, RTDSTM has advantages over transgenic genetic engineering. RTDSTM is capable of manipulating the endogenous genes, as opposed to introducing a foreign transgene.

Rapid Trait Development System (RTDSTM) In any of the s aspects and embodiments of the itions and methods disclosed herein, mutations in genes and proteins may be made using, e. g., the Rapid Trait Development System (RTDSTM) technology developed by Cibus. In combination or alone, plants containing any of the mutations disclosed herein can form the basis of new en resistant and/or tolerant products. Also provided are seeds/vegetative material produced from the mutated plants in which the A082 genes are either homozygous or heterozygous for the mutations. The mutations disclosed herein can be in combination with any other mutation known or with ons discovered in the future.

TM is based In some embodiments, RTDS on altering a targeted gene by utilizing the cell’s own gene repair system to ically modify the gene sequence in situ and not insert foreign DNA and gene expression control sequences. This procedure may effect a precise change in the genetic sequence while the rest of the genome is left unaltered. In contrast to tional transgenic GMOs, there is no integration of foreign genetic material, nor is any foreign genetic material left in the plant. In many ments, the changes in the genetic sequence introduced by RTDSTM are not randomly inserted. Since ed genes remain in their native location, no random, uncontrolled or adverse pattern of expression occurs.

The RTDSTM process is carried out using a chemically synthesized oligonucleotide (a gene repair oligonucleobase (GRON)) which may be composed of both DNA and modified RNA bases as well as other chemical moieties, and is designed to hybridize at the targeted gene location to create a mismatched air(s). This ched base-pair acts as a signal to attract the cell’s own natural gene repair system to that site and t (replace, insert or delete) the designated nucleotide(s) within the gene. Once the correction process is complete the GRON molecule is degraded and the now-modified or repaired gene continues to be expressed under that gene’s normal endogenous control mechanisms.

] In one embodiment, the gene repair oligonucleobase is a mixed duplex oligonucleotide (MDON) in which the RNA-type nucleotides of the mixed duplex ucleotide are made RNase resistant by replacing the 2’-hydroxyl with a ﬂuoro, chloro or bromo functionality or by placing a substituent on the 2’-O. Suitable substituents include the substituents taught by the Kmiec II. Alternative substituents include the substituents taught by U.S. Pat. No. 5,334,711 (Sproat) and the tuents taught by patent publications EP 629 387 and EP 679 657 (collectively, the Martin Applications), which are hereby incorporated by reference. As used herein, a 2’-ﬂuoro, chloro or bromo derivative of a ribonucleotide or a ribonucleotide having a 2’-OH substituted with a substituent described in the Martin Applications or Sproat is termed a “2’-Substituted Ribonucleotide.” As used herein the term “RNA-type nucleotide” means a 2’-hydroxyl or 2’-Substituted tide that is linked to other nucleotides of a mixed duplex oligonucleotide by an unsubstituted phosphodiester linkage or any of the non- natural linkages taught by Kmiec I or Kmiec II. As used herein the term “deoxyribo-type nucleotide” means a nucleotide having a 2’-H, which can be linked to other nucleotides of a gene repair oligonucleobase by an unsubstituted phosphodiester linkage or any of the non-natural linkages taught by Kmiec I or Kmiec II.

In a particular embodiment of the present invention, the gene repair oligonucleobase is a mixed duplex oligonucleotides (MDON) that is linked solely by unsubstituted phosphodiester bonds. In alternative embodiments, the linkage is by tuted phosphodiesters, phosphodiester derivatives and non-phosphorus-based linkages as taught by Kmiec II. In yet another embodiment, each pe nucleotide in the mixed duplex oligonucleotide is a 2’-Substituted Nucleotide. Particular preferred embodiments of 2’-Substituted cleotides are 2’-f1uoro, 2’-methoxy, 2’-propyloxy, 2’-allyloxy, 2’-hydroxylethyloxy, 2’-methoxyethyloxy, 2’-ﬂuoropropyloxy and 2’- triﬂuoropropyloxy substituted ribonucleotides. More preferred embodiments of 2’- tuted cleotides are 2’-ﬂuoro, 2’-methoxy, 2’-methoxyethyloxy, and 2’- allyloxy substituted nucleotides. In another embodiment the mixed duplex oligonucleotide is linked by unsubstituted phosphodiester bonds.

Although mixed duplex oligonucleotides (MDONs) having only a single type of 2’-substituted RNA-type tide are more conveniently synthesized, the methods of the invention can be practiced with mixed duplex ucleotides having two or more types of RNA-type nucleotides. The function of an RNA segment may not be affected by an interruption caused by the introduction of a deoxynucleotide between two pe trinucleotides, accordingly, the term RNA segment encompasses terms such as rupted RNA segment.” An rrupted RNA segment is termed a contiguous RNA segment. In an alternative embodiment an RNA segment can contain alternating RNase-resistant and tituted 2’-OH nucleotides. The mixed duplex oligonucleotides preferably have fewer than 100 tides and more preferably fewer than 85 nucleotides, but more than 50 nucleotides. The first and second strands are Watson-Crick base paired. In one embodiment the strands of the mixed duplex oligonucleotide are covalently bonded by a linker, such as a single stranded hexa, penta or tetranucleotide so that the first and second strands are segments of a single oligonucleotide chain having a single 3’ and a single 5’ end. The 3’ and 5’ ends can be protected by the addition of a “hairpin cap” whereby the 3’ and 5’ terminal nucleotides are Watson-Crick paired to nt tides. A second hairpin cap can, additionally, be placed at the junction between the first and second strands distant from the 3’ and 5’ ends, so that the Watson-Crick pairing between the first and second strands is stabilized.

The first and second s contain two regions that are homologous with two fragments of the target gene, i.e., have the same sequence as the target gene. A homologous region contains the nucleotides of an RNA segment and may contain one or more DNA-type nucleotides of connecting DNA segment and may also contain DNA- type nucleotides that are not within the intervening DNA segment. The two regions of homology are separated by, and each is adjacent to, a region having a sequence that differs from the sequence of the target gene, termed a “heterologous region.” The logous region can contain one, two or three or more mismatched nucleotides. The mismatched nucleotides can be contiguous or alternatively can be separated by one, two, three, four, five, six, seven, eight, nine, ten, eleven, twelve, thirteen, fourteen or fifteen nucleotides that are homologous with the target gene. Alternatively, the heterologous region can also contain an insertion or one, two, three or of five or fewer nucleotides.

Alternatively, the sequence of the mixed duplex oligonucleotide may differ from the sequence of the target gene only by the deletion of one, two, three, or five or fewer nucleotides from the mixed duplex oligonucleotide. The length and on of the heterologous region is, in this case, deemed to be the length of the deletion, even though no nucleotides of the mixed duplex oligonucleotide are within the heterologous region.

