A Model of the Quorum Sensing System in Vibrio fischeri Using P Systems [PDF]

open access: yes, 2008
Quorum sensing is a cell density dependent gene regulation system that allows an entire population of bacterial cells to communicate in order to regulate the expression of certain or specific genes in a coordinated way depending on the size of the ...

Pan‐Genomic and Phenotypic Characterisation of Petroleum Hydrocarbon Degradation by Pseudomonas Species

open access: yesEnvironmental Microbiology Reports, Volume 18, Issue 1, February 2026.
Pseudomonas is one of the most significant bacterial genus involved in the petroleum hydrocarbon bioremediation. Innovatively, through pan‐genomic analysis at the genus level, we found that different Pseudomonas strains have excellent complementarity at the nodes of the degradation pathway of petroleum hydrocarbons.

Synthesis and biological evaluation of novel N-α-haloacylated homoserine lactones as quorum sensing modulators [PDF]

open access: yes, 2014
Novel N-α-haloacylated homoserine lactones, in which a halogen atom was introduced at the α-position of the carbonyl function of the N-acyl chain, have been studied as quorum sensing (QS) modulators and compared with a library of natural N-acylated ...

A short peptide derived from late embryogenesis abundant proteins enhances acid tolerance in Escherichia coli via modulation of two‐component regulatory systems

open access: yesThe FEBS Journal, Volume 293, Issue 3, Page 781-805, February 2026.
Expression of the LEA‐K peptide in E. coli BL21 (DE3) improved bacterial viability under acidic stress (pH4), suggesting a protective function. RNA‐sequencing of LEA‐K‐expressing vs. non‐expressing cells revealed 283 differentially expressed genes (DEGs). In silico docking linked LEA‐K to two‐component systems (TCS) proteins (Rcs, BtsS/R, and EnvZ/OmpR)

Virulence Regulation and Lifestyle Transitions: The Role of c‐di‐GMP and Two‐Component Systems in Erwinia amylovora and Their Evolutionary Context Within Enterobacterales

open access: yesMolecular Plant Pathology, Volume 27, Issue 2, February 2026.
Erwinia amylovora infects apple blossoms by activating the T3SS, then spreads systemically via amylovoran‐mediated biofilms. Transitions between motile and sessile states are regulated by key two‐component systems and c‐di‐GMP. This review summarises infection biology, virulence factors, regulatory networks and evolutionary insights underlying fire ...

A synthetic Escherichia coli predator–prey ecosystem [PDF]

open access: yes, 2008
We have constructed a synthetic ecosystem consisting of two Escherichia coli populations, which communicate bi-directionally through quorum sensing and regulate each other's gene expression and survival via engineered gene circuits.

An Evolving Perspective on the Pseudomonas aeruginosa Orphan Quorum Sensing Regulator QscR

open access: yesFrontiers in Cellular and Infection Microbiology, 2014
Many Proteobacteria govern responses to changes in cell density by using acyl-homoserine lactone (AHL) quorum-sensing (QS) signaling. Similar to the LuxI-LuxR system described in Vibrio fischeri, a minimal AHL QS circuit comprises a pair of genes, a luxI-

Emerging Threat of Vibrio alginolyticus in Mediterranean Aquaculture: Virulence, Antibiotic Resistance, and Innovative Control Strategies

open access: yesAquaculture Research, Volume 2026, Issue 1, 2026.
Vibrio alginolyticus is an opportunistic marine pathogen increasingly associated with disease outbreaks in Mediterranean aquaculture, affecting fish, shrimp, and shellfish. The semi‐enclosed nature of the Mediterranean Sea, combined with rising seawater temperatures and intensive farming practices, creates favorable conditions for the persistence and ...

Quantum Spin Formulation of the Principal Chiral Model [PDF]

open access: yes, 2000
We formulate the two-dimensional principal chiral model as a quantum spin model, replacing the classical fields by quantum operators acting in a Hilbert space, and introducing an additional, Euclidean time dimension.

2-Substituted Aniline as a Simple Scaffold for LuxR-Regulated QS Modulation

open access: yesMolecules, 2017
The ability of the 2-substituted aniline motif to serve as a scaffold for designing potential LuxR-regulated quorum sensing (QS) modulators has been investigated, using docking experiments and biological evaluation of a series of 15 specially synthesized
