Biotic and abiotic surfaces in marine waters are rapidly colonized by microorganisms.
Surface colonization and subsequent biofilm formation and development provide numerous …

Motile Escherichia coli cells track gradients of attractant and repellent chemicals in their
environment with transmembrane chemoreceptor proteins. These receptors operate in …

Microorganisms are found everywhere, and they are closely associated with plants.
Because the establishment of any plant–microbe association involves chemical …

Chemotaxis allows bacteria to follow gradients of nutrients and other environmental stimuli.
The bacterium Escherichia coli performs chemotaxis via a run-and-tumble strategy in which …

Chemoreceptors in bacteria detect a variety of signals and feed this information into
chemosensory pathways that represent a major mode of signal transduction. The five …

Widespread pollution of terrestrial ecosystems with petroleum hydrocarbons (PHCs) has
generated a need for remediation and, given that many PHCs are biodegradable, bio-and …

Beneficial plant–microbe associations play critical roles in plant health. Bacterial chemotaxis
provides a competitive advantage to motile flagellated bacteria in colonization of plant root …

Chemotactic responses in bacteria require large, highly ordered arrays of sensory proteins
to mediate the signal transduction that ultimately controls cell motility. A mechanistic …

Bacterial chemoreceptors, histidine kinase CheA, and coupling protein CheW form clusters
of chemotaxis signaling complexes. In signaling complexes kinase activity is enhanced …

Spatial organization of signalling is not an exclusive property of eukaryotic cells. Despite the
fact that bacterial signalling pathways are generally simpler than those in eukaryotes, there …
