Quorum sensing is a regulatory system used by bacteria for controlling gene expression in response to increasing cell density.{15370} This regulatory process manifests itself with a variety of phenotypes including biofilm formation and virulence factor production.{13434} Coordinated gene expression is achieved by the production, release, and detection of small diffusible signal molecules called autoinducers. Autoinducers containing a phenylacetanoyl group in the acyl chain display a wide range of inhibitory and activating effects on various R protein transcriptional regulators.{26043,26044,15550} N-phenylacetyl-L-Homoserine lactone is a small diffusible signaling molecule involved in quorum sensing in the model symbiont V. fischeri and the pathogens A. tumefaciens and P. aeruginosa.{15550,26045} It has been reported to antagonize TraR signaling in A. tumefaciens, LasR signaling in E. coli, and LuxR signaling in V. fischeri.{26044}
