Extreme slow growth as alternative strategy to survive deep starvation in bacteria
Nature Communications, 2019 Bacteria can become dormant or form spores when starved for nutrients. Here, Gray et al. describe an alternative strategy, or ‘oligotrophic growth state’, showing that non-sporulating Bacillus subtilis cells can survive deep starvation conditions by ...

Studying biomolecule localization by engineering bacterial cell wall curvature. [PDF]
PLoS ONE, 2013 In this article we describe two techniques for exploring the relationship between bacterial cell shape and the intracellular organization of proteins. First, we created microchannels in a layer of agarose to reshape live bacterial cells and predictably ...

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.

Molecular mechanisms for the evolution of bacterial morphologies and growth modes
Frontiers in Microbiology, 2015 Bacteria exhibit a rich diversity of morphologies. Within this diversity, there is a uniformity of shape for each species that is replicated faithfully each generation, suggesting that bacterial shape is as selectable as any other biochemical adaptation.

Current Microbiology, 2003 The divIVB operon of Bacillus subtilis includes the cell shape-associated mre genes, including the membrane-associated proteins MreC and MreD. TnphoA mutagenesis was utilized to analyze a topological model for MreC. MreC has a short cytoplasmic amino terminus, a single membrane-spanning domain, and a large carboxy terminal domain which lies externally ...
