<p>Provided is a method for conferring fungal resistance to a plant comprising expressing in the plant: (a) a first antisense sequence having at least about 80% homology to a stretch of at least about 20 nucleotides of a first fungal pathogenicity gene; (b) a second antisense sequence having at least about 80% homology to a stretch of at least about 20 nucleotides of a second fungal 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 a transcript of the first antisense sequence and a transcript of the first sense sequence are capable of hybridizing to form a double stranded region; wherein a transcript of the second antisense sequence and a transcript of the second sense sequence are capable of hybridizing to form a double-stranded region; whereby the plant is resistant to a fungus expressing a fungal pathogenicity gene having at least about 80% homology to at least one of said first antisense sequence and said second antisense sequence.</p> |