The ce between the fragments of the target gene that are complementary to the two homologous regions is identical to the length of the heterologous region where a substitution or tutions is intended. When the heterologous region contains an insertion, the homologous s are y separated in the mixed duplex oligonucleotide farther than their complementary homologous nts are in the gene, and the converse is applicable when the heterologous region encodes a deletion.

The RNA segments of the mixed duplex oligonucleotides are each a part of a homologous region, i.e., a region that is identical in sequence to a fragment of the target gene, which segments together ably contain at least 13 RNA-type nucleotides and preferably from 16 to 25 pe nucleotides or yet more preferably 18-22 RNA-type nucleotides or most preferably 20 nucleotides. In one embodiment, RNA segments of the homology regions are separated by and adjacent to, i.e., “connected by” an ening DNA segment. In one embodiment, each nucleotide of the heterologous region is a nucleotide of the intervening DNA segment. An intervening DNA segment that contains the heterologous region of a mixed duplex oligonucleotide is termed a “mutator segment.” In another embodiment of the present disclosure, the gene repair oligonucleobase (GRON) is a single stranded oligodeoxynucleotide mutational vector (SSOMV), for example, such as disclosed in International Patent Application ; U.S. Pat. Nos. 6,271,360; 6,479,292; and 7,060,500 which are incorporated by reference in their entirety. The sequence of the SSOMV is based on the same principles as the mutational vectors described in U.S. Pat. Nos. 5,756,325; ,871,984; 5,760,012; 5,888,983; 5,795,972; 5,780,296; 5,945,339; 6,004,804; and 6,010,907 and in ational Publication Nos. WO 98/49350; WO 99/07865; WO 99/58723; WO 99/58702; and WO 99/40789. The sequence of the SSOMV contains two s that are homologous with the target sequence separated by a region that contains the desired c alteration termed the mutator . The mutator region can have a sequence that is the same length as the sequence that separates the homologous regions in the target sequence, but having a different sequence. Such a mutator region can cause a substitution. Alternatively, the homologous regions in the SSOMV can be contiguous to each other, while the regions in the target gene having the same sequence are separated by one, two or more nucleotides. Such an SSOMV causes a deletion from the target gene of the nucleotides that are absent from the SSOMV. Lastly, the sequence of the target gene that is identical to the homologous regions may be nt in the target gene but separated by one, two, or more nucleotides in the sequence of the SSOMV. Such an SSOMV causes an insertion in the sequence of the target gene.

The nucleotides of the SSOMV are deoxyribonucleotides that are linked by unmodified phosphodiester bonds except that the 3’ terminal and/or 5’ terminal internucleotide linkage or alternatively the two 3’ terminal and/or 5’ terminal internucleotide linkages can be a phosphorothioate or phosphoamidate. As used herein an internucleotide linkage is the linkage between nucleotides of the SSOMV and does not include the linkage between the 3’ end nucleotide or 5’ end nucleotide and a blocking substituent. In a specific ment the length of the SSOMV is between 21 and 55 deoxynucleotides and the lengths of the homology regions are, ingly, a total length of at least 20 ucleotides and at least two homology regions should each have lengths of at least 8 deoxynucleotides.

The SSOMV can be designed to be complementary to either the coding or the non-coding strand of the target gene. When the desired mutation is a substitution of a single base, it is preferred that both the r nucleotide and the targeted nucleotide be a pyrimidine. To the extent that is consistent with achieving the desired onal result, it is preferred that both the r nucleotide and the targeted nucleotide in the complementary strand be pyrimidines. Particularly preferred are SSOMVs that encode transversion mutations, i.e., a C or T r nucleotide is mismatched, tively, with a C or T nucleotide in the complementary strand.

In addition to the oligodeoxynucleotide, the SSOMV can contain a 5’ blocking tuent that is attached to the 5’ terminal carbons through a linker. The chemistry of the linker is not critical other than its length, which should ably be at least 6 atoms long and that the linker should be ﬂexible. A variety of non-toxic tuents such as biotin, cholesterol or other steroids or a non-intercalating cationic ﬂuorescent dye can be used. Particularly preferred reagents to make SSOMVs are the reagents sold as Cy3TM and Cy5TM by Glen Research, ng Va. (now GE Healthcare), which are blocked phosphoramidites that upon incorporation into an oligonucleotide yield 3,3,3’ ,3’- tetramethyl N,N’-isopropyl substituted indomonocarbocyanine and indodicarbocyanine dyes, respectively. Cy3TM is ularly red. When the indocarbocyanine is N- oxyalkyl substituted it can be conveniently linked to the 5’ terminal of the oligodeoxynucleotide as a phosphodiester with a 5’ terminal ate. The chemistry of the dye linker between the dye and the oligodeoxynucleotide is not critical and is chosen for synthetic convenience. When the commercially available Cy3TM phosphoramidite is used as directed, the resulting 5’ modification consists of a blocking substituent and linker together which are a N-hydroxypropyl, sphatidylpropyl 3,3,3’,3’-tetramethyl indomonocarbocyanine.

In a preferred embodiment the indocarbocyanine dye is tetra substituted at the 3 and 3’ positions of the indole rings. Without tions as to theory these substitutions t the dye from being an intercalating dye. The identity of the substituents at these ons is not critical. The SSOMV can in addition have a 3’ blocking tuent.

Again the chemistry of the 3’ blocking substituent is not critical.

The mutations herein described might also be obtained by mutagenesis (random, somatic or directed) and other DNA editing or recombination logies including, but not limited to, gene targeting using site-specific homologous recombination by zinc finger nucleases, meganucleases or other nucleases.

Delivery of Gene Repair Oligonucleobases into Plant Cells Any ly known method used to transform a plant cell can be used for delivering the gene repair oligonucleobases. Illustrative methods are described below.

Microcarriers and Microfibers The use of metallic microcarriers (microspheres) for introducing large fragments of DNA into plant cells having cellulose cell walls by projectile penetration is well known to those skilled in the relevant art (henceforth biolistic delivery). U.S. Pat.

Nos. 4,945,050; 5,100,792 and 5,204,253 describe general ques for selecting microcarriers and devices for projecting them.

Specific conditions for using microcarriers in the methods of the present invention are described in International Publication WO 99/07865. In an illustrative que, ice cold microcarriers (60 mg/mL), mixed duplex oligonucleotide (60 mg/mL) 2.5 M CaClz and 0.1 M dine are added in that order; the mixture gently agitated, e. g., by vortexing, for 10 minutes and then left at room temperature for 10 minutes, pon the microcarriers are diluted in 5 volumes of ethanol, centrifuged and resuspended in 100% ethanol. Good results can be obtained with a concentration in the adhering solution of 8-10 ug/uL microcarriers, 14-17 ug/mL mixed duplex oligonucleotide, 1.1-1.4 M CaClz and 18-22 mM spermidine. Optimal results were observed under the conditions of 8 ug/uL microcarriers, 16.5 ug/mL mixed duplex oligonucleotide, 1.3 M CaClz and 21 mM spermidine.

