In biology, quorum sensing or quorum signalling (QS) is the ability to detect and respond to cell population density by gene regulation. As one example, QS enables bacteria to restrict the expression of specific genes to the high cell densities at which the resulting phenotypes will be most beneficial. … Meer weergeven Quorum sensing was first reported in 1970, by Kenneth Nealson, Terry Platt, and J. Woodland Hastings, who observed what they described as a conditioning of the medium in which they had grown the bioluminescent marine … Meer weergeven Examples Methanosaeta harundinacea 6Ac Methanosaeta harundinacea 6Ac, a methanogenic archaeon, produces carboxylated acyl homoserine lactone compounds that facilitate the transition from growth … Meer weergeven QS is important to plant-pathogen interactions, and their study has also contributed to the QS field more generally. The first Meer weergeven Social insect colonies are an excellent example of a decentralized system, because no individual is in charge of directing or making decisions for the colony. … Meer weergeven Some of the best-known examples of quorum sensing come from studies of bacteria. Bacteria use quorum sensing to regulate certain Meer weergeven A mechanism involving arbitrium has recently been described in bacteriophages infecting several Bacillus species. The viruses communicate with each other to ascertain their own density compared to potential hosts. They use this information to decide … Meer weergeven Quorum quenching is the process of preventing quorum sensing by disrupting signalling. This is achieved by inactivating signalling … Meer weergeven Web12 jun. 2024 · Bacterial communication relies on versatile chemical signaling molecules called autoinducers, which regulate bacterial gene expression in a process known as …
Quorum Sensing - an overview ScienceDirect Topics
Web22 feb. 2016 · QS is a mechanism that regulates gene expression according to cellular density. This mechanism operates through the release of signal molecules known as ‘autoinducers’, so called because they can act on the same cell that releases them, and are able to trigger gene expression throughout the population, causing a global response. clinton elementary school ny
