Title The role of (p)ppGpp in the heat shock response in B. subtilis
Organism Bacillus subtilis
Experiment type Expression profiling by high throughput sequencing
Summary Bacterial and eukaryotic cells survive an otherwise lethal heat shock once they are primed by a mild pre-heat shock. Using B. subtilis as a model organism, we investigated transcriptional changes during thermotolerance development at 37 °C, 48 °C, 53 °C and 48/53 °C and observed a comprehensive upregulation of genes of the general and heat shock response and the downregulation of many translation-related genes. In addition, strains lacking (p)ppGpp (ppGpp0) or with elevated (p)ppGpp levels (ΔrelA) were analyzed at 37 °C and 48 °C, revealing broad and pleiotropic transcripional changes mediated by (p)ppGpp in the ΔrelA mutant. In addition, our data suggests a contribution of the (p)ppGpp-mediated stringent response in the heat-mediated transcripional down-regulation of ribosomal genes and additional processes.
Overall design RNA of heat shocked B subtilis wild type, (p)ppGpp0 and ΔrelA strains
Please note that the *NoPP samples are special 5' enriched/depleted libraries which were used for TSS and promotor analysis and therefore, no processed (count or RPKM) data was generated.
