Patent ID: 7211710

Claim:
A method for selecting a transgenic grapevine or grapevine component having resistance to a grapevine fanleaf disease, said method comprising: (a) transforming a grape plant cell with a grapevine fanleaf virus coat protein nucleic acid molecule or fragment thereof which is expressed in said plant cell; (b) regenerating a transgenic grapevine or grapevine component from the plant cell; and (c) selecting a transgenic grapevine or grapevine component expressing a grapevine fanleaf virus coat protein or coat protein fragment thereof, wherein said coat protein or said coat protein fragment thereof is expressed at a level equal to or less than an optical density of 0.2 at 405 nm as detected by an enzyme-linked immunoassay as compared to a control plant, said selected transgenic grapevine or grapevine component having resistance to said grapevine fanleaf disease.
