Abstract: Anthocyanin is one of the key substances in the plant coloration,which can not only endue plants with rich colors,but also have a wide range of biological functions,such as anti-oxidation,anti-ultraviolet,resistance to diseases and insect pests. The plant anthocyanin biosynthesis pathway is completed while synergizing by a series of structural and regulative genes. The structural genes are regulated and expressed by MYB,bHLH and WD40 transcription factors and the MBW complexes composed of them. This paper reviews the recent research progresses in functions of MYB,bHLH and WD40 transcription factors and MBW complexes in anthocyanin synthesis in plants,and summarizes various biological processes and regulatory networks in anthocyanin synthesis.

Key words: anthocyanin, bHLH, MYB, MBW complexes, WD40
