转录因子MYB在光诱导的苯丙烷次生代谢中的作用

Roles of MYB in Light-Induced Accumulation of Phenylpropanoids Metabolites

MYB转录因子是真核生物转录因子中最大的一个家族之一,在植物生命进程中发挥着重要作用,包括参与植物初生和次生代谢产物的合成、细胞形态结构以及调控植物对生物和非生物胁迫的应答等。文章综述了MYB转录因子在苯丙烷类次生代谢途径中的重要作用,着重介绍了MYB转录因子在光诱导的苯丙烷代谢产物积累中的作用,为MYB转录因子功能研究提供参考。

MYB transcription factors belong to one of the largest families of eukaryotic transcription factors. Most of the MYB members have been reported to be responsible for the primaDT and secondary metabolism by responding to endogenous or exogenous signals. As one of the large group of plant secondary metabolites, phenylpropanoids play muhiple physiological roles like modulating the development and morphological construction of organ and tissue,improving the resistant ability towards biotic and abiotic stresses from the environment. From the point of application view ,phenylpropanoids could be used as therapeutic compounds at clinical like rosmarinic acids and salvianolic acid B and food additives and flavors like flavonoids and anthocyanins. Here we gave a brief review of the important roles of MYB in the phenylpropanoid metabolism especially in the light-induced accumulation of such natural compounds.
