调控植物类黄酮生物合成的转录因子研究进展

Advance in transcriptional factors regulating flavonoid biosynthesis

植物色泽表型的差异取决于体内色素种类、含量、色素分布及表皮细胞形态等多方面的内在因素。笔者从调控类黄酮色素合成途径的转录因子入手,结合国外该研究领域中取得的成果,对调控类黄酮生物合成的转录因子的类型、表达特性、功能和进化研究进行总结和分析,探讨其在花色选育中的应用前景。

Variation of plant color was determined by many inner factors,including pigments and their contents,pigments distribution,and morphology of flower epidemical cell.We collected many documents from different perspectives to illustrate the advance in the transcriptional factors（TFS） regulated on flavonoid biosynthesis.Based on related study,there were three types of transcriptional factors involving in regulation process.Myb,bHLH and WD40 TFs in regulating the processes of plant anthocyanidin synthesis were analyzed for their chemical structures and other relevant functions.The homologous genes cloned so far were listed in this review.Moreover,their co-expression traits involved in same or different types of TFS were summarized for the main genes studied in model plants.Many TFS were found to regulate both anthocyanin biosynthesis and trichome development and differentiation,such as CPC and TTG1.Evolutional traits of TFS were summarized.Their applications for plant color breeding and selection were also discussed.
