Interpretive Summary:

Technical Abstract: Penicillium species cause postharvest blue mold decay of apples and pears in the United States and in many countries worldwide. This genus is responsible for severe economic losses and produces an array of mycotoxins that contaminate processed apple products. Among the species that cause blue mold, P. expansum is the most prevalent, causing more than 50 percent of the postharvest decay during storage. P. solitum is less virulent compared with P. expansum but causes decay. To analyze the genetic mechanisms contributing to pathogen virulence, spore germination, and mycotoxin production, the whole genome of P. solitum (RS1 isolate) was sequenced. After assembly of the raw sequences, the genome is estimated to contain 31 million base pairs. The genome size is similar to that previously reported for P. chrysogenum. These sequences have been deposited in the NCBI GenBank database. The sequence information will provide the scientific community a valuable resource for predicting putative genes that could contribute to fungal virulence, spore germination, and toxin production. Further studies to determine gene function in the fungus will help in devising specific strategies for control of blue mold decay on apples and pears during long term storage.
