Although it is a very heterogeneous species, all the strains tested were able to produce short chain acyl homoserine lactone (AHL) quorum sensing signal molecules. (haifa.ac.il)
To understand how the Rhizobium leguminosarum rail-raiR quorum-sensing system is regulated, we identified mutants with decreased levels of RaiI-made N-acyl homoserinelactones (AHLs). (uba.ar)
Conjugative transfer of the Ti plasmids of Agrobacterium tumefaciens is controlled by a quorum-sensing system composed of TraR and its signal N-(3-oxo-octanoyl)-L-homoserine lactone. (illinois.edu)
Using nonpolar traI mutants, we examined the kinetics of induction of conjugative transfer in response to exogenous acyl-homoserine lactone. (illinois.edu)

Burkholderia mallei has two acyl-homoserine lactone (acyl-HSL) signal generator-receptor pairs and two additional signal receptors, all of which contribute to virulence. (elsevierpure.com)
Since raiR (and rail) expression is also reduced in cinI and cinR quorum-sensing mutants, we thought CinI-made AHLs may activate ExpR to induce raiR. (uba.ar)

Salmonella is an important foodborne pathogen, and it is unable to produce the quorum sensing signaling molecules called acyl-homoserine lactones (AHLs). (nih.gov)
Butyrolactones (2(3 em H /em )-furanones) from em Streptomyces /em types are structurally linked to the em N /em -acylhomoserine lactones and become well in quorum sensing [16,17]. (conferencedequebec.org)
Bottom line As the legislation of several bacterial processes is normally governed by quorum sensing systems, the selecting of organic and artificial furanones performing as agonists or antagonists suggests a fascinating tool to regulate and handle harmful AHL induced results.

Different bacterial types may generate different AHL analogs that differ long from the em N /em -acyl stores, which range from 4C14 carbons and in the substitution on the 3-placement of the medial side string [7-9]. (conferencedequebec.org)
