 In this study, researchers identified 164 barley WD40 genes and found that three of them could form a MYBBHLHWD, MBW, complex and regulate the expression of the anthocyanin synthesis-related structural gene HVDFR. This provides a theoretical basis for further study of the mechanism of how these genes interact in the MBW complex related to anthocyanin synthesis in Chinka.
