Identification of bHLHs based on transcriptome and molecular mechanism of transcription factor CabHLH118 regulating anthocyanin biosynthesis in chili (Capsicum annuum L.)fruit.
Yeast one-hybrid and dual-luciferase assay demonstrated that CabHLH118 can bind to the upstream promoter of CaF3'H and promote anthocyanin formation, and CabHLH118 may respond to blue light to enhance anthocyanin biosynthesis, although the underlying mechanism requires further verification.
