Abstract: Disclosed herein are methods for identifying amino acid residues of NLRs that are likely involved in pathogen immunity. Also disclosed are methods for modifying plant immunity which comprise modifying (e.g., substituting, deleting, or adding an amino acid before or after) one or more of the amino acid residues that have been identified as being likely involved in pathogen immunity.

Abstract: Provided herein is a non-Nicotiana transgenic plant comprising an exogenous polynucleotide encoding Nicotiana benthamiana Roq1 or a variant thereof. These plants have enhanced resistance to at least one species of Xanthomonas, Pseudomonas, Ralstonia, and/or another pathogen containing a homolog of XopQ whose recognition is mediated by Roq1.

Abstract: The invention provides plants and seeds with enhanced resistance to plant disease caused by plant pathogens, particularly bacterial plant pathogens, and methods for producing such plants and seeds. The plants and seeds comprise mutated alleles of the Bs5 gene and/or Bs5-like gene that are capable of conferring to plants comprising the alleles enhanced resistance to plant pathogens. The present invention further provides methods of using the plants and seeds in agricultural production to limit plant diseases caused by plant pathogens.

Abstract: The invention provides seed and plants of tomato comprising transgenic event Bs2-X5 and progeny thereof comprising this transgenic event and uses of such seeds and plants in the production of tomato fruit. The invention thus relates to non-hybrid and hybrid plants, seeds, and tissue cultures of tomato comprising transgenic event Bs2-X5, and to methods for producing a tomato plant produced by crossing such plants with themselves or with another tomato plant, such as a plant of another genotype. The invention further relates to seeds and plants produced by such crossing. The invention further relates to parts of such plants, including the fruit and gametes of such plants.

Abstract: Methods and compositions for making citrus plants with enhanced resistance to Asiatic citrus canker (ACC) and other forms of citrus canker caused by Xanthomonas are provided. The methods involve transforming citrus plant cells with polynucleotide constructs comprising a promoter operably linked to nucleotide sequence that encodes a protein that is capable of triggering cell death in a citrus plant. The promoters of the invention are inducible by one or more Xanthomonas strains that cause citrus canker. Isolated nucleic acid molecules and expression cassettes comprising such polynucleotide constructs and promoters are further provided. Citrus plants with enhanced resistance to citrus canker are also provided.

Abstract: Disclosed is substantially pure DNA encoding an Arabidopsis thaliana Rps2 polypeptide, substantially pure Rps2 polyneptide; and methods of using such DNA to express the Rps2 polypeptide in plant cells and whole plants to provide, in transgenic plants, disease resistance to pathogens. Also disclosed are conserved regions characteristic of the RPS family and primers and probes for the identification and isolation of additional RPS disease-resistance genes.

Abstract: The invention relates to a method of identifying a plant disease-resistance gene that includes the steps of (a) providing a plant tissue sample; (b)introducing by biolistic transformation into the plant tissue sample a candidate plant disease-resistance gene; (c) expressing the candidate plant disease-resistance gene within the plant tissue sample; and (d) determining whether the plant tissue sample exhibits a disease-resistance response, whereby a response identifies a plant disease-resistance gene.
