Introduction to Quorum Sensing Research in Diverse Microbial Systems

Abstract

Bacteria are able to produce and act in response to minute diffusible molecules called autoinducers (AI). These molecules amass as cell density enhancements and regulate the expression of set of genes to control diverse physiological functions by quorum sensing (QS). Several species of bacteria swap signal molecules to assist checking their own population densities. Until recently, it was contemplated that QS was an unusual phenomenon restricted to not many microbial species. Nevertheless, numerous novel exemplars of interbacterial and intrabacterial signaling mechanisms are documented. Amongst them, acyl-homoserine lactone (AHL) and QS signaling systems are perhaps the best implicated diverse chemical languages used by both Gram-positive and Gram negative bacteria respectively. QS systems have primarily smudged the difference involving unicellular and multicellular life forms. Several QS systems exceptionally essential to medicine and agriculture. These QS microbes could be undoubtedly expensive tools for biologists to inquire and comprehend the progress of cooperation and cell to cell communication, wherein the realistic applications of this acquaintance will befall well-known in conjunction with basic acquaintance.
