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 ...

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 ...

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.

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 ...

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 ...

Direct observation of a crescent-shape chromosome in Bacillus subtilis [PDF]
, 2023 AbstractBacterial chromosomes are folded into tightly regulated three-dimensional structures to ensure proper transcription, replication, and segregation of the genomic information. Direct visualization of the chromosomal shape within bacterial cells is hampered by cell-wall confinement and the optical diffraction limit.

Competition for iron shapes metabolic antagonism betweenBacillus subtilisandPseudomonas marginalis [PDF]
The ISME JournalAbstractSiderophores have long been implicated in sociomicrobiology as determinants of bacterial interrelations. For plant-associated genera, like Bacillus and Pseudomonas, siderophores are well known for their biocontrol functions. Here, we explored the functional role of the Bacillus subtilis siderophore bacillibactin (BB) in an antagonistic ...

Cannibalism Shapes Biofilm Structure and Composition in Bacillus subtilis [PDF]
AbstractBacillus subtiliscan form robust colony biofilms in which different phenotypic subpopulations co-exist in highly structured and complex multicellular communities with tissue-like properties. These subpopulations provide the colony with an overall competitive fitness and the ability to respond to everchanging environmental conditions.

Control of cell shape and elongation by the rodA gene in Bacillus subtilis [PDF]
Molecular Microbiology, 1998 The Escherichia coli rodA and ftsW genes and the spoVE gene of Bacillus subtilis encode membrane proteins that control peptidoglycan synthesis during cellular elongation, division and sporulation respectively. While rodA and ftsW are essential genes in E. coli, the B.
