摘要： Background The objectives of this study were to reveal the anthocyanin biosynthesis metabolic pathway in white and purple flowers ofSalvia miltiorrhizausing metabolomics and transcriptomics, to identify different anthocyanin metabolites, and to analyze the differentially expressed genes involved in anthocyanin biosynthesis. Results We analyzed the metabolomics and transcriptomics data ofS. miltiorrhizaflowers. A total of 1994 differentially expressed genes and 84 flavonoid metabolites were identified between the white and purple flowers ofS. miltiorrhiza. Integrated analysis of transcriptomics and metabolomics showed that cyanidin 3,5-O-diglucoside, malvidin 3,5-diglucoside, and cyanidin 3-O-galactoside were mainly responsible for the purple flower color ofS. miltiorrhiza.A total of 100 unigenes encoding 10 enzymes were identified as candidate genes involved in anthocyanin biosynthesis inS. miltiorrhizaflowers. Low expression of theANSgene decreased the anthocyanin content but enhanced the accumulation of flavonoids inS. miltiorrhizaflowers. Conclusions Our results provide valuable information on the anthocyanin metabolites and the candidate genes involved in the anthocyanin biosynthesis pathways inS. miltiorrhiza.
