Research progress of jasmonate-responsive transcription factors in regulating plant secondary metabolism

Abstract

Jasmonates, as a plant endogenous hormone, can induce the biosynthesis of terpenoids, alkaloids and flavonoids and other medicinal active ingredients, and play an important role in the plant secondary metabolic process. The tanscription factors can activate the expression of multiple genes in the biosynthesis of plant secondary metabolites by binding the cis-elements of the target genes. Then, it effectively activates or inhibits the activities of the enzymes on the biosynthesis of plant secondary metabolites, further regulate specific biosynthesis and accumulation of secondary metabolites. Here, We review recent major progresses regarding the regulation of secondary metabolites by JAs-responsive transcription factors (TFs) (including AP2/ERFs, bHLH, MYB and WRKY). That provides suggestions for further analysis of jasmonic acid signaling pathway and regulation of secondary metabolism, and explores the potential value of transcription factor in improving the medicinal active ingredients.
