Project description:Mitomycin C is a DNA crosslinking agent. This experiment was carried out to determine the effect of Mitomycin C on genome wide transcription in Streptomyces venezuelae NRRL B65442.
Project description:BldB is a regulatory protein in Streptomyces and most species have a number of paralogs in their genomes. Deletion of BldB leads to a developmental deficiency and the colonies fail to produce aerial mycelium. In this experiment global gene expression was compared between the WT and BldB deletion strain of Streptomyces venezuelae NRRL B65442 after 10, 14 and 22 hours of growth in liquid cultures.
Project description:The BldC gene is required for the formation of aerial hyphae in Streptomyces venezuelae. It is a 68 amino acid DNA-binding protein related to the MerR family of transcription factors. BldC deletion strains are bald because they initiate sporulation prematurely, omitting the formation of aerial hyphae altogether. This RNA-Seq experiment was carried out to determine and quantify effect of BldC on the expression of all genes in the S. venezuelae genome after 10 and 14 hours of culture.
Project description:We isolated and sequenced mRNA from Streptomyces venezuelae grown on two different solid media that promote exploratory behaviour in this bacterial species. The data was analyzed using DeSeq2 to identify genes that undergo changes in expression over time as well as differences in gene expression patterns between the two media conditions.

Project description:The whiH gene is required for the differentiation of aerial hyphae into spores in Streptomyces species. It is a predicted member of the GntR family of transcription factors and has been shown to bind specifically to a sequence in its own promoter. This ChIP-Seq experiment was carried out to determine all the binding sites whiH binds to in the genome of Streptomyces venezuelae. A whiH deletion strain was made and a FLAG tagged whiH protein was expressed in it from a genome-integrated plasmid. Then anti-FLAG antibodies were used for chromatin immunoprecipitation followed by high throughput sequencing. The wild type Streptomyces venezuelae strain (ATCC 10712) was used as a negative control. For both the FLAG-WhiH strain and the WT strain, non-immunoprecipitated (total) DNA was also sequenced to arrive at a background enrichment which could be subtracted from the enrichment in the immunoprecipated sample.
