WebJun 12, 2024 · The quorum sensing system V. cholerae uses to regulate biofilm formation. V. cholerae ’s insidious but abrupt biofilm formation starts immediately after it enters a person’s small intestine. Individual V. cholerae produce species-specific autoinducers as they reproduce. V. cholerae regulates its response to autoinducers via LuxO. 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. Many … See more 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 … See more Examples Methanosaeta harundinacea 6Ac Methanosaeta harundinacea 6Ac, a methanogenic archaeon, produces carboxylated acyl … See more 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 whether … See more Quorum quenching is the process of preventing quorum sensing by disrupting signalling. This is achieved by inactivating signalling enzymes, by introducing molecules that … See more Some of the best-known examples of quorum sensing come from studies of bacteria. Bacteria use quorum sensing to regulate certain phenotype expressions, which in turn, coordinate their behaviours. Some common phenotypes include biofilm formation, See more QS is important to plant-pathogen interactions, and their study has also contributed to the QS field more generally. The first X-ray crystallography results for some of the key proteins were those of Pantoea stewartii subsp. stewartii in maize/corn See more 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.
