, the cause of scab disease of Asian pears, is a host-specific, biotrophic fungus. It is restricted to Asia and is regarded as a quarantine threat outside this region. European pear displays nonhost resistance (NHR) to and Asian pears are nonhosts of (the cause of European pear scab disease). The host specificity of these two fungi is likely governed by differences in their effector arsenals, with a subset hypothesized to activate NHR. The pathosystem provides an opportunity to dissect the underlying genetics of nonhost interactions in this potentially more durable form of resistance. The genome will enable comparisons to other spp. genomes to identify effectors that potentially activate NHR in the pear scab pathosystem.
亚洲梨痂病的病原菌是一种专性寄生真菌，仅局限于亚洲，在该地区以外被视为检疫性威胁。欧洲梨对梨痂病菌表现出非寄主抗性（NHR），而亚洲梨则是梨痂病菌的非寄主（欧洲梨痂病的病原菌）。这两种真菌的寄主专化性可能是由其效应子库的差异所决定的，据推测其中一部分效应子能够激活非寄主抗性。这个病原菌体系为剖析梨痂病潜在更持久抗性形式的非寄主互作的遗传基础提供了机会。梨痂病菌基因组将使我们能够与其他 spp. 基因组进行比较，以鉴定在梨痂病病原菌体系中可能激活非寄主抗性的效应子。
