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]).

Biogenic Synthesis of ZnO Nanoparticles From Heliotropium europaeum and Assessment of Antibiofilm, Anti‐Quorum‐Sensing, Antioxidant and Anticholinesterase Activities

Natural Sciences, Volume 6, Issue 2, April 2026.
Synthesis, characterization and biological activities of ZnO nanoparticles. ABSTRACT Zinc oxide nanoparticles (ZnO‐NPs) are inexpensive, non‐toxic, and biocompatible with human cells, making them suitable for biomedical applications. In the present study, ZnO‐NPs were synthesized from Heliotropium europaeum extracts at different concentrations through ...

Quorum Sensing and Expression of Virulence in Pectobacteria

Sensors, 2012
Quorum sensing (QS) is a population density-dependent regulatory mechanism in which gene expression is coupled to the accumulation of a chemical signaling molecule. QS systems are widespread among the plant soft-rotting bacteria.

Metagenomic and Phenotypic Insights Into Biofilm‐Forming Pathogens in Patients With Nosocomial Sepsis

BioMed Research International, Volume 2026, Issue 1, 2026.
Biofilm‐related infections significantly contribute to bacterial diseases, with estimates suggesting that at least 80% of such infections are associated with biofilms. These infections often involve opportunistic pathogens, which not only influence the type of infection but also impact the microenvironment by interacting with other polymicrobial ...
