Bacillus subtilis 168, WT vs. ΔMWX, WT vs. Δ7ECF, Δ7ECF vs. ΔMWX.

(Submitter supplied) Bacillus subtilis encodes seven extracytoplasmic function (ECF) sigma factors. Three (sigma M, sigma W and simga X) mediate responses to cell envelope active antibiotics. The functions of sigma Y, sigma Z, sigma V, and YlaC remain largely unknown, and strong inducers of these sigma factors and their regulons have yet to be defined. Here, we define transcriptomic and phenotypic differences under non-stress conditions between strains carrying deletions in all seven ECF sigma factor genes (Δ7ECF), a sigMWX triple mutant (∆MWX), and the parental 168 strain. more...

Bacillus subtilis Δ7ECF Pxyl-sigV + xylose vs Δ7ECF Pxyl-sigV - xylose , 168 + lysozyme vs 168 - lysozyme

(Submitter supplied) To define the ECF sigma sigV - regulated genes during log growth phase in LB media under induction conditions for sigV The seven extracytoplasmic function (ECF) sigma (σ) factors of Bacillus subtilis are broadly implicated in resistance to antibiotics and other cell envelope stressors mediated, in part, by regulation of cell envelope synthesis and modification enzymes. We here define the regulon of σV as including at least 20 operons many of which are also regulated by σM, σX, or σW. more...

Sigma(M) regulated genes under antibiotic stress (vancomycin)

(Submitter supplied) Abstract of associated manuscript: The Bacillus subtilis extracytoplasmic function (ECF) sigma(M) factor is activated by cell envelope stress elicited by antibiotics, and by acid, heat, ethanol and superoxide stresses. Here, we have used several complementary approaches to identify genes controlled by sigma(M). In many cases, expression is only partially dependent on sigma(M) because of both overlapping promoter recognition with other ECF sigma factors and the presence of additional promoter elements. more...

Definition of the σ(W) Regulon of Bacillus subtilis in the Absence of Stress

(Submitter supplied) Comprison of the transcriptome of wild type Bacillus subtilis to the mutants sigW, rasP and prsW to select all candidate sigW regulated genes. We identified 89 genes as being sigW regulated, including several non-coding RNA's. The effects of rasP and prsW mutations on sigW regulated genes were relatively mild, implying that RasP or PrsW are not strictly required for sigW activation. The rasP mutant has a peliotropic phenotype, affecting competence development, protein secretion and membrane protein production. more...

The single ECF sigma factor of Xylella fastidiosa is involved in the heat shock response

(Submitter supplied) Genome sequence analysis of the bacterium Xylella fastidiosa revealed the presence of two genes, named rpoE and rseA, predicted to encode an ECF sigma factor and an anti-sigma factor, respectively. In this work, an rpoE null mutant was constructed in the citrus strain J1a12 and shown to be sensitive to exposure to heat shock and ethanol. To identify the X. fastidiosa σE regulon, global gene expression profiles were obtained by DNA microarray analysis of bacterial cells under heat shock identifying 23 sigmaE-dependent genes. more...

Global profiling of B. subtilis comparing wild-type to mutants with altered cytoplasmic membrane composition

(Submitter supplied) The Bacillus subtilis membrane contains diacylglycerol-based lipids with at least five distinct headgroups that impart distinct physical and chemical properties to the lipid bilayer. Here, we describe the phenotypic characterization of mutant strains lacking one or more of the following lipids: glycolipids (ugtP mutants), phosphatidylethanolamine (pssA and psd mutants), lysylphosphatidylglycerol (mprF), and cardiolipin (ywnE and ywjE). more...
