Whole-genome comparisons of Penicillium spp. reveals secondary metabolic gene clusters and candidate genes associated with fungal aggressiveness during apple fruit decay.

Blue mold is a postharvest rot of pomaceous fruits caused by Penicillium expansum and a number of other Penicillium species. The genome of the highly aggressive P. expansum strain R19 was re-sequenced and analyzed together with the genome of the less aggressive P. solitum strain RS1. Whole genome scale similarities and differences were examined. A phylogenetic analysis of P. expansum, P. solitum, and several closely related Penicillium species revealed that the two pathogens isolated from decayed apple with blue mold symptoms are not each other’s closest relatives. Among a total of 10,560 and 10,672 protein coding sequences respectively, a comparative genomics…