Gene repair oligonucleobases can also be introduced into plant cells for the practice of the t invention using microfibers to penetrate the cell wall and cell membrane. U.S. Pat. No. 5,302,523 to Coffee et al. describes the use of 30 X 0.5 um and X 0.3 um silicon carbide fibers to tate ormation of sion maize es of Black Mexican Sweet. Any mechanical technique that can be used to introduce DNA for transformation of a plant cell using microfibers can be used to r gene repair oligonucleobases for transmutation.

An illustrative technique for microfiber delivery of a gene repair oligonucleobase is as s: Sterile microfibers (2 ug) are suspended in 150 uL of plant culture medium containing about 10 ug of a mixed duplex oligonucleotide. A suspension culture is d to settle and equal volumes of packed cells and the sterile fiber/nucleotide suspension are vortexed for 10 minutes and plated. Selective media are applied immediately or with a delay of up to about 120 h as is appropriate for the particular trait.

Protoplast Electroporation In an alternative embodiment, the gene repair oligonucleobases can be delivered to the plant cell by electroporation of a protoplast derived from a plant part or sion of plant cells. The protoplasts are formed by enzymatic ent of a plant part, particularly a leaf, according to techniques well known to those skilled in the art.

See, e.g., Gallois et al., 1996, Methods in Molecular Biology 55:89-107, Humana Press, Totowa, N.J.; Kipp et al., 1999, Methods in Molecular Biology 133:213-221, Humana Press, Totowa, NJ. The protoplasts need not be cultured in growth media prior to electroporation. Illustrative conditions for electroporation are 3X105 protoplasts in a total volume of 0.3 mL with a concentration of gene repair oligonucleobase of between 0.6-4 ug/mL.

Protoplast PEG-mediated DNA uptake WO 53178 In an alternative embodiment, nucleic acids are taken up by plant protoplasts in the presence of the membrane-modifying agent polyethylene glycol, according to techniques well known to those skilled in the art (see, e. g., Gharti-Chhetri et al., Physiol.

Plant. 85:345-351 (1992); Datta et al., Plant Molec. Biol. 20:619-629 (1992)).

Microinjection In an alternative embodiment, the gene repair oligonucleobases can be delivered by injecting it with a microcapillary into plant cells or into protoplasts (see, e. g., Miki B. et al., Meth. Cell Science 12:139-144 (1989); Schnorf M., et al., Transgen. Res. 1:23-30 (1991)).

Transgenics ] In any of the various aspects and ments of the compositions and methods disclosed herein, mutations in genes and ns may be made using, e. g., enic technology. In some embodiments, the compositions and methods include a plant or plant cell having a transformed nucleic acid construct ing a er operably linked to an AOS2 nucleotide disclosed herein. The methods disclosed herein may include introducing an AOS2 nucleic acid construct disclosed herein into at least one plant cell and regenerating a transformed plant therefrom. The nucleic acid construct comprises at least one nucleotide sequence that encodes a pathogen resistant and/or tolerant AOS2 protein as disclosed herein, particularly the nucleotide sequences of set forth in Figures 2 and 4, and fragments and variants thereof. The methods further involve the use of a promoter that is capable of driving gene expression in a plant cell. In one embodiment, such a er is a constitutive promoter or a tissue-preferred promoter. A plant ed by these methods may have increased or stabilized AOS2 activity and/or elevated jasmonic acid and/or 12-oxo-phytodienoic acid (OPDA) levels leading to enhanced resistance and/or tolerance to ens when compared to an untransformed plant. Thus, the methods find use in enhancing or increasing the resistance and/or tolerance of a plant to at least one pathogen.

In one embodiment, the methods for ing a pathogen resistant and/or tolerant plant include transforming a plant cell with a nucleic acid construct comprising a nucleotide sequence operably linked to a promoter that drives sion in a plant cell and regenerating a transformed plant from said transformed plant cell. The nucleotide sequence is ed from those nucleotide sequences that encode the en resistant W0 2014/153178 PCT/U82014/029434 and/or tolerant A082 disclosed herein, particularly the nucleotide sequences set forth in Figures 2 and 4, and fragments and variants thereof. A pathogen resistant and/or tolerant plant produced by this method comprises ed resistance and/or tolerance, compared to an untransformed plant, to at least one pathogen, e. g., hthora infestans.

] The disclosed nucleic acid molecules can be used in nucleic acid constructs for the transformation of plants, for example, crop plants, such as Solanum tuberosum. In one embodiment, such nucleic acid constructs containing the nucleic acid molecules of the t disclosure can be used to produce transgenic plants to provide for resistance and/or tolerance to pathogens, such as Phytophthora infestans. The nucleic acid constructs can be used in expression cassettes, expression vectors, transformation vectors, ds and the like. The enic plants ed following transformation with such constructs demonstrate sed resistance and/or tolerance to pathogens such as, e. g., Phytophthora infestans. ucts The nucleic acid molecules disclosed herein (e. g., mutated A082 genes) can be used in the production of recombinant nucleic acid constructs. In one embodiment, the nucleic acid molecules of the invention can be used in the preparation of nucleic acid constructs, for example, expression cassettes for expression in the plant of interest.

Expression cassettes may include regulatory sequences operably linked to the A082 nucleic acid sequences disclosed herein. The cassette may additionally contain at least one additional gene to be nsformed into the organism. Alternatively, the additional gene(s) can be provided on multiple expression cassettes.

The nucleic acid ucts may be provided with a plurality of restriction sites for ion of the A082 nucleic acid sequence to be under the riptional tion of the regulatory regions. The nucleic acid constructs may additionally contain nucleic acid molecules ng for able marker genes.

Any promoter can be used in the production of the nucleic acid constructs.

The promoter may be native or analogous, or foreign or heterologous, to the plant host and/or to the A082 nucleic acid sequences disclosed herein. Additionally, the promoter may be the natural sequence or alternatively a synthetic sequence. Where the promoter is “foreign” or “heterologous” to the plant host, it is intended that the promoter is not found in the native plant into which the promoter is introduced. Where the promoter is W0 2014/153178 PCT/U82014/029434 “foreign” or “heterologous” to the A082 nucleic acid sequences disclosed , it is intended that the promoter is not the native or lly occurring promoter for the operably linked A082 nucleic acid sequences disclosed herein. As used herein, a ic gene ses a coding sequence ly linked to a transcription initiation region that is heterologous to the coding sequence.

In some embodiments, the A082 nucleic acid sequences disclosed herein are expressed using heterologous promoters, the native er sequences may be used in the preparation of the constructs. 8uch ucts would change expression levels of the A082 protein in the plant or plant cell. Thus, the phenotype of the plant or plant cell is altered.

