Red light activates the sigmaB-mediated general stress response of Bacillus subtilis via the energy branch of the upstream signaling cascade.
Avila-Pérez Marcela M van der Steen Jeroen B JB Kort Remco R Hellingwerf Klaas J KJ
Journal of bacteriology 20091130 3
The sigma(B)-dependent general stress response in the common soil bacterium Bacillus subtilis can be elicited by a range of stress factors, such as starvation or an ethanol, salt, or heat shock, via a complex upstream signaling cascade. Additionally, sigma(B) can be activated by blue light via the phototropin homologue YtvA, a component of the environmental branch of the signaling cascade. Here we use a reporter-gene fusion to show that sigma(B) can also be activated by red light via the energy ...[more]

Project description:The GraS/GraR two-component system has been shown to control cationic antimicrobial peptide (CAMP) resistance in the major human pathogen Staphylococcus aureus. We identified a highly conserved ten base pair palindromic sequence (5’ ACAAATTTGT 3’) located upstream from GraR-regulated genes (mprF and the dltA and vraFG operons), which we show to be essential for transcriptional regulation by GraR and induction in response to colistin, a bacterial CAMP, suggesting it is the likely GraR binding site. Genome-based predictions and transcriptome analysis revealed several novel GraR target genes. Global expression changes between the wild type strain HG001 (a rsbU+ variant of strain NCTC 8325) and a DgraSR mutant, grown to mid-exponential phase in TSB with 50 µg/ml colistin, were examined. Hybridizations were performed in triplicate using RNA isolated from independent cultures.

Project description:Liebal2012 - B.subtilis sigB proteolysis model
An important transcription factor of B.subsilis is sigma B
. Liebal et al. (2012) have performed experiments in B.subtilis wild type and mutant straits to test and validate a mathematical model of the dynamics of sigma B
activity. The following three models were constructed and their ability to fit the experimental data were tested. 1) Transcription inhibition model (MODEL1212180000), 2) sigma B
proteolysis model (MODEL1302080000) and 3) Post-transcriptional instability model (MODEL1302080001). This model corresponds to the sigma B
proteolysis model (MODEL1302080000).

Abstract:
In Bacillus subtilis the σ(B) mediated general stress response provides protection against various environmental and energy related stress conditions. To better understand the general stress response, we need to explore the mechanism by which the components interact. Here, we performed experiments in B. subtilis wild type and mutant strains to test and validate a mathematical model of the dynamics of σ(B) activity. In the mutant strain BSA115, σ(B) transcription is inducible by the addition of IPTG and negative control of σ(B) activity by the anti-sigma factor RsbW is absent. In contrast to our expectations of a continuous β-galactosidase activity from a ctc::lacZ fusion, we observed a transient activity in the mutant. To explain this experimental finding, we constructed mathematical models reflecting different hypotheses regarding the regulation of σ(B) and β-galactosidase dynamics. Only the model assuming instability of either ctc::lacZ mRNA or β-galactosidase protein is able to reproduce the experiments in silico. Subsequent Northern blot experiments revealed stable high-level ctc::lacZ mRNA concentrations after the induction of the σ(B) response. Therefore, we conclude that protein instability following σ(B) activation is the most likely explanation for the experimental observations. Our results thus support the idea that B. subtilis increases the cytoplasmic proteolytic degradation to adapt the proteome in face of environmental challenges following activation of the general stress response. The findings also have practical implications for the analysis of stress response dynamics using lacZ reporter gene fusions, a frequently used strategy for the σ(B) response.

