PLANT PROTECTION FOR VIRUS INFECTION

摘要

A process for producing genetically transformed plants which are resistant to infection by a plant virus, comprises the steps of: (a) inserting into the genome of a plant cell a recombinant, double-stranded DNA molecule comprising (i) a promoter which functions in plant cells to cause the production of RNA sequences of said plant virus; (ii) a DNA sequence that corresponds to an RNA sequence of said plant virus. (iii) 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; (b) obtaining transformed plant cells; and (c) regenerating from the transformed plant cells genetically transformed plants which have increased resistance to infection by said plant virus. o
