Interpretive Summary: Penicillium expansum (R19), is the most virulent fungus that causes decay of apples during storage (5). In order to understand the genetic mechanism contributing to fungal virulence, spore germination, and mycotoxin production, the genome of the wild-type strain of P. expansum (R19) was sequenced and annotated. Further analysis of the Penicillium genome will help us to identify genes involved in the decaying process of pome fruit during storage. The genetic and genome information will help us in devising specific strategies to prevent or reduce economic losses to agriculture and to the fruit processing industry.

Technical Abstract: Among the species that cause blue mold, isolates of P. expansum are the most prevalent and virulent species causing more than 50 percent of postharvest decay. We report the draft genome sequence of P. expansum (R19) in order to identify fungal virulence factors and to understand the mechanism of infection.
