Abstract
The present invention relates to an isolated protein or polypeptide corresponding to a coat protein or polypeptide of a grapevine leafroll virus. The encoding DNA molecule either alone in isolated form or in an expression system, a host cell, or a transgenic grape plant is also disclosed. Another aspect of the present invention relates to a method of imparting grapevine leafroll resistance to grape plants by transforming them with the DNA molecule of the present invention. A method for imparting tristeza virus resistance in citrus plants using the DNA molecule of the present invention is also disclosed.
