Regulation of acylated homoserine lactones (AHLs) in beef by spice marination [PDF]

Journal of Food Science and Technology, 2016
Quorum sensing (QS) is a signaling mechanism used by bacteria to communicate each other through the release of auto-inducing signaling molecules. Despite the fact that bacteria regulate its phenotypes by QS mechanism, their potential role in meat spoilage is not yet elucidated.

Molecular Mechanisms of Algicidal Bacteria in Controlling Harmful Algal Blooms: Advances in Bacteria‐Algae Interactions

Environmental Microbiology Reports, Volume 18, Issue 2, April 2026.
This review elucidates the molecular mechanisms of algicidal bacteria, highlighting critical behaviours like chemotaxis, quorum sensing and extracellular vesicle release. It details how these actions disrupt algal cellular integrity, photosynthesis and calcium homeostasis, providing a theoretical foundation for controlling harmful algal blooms ...

Evolution of acyl-substrate recognition by a family of acyl-homoserine lactone synthases. [PDF]

PLoS ONE, 2014
Members of the LuxI protein family catalyze synthesis of acyl-homoserine lactone (acyl-HSL) quorum sensing signals from S-adenosyl-L-methionine and an acyl thioester.

Joining the bacterial conversation: increasing the cultivation efficiency of soil bacteria with acyl-homoserine lactones and cAMP

Microbiology Spectrum, 2023
Bacteria need to be isolated in pure culture to gain access to the wide array of interesting functions they conceal. This is challenging because they do not live in isolation but instead in communities where they actively communicate and interact with ...

Analysis of Bacterial Wilt Management Strategies From the Dynamic Perspective of Environmental Adaptation Approaches of Ralstonia solanacearum

Environmental Microbiology Reports, Volume 18, Issue 2, April 2026.
This review reframes bacterial wilt management by analysing control strategies through the lens of the pathogen's evolutionary, physiological and ecological adaptations. This mechanism‐based approach links pathogen traits to control efficacy, guiding the development of more durable solutions.

A Sinorhizobium meliloti-specific N-acyl homoserine lactone quorum-sensing signal increases nodule numbers in Medicago truncatula independent of autoregulation

Frontiers in Plant Science, 2014
N-acyl homoserine lactones (AHLs) act as quorum sensing signals that regulate cell-density dependent behaviors in many gram-negative bacteria, in particular those important for plant-microbe interactions.

The MarR Family Transcriptional Regulator EmrR Negatively Regulates the Type III Secretion System (T3SS) and Positively Modulates Pathogenicity in Dickeya oryzae

Molecular Plant Pathology, Volume 27, Issue 4, April 2026.
This study revealed that the transcriptional regulator EmrR in Dickeya oryzae modulates virulence by regulating hrpL expression and c‐di‐GMP levels. It affects motility, biofilm formation, cellulase production and pathogenicity. EMSA and footprinting confirmed EmrR binds directly to the promoter of its target operon.

Unravelling the genome of long chain N-acylhomoserine lactone-producing Acinetobacter sp. strain GG2 and identification of its quorum sensing synthase gene

Frontiers in Microbiology, 2015
Myriad proteobacteria use N-acyl homoserine lactone (AHL) molecules as quorum-sensing (QS) signals to regulate different physiological functions, including virulence, antibiotic production and biofilm formation.

Programming Next‐Generation Synthetic Biosensors by Genetic Circuit Design

Advanced Science, Volume 13, Issue 14, 9 March 2026.
Synthetic biology enables genetic circuit‐based biosensing to detect diverse targets, process signals, and transduce them into readable outputs or intracellular regulatory activities. However, field deployment and real‐world application of such synthetic biosensors face considerable challenges in sensitivity, specificity, speed, stability, and ...
