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.
