(Submitter supplied) This study is based on two microarray datasets, in one hand a phase transition comparison using the expression profiles of 630E strain after 4h and 10h of growth. In other hand a comparison at 10h of growth between a mutant of the sigH gene and the WT strains. This experimental procedure was designed to investigate the effect of sigH in the growth phase transition of Clostridium difficile. This SuperSeries is composed of the SubSeries listed below.

(Submitter supplied) Compartment-specific control of gene expression during Bacillus subtilis sporulation is governed by a cascade of four sigma factors, sigmaF and sigmaG in the forespore and sigmaE and sigmaK in the mother cell. In this work, we combined transcriptional analyses and transcriptional start site mapping to define the sigmaF, sigmaE, sigmaG and sigmaK regulons in Clostridium difficile. A total of about 225 genes were under the control of these sigma factors: 25 in the sigmaF regulon, 97 sigmaE-dependent genes, 50 sigmaG-governed genes and 56 genes specifically controlled by sigmaK. more...

(Submitter supplied) Purpose: The goal of this study was to identify genes whose expression is induced during sporulation in a Spo0A-, σF-, σE-, σG-, and σK-dependent manner. Methods: Whole genome RNA sequencing was performed on wildtype, spo0A-, sigF-, sigE-, sigG-, and sigK- C. difficile strains (strain 630 background; JIR8094 = parent strain), and the transcriptional profiles of the different mutants during growth on 70:30 agar plates were determined using an Illumina HiSeq1000. more...

(Submitter supplied) Clostridium acetobutylicum, the endospore-forming anaerobe best known for its ABE (acetone-butanol-ethanol) fermentation, has received renewed attention recently for the biological production of butanol, both for bulk chemical production and as a potential biofuel. With butanol production in mind, most of the recent research on C. acetobutylicum has focused on increasing butanol production, tolerance to butanol, and optimizing it for various substrates. more...

(Submitter supplied) Genes encoding the alternative sigma factor SigmaB, involved in the general stress response in firmicutes, as well as its regulators are present in the genome of the enteropathogen Clostridium difficile. We inactivated the sigB gene using the ClosTron technology in order to identify the role of this sigma factor in the physiology of this bacterium. Transcriptomic experiments showed that SigB positively and negatively controlls several genes involved in different cellular processes such as metabolism, sporulation and stress response.

(Submitter supplied) In this study, RNA-seq was used to compare the transcriptomes of Listeria monocytogenes 10403S::ΔBCHL Prha-sigH and ΔBCHL Prha. RNA-seq was performed on ΔBCHL Prha-sigH and ΔBCHL Prha RNA samples representing three independent biological replicates at log phase in Brain Heart Infusion (BHI) broth under rhamnose induction. Indexed and purified cDNA libraries (6 libraries including 3 replicates for 2 strains) were loaded together onto an independent flow cell without any other samples; sequencing was carried out by running Hiseq 2500 (single-end, 150-bp per read). more...
