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:This study compared the genome of Streptomyces rimosus rimosus against that of Streptomyces coelicolor. It also compared 4 strains with changes in oxytetracycline production and derived from G7, the type strain, against G7. Keywords: Comparative genomic hybridization
Project description:In this study, we describe the isolation and identification of Streptomyces isolates collected from traditional medicinal plants’ rhizosphere during a campaign in Hamedan Province, Iran. Traditional medicinal plants represent a rich and unique source for the isolation of Streptomyces and new antimicrobial compounds. This strain was isolated from the rhizosphere of Helichrysum rubicundum
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:Purpose: Panax vietnamensis Ha et Grushv., which contains various valuable ginsenosides, is an important herbal medicine of Vietnam. However, it is an endangered species listed in Vietnam Red Data Book due to over-harvseting. Investigation about genomic or trancriptomic resources is one of the necessary activities to conserve P. vietnamensis Materials and Methods:. In this study, we sequenced the transcriptomes of 1-year-old P. vietnamensis from leaves and roots using Illumina NovaSeqTM6000 system. Results: A total of 60,254,062 and 64,588,528 reads was obtained and then assembled into 45,495 and 49,133 unigenes for leaves and roots, respectively. More than 60% unigenes from two organs were functional annotated using at least one database among Kyoto Encyclopedia of Genes and Genomes, Pfam, Gene Ontology, NCBI non-redundant Protein, and Evolutionary genealogy of genes. Further, the predominant transcripts of each cDNA library were analyzed for different gene expression identification. In addition, 457 unigenes encoding enzymes involved in triterpenoid saponin biosynthesis via the mavelonate (MVA) and the non-MVA (also named as MEP pathways) were discovered.
Project description:Bacterial genomic plasticity and instability carry multiple functional genetic information in Streptomyces secondary metabolism. Our previously publication has reported an effective industrial Streptomyces strain, with a unique phenotype of the high clavulanic acid yield. The complete genome of strain F163-1 harboring a 136.9-kb giant region of plasticity (RGP) was sequenced. The chromosome and plasmid are densely packed by an exceptionally huge variety of potential secondary metabolic gene clusters, excluding production of putative antibiotics. Intriguingly, architecture and size differences of plasmid pSCL4 between F613-1 and ATCC 27064 suggest the pSCL4 plasmid evolving from pSCL4-like and pSCL2-like extrachromosomal replicons, in addition to the previously proposed ATCC 27064 mega-plasmid formation hypothesis through recombination between the smaller F613-1 pSCL4 plasmid arm regions and the linear chromosome. Comparative genomics systemically investigate secondary metabolism capacitates in this study indicates that frequent exchange of genetic materials between Streptomyces replicons may shape remarkable diversities of secondary metabolite repertoires. Consequently, the F613-1 strain seems to have evolved its specific genomic architectures and genetic patterns to meet the requirement in subsequent industrial processes.
