Identification and characterization of LuxR solo homolog PplR in pathogenic Pseudomonas plecoglossicida NB2011. [PDF]

Front Cell Infect Microbiol
Pseudomonas plecoglossicida is a causative agent of visceral granulomas in large yellow croaker (Larimichthys crocea). Quorum sensing (QS) is widely involved in imparting virulence to pathogenic bacteria; however, it has not been studied in P. plecoglossicida. In this study, we annotated a LuxR family transcriptional regulator in P.

Extracellular vesicles as structured vectors of quorum sensing signals influence aquatic microbial communities [PDF]

npj Biofilms and Microbiomes
Quorum sensing (QS) orchestrates collective microbial behaviors and functional acclimatization through chemical communication. However, QS in natural waters is challenged by dilution, alkaline hydrolysis, and enzymatic degradation of freely dissolved ...

LuxR-family ‘solos’: bachelor sensors/regulators of signalling molecules [PDF]

Microbiology, 2009
N-Acylhomoserine lactone (AHL) quorum-sensing (QS) signalling is the best-understood chemical language in proteobacteria. In the last 15 years a large amount of research in several bacterial species has revealed in detail the genetic, molecular and biochemical mechanisms underlying AHL signalling. These studies have revealed the role

Roles of a Solo LuxR in the Biological Control Agent Lysobacter enzymogenes Strain OH11 [PDF]

Phytopathology®, 2014
Lysobacter enzymogenes is a ubiquitous plant-associated and environmentally friendly bacterium emerging as a novel biological control agent of plant disease. This bacterium produces diverse antifungal factors, such as lytic enzymes and a secondary metabolite (heat-stable antifungal factor [HSAF]) having antifungal activity with a novel structure and ...

Whole genome sequencing and analysis reveal insights into the genetic structure, diversity and evolutionary relatedness of luxI and luxR homologs in bacteria belonging to the Sphingomonadaceae family

Frontiers in Cellular and Infection Microbiology, 2015
Here we report the draft genomes and annotation of four N-acyl homoserine lactone (AHL)-producing members from the family Sphingomonadacae. Comparative genomic analyses of 62 Sphingomonadacae genomes were performed to gain insights into the distribution

PpoR is a conserved unpaired LuxR solo of Pseudomonas putida which binds N-acyl homoserine lactones [PDF]

BMC Microbiology, 2009
Only a small number of Pseudomonas putida strains possess the typical N-acyl homoserine lactone quorum sensing system (AHL QS) that consists of a modular LuxR family protein and its cognate LuxI homolog that produces the AHL signal. Moreover, AHL QS systems in P.

Host-specific signal perception by PsaR2 LuxR solo induces Pseudomonas syringae pv. actinidiae virulence traits

Microbiological Research, 2022
Plant-associated bacteria, including pathogens, recognise host-derived signals to activate specific responses. The genome of Pseudomonas syringae pv. actinidiae (Psa), the aetiological agent of bacterial canker of kiwifruit, encodes for three putative LuxR-like receptors.

Membrane composition and thermodynamic identity as boundaries of life for synthetic cell research

FEBS Letters, Volume 600, Issue 20, Page 2981-3008, October 2026.
What makes a cell a cell? The boundary of a living cell is not just a wall. Read as a Markov blanket, the membrane separates internal from external states, generating identity and non‐equilibrium order. Can this identity be rebuilt from scratch in a synthetic cell?
