Abstract:

MYB transcription factors are the largest family of transcription factors in plants, and one of their important functions is to regulate anthocyanin synthesis. In order to comprehensively understand the regulation of MYB transcription factors on anthocyanidin synthesis in Solanaceae, this paper summarized the research progress of MYB transcription factors related to anthocyanidin synthesis in seven solanaceous plants, including petunia, potato, tomato, chili, eggplant, tobacco and Lycium chinensis, in terms of gene isolation and cloning, spatio-temporal expression, regulatory mode, etc. By phylogenetic analysis of MYB transcription factors genes related to anthocyanin metabolism pathway in Solanaceae, the author found that activated and inhibited MYB transcription factors in different Solanaceae plants were clustered by functions. The key MYB transcription factor genes regulating anthocyanin synthesis in fruit, namely SlANT1, SmMYB1, StAN1 and StAN2 were preferentially clustered together, and then clustered with StMYBA1, SlAN2 and LrAN2-like. SlAN2-like, SmMYB2, StMYB113LrMYB1 and CaMYB were clustered together. SlAN2 and SlMYB75 of tomato are identical genes with different names; SmMYB1, SmMYB6 and SmMYB113 of eggplant are the same MYB transcription factor genes with different names. In this paper we propose the further research direction of MYB transcription factor genes related to anthocyanin biosynthesis, providing reference for the analysis of tissue-specific regulation mechanism of anthocyanin synthesis in Solanaceae vegetables, the improvement of fruit colors by gene regulation and gene engineering, etc.
