HYPERSENSITIVE RESPONSE ELICITOR FROM ERWINIA AMYLOVORA, ITS USE, AND ENCODING GENE

摘要

The present invention is directed to an isolated protein or polypeptide whichelicits a hypersensitive response in plants as well as an isolated DNAmolecule which encodes the hypersensitive response eliciting protein orpolypeptide. This isolated protein or polypeptide and the isolated DNAmolecule can be used to impart disease resistance to plants, to enhance plantgrowth, and/or to control insects on plants. This can be achieved by applyingthe hypersensitive response elicitor protein or polypeptide in a non-infectious form to plants or plant seeds under conditions effective to impartdisease resistance, to enhance plant growth, and/or to control insects onplants or plants grown from the plant seeds. Alternatively, transgenic plantsor plant seeds transformed with a DNA molecule encoding a hypersensitiveresponse elicitor protein or polypeptide can be provided and the transgenicplants or plants resulting from the transgenic plant seeds are grown underconditions effective to impart disease resistance, to enhance plant growth,and/or to control insects on plants or plants grown from the plant seeds.
