Abstract:
1. A method for conferring pest resistance to a plant comprising a step of selecting a first pathogenicity gene, a step of selecting a second pathogenicity gene, a step of transforming a host plant cell with a heterologous polynucleotide, and a step of regenerating the plant from the host plant cell, said heterologous polynucleotide comprising: (a) a first antisense sequence having at least 80% homology to the first pest pathogenicity gene; (b) a second antisense sequence having at least 80% homology to the second pest pathogenicity gene; (c) a first sense sequence substantially complementary to said first antisense sequence; and (d) a second sense sequence substantially complementary to said second antisense sequence; wherein: whereby the plant is resistant to a first fungus expressing at least one gene having substantial homology to the first antisense sequence.
