USE OF HYPERSENSITIVE RESPONSE ELICITOR FROM GRAM POSITIVE BACTERIA.

摘要

The present invention is directed to the use of a protein or polypeptide from Gram positive bacteria, such as Clavibacter michiganensis subsp. sepedonicus, which elicits a hypersensitive response in plants. This protein or polypeptide can be used to impart disease resistance to plants, to enhance plant growth, and/or to control insects on plants. This can be achieved by applying the hypersensitive response elicitor protein or polypeptide in a non-infectious form to plants or plant seeds 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.
