Exposure to static magnetic field stimulates quorum sensing circuit in luminescent Vibrio strains of the Harveyi clade. [PDF]
PLoS ONE, 2014 In this study, the evidence of electron-dense magnetic inclusions with polyhedral shape in the cytoplasm of Harveyi clade Vibrio strain PS1, a bioluminescent bacterium living in symbiosis with marine organisms, led us to investigate the behavior of this ...

A Mutational Analysis Defines Vibrio fischeri LuxR Binding Sites [PDF]
Journal of Bacteriology, 2008 ABSTRACT Vibrio fischeri quorum sensing involves the LuxI and LuxR proteins. The LuxI protein generates the quorum-sensing signal N -3-oxohexanoyl- l -homoserine lactone (3OC6-HSL), and LuxR is a signal-responsive transcriptional regulator which activates the ...

Directed evolution of Vibrio fischeri LuxR for improved response to butanoyl-homoserine lactone [PDF]
, 2007 LuxR is the 3-oxohexanoyl-homoserine lactone (3OC6HSL) dependent transcriptional activator of the prototypical acyl-homoserine lactone (AHL) quorum sensing system of Vibrio fischeri.

Environmental Microbiology, Volume 28, Issue 5, May 2026.I propose a ‘genome‐first’ framework to collapse the phenotypic bottleneck in bioinput discovery. By integrating multi‐layered genome mining and reverse ecology, this paradigm enables the rational design of stable synthetic microbial communities for a data‐driven and sustainable agricultural bioeconomy.

mLife, Volume 5, Issue 2, Page 164-179, April 2026.Abstract Mycosporine‐like amino acids (MAAs) are natural sunscreens synthesized by a wide range of organisms. Although the induction of MAA production by ultraviolet radiation is well established, the signaling pathways involved and specific functions of MAAs under other stress conditions remain poorly understood.

Impact of luxR complementation on bioluminescene during long term culturing of Vibrio fischeri. [PDF]
, 2013 Relative bioluminescence output from the dark V. fischeri MJ1 Lineage 10 with a luxR mutation complimented with a functional luxR gene under control of its own promoter on pLS6luxR.

Scientific Reports, 2017 LuxI and LuxR are key factors that drive quorum sensing (QS) in bacteria through secretion and perception of the signaling molecules e.g. N-Acyl homoserine lactones (AHLs).

Environmental Microbiology, Volume 28, Issue 4, April 2026.In this cultivation‐based study, two novel moderately thermophilic Nitrospira enrichments were obtained from the geothermal field Las Máquinas in the Neuquén Province, Argentina. Both nitrite oxidizers, belonging to lineage V or the novel taxonomic lineage VIII, contain quorum‐sensing genes and a high genome GC content of 60.6% and 69.4%.

RpoE controls Asp expression via the QS regulator LuxR. [PDF]
, 2016 (A) luxR transcriptional assays were performed in wt and ΔluxO strains that were grown at different temperatures. The wt and ΔluxO strains that carried the PluxR-lacZ reporter plasmid were cultured in LBS medium and assayed for β-galactosidase activity ...
