Phloretin, an Apple Phytoalexin, Affects the Virulence and Fitness of Pectobacterium brasiliense by Interfering With Quorum-Sensing

Frontiers in Plant Science, 2021
The effects of phloretin a phytoalexin from apple, was tested on Pectobacterium brasiliense (Pb1692), an emerging soft-rot pathogen of potato. Exposure of Pb1692 to 0.2 mM phloretin a concentration that does not affect growth, or to 0.4 mM a 50% growth ...

Synthesis, Cytotoxic Activity, Antiquorum Sensing Effect, Docking and Md Simulation of Novel 1,3‐Disubstituted 2‐Mercapto‐1H‐Benzo[D]Imidazolium Chlorides

Journal of Biochemical and Molecular Toxicology, Volume 39, Issue 4, April 2025.
A series of benzimidazolium chlorides and their 2‐mercapto were successfully synthesized and characterized. Cytotoxic activity assays revealed that certain synthesized compounds exhibited efficacy against cancer cell lines. To investigate the possible mechanism underlying their cytotoxic effects, the binding interactions of the three most active ...

Quercetin Exhibits Broad‐Spectrum Antibiofilm and Antiquorum Sensing Activities Against Gram‐Negative Bacteria: In Vitro and In Silico Investigation Targeting Antimicrobial Therapy

Canadian Journal of Infectious Diseases and Medical Microbiology, Volume 2025, Issue 1, 2025.
Quercetin (QC), a flavonoid abundant in fruits and vegetables, has garnered attention for its potential therapeutic properties. In this study, we investigated the antibiofilm and antiquorum sensing (QS) activities of QC against Gram‐negative bacteria both in vitro and in silico.

Effect of sdiA on Biosensors of N -Acylhomoserine Lactones [PDF]

Journal of Bacteriology, 2005
ABSTRACT Many gram-negative bacteria synthesize N -acylhomoserine lactones (AHLs) and then use transcription factors of the LuxR family to sense and respond to AHL accumulation in the environment; this phenomenon is termed quorum sensing.

Characterisation of two quorum sensing systems in the endophytic Serratia plymuthica strain G3: differential control of motility and biofilm formation according to life-style

BMC Microbiology, 2011
Background N-acylhomoserine lactone (AHL)-based quorum sensing (QS) systems have been described in many plant-associated Gram-negative bacteria to control certain beneficial phenotypic traits, such as production of biocontrol factors and plant growth ...

Infant‐Type Bifidobacteria as Biocontrol Agents: Suppressing Listeria monocytogenes via Key Virulence Gene Alteration

Canadian Journal of Infectious Diseases and Medical Microbiology, Volume 2025, Issue 1, 2025.
Infant‐type bifidobacteria exhibit potential as targeted biocontrol agents against Listeria monocytogenes infections. However, the strain‐specific antimicrobial efficacy and molecular mechanisms remain insufficiently characterized. In this study, the probiotic potential of five bifidobacteria strains was systematically evaluated through comprehensive ...

CerM and Its Antagonist CerN Are New Components of the Quorum Sensing System in Cereibacter sphaeroides, Signaling to the CckA/ChpT/CtrA System

MicrobiologyOpen, Volume 13, Issue 6, December 2024.
The quorum sensing (QS) system of Cereibacter sphaeroides includes six LuxR homologs and one acylhomoserine lactone synthase homolog. Two LuxR homologs, CerM and CerN, are involved in regulating the expression of ctrA, which is part of the CckA/ChpT/CtrA two‐component system that controls flagellar motility.
