Short Chain N-acyl Homoserine Lactone Production by Soil Isolate Burkholderia sp. Strain A9

Sensors, 2013
In the bacteria kingdom, quorum sensing (QS) is a cell-to-cell communication that relies on the production of and response to specific signaling molecules. In proteobacteria, N-acylhomoserine lactones (AHLs) are the well-studied signaling molecules.

A novel metagenomic short-chain dehydrogenase/reductase attenuates Pseudomonas aeruginosa biofilm formation and virulence on Caenorhabditis elegans. [PDF]

PLoS ONE, 2011
In Pseudomonas aeruginosa, the expression of a number of virulence factors, as well as biofilm formation, are controlled by quorum sensing (QS). N-Acylhomoserine lactones (AHLs) are an important class of signaling molecules involved in bacterial QS and ...

Degradation of Bacterial Quorum Sensing Signaling Molecules by the Microscopic Yeast Trichosporon loubieri Isolated from Tropical Wetland Waters

Sensors, 2013
Proteobacteria produce N-acylhomoserine lactones as signaling molecules, which will bind to their cognate receptor and activate quorum sensing-mediated phenotypes in a population-dependent manner.

Peptides as quorum sensing molecules : measurement techniques and obtained levels in vitro and in vivo [PDF]

, 2017
The expression of certain bacterial genes is regulated in a cell-density dependent way, a phenomenon called quorum sensing. Both Gram-negative and Gram-positive bacteria use this type of communication, though the signal molecules (auto-inducers) used by ...

Draft genome sequence of Citrobacter freundii strain ST2, a γ-proteobacterium that produces N-acylhomoserine lactones

Genomics Data, 2015
Citrobacter freundii strain ST2, isolated from the algae bloom sample, possesses an N-acylhomoserine lactone (AHL) production activity that secretes short-chain AHL molecules. In this study, we sequenced the complete genome of C.

Potato Plants Genetically Modified to Produce N-Acylhomoserine Lactones Increase Susceptibility to Soft Rot Erwiniae

Molecular Plant-Microbe Interactions, 2004
Many gram-negative bacteria employ N-acylhomoserine lactones (AHL) to regulate diverse physiological processes in concert with cell population density (quorum sensing [QS]).
