The Cryptochrome CryA Regulates Lipid Droplet Accumulation, Conidiation, and Trap Formation via Responses to Light in Arthrobotrys oligospora.

ABSTRACT: Light is a key environmental factor affecting conidiation in filamentous fungi. The cryptochrome/photolyase CryA, a blue-light receptor, is involved in fungal development. In the present study, a homologous CryA (AoCryA) was identified from the widely occurring nematode-trapping (NT) fungus Arthrobotrys oligospora, and its roles in the mycelial growth and development of A. oligospora were characterized using gene knockout, phenotypic comparison, staining technique, and metabolome analysis. The inactivation of AocryA caused a substantial decrease in spore yields in dark conditions but did not affect spore yields in the wild-type (WT) and ∆AocryA mutant strains in light conditions. Corresponding to the decrease in spore production, the transcription of sporulation
