US 2004/0006789 A1 · Pseudomonas syringae harpins, HopPtoP and HopPmaHpto, and their uses

Abstract

The present invention is directed to isolated proteins or polypeptides which elicit a hypersensitive response in plants, as well as isolated DNA molecules which encode the hypersensitive response eliciting proteins or polypeptides. These isolated proteins or polypeptides and the isolated DNA molecules can be used to impart disease resistance, stress resistance, and enhanced growth to plants or plants grown from treated seeds, to control insects on plants or plants grown from treated plant seeds, to impart post-harvest disease or desiccation resistance in fruits or vegetables, to impart enhanced longevity of fruit or vegetable ripeness, to impart desiccation resistance to cuttings of ornamental plants, and/or promote early flowering of ornamental plants, either by topical application of the proteins or polypeptides or transgenic expression in recombinant plants or plant seeds.

Dependent claims

An isolated DNA molecule that encodes a hypersensitive response eliciting protein or polypeptide and is selected from the group consisting of

(a) a DNA molecule comprising the nucleotide sequence of SEQ ID NO:
1 or SEQ ID NO:
3,
(b) a DNA molecule encoding a protein or polypeptide comprising the amino acid of SEQ ID NO:
2 or SEQ ID NO:
4, and
(c) a DNA molecule that hybridizes to the complement of SEQ ID NO:
1 or SEQ ID NO:
3 under hybridization conditions including a hybridization medium comprising 5×SSC buffer at a temperature of at least about 42° C. for about 18 hours;
or
an isolated DNA molecule that is complementary to at least one of DNA molecules (a), (b), or (c).
