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

The NDR1 gene of has been cloned and sequenced. NDR1 is necessary for plant defense mediated by numerous disease resistance gene products. Expression of NDR1 in transgenic plants confers resistance to a broad variety of plant pathogens.

Compositions and methods for plant pathogen resistance

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

The NDR1 gene of Arabidopsis thaliana has been cloned and sequenced. NDR1 is necessary for plant defense mediated by numerous disease resistance gene m products. Expression of NDR1 in transgenic plants confers resistance to a broad variety of plant pathogens.

Composition and method for plant pathogen resistance

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.
