Project description:Tanshinones and phenolic acids are crucial bioactive compounds biosynthesized in Salvia miltiorrhiza. Methyl jasmonate (MeJA) is an effective elicitor to enhance the production of phenolic acids and tanshinones simultaneously, while yeast extract (YE) is used as a biotic elicitor that only induce tanshinones accumulation. However, little was known about the different molecular mechanism. To identify the downstream and regulatory genes involved in tanshinone and phenolic acid biosynthesis, we conducted comparative transcriptome profiling of S. miltiorrhiza hairy roots treated with either MeJA or YE.Total 55588 unigenes were assembled from about 1.72 billion clean reads, of which 42458 unigenes (76.4%) were successfully annotated. The expression patterns of 19 selected genes in the significantly upregulated unigenes were verified by quantitative real-time PCR. The candidate downstream genes and other cytochrome P450s involved in the late steps of tanshinone and phenolic acid biosynthesis pathways were screened from the RNA-seq dataset based on co-expression pattern analysis with specific biosynthetic genes. Additionally, 375 transcription factors were identified to exhibit a significant up-regulated expression pattern in response to induction. This study can provide us a valuable gene resource for elucidating the molecular mechanism of tanshinones and phenolic acids biosynthesis in hairy roots of S.miltiorrhiza.

Project description:Autologous fat grafting (AFG), although an appealing approach to repair soft tissue defects, has various complications. Excessive inflammation at the transplant site is one of the main reasons for the poor effect of fat transplantation and occurrence of complications. Our previous study proved that Salvia miltiorrhiza can enhance fat graft survival. Salvianolic acid B (Sal-B) is the most abundant and bioactive water-soluble compound in Salvia miltiorrhiza and has anti-inflammatory effects on other diseases. Therefore, we hypothesized that salvianolic acid B could improve the effect of fat grafts by inhibiting inflammation.
