Identification of Bacillus subtilis genes for septum placement and shape determination [PDF]
Journal of Bacteriology, 1992 The Bacillus subtilis divIVB1 mutation causes aberrant positioning of the septum during cell division, resulting in the formation of small, anucleate cells known as minicells. We report the cloning of the wild-type allele of divIVB1 and show that the mutation lies within a stretch of DNA containing two open reading frames whose predicted products are ...

A Novel Spore Protein, ExsM, Regulates Formation of the Exosporium in Bacillus cereus and Bacillus anthracis and Affects Spore Size and Shape [PDF]
Journal of Bacteriology, 2010 ABSTRACT Bacillus cereus spores are assembled with a series of concentric layers that protect them from a wide range of environmental stresses. The outermost layer, or exosporium, is a bag-like structure that interacts with the environment and is composed of more than 20 proteins and glycoproteins. Here, we identified

Shaping an Endospore: Architectural Transformations During Bacillus subtilis Sporulation [PDF]
Annual Review of Microbiology, 2020 Endospore formation in Bacillus subtilis provides an ideal model system for studying development in bacteria. Sporulation studies have contributed a wealth of information about the mechanisms of cell-specific gene expression, chromosome dynamics, protein localization, and membrane remodeling, while helping to dispel the early view that bacteria lack ...

Overproduction of Flotillin Influences Cell Differentiation and Shape in Bacillus subtilis [PDF]
mBio, 2013 ABSTRACT Bacteria organize many membrane-related signaling processes in functional microdomains that are structurally and functionally similar to the lipid rafts of eukaryotic cells. An important structural component of these microdomains is the protein flotillin, which seems to act as a chaperone in recruiting other proteins to ...

Autolysins and shape change in rodA mutants of Bacillus subtilis [PDF]
Journal of Bacteriology, 1978 The biochemical phenotype of rodA mutants was not affected by the simultaneous presence in double mutants of the lyt gene which makes them 90 to 95% deficient in autolysin action. The only morphological effect of this deficiency on the expression of the rod gene was that both the rod and the coccal forms of the mutant failed to separate and grew as ...

Microbial Genomics, 2021 Bacillus anthracis, the causative agent of anthrax disease, is a worldwide threat to livestock, wildlife and public health. While analyses of genetic data from across the globe have increased our understanding of this bacterium’s population genomic structure, the influence of selective pressures on this successful pathogen is not ...

Shape of Nascent and Completed Poles of Bacillus subtilis [PDF]
Microbiology, 1984 The zonal dome model has previously been shown to fit the shape of the poles of the Gram-positive Streptococcus faecium quite accurately, but measurements of the angle that the pole of Bacillus subtilis makes with the cylinder portion of the cell show that the poles of this organism do not fit this model.

A sweet twist gets Bacillus into shape [PDF]
Molecular Microbiology, 2011 SummaryA protective organelle that is essential for viability under most conditions, the cell wall is a dynamic structure that is continuously remodelled with the growth of the bacterial cell. Because the cell wall also moulds the bacterium, the mechanisms of cell wall homeostasis can be deciphered using cell shape as a convenient proxy.

Chromosome segregation impacts on cell growth and division site selection in Corynebacterium glutamicum. [PDF]
, 2013 Spatial and temporal regulation of bacterial cell division is imperative for the production of viable offspring. In many rod-shaped bacteria, regulatory systems such as the Min system and nucleoid occlusion ensure the high fidelity of midcell divisome ...

Bacteria-shaped Gymnoplasts (Protoplasts) of Bacillus subtilis [PDF]
Journal of Bacteriology, 1969 Addition of glucose to the medium in which Bacillus subtilis was grown lowered the p H and increased the amount of lysylphosphatidylglycerol relative to the phosphatidylglycerol content of the membrane fraction.
