Abstract:

The research progress on the mechanisms of flower color formation,flower color genesis,anthocyanin glycoside biosynthesis,and transcriptional regulation were analyzed and summarized in Lagerstroemia indica. The results showed that anthocyanin glycosides were the main color-presenting substances in plants. Their types,anabolic pathways,and other factors have an important impact on flower color formation. The preliminary analysis and functional identification of the components of anthocyanidin,and related structural genes and transcription factors in anthocyanin synthesis pathway of L. indica found that there is not a full understanding of the formation of flower color in L. indica. Therefore,there is a need to analyze the molecular mechanism and regulatory process of metabolism in L. indica,and then to analyze the reasons for the presentation of flower color in L. indica at the microscopic level,so as to provide a theoretical basis for new superior color cultivars.

Key words: Lagerstroemia indica, anthocyanin glycoside biosynthesis, mechanism of color presentation
