Acyl homoserine lactone-based quorum sensing in a methanogenic archaeon [PDF]
The ISME Journal, 2012 Abstract Acyl homoserine lactone (AHL)-based quorum sensing commonly refers to cell density-dependent regulatory mechanisms found in bacteria. However, beyond bacteria, this cell-to-cell communication mechanism is poorly understood. Here we show that a methanogenic archaeon, Methanosaeta harundinacea 6Ac, encodes an active quorum sensing

Caffeine as a Potential Quorum Sensing Inhibitor
Sensors, 2013 Quorum sensing enables bacteria to control the gene expression in response to the cell density. It regulates a variety of bacterial physiological functions such as biofilm formation, bioluminescence, virulence factors and swarming which has been shown ...

A Sinorhizobium meliloti-specific N-acyl homoserine lactone quorum-sensing signal increases nodule numbers in Medicago truncatula independent of autoregulation [PDF]
, 2016 N-acyl homoserine lactones (AHLs) act as quorum sensing signals that regulate cell-density dependent behaviors in many gram-negative bacteria, in particular those important for plant-microbe interactions.

Specificity of Acyl-Homoserine Lactone Synthases Examined by Mass Spectrometry [PDF]
Journal of Bacteriology, 2006 ABSTRACT Many gram-negative bacteria produce a specific set of N -acyl- l -homoserine-lactone (AHL) signaling molecules for the purpose of quorum sensing, which is a means of regulating coordinated gene expression in a cell-density-dependent manner.

A New Acyl-homoserine Lactone Molecule Generated by Nitrobacter winogradskyi [PDF]
Scientific Reports, 2016 AbstractIt is crucial to reveal the regulatory mechanism of nitrification to understand nitrogen conversion in agricultural systems and wastewater treatment. In this study, the nwiI gene of Nitrobacter winogradskyi was confirmed to be a homoserine lactone synthase by heterologous expression in Escherichia coli that synthesized several acyl-homoserine ...

A novel plasmid for detection of N-acyl homoserine lactones [PDF]
Plasmid, 2009 Many bacteria utilize acyl-homoserine lactones as cell to cell signals that can regulate the expression of numerous genes. Structural differences in acyl-homoserine lactones produced by different bacteria, such as acyl side chain length and the presence or absence of an oxy group, make many of the commonly used detection bioassays impractical for broad
