Abstract:
Blue mold is the vernacular name of a common postharvest disease of stored apples, pears, and quince that is caused by several common species of Penicillium This study reports the draft genome sequence of Penicillium expansum strain R21, which was isolated from a red delicious apple in 2011 in Pennsylvania.
Insights
