Whole Genome Sequence Resource of the Asian Pear Scab Pathogen .

, 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.
