Talking To Themselves: Autoregulation And Quorum Sensing In Fungi, Deborah A. Hogan Apr 2006

Talking To Themselves: Autoregulation And Quorum Sensing In Fungi, Deborah A. Hogan

Open Dartmouth: Faculty Open Access Scholarship

Extracellular autoinducing compounds in the supernatants of microbial cultures were first recognized for their roles in the induction of genetic competence in gram-positive bacteria and in the regulation of light production in marine vibrios. In 1994, this form of population-level regulation in microbes was dubbed “quorum sensing” since it enabled bacterial cells to chemically measure the density of the surrounding population. Subsequently, many examples of cell density-dependent regulation by extracellular factors have been found in diverse microorganisms. The widespread incidence of diverse quorum-sensing systems strongly suggests that regulation in accordance with cell density is important for the success of microbes ...