Any promoter can be used in the preparation of constructs to control the expression of the A082 coding sequence, such as promoters providing for constitutive, tissue-preferred, inducible, or other promoters for expression in plants. Constitutive promoters include, for example, the core promoter of the Rsyn7 promoter and other constitutive promoters disclosed in WC 99/43 838 and US. Patent No. 050; the core CaMV 358 promoter (Odell et al. (1985) Nature 313:810-812); rice actin (McElroy et al. (1990) Plant Cell 2:163-171); ubiquitin (Christensen et al. (1989) Plant Mol. Biol. 12:619-632 and ensen et al. (1992) Plant Mol. Biol. 18:675-689); pEMU (Last et al. (1991) Theor. Appl. Genet. 81:581-588); MA8 (Velten et al. (1984) EMBO J. 32723- 2730); AL8 promoter (US. Patent No. 026), and the like. Other constitutive promoters include, for example, US. Patent Nos. 5,608,149; 5,608,144; 5,604,121; ,569,597; 5,466,785; 5,399,680; 5,268,463; 5,608,142; and 6,177,611.

Tissue-preferred promoters can be utilized to direct A082 expression within a particular plant tissue. 8uch tissue-preferred promoters include, but are not limited to, leaf-preferred promoters, root-preferred ers, seed-preferred promoters, and stem- preferred promoters. -preferred promoters include Yamamoto et al. (1997) Plant J. 12(2):255-265; Kawamata et al. (1997) Plant Cell Physiol. 38(7):792-803; Hansen et al. (1997) Mol. Gen Genet. 254(3):337-343; Russell et al. (1997) Transgenic Res. 6(2):157- 168; Rinehart et al. (1996) Plant Physiol. 1 12(3):1331-1341; Van Camp et al. (1996) Plant Physiol. 1 12(2):525-535; Canevascini et al. (1996) Plant Physiol. 112(2): 513-524; Yamamoto et al. (1994) Plant Cell Physiol. 35(5):773-778; Lam (1994) Results Probl.

Cell . 20:181-196; Orozco et al. (1993) Plant Mol Biol. 23(6):1129-1138; Matsuoka W0 2014/153178 et al. (1993) Proc Natl. Acad. Sci. USA 90(20):9586- 9590; and Guevara-Garcia et al. (1993) Plant J. 4(3):495-505.

The nucleic acid constructs may also include transcription termination regions.

Where transcription ations regions are used, any ation region may be used in the preparation of the nucleic acid constructs. For example, the termination region may be native to the transcriptional initiation region, may be native to the operably linked AOS2 sequence of st, may be native to the plant host, or may be derived from another source (i.e., foreign or heterologous to the promoter, the A082 nucleic acid molecule of interest, the plant host, or any combination thereof). Examples of termination regions that are available for use in the constructs of the present invention e those from the Ti-plasmid of A. tumefaciens, such as the octopine synthase and nopaline synthase termination s. See also Guerineau et al. (1991) Mol. Gen. Genet. 262:141-144; Proudfoot (1991) Cell -674; Sanfacon et al. (1991) Genes Dev. :141-149; Mogen et al. (1990) Plant Cell 2:1261-1272; Munroe et al. (1990) Gene -158; Ballas et al. (1989) Nucleic Acids Res. 17:7891-7903; and Joshi et al. (1987) Nucleic Acid Res. 15:9627-9639.

In some embodiments, the nucleic acids may be zed for increased expression in the transformed plant. That is, the nucleic acids encoding the mutant AOS2 proteins can be synthesized using plant-preferred codons for improved expression. See, e. g., ll and Gowri (1990) Plant Physiol. 92: 1-11 for a discussion of host-preferred codon usage. Methods are available in the art for synthesizing plant-preferred genes.

See, e.g., U.S. Patent Nos. 5,380,831, and 5,436,391, and Murray et al. (1989) Nucleic Acids Res. 17:477-498.

In addition, other sequence modifications can be made to the nucleic acid sequences disclosed herein. For example, additional sequence modifications enhance gene expression in a cellular host. These include elimination of sequences encoding spurious polyadenylation signals, exon/intron splice site signals, transposon-like repeats, and other such well-characterized sequences that may be deleterious to gene expression.

The G-C content of the sequence may also be adjusted to levels average for a target cellular host, as calculated by reference to known genes expressed in the host cell. In addition, the sequence can be ed to avoid predicted n secondary mRNA structures.

Other nucleic acid sequences may also be used in the preparation of the ucts of the present invention, for example to enhance the expression of the AOS2 coding sequence. Such nucleic acid sequences include intron 1 of the maize Adh1 gene (Callis et al. (1987) Genes and Development 1:1183-1200), and leader sequences, (W- ce) from the Tobacco Mosaic virus (TMV), Maize Chlorotic Mottle Virus and Alfalfa Mosaic Virus (Gallie et al., (1987) Nucleic Acid Res. 3-8711, and Skuzeski et al., (1990) Plant Mol. Biol. 15:65-79). The first intron from the shrunken-1 locus of maize has been shown to increase expression of genes in ic gene constructs. U.S. Pat. Nos. 5,424,412 and 5,593,874 disclose the use of specific introns in gene expression ucts, and Gallie et al., Plant l. 9-939 (1994)) have also shown that introns are useful for ting gene expression on a tissue specific basis. To further enhance or to optimize AOS2 gene expression, the plant expression vectors disclosed herein may also contain DNA sequences containing matrix attachment regions (MARs). Plant cells transformed with such modified expression systems, then, may exhibit overexpression or constitutive expression of a nucleotide sequence of the ion.

The expression constructs disclosed herein can also include nucleic acid sequences capable of directing the expression of the AOS2 sequence to the chloroplast.

Such nucleic acid sequences include chloroplast targeting sequences that encodes a chloroplast transit peptide to direct the gene product of interest to plant cell chloroplasts.

Such transit peptides are known in the art. With respect to plast-targeting sequences, “operably linked” means that the nucleic acid sequence encoding a transit peptide (i.e., the chloroplast-targeting sequence) is linked to the AOS2 nucleic acid le of the invention such that the two sequences are contiguous and in the same reading frame. See, e.g., Von Heijne et al. (1991) Plant Mol. Biol. Rep. 126; Clark et al. (1989) J. Biol. Chem. 264:17544-17550; Della-Cioppa et al. (1987) Plant Physiol. 84:965-968; Romer et al. (1993) Biochem. Biophys. Res. Commun. 196:1414-1421; and Shah et al. (1986) Science 233:478-481. While the AOS2 proteins disclosed herein may include a native chloroplast transit peptide, any chloroplast transit peptide known in the art can be fused to the amino acid sequence of a mature AOS2 protein of the invention by ly g a choloroplast-targeting sequence to the 5'-end of a nucleotide sequence encoding a mature AOS2 protein of the invention.

