Quorum-Sensing System Affects Gall Development Incited by Pantoea agglomerans pv. gypsophilae

Molecular Plant-Microbe Interactions, 2008
The quorum-sensing (QS) regulatory system of the gall-forming Pantoea agglomerans pv. gypsophilae was identified. Mass spectral analysis, together with signal-specific biosensors, demonstrated that P. agglomerans pv.

Influence of food system conditions on N-acyl-L-homoserine lactones production by Aeromonas spp. [PDF]

, 2006
Eleven of 13 Aeromonas strains were shown to produce AHLs. Results of TLC showed that N-butanoyl-L-homoserine lactone (C4-HSL) was the main AHL produced in LB medium at 30 degrees C.

Non-antibiotic quorum sensing inhibitors acting against N-acyl homoserine lactone synthase as druggable target [PDF]

, 2014
YesN-acylhomoserine lactone (AHL)-based quorum sensing (QS) is important for the regulation of proteobacterial virulence determinants. Thus, the inhibition of AHL synthases offers non-antibiotics-based therapeutic potentials against QS-mediated bacterial

N-Acyl Homoserine Lactones in Diverse Pectobacterium and Dickeya Plant Pathogens: Diversity, Abundance, and Involvement in Virulence [PDF]

, 2012
Soft-rot bacteria Pectobacterium and Dickeya use N-acyl homoserine lactones (NAHSLs) as diffusible signals for coordinating quorum sensing communication.

Interference with the germination and growth of Ulvazoospores by quorum-sensing molecules from Ulva-associated epiphytic bacteria [PDF]

, 2013
Ulva zoospores preferentially settle on N-acylhomoserine lactone (AHL) producing marine bacterial biofilms. To investigate whether AHL signal molecules also affect the success and rate of zoospore germination in addition to zoospore attraction, the ...

Cross-species activation of hydrogen cyanide production by a promiscuous quorum-sensing receptor promotes Chromobacterium subtsugae competition in a dual-species model

bioRxiv, 2022
Many saprophytic bacteria have LuxR-I-type acyl-homoserine lactone (AHL) quorum-sensing systems that may be important for competing with other bacteria in complex soil communities.

Targeting Agrobacterium tumefaciens: A Computational Study on Quorum Sensing Inhibition

Journal of Basic Microbiology, Volume 65, Issue 7, July 2025.
ABSTRACT Crown gall disease, caused by Agrobacterium tumefaciens, results in significant loss in agricultural productivity losses due to induced tumor‐like growths on various crops. The virulence of A. tumefaciens is controlled by its quorum sensing (QS) system, specifically through the TraR protein, which regulates the expression of genes essential ...

Quorum Sensing: A Prospective Therapeutic Target for Bacterial Diseases

BioMed Research International, Volume 2019, Issue 1, 2019., 2019
Bacterial quorum sensing (QS) is a cell‐to‐cell communication in which specific signals are activated to coordinate pathogenic behaviors and help bacteria acclimatize to the disadvantages. The QS signals in the bacteria mainly consist of acyl‐homoserine lactone, autoinducing peptide, and autoinducer‐2. QS signaling activation and biofilm formation lead
