(Submitter supplied) The alternative sigma factor sigmaB has an important role in the acquisition of stress-resistance in many gram-positive bacteria. In the foodborne pathogen Bacillus cereus sigmaB is activated strongly upon a heat shock and other stress conditions. Here we describe the identification of the set of sigmaB-regulated genes in B. cereus by DNA microarray analysis of the transcriptome upon a mild heat shock. more...

(Submitter supplied) Spx, a member of the ArsC (arsenate reductase) protein family, is highly conserved in Gram-positive bacteria, where it interacts with RNA polymerase to activate transcription in response to toxic oxidants.  In Bacillus anthracis, resistance to oxidative stress requires the activity of two paralogous forms of Spx, SpxA1 and SpxA2.   Suppressor mutations were identified in spxA1 mutant cells that conferred resistance to hydrogen peroxide. more...

(Submitter supplied) To uncover the effects of KrrA regulation on gene transcription and define the bacterial response imposed by this regulation, a transcriptomic study was carried out in which Bacillus anthracis krrA was compared to WT in two growth conditions: LB in the presence or absence of ‘205.

(Submitter supplied) The two-component system CBO0366/CBO0365 was recently demonstrated to have a role in cold tolerance of Group I Clostridium botulinum ATCC 3502. The mechanisms under its control, ultimately resulting in increased sensitivity to low temperature, are unknown. A transcriptomic analysis with DNA microarrays was performed to identify the differences in global gene expression patterns of the wild-type ATCC 3502 and a derivative mutant with insertionally inactivated cbo0365 at 37 °C and 15 °C. more...

(Submitter supplied) To infer the biological meaning from transcriptome data, it is useful to focus on genes that are regulated by the same regulator, i.e., regulons. Unfortunately, current gene set enrichment analysis (GSEA) tools do not consider whether a gene is activated or repressed by a regulator. This distinction is crucial when analyzing regulons since a regulator can work as an activator of certain genes and as a repressor of other genes, yet both sets of genes belong to the same regulon. more...
