Based on the theory of Q-marker, the hairy root of Salvia miltiorrhiza and S. miltiorrhiza in many provinces were studied. The relative expressions of SmCPS, SmKSL and CYP76AH1 genes in hairy roots were detected by real-time fluorescence quantitative PCR and the contents of tanshinoneⅡ_A,

RNA interference targeting CYP76AH1 in hairy roots of Salvia miltiorrhiza reveals its key role in the biosynthetic pathway of tanshinones.

Plant cytochrome P450s (CYPs) are well known as the largest family of enzymes that contribute to both primary metabolism and the chemical diversity of plant secondary metabolites. It is important to elucidate the in vivo role of CYPs in secondary metabolism, in order to apply them in the production

Protein tyrosine phosphatase 1B (PTP1B) is a negative regulator that plays an important role in many signaling pathways, especially those associated with insulin resistance. In this study, we investigated the anti-diabetic potential of 12 natural tanshinones isolated from Salvia miltiorrhiza (S.

CYP76AH1 catalyzes turnover of miltiradiene in tanshinones biosynthesis and enables heterologous production of ferruginol in yeasts.
