Genetic sequences of plant pathogen avirulence genes and uses therefor

摘要

The invention provides an isolated nucleic acid molecule comprising a sequence of nucleotides encoding or complementary to a sequence of nucleotides encoding an avirulence product of a plant rust fungus, and its use in transformation of a plant to induce a disease resistance response in the plant, optionally by co-expression with a corresponding disease resistance gene in the plant. The invention also provides a method of identifying a ucleic acid sequence which encodes an avirulence product of a plant rust fungus.
