Abstract

Transcriptional analysis showed a dramatic increase in the expression of polyketide synthase gene 1 (pks1) in mature and post-harvest fruiting bodies of Grifola frondosa. Therefore, PKS1 may be closely associated with melanin biosynthesis in this polypore mushroom, and melanin synthesis via the 1,8-dihydroxynaphthalene pathway might play a role in fruiting body spoilage.
