The HmrABCX pathway regulates the transition between motile and sessile lifestyles in Caulobacter crescentus by a HfiA-independent mechanism

S. Zappa, C. Berne, R. I. Morton, J. De Stercke, Y. V. Brun

This study identifies a phosphorelay pathway, HmrABCX, that regulates the transition from motile to sessile lifestyle in Caulobacter crescentus independently of HfiA, and shows its role in environmental stress responses.

eDNA-stimulated cell dispersion from Caulobacter crescentus biofilms upon oxygen limitation is dependent on a toxin-antitoxin system.

C. Berne, S. Zappa, Y. V. Brun

The paper shows that in Caulobacter crescentus biofilms, the toxin-antitoxin system ParDE4 promotes cell death under oxygen limitation, which increases eDNA release and drives cell dispersal to new environments.

The two chemotaxis in Caulobacter crescentus operons play different roles in chemotaxis and biofilm regulation

C. Berne, Y. V. Brun

This paper identifies a novel role for two chemotaxis operons in regulating holdfast production and biofilm formation in Caulobacter crescentus by modulating hfiA expression.

Comparative analysis of ionic strength tolerance between freshwater and marine Caulobacterales adhesins

N. K. Chepkwony, C. Berne, Y. V. Brun

This study compares the ionic strength tolerance of holdfasts in marine and freshwater Caulobacterales, finding that marine holdfasts tolerate higher ionic strength due to differences in composition and structure.
