An improved integrative GFP-based vector for genetic engineering of Parageobacillus thermoglucosidasius facilitates the identification of a key sporulation regulator

AMB Express, 2023
Parageobacillus thermoglucosidasius is a thermophilic Gram-positive bacterium, which is a promising host organism for sustainable bio-based production processes. However, to take full advantage of the potential of P.

Abh, AbrB3, and Spo0A play distinct regulatory roles during polymyxin synthesis in Paenibacillus polymyxa SC2

Microbiology Spectrum
Polymyxins exhibit antibacterial activity against various gram-negative bacteria. However, the regulatory mechanisms of polymyxin synthesis remain unclear. Here, Abh, AbrB3, and Spo0A of Paenibacillus polymyxa SC2 were found to bind to P pmx via DNA pull-

Molecular mechanism of the smart attack of pathogenic bacteria on nematodes

Microbial Biotechnology, 2020
Summary Nematode–bacterial associations are far‐reaching subjects in view of their impact on ecosystems, economies, agriculture and human health. There is still no conclusion regarding which pathogenic bacteria sense nematodes.

Molecular genetics of surfactin and its effects on different sub-populations of Bacillus subtilis

Biotechnology Reports, 2021
Surfactin is a biosurfactant produced by Bacillus subtilis. The srfA operon, Sfp gene, and two quorum sensing systems are required for its production. The master regulator spo0A also plays an indispensable role in proper surfactin synthesis.

Dynamical consequences of bandpass feedback loops in a bacterial phosphorelay. [PDF]

PLoS ONE, 2011
Under conditions of nutrient limitation, Bacillus subtilis cells terminally differentiate into a dormant spore state. Progression to sporulation is controlled by a genetic circuit consisting of a phosphorelay embedded in multiple transcriptional feedback

Analysis of Sporulation in Bacillus cereus Biovar anthracis Which Contains an Insertion in the Gene for the Sporulation Factor σ^K

Pathogens, 2023
Bacillus cereus biovar anthracis (Bcbva) is an untypical pathogen causing a fatal anthrax-like disease in a variety of wildlife species in African rainforest areas. In contrast to Bacillus anthracis and most species of the B. cereus group, all strains of

Slowdown of growth controls cellular differentiation

Molecular Systems Biology, 2016
How can changes in growth rate affect the regulatory networks behavior and the outcomes of cellular differentiation? We address this question by focusing on starvation response in sporulating Bacillus subtilis.

The spo0A-sinI-sinR Regulatory Circuit Plays an Essential Role in Biofilm Formation, Nematicidal Activities, and Plant Protection in Bacillus cereus AR156

Molecular Plant-Microbe Interactions, 2017
The rhizosphere bacterium Bacillus cereus AR156 is capable of forming biofilms, killing nematodes, and protecting plants. However, the underlying molecular mechanisms of these processes are not well understood.

MstX and a putative potassium channel facilitate biofilm formation in Bacillus subtilis. [PDF]

PLoS ONE, 2013
Biofilms constitute the predominant form of microbial life and a potent reservoir for innate antibiotic resistance in systemic infections. In the spore-forming bacterium Bacillus subtilis, the transition from a planktonic to sessile state is mediated by ...

The trans-activation domain of the sporulation response regulator Spo0A revealed by X-ray crystallography [PDF]

, 2000
Sporulation in Bacillus involves the induction of scores of genes in a temporally and spatially co-ordinated programme of cell development. Its initiation is under the control of an expanded two-component signal transduction system termed a phosphorelay.
