A large number of Gram-negative pathogens produce N-acylhomoserine lactones (AHLs) as signal molecules for quorum sensing (QS). This cell-cell communication system allows them to coordinate gene expression and regulate virulence. Therefore, strategies to inhibit QS are promising for the control

Sensors (Basel, Switzerland), 12(3), 2851-2873 (2012-06-28)
Bacteria of the genus Bradyrhizobium are able to establish a symbiotic relationship with peanut (Arachis hypogaea) root cells and to fix atmospheric nitrogen by converting it to nitrogenous compounds. Quorum sensing (QS) is a cell-cell communication mechanism employed by a

Bacteria use small diffusible molecules to exchange information in a process called quorum sensing (QS). An important class of quorum sensing molecules used by Gram-negative bacteria is the family of N-acylhomoserine lactones (HSL). It was recently discovered that a degradation

Methanosaeta harundinacea 6Ac displayed a cell-density dependent cell morphology transition between short rods (3 microm - 5 microm) and filaments ( >200 microm), implying a quorum sensing system in this archaeon. This study aimed to confirm that cell morphology related

Quorum-sensing (QS) is a regulatory mechanism with which bacteria regulate the gene expression according to their population density. Pseudomonas aeruginosa regulates the expression of multiple genes via a hierarchical quorum-sensing cascade through LasR and RhlR and their cognate signal molecules
