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:WhiA is an unusual transcriptional regulator found in Streptomyces species related to eukaryotic homing endonucleases. It plays a central role in sporulation in these bacteria. The aim of this transcription profiling experiment was to measure genome wide transcript levels in the wild type and the whiA deletion mutant at 7 time points from 8 to 20 hours during the growth cycle of Streptomyces venezuelae.
Project description:The WhiG sigma factor gene is required for spore formation is Streptomyces venezuelae. It is similar to the FliA sigma factor of E. coli. WhiG deletion strains are able to make aerial hyphae but are defective in the spore maturation. This ChIP-Seq experiment was carried out to determine all the binding sites WhiG binds to in the genome of Streptomyces venezuelae. Anti-WhiG polyclonal antibodies were used for ChIP-Seq of the wild type (WT) strain after 34 hours of growth in shaken cultures. A WhiG deletion strain was made and anti-WhiG antibodies were used for ChIP-Seq in the deletion strain after 34 hours of growth in shaken cultures. This was used as the negative control and ChIP-Seq peak positions in this were disregarded in the WT.
