Frontiers in Microbiology, 2019 The most common quorum sensing (QS) system in Gram-negative bacteria consists of signaling molecules called N-acyl-homoserine lactones (AHLs), which are synthesized by an enzyme AHL synthase (LuxI) and detected by a transcriptional regulator (LuxR) that ...

Detection of quorum-sensing-related molecules in [PDF]
, 2008 Background Cell-to-cell communication (also referred to as quorum sensing) based on N-acyl-homoserine lactones (AHLs) is a widespread response to environmental change in Gram-negative bacteria.

Quorum sensing for improved production of industrially useful products from filamentous fungi [PDF]
, 2014 Quorum sensing (QS) is a cell density dependant phenomena utilized as a communication process among microorganisms to regulate their physiological responses. QS depends on the production and release of low molecular weight, diffusible chemical signalling

Expression of virulence genes in luminescent and nonluminescent isogenic vibrios and virulence towards gnotobiotic brine shrimp (Artemia franciscana) [PDF]
, 2011 Aims: This study aimed to evaluate the expression levels of virulence gene regulators (luxR and toxR) and virulence factors (serine protease, metalloprotease and haemolysin) in luminescent and nonluminescent isogenic Vibrio harveyi and Vibrio campbellii ...

A gene cluster in Agrobacterium vitis homologous to polyketide synthase operons is associated with grape necrosis and hypersensitive response induction on tobacco [PDF]
, 2017 Here, we identify a cluster of eight genes on chromosome 2 of Agrobacterium vitis that is associated with the ability of the bacterium to cause a hypersensitive response on tobacco and a necrosis of grape shoot explants. Three of these genes share a high
