Provided herein is a plant comprising an exogenous polynucleotide encoding a JIM2 polypeptide. In some embodiments, the plants have enhanced resistance to at least one species of

ZAR1 and JIM2 mediate resistance against plant pathogens containing YopJ-family effectors

Provided herein is a non-transgenic plant comprising an exogenous polynucleotide encodingRoq1 or a variant thereof. These plants have enhanced resistance to at least one species of, and/or another pathogen containing a homolog of XopQ whose recognition is mediated by Roq1.

ROQ1 provides resistance to both xanthomonas and pseudomonas in plants

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.

Tomato plants comprising transgenic event Bs2-X5

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.

Methods of identifying plant disease-resistance genes

Bs2 resistance proteins that confer resistance to the plant pathogen are disclosed. These proteins may be expressed in transgenic plants that are otherwise susceptible to infection by this bacterium in order to enhance resistance.

Bs2 resistance protein

Nucleic acid molecules (cDNAs and genes) that confer resistance to the plant pathogen,are disclosed. These molecules may be introduced into plants that are otherwise susceptible to infection by this bacterium in order to enhance resistance.

BS2 resistance gene

Disclosed is substantially pure DNA encoding an,Rps2 polypeptide; substantially pure Rps2 polypeptide; 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.

RPS gene family, primers, probes, and detection methods

Disclosed is a new plant resistance gene family, the members of which encode plant resistance polypeptides having P-loop and LRR structural motifs. Also disclosed are substantially pure plant DNAs encoding such polypeptides. The invention further involves transgenic plants and transformed host cells that express these DNAs and exhibit enhanced disease resistance to plant pathogens.

Plant resistance gene family encoding resistance polypeptides having

Disclosed is substantially pure DNA encoding an Arabidopsis thaliana Rps2 polypeptide; substantially pure Rps2 polypeptide; 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.

A process for identifying a plant having disease tolerance comprising administering to a plant an inhibitory amount of ethylene and screening for ethylene insensitivity, thereby identifying a disease tolerant plant, is described. Plants identified by the foregoing process are also described.

Method of identifying plant pathogen tolerance

DNA sequences encoding for ice nucleation activity are isolated and introduced into unicellular hosts. The modified hosts demonstrate ice nucleation activity analogous to the DNA source host. The cellular products find use in inhibiting supercooling.
