Protection of plants against viral infection

摘要

The invention involves recombinant, double-stranded DNA that contains a promoter which functions in plant cells to cause the production of RNA sequences of a plant virus, a DNA sequence that causes the production of an RNA sequence encoding the coat protein of said plant virus, and a 3' non-translated region which functions in plant cells to cause the addition of polyadenylated nucleotides to the 3' end of said RNA sequence; which double-stranded DNA can be used in a method for genetically transforming plants to produce genetically transformed plant cells and plants that are resistant to virus infection.
