The photoinduced β-carotene synthesis in <i>Blakeslea trispora</i> is dependent on WC-2A.

ABSTRACT: β-Carotene, a high value-added natural pigment, is currently produced industrially in Blakeslea trispora. Although photoinduced carotenoid synthesis has been identified in some filamentous fungi, there are still relatively few studies focusing on B. trispora and its potential mechanisms. In this study, an integrated strategy-including correlation analysis of gene expression, bioinformatics analysis, protein interaction, and RNA interference-was adopted to elucidate photoinduced β-carotene synthesis in B. trispora. Light wavelength, intensity, and irradiation duration stimulated the transcription of photoreceptors [btwc-1 (a, b, c) and btwc-2 (a, b, c, d)] and carotenoid structural genes (carB and carRA). The transcription of ph
