DNA encoding Erwinia amylovora hypersensitive response elicitor and its use

摘要

The present invention is directed to an isolated DNA molecule from Erwinia amylovora that encodes a protein or polypeptide which elicits a hyersensitive response in plants. This isolated DNA molecule can used to impart disease resistance to plants, to enhance plant growth, and/or to control insects on plants. Plants or plant seeds transformed with a DNA molecule encoding a hypersensitive response elicitor protein or polypeptide can be provided and the transgenic plants or plants resulting from the transgenic plant seeds are grown under conditions effective to impart disease resistance, to enhance plant growth, and/or to control insects on plants or plants grown from the plant seeds.
