Fig. 1 in SmbHLH3 acts as a transcription repressor for both phenolic acids and tanshinone biosynthesis in Salvia miltiorrhiza hairy roots

Fig. 1. The chemical structures of three water-soluble phenolic acids (CA, caffeic acid; RA, rosemarinic acid; SAB, salvianolic acid B) (A) and four lipid-soluble tanshinone (T-I, tanshinone I; T-IIA, tanshinone IIA; CT, cryptotanshinone; DT-I, dihydrotanshinone I) (B) studied in this article.
