Avirulence genes of Magnaporthe oryzae are a pathogen defense arsenal shaped by cognate rice resistance genes in the field

Summary We examined the frequency of and variation in eight avirulence ( AVR ) genes from 840 Magnaporthe oryzae field isolates collected from the Southern United States relative to rice resistance ( R ) genes deployed from 1959 to 2017. Little coding or noncoding variation was d...
