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:BldC is a transcriptional regulator essential for morphological development Streptomyces venezuelae. Although bldC deletion strain is unable to produce aerial hyphae, electron microscopy reveals that almost all of the colony biomass is in the form of spores rather than undifferentiated vegetative hyphae. This ChIP-chip experiment was carried out to determine the binding sites, and thence the regulon, of BldC in Streptomyces venezuelae. Cy3(IP):Cy5(Total) signal ratios in the wild type were compared to those in a bldC knockout strain.
Project description:The goal of this work was to determine where Lsr2 binds within the S. venezuelae chromosome, and to differentiate between direct versus indirect effects by comparing our ChIP-seq results with RNA-seq results
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:To gain insights into the processes underlying adaptation to phage infection, we performed RNA-seq analysis of infected mycelium from the plaque interface of S. venezuelae wild type harvested 24 h and 72 h after infection with Alderaan.
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:Identification of transcription start sites in Streptomyces venezuelae genome after 10, 14, 18 and, 24 hours of culture 5' tag RACE. The 4 time points correspond to late vegetative growth, initiation of sporulation, maturation of spores and, completion of sporulation.
