avirulence gene

avirulence gene
Abbreviation: avr gene
Many plants contain R genes, which confer simply-inherited resistance to a specific pathogen race. The plants are able to recognize the presence of the pathogen by an interaction between their R gene and the matching pathogen's avirulence gene. Successful recognition triggers a cascade of further genes, often leading to a hypersensitive response.
