Gibberellin-Induced Transcription Factor SmMYB71 Negatively Regulates Salvianolic Acid Biosynthesis in Salvia miltiorrhiza.

ABSTRACT: Salvia miltiorrhiza, the valuable traditional Chinese medicinal plant, has been used in clinics for thousands of years. The water-soluble salvianolic acid compounds are bioactive substances used in treating many diseases. Gibberellins (GAs) are growth-promoting phytohormones that regulate plant growth and development. Previous studies have demonstrated that GAs can promote salvianolic acid accumulation in S. miltiorrhiza; however, the underlying mechanism requires further investigation. Here, we identified a GA-induced R2R3MYB transcription factor (TF), SmMYB71, from a transcriptome library of GA-treated S. miltiorrhiza. SmMYB71 was highly expressed in the root of S. miltiorrhiza and localized to the nucleus. SmMYB71-knockout hairy roots sho
