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

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.