Chloroplast targeting sequences are known in the art and include the chloroplast small t of ribulose-1,5-bisphosphate carboxylase (Rubisco) (de Castro Silva Filho et al. (1996) Plant Mol. Biol. 30:769-780; Schnell et al. (1991) J. Biol. Chem. 266(5):3335-3342); 5- yruvyl)shikimatephosphate synthase (EPSPS) (Archer et al. (1990) J. Bioenerg. Biomemb. 22(6):789-810); tryptophan synthase (Zhao et al. (1995) J. Biol. Chem. 270(1 1):6081- 6087); plastocyanin (Lawrence et al. (1997) J. Biol. Chem. 272(33):20357-20363); chorismate synthase (Schmidt et al. (1993) J. Biol. Chem. 268(36):27447-27457); and the light harvesting chlorophyll a/b binding protein (LHBP) (Lamppa et al. (1988) J. Biol. Chem. 263:14996-14999). See also Von Heijne et al. (1991) Plant Mol. Biol. Rep. 9:104-126; Clark et al. (1989) J. Biol. Chem. 264:17544- 17550; Cioppa et al. (1987) Plant Physiol. 84:965-968; Romer et al. (1993) Biochem. s. Res. . 14-1421; and Shah et al. (1986) Science 233:478-481.

In another embodiment, the nucleic acid ucts may be ed to direct the expression of the mutant AOS2 coding sequence from the plant cell plast.

Methods for transformation of chloroplasts are known in the art. See, e. g., Svab et al. (1990) Proc. Natl. Acad. Sci. USA 87:8526-8530; Svab and Maliga (1993) Proc. Natl.

Acad. Sci. USA 90:913-917; Svab and Maliga (1993) EMBO J. 12:601-606. The method relies on particle gun delivery of DNA containing a selectable marker and targeting of the DNA to the plastid genome through homologous ination. Additionally, plastid transformation can be accomplished by transactivation of a silent plastid-borne transgene by tissue-preferred expression of a nuclear-encoded and plastid-directed RNA polymerase. Such a system has been reported in McBride et al. (1994) Proc. Natl. Acad.

Sci. USA 91:7301-7305.

The nucleic acids of interest to be targeted to the chloroplast may be optimized for expression in the chloroplast to account for differences in codon usage between the plant nucleus and this organelle. In this manner, the nucleic acids of interest may be sized using chloroplast-preferred codons. See, e. g., US. Pat. No. 5,380,831, herein incorporated by reference.

The nucleic acid constructs can be used to transform plant cells and regenerate transgenic plants comprising the mutant AOS2 coding sequences. Numerous plant transformation vectors and methods for transforming plants are available. See, e. g., US.

The disclosed constructs comprising the AOS2 nucleic acid ces disclosed herein can be used in various methods to produce transgenic host cells, such as bacteria, yeast, and to orm plant cells and in some cases regenerate transgenic plants. For example, methods of producing a transgenic crop plant containing the AOS2 mutant proteins disclosed herein, where expression of the nucleic acid(s) in the plant results in pathogen resistance and/or tolerance as compared to wild-type plants or to known AOS2 mutant type plants comprising: (a) ucing into a plant cell an expression vector comprising nucleic acid encoding a mutant AOS2 n, and (b) generating from the plant cell a transgenic plant which is pathogen ant and/or tolerant.

] AOS2 Mutations The compositions and methods may relate at least in part to mutations in an AOS2 gene, for example ons that render a plant resistant or tolerant to a pathogen.

The compositions and methods also in certain embodiments relate to the use of a gene repair oligonucleobase to make a desired mutation in the chromosomal or episomal ces of a plant in the gene encoding for an AOS2 protein. The mutated protein, which may in some embodiments substantially maintain the catalytic activity of the wild- W0 2014/153178 PCT/U82014/029434 type protein, ng for sed resistance and/or tolerance of the plant to a pathogen, and thus in some embodiments ng for substantially normal or altered growth or development of the plant, its , tissues, or cells as compared to the wild-type plant irrespective of the presence or absence of the en. The compositions and methods also relate to a non-transgenic plant cell in which an A082 gene has been mutated, a non- transgenic plant regenerated therefrom, as well as a plant resulting from a cross using a rated ansgenic plant to a plant haVing a mutation in a different A082 gene or in the same A082 gene, for example.

The gene repair oligonucleobase can be introduced into a plant cell using any method commonly used in the art, including but not d to, microcarriers (biolistic delivery), microfibers, hylene glycol (PEG)-mediated uptake, electroporation, and microinj ection.

Also provided are methods and compositions related to the culture of cells mutated according to methods as disclosed herein in order to obtain a plant that produces seeds, henceforth a “fertile plant,” and the tion of seeds and additional plants from such a fertile plant.

Also provided are methods and compositions related to the culture of cells mutated ing to methods as sed herein in order to obtain a plant that produces ntially normal tubers with substantially normal yield such that substantially normal plants arise from a tuber or piece of a potato tuber containing at least one or two eyes (dormant buds), often referred to as seed potatoes.

Also provided are mutations in the A082 gene that confer resistance and/or tolerance to a nt pathogen to a plant or wherein the mutated AOS2 gene has substantially the same or altered enzymatic activity as compared to wild-type AOS2.

Selection of Pathogen ant Plants and Application of Pathogens Plants and plant cells can be tested for resistance and/or tolerance to a pathogen using commonly known s in the art, e.g., by growing the plant or plant cell in the presence of a pathogen and measuring the rate of growth as compared to the growth rate in the absence of the pathogen. Pathogen challenge for selection of resistant and/or tolerant plants may be achieved by using either sporangial or zoospore application of the pathogen. Resistance levels of the plant with these challenges can be rated according various methods such as determining the rate of increase in pathogen DNA from infected plant material, the rate of lesion size progression etc.

As used herein, substantially normal growth of a plant, plant organ, plant tissue or plant cell is defined as a growth rate or rate of cell division of the plant, plant organ, plant tissue, or plant cell that is at least 35%, at least 50%, at least 60%, or at least 75% of the growth rate or rate of cell division in a corresponding plant, plant organ, plant tissue or plant cell expressing the wild-type AOS2 protein.

As used herein, ntially normal development of a plant, plant organ, plant tissue or plant cell is defined as the occurrence of one or more development events in the plant, plant organ, plant tissue or plant cell that are substantially the same as those occurring in a corresponding plant, plant organ, plant tissue or plant cell sing the ype AOS2 protein.

] In certain embodiments plant organs provided herein include, but are not d to, leaves, stems, roots, vegetative buds, ﬂoral buds, meristems, embryos, cotyledons, endosperm, sepals, petals, pistils, carpels, stamens, s, microspores, pollen, pollen tubes, ovules, ovaries and fruits, or sections, slices or discs taken therefrom. Plant tissues include, but are not limited to, callus tissues, ground tissues, vascular tissues, storage tissues, meristematic tissues, leaf tissues, shoot tissues, root tissues, gall tissues, plant tumor tissues, and reproductive tissues. Plant cells include, but are not limited to, isolated cells with cell walls, sly sized aggregates thereof, and protoplasts.

