Abstract

The present invention relates to isolated nucleic acid mol ecules encoding a type III—secreted bacterial protein capable of modifying a cell death pathway in a plant cell. One aspect of the present invention involves an isolated nucleic acid molecule having a nucleotide sequence that encodes the HopPtol)2 protein of Pseudomonas syringae pv. syringae DC 3000. Expression vectors, host cells, and transgenic plants which include the DNA molecules of the present invention are also disclosed. The nucleic acid mol ecules of the present invention can be used to impart disease resistance to a plant and to make a plant hypersusceptible to colonization by nonpathogenic bacteria.
