Project description:To identify unique gene expression in higher antibiotics producing Streptomyces coelicolor strain, non-producer M1146 and the derivative strain M1146+ACT (M1146 with actinorhodin biosynthetic genes cluster) was choosen for comparative transcriptome analysis. The genes with different gene expression might be key genes important for antibiotics production.

Project description:The RNA sequencing approach was utilized to carry out a comparative transcriptome analysis between Streptomyces hygroscopicus 5008 wild-type and a genetically engineered strain. The A-factor-like cascade play an important role in the regulation of validamycin biosynthesis by Streptomyces hygroscopicus 5008, and the pleiotropic regulator AdpA-H may positively regulate the transcription of gene cluster for the biosynthesis. shbR1 and shbR3 as the A-factor receptor homolog genes, could repress the transcription of AdpA-H. By tandem deletions of these genes, the production and productivity of validamcyin was significantly enhanced. To explore the effects of the shbR1/R3 double deletion of the overall cellular metabolism, the RNA sequencing approach was utilized to carry out a comparative transcriptome analysis between wild-type and shbR1/shbR3 double mutant (genetically engineered strain).

Abstract:
BACKGROUND: The transition from exponential to stationary
phase in Streptomyces coelicolor is accompanied by a major
metabolic switch and results in a strong activation of
secondary metabolism. Here we have explored the underlying
reorganization of the metabolome by combining computational
predictions based on constraint-based modeling and detailed
transcriptomics time course observations. RESULTS: We
reconstructed the stoichiometric matrix of S. coelicolor,
including the major antibiotic biosynthesis pathways, and
performed flux balance analysis to predict flux changes that
occur when the cell switches from biomass to antibiotic
production. We defined the model input based on observed
fermenter culture data and used a dynamically varying objective
function to represent the metabolic switch. The predicted
fluxes of many genes show highly significant correlation to the
time series of the corresponding gene expression data.
Individual mispredictions identify novel links between
antibiotic production and primary metabolism. CONCLUSION: Our
results show the usefulness of constraint-based modeling for
providing a detailed interpretation of time course gene
expression data.

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.
