Elife
. 2024 Dec;

PMID: 39636223
The coordination of cell cycle progression and flagellar synthesis is a complex process in motile bacteria. In γ-proteobacteria, the localization of the flagellum to the cell pole is mediated by...

Front Microbiol
. 2021 Apr;
12:655239.
PMID: 33815347
Failure of the cell to properly regulate the number and intracellular positioning of their flagella, has detrimental effects on the cells' swimming ability. The flagellation pattern of numerous bacteria is...

Ortega D, Yang W, Subramanian P, Mann P, Kjaer A, Chen S, et al.
Nat Commun
. 2020 Apr;
11(1):2041.
PMID: 32341341
How complex, multi-component macromolecular machines evolved remains poorly understood. Here we reveal the evolutionary origins of the chemosensory machinery that controls flagellar motility in Escherichia coli. We first identify ancestral...

Environ Microbiol
. 2020 Mar;
22(10):4279-4294.
PMID: 32219943
Bacteria constantly experience changes to their external milieu and need to adapt accordingly to ensure their survival. Certain bacteria adapt by means of cellular differentiation, resulting in the development of...

Iyer S, Casas-Pastor D, Kraus D, Mann P, Schirner K, Glatter T, et al.
Nat Microbiol
. 2020 Jan;
5(3):395-406.
PMID: 31988380
A major form of transcriptional regulation in bacteria occurs through the exchange of the primary σ factor of RNA polymerase (RNAP) with an alternative extracytoplasmic function (ECF) σ factor. ECF...

ISME J
. 2019 Oct;
14(1):230-244.
PMID: 31624347
Bacteria experience changes in their environment and have developed various strategies to respond accordingly. To accommodate environmental changes, certain bacteria differentiate between specialized cell types. Vibrio parahaemolyticus is a marine...

Proc Natl Acad Sci U S A
. 2018 Dec;
115(52):13365-13370.
PMID: 30541885
The chemoreceptor array, a remarkably ordered supramolecular complex, is composed of hexagonally packed trimers of receptor dimers networked by a histidine kinase and one or more coupling proteins. Even though...

Brenzinger S, Pecina A, Mrusek D, Mann P, Volse K, Wimmi S, et al.
Mol Microbiol
. 2018 Jul;
109(5):694-709.
PMID: 29995998
The ability of most bacterial flagellar motors to reverse the direction of rotation is crucial for efficient chemotaxis. In Escherichia coli, motor reversals are mediated by binding of phosphorylated chemotaxis...

Mol Microbiol
. 2018 Jun;
109(3):365-384.
PMID: 29885061
Vibrio parahaemolyticus exists as swimmer and swarmer cells, specialized for growth in liquid and on solid environments respectively. Swarmer cells are characteristically highly elongated due to an inhibition of cell...

J Bacteriol
. 2018 Mar;
200(15):e00793-17.
PMID: 29531180
Most motile bacteria are able to bias their movement towards more favorable environments or to escape from obnoxious substances by a process called chemotaxis. Chemotaxis depends on a chemosensory system...
