ABSTRACT: 16S rRNA sequencing and Targeted Metabolomics Analyses Reveal Rhizosphere Microbial Diversity and Flavonoids Dynamics in Scutellaria baicalensis Georgi
Project description:Scutellaria baicalensis Georgi, a perennial herb, is an important medicinal plant that possesses broad pharmacological actions and contains flavonoids with good bioactivities such as anti-inflammation, anti-bacteria and anti-tumor. However, little is known on the molecular processes responsible for the medical properties of this species, owing to the absence of genomic resources such as available sequences of key enzyme genes in biosynthetic pathways. In this study, the RNA sequencing data of S. baicalensis were first generated and used for transcriptome analysis.
Project description:This study was designed to measure expressional profile induced by temporal treatment with Scutellaria baicalensis in HepG2 cells. Time-dependent expression of genes by treatment of Scutellaria baicalensis was measured on HepG2 cells. Total RNA was isolated and was subject to single channnel microarray.
Project description:Scutellaria viscidula Bunge (Labiatae), a perennial herb, is an important medicinal plant that possesses broad pharmacological actions. S. viscidula contains flavonoids with good bioactivities (e.g. baicalin, wogonoside, baicalein and wogonin) mainly in its dry root, which is used as alternative to Scutellaria baicalensis in the north of China. Furthermore, S. viscidula also has flavones with interesting diverged structures such as panicolin, viscidulin I, viscidulin II and viscidulin III. Tracing the dynamic process of gene expression will help reveal the mechanism of flavonoid synthesis in S. viscidula, as well as the 4'-deoxyflavone biosynthesis in S. baicalensis. One way is to generate and analyze the expressed sequence tags (ESTs). However, little is known on the transcriptome information of S. viscidula, particularly the key genes involved in flavonoid biosynthesis. In this study, we conducted de novo transcriptome analysis of S. viscidula and obtained 42,310,834 reads and 40,052 unigenes, respectively. We revealed 177 genes relating to flavonoid biosynthesis, where 23 key enzyme encoding genes including CHS, CHI, F3H, PAL and 4CL were annotated. Furthermore, we investigated the dynamic expression of CHS, CHI, F3H, MYB2, and bHLH of stem, root and leaf of S. viscidula in May, July and September. Our results showed that these key genes had important regulatory function and exhibited positive correlation with total flavonoid content in different growth stages of S. viscidula. Collectively, this study provides high-quality transcriptome data of S. viscidula, and further gives significant information for understanding the molecular mechanism of gene expression and active ingredients in Scutellaria plants.
