Transcriptome analysis reveals key genes and secondary metabolites in biosynthesis of iridoids of Gentiana macrophylla Pall . in response to light stimulus

Light is a key factor affecting the synthesis of metabolites in this life, and in recent years, the effect of light-emitting diodes (LEDs) on the production of secondary metabolites in medicinal plants has received extensive attention. However, there are few studies on the effects of light on secondary metabolites by transcriptome and metabolome sequencing, and the regulatory mechanism and regulatory network of light are also unclear.
