Quorum sensing with pheromones [PDF]

open access: yesNature Microbiology, 2019
The vast majority of fungi reproduce sexually and use secreted pheromones to signal to each other. A study now shows that these signalling molecules in the fungal plant pathogen Fusarium oxysporum activate a density-dependent autocrine signal that controls asexual spore germination.

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.

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 ...

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.

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 ...

Quorum Sensing of Periodontal Pathogens

open access: yesActa Stomatologica Croatica, 2015
The term ‘quorum sensing’ describes intercellular bacterial communication which regulates bacterial gene expression according to population cell density. Bacteria produce and secrete small molecules, named autoinducers, into the intercellular space.

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

Inhibition of Pseudomonas aeruginosa Quorum Sensing by Curcuma xanthorrhiza Roxb. Extract

open access: yesJournal of Pure and Applied Microbiology, 2019
Microorganisms such as Pseudomonas aeruginosa have always been adaptable in surviving the harsh environment such as antimicrobial agents via the quorum sensing (QS) mechanism.

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.

Drugs for the Quorum Sensing Inhibition of Oral Biofilm: New Frontiers and Insights in the Treatment of Periodontitis

open access: yesPharmaceutics, 2022
Chemical molecules are used by microorganisms to communicate with each other. Quorum sensing is the mechanism through which microorganisms regulate their population density and activity with chemical signaling.