Plants are substantially “tolerant” to a relevant pathogen when they are subjected to it and provide a dose/response curve which is shifted to the right when compared with that provided by similarly subjected non-tolerant like plant. Such dose/response curves have “dose” plotted on the X-axis and “percentage kill”, genic effect”, etc., plotted on the y-axis. Tolerant plants will require more pathogen than non-tolerant like plants in order to produce a given enic effect.

Plants that are substantially “resistant” to the pathogen exhibit few, if any, ic, lytic, tic or other lesions, when ted to a pathogen at concentrations and rates which are l of pathogen exposure in the field. Plants which are resistant to a pathogen are also tolerant of the pathogen.

WO 53178 Polymerase Chain Reaction Methods for Detecting and Quantifying Pathogens in Plants Host resistance to a pathogen can be determined utilizing methods already established and known to those skilled in the art. Generally, diverse methods are commonly utilized for diverse pathogens but in general, the following can be utilized for application toward fungal and bacterial pathogens.

] Pathogen resistance and/or tolerance may be determined by monitoring the presence and amount of pathogen specific nucleic acid in a plant. For example, leaﬂets in a plant are inoculated with 10 uL droplets of sporangial suspension (30-40 sporangia/uL) on both sides of the midrib. Oberhagemann, P., et al. Mol. Breed. Vol. 5, p. 399-415 (1999). Disease symptoms may be scored 7 days post infection. DNA is extracted from infected plant al. Pathogen growth is monitored using Phytophthora infestans— ribosomal DNA specific primers as described in (exemplary forward primer sequence: 5’- CATAGAAGGTAGA-3’ and exemplary reverse primer ce: 5’- TAACCGACCAAGTAGTAAA-3’). Intensities of Phytophthora infestans amplicons are ated relative to potato tubulin DNA bands. Band ities are quantified and converted to arbitrary units ve to the absolute values obtained from control plants.

Judelson, HS, et al. Phytopathology, vol. 90, p. 1112-1119 (2000).

Pathogen resistance levels on the potato plants of interest can be assessed by the nge of the plants with Phytophthora ans or other pathogen of interest. For Phytophthora ans, leaves of 6 — 8 week old plants will be detached and placed with the abaxial side facing upward on 4% water agar plates. Leaves are inoculated with a drop of sporangial suspension (at 40,000-100,000 gia/mL) using a Pasteur pipette on the abaxial side of the leaf. Plates will be placed in an 18°C incubator with 12 h photoperiod.

Disease development will be scored 6 days post inoculation and as necessary according to published methods as in Vleeshouwers et al. (2000) Physiol and Mol Plant Pathology, vol. 57, p. 35 — 42; Vleeshouwers et al. (1999) Europ J of Plant Pathology, vol. 105, p. 241-250; Oberhagemann et al. (1999) lar Breeding, vol. 5, p.399-415.

For fungal infection assays, ion level assessment will be carried out according to published methods for each fungal-host interactions. References include Rogers et al. (1994) Plant Cell, vol. 6, p. 935 — 945; Valent et al. (1991) Genetics, vol. 127, p. 87- 101; Thomas et al. (1997) Plant Cell, vol. 9, p. 2209 — 2224.

Typically, for a sporulating fungus, inoculations are carried out utilizing an inoculum containing spores of fungus of interest at a desired tration. This inoculum will be sprayed on a plant at a specific developmental stage (ex: prior to 4th leaf emergence/ 6-8 week old etc.). The inoculated plants will be incubated under high humidity conditions for 24 h post inoculation and then will be transferred to desired growth ions under day — night cycles appropriate for the host plant . The ion ity will be assessed typically 3-4 days after infection and scored according to ished s for the host-pathogen system. Typically, non-sporulating s will be assessed as “resistant” reactions while sporulating lesions are considered as “susceptible” reactions. The latter are rated for infection severity according to size and appearance of the s.

For assessment of disease severity related to bacterial pathogens, published methods for each bacterial species will be utilized as mentioned in Elibox, W., et al. (2008) Phytopathology, vol. 98, p. 421-426; Chaudhry et al. (2006) — Pakistan J of Botany, vol. 38 (1), p. 193 — 203; Zhao et al. (2005) J of iology, vol. 187, p. 8088.

Typically, for bacterial pathogens, a bacterial suspension at a pre-determined density (ex: 5x104 colony forming units) will be infiltrated into leaves of host plant at a particular developmental stage (ex: 3 week old plants). Inoculated plants are maintained at high humidity for 3-4 days and the infection ty is assessed by sampling two to three leaf discs that are ground up and resulting supernatant plated on bacterial growth media to enumerate the bacterial colony forming units arising from the infected plant material.

Infection severity of the converted plant will be assessed by evaluating the colony forming units arising from the infected tissue of the converted plant compared with those arising from the infected tissue of the wildtype plants.

Example 1: Increase of plant pathogen resistance using RTDSTM logy Evaluation of cultivars of interest for genotype at the AOS2 gene loci Utilizing skills of the trade that are known to those trained in the art, potato cultivars of interest are subjected to genotyping as follows: Genomic DNA of plant cultivars of interest were extracted with known methods and was subjected to rase Chain Reaction (PCR) mediated gene amplification to isolate all AOS2 alleles present within the said c DNA samples. PCR primers used for the ication are as s: Forward primer 5’-CACCTTTGTATCACTAACATTACCCATCC-3’ (SEQ ID NO: 51) and Reverse primer 5’-GCATGTGTTGCTTGTTCTTATAATTTCAG—3’ (SEQ ID NO: 52). The amplified fragments were cloned into TOPO 2.l vector (Invitrogen Corporation, Carlsbad, CA) and subjected to cing at 12 clones per amplification.

Utilizing Vector NTI software is package (Invitrogen Corporation, Carlsbad, CA), the resulting sequences were aligned with the reference sequence (SEQ ID NO 2) and polymorphic sites were determined. Translation of the said nucleic acid sequences to n coding sequence was also carried out utilizing the Vector NTI sequence is software and the resulting sequences were compared with the reference protein sequence (SEQ ID NO 1) to identify polymorphic amino acids. All detected amino acid polymorphisms and their positions in the protein ces collected to date are provided in Table l. The amino acid positions are designated in accordance to the amino acid positions of the reference protein ce given by SEQ ID NO 1.

Characterization of the biochemical activities of AOS2 alleles (In vitro) The nucleic acid of the identified AOS2 alleles were PCR amplified with the primers as described earlier but with added Xma I and Pst I sites to the Forward and Reverse primers, respectively, to introduce Xma I and Pst I sites at the 5’ and 3’ ends respectively of the s to facilitate cloning of the amplified products into the pQE30 vector for heterologous expression in E. 6011' (M15 strain, Qiagen Inc., Valencia, CA).

