PLANT VIRUS-RESISTANT TRANSGENIC PLANTS AND METHOD FOR PRODUCING SAME

摘要

A potyvirus-resistant plant having in its genome one or more DNA fragments expressing transcripts corresponding to a protein or protein fraction of a donor virus, e.g. a protein involved in the formation of a potyvirus replication complex, a protein involved in the transport of a potyvirus between cells, or a protein having a similarity with the cleavage sites of potyvirus viral proteins. A method for producing plant virus-resistant plants comprises inserting vectors from a donor virus complementary cDNA libray into cells or tissue fragments from said plants, and selecting plants displaying plant virus resistance.
