Title: Research progress on the molecular regulation mechanism of anthocyanin biosynthesis pathway
Abstract: Anthocyanin is a natural water-soluble pigment which widely exists in plants. Flower color is determined by the inherited characteristics and regulatory mechanism of anthocyanin biosynthesis pathway. In recent years,the anthocyanin biosynthesis pathway has been revealed clearly. The structural genes in anthocyanin biosynthesis pathway are mainly regulated by some transcription factors at transcription levels. Recent researches show that some important transcription factors that regulate the structure genes in anthocyanins metabolic pathway mainly include WD40 repeat proteins,b HLH proteins and R2R3 MYB proteins. The combinations and interactions between these transcription factors determine the expression of structure genes. In this review,the molecular mechanism of anthocyanin biosynthesis is discussed. Transcription factors form trimer complex and combine with the promoter of structural genes to regulate its expression. We also summarize the application of the molecular mechanisms in flower color modification and anthocyanin content improvement.