The PCR ied fragments were digested with Xma I and Pst I restriction enzymes and were cloned into similarly digested pQE30b vector cted to Site Directed W0 53178 Mutagenesis to insert a nucleotide 5’ to the Xma I site such that any gene fragment cloned into the Xma I site is in frame with the coding sequence of the pQE30 vector) and clones were selected by transformation into E. coli strain XL-l Blue. The ing sion plasmids were extracted from XL—l Blue cells and subjected to colony PCR and sequencing to verify g and absence of any hifts. The verified clones were transformed into M15 cells (Qiagen Inc., Valencia, CA) and used for protein expression analysis.

For protein expression analyses, 500 uL of overnight 5 mL cultures of s of interest (e. g. vector only strain ing a plasmid without an AOS2 gene and strain of interest harboring a single allele of A082 gene,) were each inoculated into a 10 mL of LB medium supplemented with carbenicillin (100 ug/mL) and Kanamycin (25 ug/mL).

The cultures were incubated at 37 0C with 250 rpm agitation until the ance at 600 nm (A600) reached desired OD units (e.g., 0.6-0.8 OD units). Then the cells were induced for n expression with 1 mM of IPTG and incubated at d ature (e. g., 12°C) with 100 rpm agitation for the desired time period (e. g., 3-7 days). Protein expression was monitored with SDS PAGE gel electrophoresis and by spectral analysis for the expression of a Type I cytochromoe P450 protein. AOS2 protein purification is carried out utilizing commercially available Ni NTA binding columns according to manufacturer instructions (Thermo Scientific, Rockford, IL).

Biochemical Assay for the characterization of the catalytic activity of the A082 proteins The purified proteins expressed in E. coli are used to assay for the catalytic activity of the proteins encoded by the identified different s of the A082 gene. The assay is carried out according to published protocols (Schreier and Lorenz (1982) Z.

Naturforsch, Vol. 37 0C, p. 165). In general, 13S-hydroperoxy-9Z,11E-octadecadienoic acid (13-HPODE) and 13S-hydroperoxy-9Z,11E,15Z-octadecatrienoic acid (HPOTrE) act as the substrate for the enzyme assay and a reference sample with no added enzyme serves as negative control. To assess the catalytic ty of the different proteins encoded by the different AOS2 alleles, a known amount of purified protein normalized by spectral analysis or other means is determined with 3 — 13 uM solution of substrate in 0.1 M Phosphate buffer pH 6.0. The rate of decrease in absorbance at A234 is monitored over time and resulting kinetic data is used to calculate the specific activity of each of the proteins of interest. Enzymes with the highest specific activities are considered as those of interest and the amino acid sequences of such enzymes are compared to those with lower specific activities to identify the specific amino acid positions that confer superior catalytic activity to the A082 proteins.

To evaluate the effect of the G231T mutation, the 691/692 nucleotides (nt) of StAOS2 alleles StAOS2_CB17 and StAOS2_CB18 of Bintje were converted from G/G to A/C using site directed mutagenesis (SDM) leading to a G231T tion in the respective AOS2 proteins. The amino acid (aa) polymorphisms found throughout these AOS2 ns are given in Table 2. Those clones were subjected to biochemical assay as described above and the specific activities of those proteins and those altered at the 231 aa position are given in Table 3.

Table 2: The pe differences among amino acid positions 48, 76, 231, 328, 423 and 494 of StAOS2 alleles of Bintje subjected to the biochemical activity assay.

The data is provided in Table 4.

The data provides that a G231T transition when combined with L328V mutation leads to a decrease in AOS2 protein specific ty and is indicative that the interplay between the aa profiles at these two positions impact the activity of the AOS2 protein.

In vitro activity assays were also ed to test the effect of D76N mutation in StAOS2_CB19. StAOS2_CB19 was subjected to SDM to yield StAOS2_CB19_D76N allele with the 76th residue in AOS2 protein converted to an Asparagine (N) from Aspartic acid (D). These were ted for ic activity differences utilizing the methods described above. Data collected from three independent trials indicated that the D76N mutation led to an approximately 30% se in enzyme activity.

Those alleles with or catalytic activity are chosen for in planta assays.

Characterization of the biochemical activities of AOS2 alleles (In vivo) To evaluate the hypothesis that those AOS2 ns with superior in vitro biochemical ty will also have superior in planta biochemical activity, those AOS2 alleles that t or specific activities are cloned into a plant binary vector under a constitutive or Arabidopsis AOS2 promoter. Utilizing Agrobacterium tumefaciens mediated transformation method, these constructs are transformed into Arabidopsis thaliana AOS2 gene disrupted plant line CS6149 (TAIR, http://www.arabidopsis.org/) via established methods (Bent et al. (2000) Plant Physiol, vol. 124, p. 1540). Transformants are identified by appropriate selection (dependent on the slectable marker present in the binary vector — i.e., kanamycin for the nptII gene as the able marker), molecular means, as well as the ability of the introduced AOS2 genes to complement the A082 deficient phenotype of abnormal pollination/silique development as a result of male sterility caused by the absence of a functional AOS2 gene. The A082 gene complemented plant lines are assessed for JA and/or OPDA levels at basal and ng conditions using established s b et al. (2008), PLoS ONE, vol 3: p.el904; Schmelz et al. (2003) Plant Physiol, vol 133: p 295; Engelberth et al. (2003) Anal Biochem, vol. 312, p 242.). Alternatively, complemented lines are utilized for plant disease assays utilizing pathogens of Arabidopsis such as Erwim'a carotovora or ssp. carotovora or Hyaloperonospora arabidopsidis and/or others to test the hypothesis that higher JA levels or AOS2 catalytic ty leads to enhanced resistance and/or tolerance to ens.

To evaluate the impact of aa polymorphisms of A082 protein on in planta jasmonic acid (JA) accumulation, two alleles of Bintje potato cultivar, StAOS2_CB18_G231T, driven by the Arabidopsis thaliana AtAOSZ promoter were used to complement the null mutant phenotype of the A. thaliana a0s2 mutant plants. The resulting transgenics were advanced to the T3 tion to obtain homozygotes and resulting plants were subjected to JA fication studies as per bed methods b et al. (2008), PLoS ONE, vol 3: p.el904; Schmelz et al. (2003) Plant Physiol, vol 133: p 295; Engelberth et al. (2003) Anal m, vol. 312, p 242). The results are shown in Table 5.

Table 5: The JA accumulation pattern in the Arabidopsis thaliana transgenic lines harboring StAOS2_CB19 or StAOS2_Cb18_G231T alleles. Average JA amounts shown represent JA levels present in Arabidopsis leaf tissue under basal expression levels at ng per gram fresh weight. The results shown are averages of two replicate samples containing multiple leaves.

