This isolated protein or polypeptide and the isolated DNA molecule can 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.Type: GrantFiled: July 22, 1998Date of Patent: May 8, 2001Assignee: Cornell Research Foundation, Inc.Inventors: Adam J.
