Project description:We determined genes that directly or indirectly regulated by CatR (or PerR), and hydrogen peroxide regulon in Streptomyces coelicolor.
Project description:We identified genome-wide binding regions of NdgR in Streptomyces coelicolor using chromatin immunoprecipitation sequencing (ChIP-seq). We constructed 6×myc-tagged NdgR strain using homologous recombination with myc-tagging vector. Analysis of the sequencing data aligned to Streptomyces coelicolor genome database (NC_003888).
Project description:We determined Streptomyces coelicolor genes that are directly regulated by WblC (or WhiB7), an actinobacterial transcription factor that activates expression of intrinsic resistance in response to translation-inhibitory antibiotic stress. Identification of differentially expressed genes in wblC mutant by RNA-seq and WblC binding sites in wild type by ChIP-seq identified more than 300 genes as WblC regulon. This series encompasses the RNA-seq data of our study.

Project description:Global regulation by the Streptomyces coelicolor atypical MerR-like transcription factor BldC. BldC is a transcriptional regulator essential for morphological development and antibiotic production in Streptomyces coelicolor. Here we identify the BldC regulon by means of chromatin immunoprecipitation (ChIP) microarray analysis. The BldC regulon encompasses at least 201 transcriptional units, which include many genes that play key roles in Streptomyces development (e.g., bldC itself, bldB, bldM, whiB, whiD, whiI, sigF, smeA-sffA, hupS), antibiotic production (e.g., afsK) and stress response (e.g., clpB, nsrR, sigE, sigF). All BldC-binding sites identified by ChIP-chip are present in the promoters of the target genes. In vitro DNA-binding experiments show that BldC is capable of binding DNA specifically in the absence of other proteins and suggest that BldC is a minor-groove DNA-binding protein. The regulon of BldC partially overlaps with that of the pleiotropic regulator BldD. BldC and BldD bind to distinct sites in the promoter region of smeA, where they simultaneously repress its transcription.
Project description:To identify unique gene expression in cAMP supplemented Streptomyces coelicolor M1146 strain. The genes with different gene expression might be key genes to understand the effects of cAMP supplementation on the transcriptome of Streptomyces coelicolor M1146.
Project description:To identify unique gene expression in cAMP supplemented Streptomyces coelicolor M145 strain. The genes with different gene expression might be key genes to understand the effects of cAMP supplementation on the transcriptome of Streptomyces coelicolor M145.
Project description:In this work, we demonstrate that the addition of the small molecule elicitor ARC2 to Streptomyces coelicolor cultures results in global changes in gene expression including many secondary metabolic genes. A profile of the Streptomyces coelicolor transcriptome in the absence and presence of ARC2 was performed by RNA-seq. Total RNA was extracted after 10 hours of treatment with either the DMSO solvent control or the ARC2 small molecule elicitor. A V2 rapid run mode with paired-end 2x75 bp reads on the Illumina HiSeq platform was performed for RNA sequencing.