Project description:The role of Pantonâ??Valentine leukocidin (PVL) in Staphylococcus aureus pathogenesis is controversial. Here, we show that an unintended point mutation in the agr P2 promoter of S.aureus caused the phenotypes in gene regulation and murine pneumonia attributed to PVL by Labandeiraâ??Rey et al. (Science 315:1130â??3, 2007). In agreement with previous studies that failed to detect similar effects of PVL using communityâ??associated methicillinâ??resistant S. aureus strains, we found no significant impact of PVL on gene expression or pathogenesis after we repaired the mutation. These findings further contribute to the idea that PVL does not have a major impact on S. aureus pathogenesis and resolve debate about its role in murine infection models. Moreover, our results demonstrate that a single nucleotide polymorphism in an intergenic region can dramatically impact bacterial physiology and virulence. Finally, our work emphasizes the need to frequently evaluate the integrity of the S. aureus agr locus. 7 hour growth, with 5 different strain comparisons

Project description:The transcriptional factor Zur plays a key role in regulating zinc homeostasis in Bacillus subtilis. The genomic sites bound by Zur were mapped using a chromatine immunoprecipitation approach. This allowed the identification of 80 inter- and intragenic chromosomal sites bound by Zur. This data set contains 2 samples. Immunoprecipitated (IP) DNA from Bacillus subtilis BSAS36 strain (BSB1, a tryptophan-prototrophic derivative 168 strain expressing a SPA-tagged Zur protein) were extracted from bacterial cells in the exponential growth phase. IP and whole-cell extract DNA were hybridized on tiling array to generate ChIP-on-chip profiles. Two biological replicates were anlyzed.

Project description:One of the first steps in bacterial cell division is the polymerization of the tubulin-like protein FtsZ at midcell. The dynamics of FtsZ polymerization is regulated by a set of proteins among which ZapA. A zapA mutation does not result in a clear phenotype in Bacillus subtilis. In this study we used a synthetic-lethal screen to find genes that become essential when ZapA is absent. Three transposon insertions were found in yvcL. Deletion of yvcL in a wild type background had only a mild effect on growth, but a yvcL zapA double mutant is very filamentous and sick. This filamentation is caused by a strong reduction in FtsZ polymerization, suggesting that YvcL is involved in an early stage of cell division. YvcL is 25 % identical and 50 % similar to the Streptomyces coelicolor transcription factor WhiA. WhiA is required for septation of aerial hyphae during sporulation. Using GFP fusions, we show that YvcL localizes at the nucleoid. Surprisingly, transcriptome analyses in combination with a ChIP on chip assay did not provide clear evidence that YvcL functions as a transcription factor. To gain more insight into the function of YvcL, we searched for suppressors of the filamentous phenotype of a M-bM-^HM-^FyvcL M-bM-^HM-^FzapA mutant. Transposon insertions in gtaB and pgcA restored normal cell division of the double mutant. The corresponding proteins have been implemented in the metabolic sensing of cell division. We conclude that YvcL (WhiA) is involved in cell division in B. subtilis through an as yet unknown mechanism.

Project description:RNAseq of exponentially growing cultures of the four agr prototype strains used in the study to investigate if differential expression of regulators interacting with the agr system could explain the differences in AIP sensitivity. Abstract Staphylococcus aureus both colonizes humans and causes severe virulent infections. Virulence is regulated by the agr quorum sensing system and its autoinducing peptide (AIP), with dynamics at the single-cell level across four agr-types – each defined by distinct AIP sequences and capable of cross-inhibition – remaining elusive. Employing microfluidics, time-lapse microscopy, and deep-learning image analysis, we uncovered significant differences in AIP sensitivity among agr-types. We observed bimodal agr activation, attributed to intergenerational phenotypic stability and influenced by AIP concentration. Upon AIP stimulation, agr III showed AIP insensitivity, while agr II exhibited increased sensitivity and prolonged generation time. Beyond expected cross-inhibition of agr I by heterologous AIP II and III, the presumably cross-activating AIP IV also inhibited agr I. Community interactions across different agr-type pairings revealed four main patterns: stable or switched dominance, and delayed or stable dual activation, influenced by community characteristics. These insights underscore the potential of personalized treatment strategies considering virulence and genetic diversity.
