Moreover, many secondary metabolites have pharmaceu- tical efficacy for a wide range of diseases (cancer, malaria, etc.). Controlled transcription of biosynthetic genes is one of the major mechanisms regulating sec- ondary metabolism in plants. Several transcription factor families such as MYC, MYB, WRKY and AP2/ERF have been found to be involved in the regulation of secondary metabolism in different medicinal plants. In addition, the biosynthesis and proper accumulation of secondary metabolites are also induced by signaling molecule jasmonic acid (JA). This review provides an insight into JA signaling pathway and JA-mediated transcriptional regu- lation of secondary metabolism (vinblastine, nicotine, artemisinin, taxol and ginsenoside) in a range of medicinal plant species.展开更多
