Pseudomonas Syringae Harpins, Hopptop and Hoppmahpto, and Their Uses.

摘要

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.
