Extracytoplasmic function σ factors (ECFs) represent a fundamental and widely distributed
principle of bacterial signal transduction that connects the perception of a stimulus (input) …

The general stress response (GSR) is a widely conserved response that allows bacteria to
cope with a multitude of stressful conditions. In the past years the PhyR–NepR–σ EcfG …

In natural environments, bacteria often adhere to surfaces where they form complex
multicellular communities. Surface adherence is determined by the biochemical composition …

Detection of blue light (BL) via flavin‐binding photoreceptors (Fl‐Blues) has evolved
throughout all three domains of life. Although the main BL players, that is light, oxygen and …

The Alphaproteobacteria uniquely integrate features of two-component signal transduction
and alternative σ factor regulation to control transcription of genes that ensure growth and …

During its cell cycle, the bacterium Caulobacter crescentus switches from a motile, free-living
state, to a sessile surface-attached cell. During this coordinated process, cells undergo …

The ubiquitous bacterium Caulobacter crescentus holds promise to be used in
bioremediation applications due to its ability to mineralize U (VI) under aerobic conditions …

Two-component signaling systems (TCSs) are comprised of a sensory histidine kinase and
a response regulator protein. In response to environmental changes, sensor kinases directly …

Brucella spp. are adept at establishing a chronic infection in mammals. We demonstrate that
core components of the α-proteobacterial general stress response (GSR) system, PhyR and …

Due to their intimate physical interactions with the environment, surface polysaccharides are
critical determinants of fitness for bacteria. Caulobacter crescentus produces a specialized …
