Optimal Census by Quorum Sensing

open access: yesPLOS Computational Biology, 2015
Quorum sensing is the regulation of gene expression in response to changes in cell density. To measure their cell density, bacterial populations produce and detect diffusible molecules called autoinducers. Individual bacteria internally represent the external concentration of autoinducers via the level of monitor proteins.

QUORUM SENSING AND GROUP SELECTION [PDF]

open access: yesEvolution, 1998
Bacteria respond to cell density by expressing genes whose products are beneficial to the population as a whole. This response is brought about through the release into the medium of signaling molecules of the class N-acyl homoserine lactones, the concentration of which determines the level of gene expression.

Cheater suppression and stochastic clearance through quorum sensing.

open access: yesPLoS Computational Biology, 2022
The evolutionary consequences of quorum sensing in regulating bacterial cooperation are not fully understood. In this study, we reveal unexpected effects of regulating public good production through quorum sensing on bacterial population dynamics ...

The Lanthipeptide Synthetase-like Protein CA_C0082 Is an Effector of Agr Quorum Sensing in Clostridium acetobutylicum

open access: yes, 2023
Lanthipeptide synthetases are present in all domains of life. They catalyze a crucial step during lanthipeptide biosynthesis by introducing thioether linkages during posttranslational peptide modification.

Quorum sensing as a mechanism to harness the wisdom of the crowds

open access: yesNature Communications, 2023
Bacteria release and sense small molecules called autoinducers in a process known as quorum sensing. The prevailing interpretation of quorum sensing is that by sensing autoinducer concentrations, bacteria estimate population density to regulate the ...

Investigation of quorum sensing process in Bacillus licheniformis [PDF]

open access: yes, 2011
Quorum sensing is a well-established system of communication adopted by a number of bacterial, and some fungal, populations. This cell density dependent phenomenon is based on the accumulation of small diffusible molecules, termed as quorum sensing ...

Transcriptome analysis of acyl-homoserine lactone-based quorum sensing regulation in Yersinia pestis [corrected]. [PDF]

open access: yesPLoS ONE, 2013
The etiologic agent of bubonic plague, Yersinia pestis, senses self-produced, secreted chemical signals in a process named quorum sensing. Though the closely related enteric pathogen Y.

Dishonest Signaling in Microbial Conflicts

open access: yesFrontiers in Microbiology, 2022
Quorum sensing is a cell-cell communication system that bacteria use to express social phenotypes, such as the production of extracellular enzymes or toxins, at high cell densities when these phenotypes are most beneficial.

The Evolution of Quorum Sensing as a Mechanism to Infer Kinship.

open access: yesPLoS Computational Biology, 2016
Bacteria regulate many phenotypes via quorum sensing systems. Quorum sensing is typically thought to evolve because the regulated cooperative phenotypes are only beneficial at certain cell densities. However, quorum sensing systems are also threatened by

Quorum Sensing and Quorum Quenching in Food-Related Bacteria

open access: yes, 2020
Antimicrobial disinfection agents are usually misused, which can lead to the emergence of resistant microorganisms. This phenomenon is becoming a major problem worldwide with growing concern in public health.
