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

Quorum sensing is a cell-cell communication process in which bacteria use the production
and detection of extracellular chemicals called autoinducers to monitor cell population …

Praise for the first edition:… superb, beautifully written and organized work that takes an
engineering approach to systems biology. Alon provides nicely written appendices to …

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 …

For organisms to coordinate their growth and development with nutrient availability, they
must be able to sense nutrient levels in their environment. Here, we review select nutrient …

Bacteria must be able to respond to a changing environment, and one way to respond is to
move. The transduction of sensory signals alters the concentration of small phosphorylated …

Robustness, the ability to maintain performance in the face of perturbations and uncertainty,
is a long-recognized key property of living systems. Owing to intimate links to cellular …

Cell‐surface receptors acquire information from the extracellular environment and
coordinate intracellular responses. Many receptors do not operate as individual entities, but …

Bacterial chemotaxis, the directed movement of cells along gradients of chemoattractants, is
among the best-characterized subjects in molecular biology,,,,,,,,–, but much less is known …

Bacteria communicate and coordinate their behaviour at the intra-and interspecies levels by
producing and sensing diverse extracellular small molecules called autoinducers …