This data is consistent with that presented in Table 3 providing that the interplay between the 231 and 328 aa of the A082 protein play a role in modulating the A082 protein activity. This data also validates the in vitro collected data in planta bed herein, indicating that the 231 and 328 positions of the A082 protein plays a role in modulating the JA levels in planta. 2014/029434 To evaluate the effect of the StAOS2 genotype and subsequent aa profile of the A082 protein on disease tolerance, the A. thaliana transgenic plants harboring the StAOS2 Alleles, StAOS2_CB18_G231T and StAOS2_CB19 of Bintje potato cultivar were inoculated with Erwinia carotovora ssp. carotovora (Ecc) at 5x104 cfu/ml according to established methods la et al., (2003) Arabidopsis, 16: MPMI, 179- 187). At various time points post inoculation, leaf samples were red and bacterial titer was quantified. Bacterial growth was significantly lower in A. na transgenics harboring StAOS2_CB18_G231T than those with the StAOS2_CB19 allele.

Evaluation of the effect of the 231 aa profile on the tolerance of potato to Phytophthora infestans To correlate a functional distinction to the genotype differences in StA052 gene alleles and test the hypothesis that StAOSZ gene alleles with A/C at the 691/692 nt confers increased tolerance when compared to those that contain G/G at these positions, two variants of the StAOS2 allele, _CB18 and StAOS2_CB18_G231T, with G/G and A/C at the 691/692 nt positions, respectively, were over expressed in potato under the 358 promoter. Some of the resulting lines were tested for tolerance to Phytophthora ans using the standard detached leaf assay. In short, for each tested allele, leaves from approximately six independent 4-8 week old transgenic potato plants grown in soil were detached and ated with 300 spores at 4 locations on the abaxial side of the leaf. The leaves were kept in dark for 24 hours post inoculation and then incubated with 12 hours of dark and with light at 180 C for 8 days. The experiment was repeated with identical results using independent detached leaf assays. While leaves from plants with over-expression of the StAOS2_CB18 developed lesions similar to the wildtype Bintje potato plants and the empty vector control transgenic, leaves from transgenic plants with StAOS2_CB18_G231T show markedly sed or no lesion pment. ore, this supports that over-expression of the StAOSZ gene allele with the A/C genotype at the 691/692 nt results in sed tolerance to Phytophthora infestans in potato plants.

Similarly, these two gene constructs were also sed in potato plants under the native promoter of the StA052 gene. Potato cultivar Bintje is the parent line to the transgenics while Bintje_pJIHoon is the vector only control transgenic line. The resulting plant lines were also subjected to ion with hthora infestans utilizing the standard detached leaf assay (described herein). Similar to the results obtained for the transgene over-expression plants, while those leaves from plants with over-expression of W0 2014/153178 the _CB18 developed lesions similar to the empty vector l transgenic, leaves from plants with StAOS2_CB1_G231T show ly decreased or no lesion development.

RTDSTM mediated conversion of the A082 alleles To convert AOS2 alleles of interest via the RTDSTM technology, AOS2 GRON is delivered to plant protoplasts (i.e., via PEG mediated uptake of nucleic acids, by electroporation, etc.) carrying a specific change at the targeted nucleic acid residue of interest. For example, to obtain d A/C conversions at the 691/692 position of the A082 gene, respectively, the GRON carries a sequence identical to the upstream and ream of the 691/692 positions of the target AOS2 allele but with AC at the 691/692 positions. The GRON treated cells are developed into calli using established Selection of /calli with desired genotypic alterations Those plants/calli with the d alterations are ed by ion with en challenge (in the potato late blight pathosystem, pathogen challenge will constitute Phytophthora sporangial or zoospore application). Alternatively, the plants/calli with desired alterations are chosen based on non-selection methods such as sequencing of the calli/plant material, e.g., primer-mediated specific amplification of the desired targets to identify those with the desired alterations.

Evaluation and application of multiple rounds of RTDSTM Once plant material with the desired alterations in the A082 gene are identified, genotypic analysis of the A082 gene locus is repeated to completely evaluate the nature of the A082 allele diversity. If “susceptible” or “intermediary” type alleles still exist, those plants/calli are again subjected to RTDS lations to produce desired alterations at the allele. If needed, such iterative rounds of RTDS and selection are repeated as necessary until the desired genotype at the A082 locus/loci is obtained.

Final assessment of ars with desired alterations.

Once calli with the targeted changes are identified, those are rated into plants. Such plants are subjected to evaluations utilizing pathogen assays, JA/OPDA level assessment, protein expression analyses. For these efforts, the wildtype plant are W0 2014/153178 utilized as a control to assess the extent of the intended changes such as higher pathogen resistance, higher JA/OPDA levels in the plants containing the desired conversions.

Example 2: Identification of novel mutations of the A082 gene enhancing AOS2 activity and in planta functional assay.

Generation of novel s of StAOS2 gene To find those amino acids that can enhance the catalytic activity or the stability of the A082 protein that are not observed in nature or those that are not detected by such genotyping analyses (see above), a random mutagenesis effort or a more directed effort at targeted mutagenesis of specific target residues of the A082 protein are undertaken utilizing error prone PCR or Site Directed Mutagenesis (SDM). For site directed mutagenesis, the target sites could constitute sites in the A082 gene identified by the genotyping efforts be above and in Table l (e. g., N76D and T495K), other sites such as those that are predicted to be in the vicinity of the enzyme active site that can have an effect on ate binding or tic ty or others that may affect catalytic activity at a distance.

For such efforts a plasmid DNA of a construct containing a reference gene such as that given by SEQ ID NO: 2 is ed and is subjected to the mutagenesis using established methods (Diversify Random PCR mutagenesis Kit, Clonetech, Mountain view, CA); Error prone refs; QuikChange XL Site-Directed Mutagenesis Kit; Stratagene, San Diego, CA). The mutated clones are selected and subjected to sequence analysis to identify the mutations and those of interest are selected for heterologous n expression utilizing the pQE30 expression system of Qiagen Inc., Valencia, CA (see below).

Alternatively, a library of such mutagenized ucts are cloned into a binary vector and transformed into plant protoplasts and transformants are developed into calli and are rated into plants. The resulting calli are subjected to JA/OPDA levels fication with established s (see e. g., Chebab et al., (2008), PLoS ONE, vol 3: p.el904; Schmelz (2003) Plant Physiol, vol 133: p 295; Engelberth et al. (2003) Anal m, vol. 312, p 242.) and the tolerance of these lines are assessed using a pathogen of interest (e. g. Phytophthora infestans).

Example 3: Identification of novel mutations of the A082 gene enhancing AOS2 activity and complementation analysis in Arabidopsis W0 2014/153178 ] The A082 gene variants that are collected via genotyping analyses or the mutagenesis procedures described above are transformed into the Arabidopsis thaliana aos2 mutant line CS6149 (TAIR, http://www.arabidopsis.org/) and A082 alleles of interest are selected by JA/OPDA levels or by pathogen assays as bed above.
