Transcriptional regulation of secondary metabolites biosynthesis in medicinal plants. The pathway-specific functions of transcription factors are illustrated, with activators grouped in red and repressors in blue. Different medicinal plants contain a number of TFs involved in the biosynthesis pathway. An overview of a transcriptional network that is involved in SM biosynthesis in medicinal plants is presented in this review. A large number of positive TFs is identified, but the number of negative TFs is limited. Negative regulatory TFs also play a critical role in establishing the dynamic balance in plant secondary metabolism
