Avirulence gene. A subset of genes in a pathogen encoding effector proteins: A gene the presence of which results in incompatibility when the host possesses the corresponding resistance (R) gene (according to the gene-for-gene hypothesis). An Avr gene can thus encode a specific elicitor. The recessive allele is written avr, though vir is also used in epidemiological literature.
