Synthesis and analysis of stable isotope-labelled N-acyl homoserine lactones [PDF]

, 2016
Aliphatic aldehydes were deuterated at the alpha-position via a base-catalyzed exchange reaction with D2O. These deuterated building blocks were used for the synthesis of labelled analogues of quorum sensing signal molecules belonging to the three major ...

Priming winter wheat seeds with the bacterial quorum sensing signal N-hexanoyl-L-homoserine lactone (C6-HSL) shows potential to improve plant growth and seed yield.

PLoS ONE, 2019
Several model plants are known to respond to bacterial quorum sensing molecules with altered root growth and gene expression patterns and induced resistance to plant pathogens.

Occurrence of N-acyl-L-homoserine lactones in extracts of some Gram-negative bacteria evaluated by gas chromatography–mass spectrometry

, 2007
Acylated homoserine lactones (AHLs) are self-generated signal molecules that mediate population density-dependent gene expression (quorum sensing) in a variety of Gram-negative bacteria.

The GCR1 and GPA1 Participate in Promotion of Arabidopsis Primary Root Elongation Induced by N-Acyl-Homoserine Lactones, the Bacterial Quorum-Sensing Signals

Molecular Plant-Microbe Interactions, 2012
Many gram-negative bacteria use N-acyl-homoserine lactones (AHL) as quorum-sensing signals to coordinate their collective behaviors. Accumulating evidence indicates that plants can respond to AHL. However, little is known about the molecular mechanism of

Acyl homoserine lactones induce early response in the airway.

, 2009
Acyl homoserine lactones (AHLs) are intercellular signaling molecules used in quorum sensing by Gram-negative bacteria. We studied the early effects on the rat airway of in vivo intratracheal administration of AHLs (i.e., P. aeruginosa and B. cepacia) to

Interpopulation Signaling via N-Acyl-Homoserine Lactones among Bacteria in the Wheat Rhizosphere

Molecular Plant-Microbe Interactions, 1998
The biological control bacterium Pseudomonas aureofaciens 30-84 utilizes an N-acyl-homoserine lactone (AHL) signal molecule to control phenazine antibiotic production in the wheat rhizosphere (D. W. Wood and L. S. Pierson III, Gene 168:49-53, 1996).

Evidence for Acyl Homoserine Lactone signal production in bacteria associated with marine sponges

, 2004
We report for the first time the production of acyl homoserine lactones (AHLs) by bacteria associated with marine sponges. Given the involvement of AHLs in bacterial colonization of many higher organisms, we speculate that such quorum sensing signals ...

A Variant Quorum Sensing System in Aeromonas veronii MTCC 3249

Sensors, 2012
We have investigated the quorum sensing control in Aeromonas veronii MTCC 3249, originally isolated as A. culicicola from the midgut of Culex quinquefasciatus.

Metabolism of Acyl-Homoserine Lactone Quorum-Sensing Signals by Variovorax paradoxus

, 2000
Acyl-homoserine lactones (acyl-HSLs) serve as dedicated cell-to-cell signaling molecules in many species of the class Proteobacteria . We have addressed the question of whether these compounds can be degraded biologically.
