Salvia miltiorrhiza Bunge, a well-known traditional Chinese herbal medicine, has been served as not only medicine for human ailments, but also health care products. As one of major bioactive ingredients, tanshinones are widely used to treat cardiovascular and cerebrovascular diseases, and also possess different pharmacological activities including anti-tumor, anti-inflammatory, anti-fibrotic and others. However, the content of tanshinones is relatively low in S. miltiorrhiza plants. Recently, multiple biotechnological strategies have been applied to improve tanshinone production. In this review, advances in bioactivities, biosynthesis pathway and regulation, transcriptional regulatory network, epigenetic modification and synthetic biology are summarized, and future perspectives are discussed, which will help develop high-quality S. miltiorrhiza resources.
Keywords: Salvia miltiorrhiza; biosynthesis; biotechnology; regulation; tanshinones.
