Proteomic and metabonomic analyses to reveal the underlying molecular mechanism of phenolic acids accumulation in leaves of Salvia miltiorrhiza under UV-B radiation

ABSTRACT: Salvianolic acid is the secondary metabolic products of Salvia miltiorrhiza, and its biosynthesis is induced and regulated by all kinds of abiotic factors. Our results showed that content of salvianolic acid including caftaric acid, salvianolic acid B, roamarinic acid, and salvianolic acid H was increased more than 50 times by UV-B radiation in leaves of Salvia miltiorrhiza. Further proteomic analysis identified 436 significantly proteins which are contributed to salvianolic acid accumulation under UV-B radiation. Among of them, photosynthesis related proteins were decreased, protein processing and phenolic acids synthesis related confirmed and potential key enzymes including cinnamoyl-CoA reductase, rosmarinic acid synthase, phenylalanine ammonia-lyase, were increased in UV-B treated danshen

Comprehensive transcriptome profiling of Salvia miltiorrhiza for discovery of downstream and regulatory genes involved in tanshinone and phenolic acid biosynthesis

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.

RNA sequencing of RAW264.7 with or without Sal-B and LPS addition

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.

Comparison of expression profiles in response to blue, UV-A, and UV-B in the swollen hypocotyls of turnip

Project description:UV-A mediated regulation of anthocyanin biosynthesis was investigated in swollen hypocotyls of the red turnip ‘Tsuda’. The shaded swollen hypocotyls which contained negligible anthocyanin were exposed to artificial light sources including low fluence UV-B, UV-A, blue, red, far-red, red plus UV-A, far-red plus UV-A, and blue plus red. Among these lights, only UV-A induced anthocyanin biosynthesis and co-irradiation of red or far-red with UV-A did not affect the extent of UV-A induced anthocyanin accumulation. The expression of phenylalanine ammonia lyase (PAL; EC 4.3.1.5), chalcone synthase (CHS; EC 2.3.1.74), flavanon 3-hydrocylase (F3H; EC 1.14.11.9), dihydroflavonol 4-reductase (DFR; EC 1.1.1.219) and anthocyanidin synthase (ANS; EC 1.14.11.-) genes were increased with time during a 24 hour exposure of UV-A. In contrast, irradiation of red, blue, UV-B, and a combination of blue with red failed to induce CHS expression. Microarray analysis showed that only a few genes, including chalcone synthase and flavanon 3-hydroxylase were induced significantly by UV-A, while a separate set of many genes was induced by low fluence UV-B. The UV-A specific induction of anthocyanin biosynthesis and the unique gene expression profile upon UV-A irradiation as compared with blue and UV-B demonstrated that the observed induction of anthocyanin biosynthesis in red turnips was mediated by a distinct UV-A specific photoreceptor, but not by phytochromes, UV-A/blue photoreceptors, or UV-B photoreceptors. Keywords: light response

RNA sequencing of HDFs(Human dermal fibroblasts) with or without Sal-B and UVB treatment

Project description:Skin aging is a complex biological process that is influenced by multiple factors, including environmental and genetic factors. Ultraviolet (UV) irradiation can cause short-term sun damage, such as erythema and edema, as well as chronic damage, which accelerates skin aging and produces skin wrinkles and skin laxity. Salvianolic acid B (Sal-B) is the most abundant and bioactive water-soluble extractant from the well-known herbal medicine--Salvia Miltiorrhiza in Chinese traditional medicine. Many studies have found that Sal-B exerts powerful antioxidant and anti-inflammatory effects. Therefore, we speculate that salvianolic acid B may have potential therapeutic value in the aspect of anti-photoaging.

Transcriptional profiling of UV-B response of Populus alba.

Project description:Microarray technology was used to assess transcriptome changes in poplar (Populus alba L.) under a realistic simulation of increased UV-B radiation. Plants were UV-Bbe (UV-B biologically effective radiation) supplemented with a dose of 6 kJ/m2/day for 12 hours per day and allowed to recover during the night. Poplar plants were UV-B treated using a refined controlled environment able to guarantee a realistic simulation of natural conditions, especially for light parameters such as presence of background UV-B radiation for control plants and balanced PAR/UV-A/UV-B ratio. A time course experiment was planned to look both at the rapid and delayed response of poplar to UVB; two time points after 3 h (T3h) and 30 h (6th hour of the third day of treatment, T30h) were considered. 4 independent biological replicates were analysed for each time point. Competitive hybridisations were carried out using the PICME 28K microarray. Keywords: Time course experiment, stress response

Transcriptional response to UV treatment in several Arabidopsis thaliana accessions

Project description:UV radiation is a ubiquitous component of solar radiation that affects plant growth and development. Analysis of natural variation in response to UV radiation revealed significant differences among natural accessions of Arabidopsis thaliana. However, the genetic basis of this is to a large extent unknown. Here, we analyzed the response of Arabidopsis accessions to UV radiation stress by performing RNA-sequencing of three UV sensitive and three UV resistant accessions. The genome-wide transcriptional analysis revealed a large number of genes significantly up- or down-regulated only in sensitive or only in resistant accessions, respectively. Mutant analysis of few selected candidate genes suggested by the RNA-sequencing results indicate a connection between UV radiation stress and plant-pathogen-like defense responses.
