Cheaters shape the evolution of phenotypic heterogeneity in Bacillus subtilis biofilms [PDF]
The ISME Journal, 2018 ABSTRACTBiofilms are closely packed cells held and shielded by extracellular matrix composed of structural proteins and exopolysaccharides (EPS). As matrix components are costly to produce and shared within the population, EPS-deficient cells can act as cheaters by gaining benefits from the cooperative nature of EPS producers.

Colony shape as a genetic trait in the pattern-forming Bacillus mycoides [PDF]
BMC Microbiology, 2002 Bacillus mycoides Flügge, a Gram-positive, non-motile soil bacterium assigned to Bacillus cereus group, grows on agar as chains of cells linked end to end, forming radial filaments curving clock- or counter-clockwise (SIN or DX morphotypes). The molecular mechanism causing asymmetric curving is not known: our working hypothesis considers regulation of ...

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.

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.

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.

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 ...

Time dynamics of the Bacillus cereus exoproteome are shaped by cellular oxidation [PDF]
Frontiers in Microbiology, 2015 At low density, Bacillus cereus cells release a large variety of proteins into the extracellular medium when cultivated in pH-regulated, glucose-containing minimal medium, either in the presence or absence of oxygen. The majority of these exoproteins are putative virulence factors, including toxin-related proteins. Here, B.

Shaping an Endospore: Architectural Transformations During Bacillus subtilis Sporulation
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 ...

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 ...

CRISPR-Cas9 Shaped Viral Metagenomes Associated with Bacillus subtilis
, 2022 Phages are viruses of bacteria and have been known for over a century. They do not have a metabolism or protein synthesis machinery and rely on host cells for replication. The model organism Bacillus subtilis has served as a host strain for decades and enabled the isolation of many unique viral strains.
