LuxR Solos are Becoming Major Players in Cell-Cell Communication in Bacteria [PDF]
, 2016 The most common quorum sensing (QS) system in Gram-negative bacteria occurs via N-acyl homoserine lactone (AHLs) signals. An archetypical system consists of a LuxI-family protein synthesizing the AHL signal which binds at quorum concentrations to the ...

LuxR induction in solid agar cultures. [PDF]
, 2018 The leftmost image shows the layout used to determine induction distance across agar. Sender bacteria were spotted in the center. Bacteria transformed with Control-EGFP (GFP), receiver negative (NR), or LuxR receiver (R) plasmids were spotted within ...

Dual selection enhances the signaling specificity of a variant of the quorum-sensing transcriptional activator LuxR [PDF]
, 2006 The transcription factor LuxR activates gene expression in response to binding the signaling molecule 3-oxo-hexanoyl-homoserine lactone (3OC6HSL), an acyl-HSL with a carbonyl substituent at the third carbon of the acyl chain.

PpoR is a conserved unpaired LuxR solo of
BMC Microbiology, 2009 Background 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.

XocR, a LuxR solo required for virulence in Xanthomonas oryzae pv. oryzicola
Frontiers in Cellular and Infection Microbiology, 2015 Xanthomonas oryzae pv. oryzicola (Xoc) causes bacterial leaf streak (BLS) in rice, a serious bacterial disease of rice in Asia and parts of Africa. The virulence mechanisms of Xoc are not entirely clear and control measures for BLS are poorly developed ...

Analysis of the Regulons Controlled by Transcriptional Regulators LuxR and LitR in Vibrio fischeri [PDF]
, 2008 Quorum sensing is a bacterial signaling system that controls gene expression in a population density-dependent manner. In Gram-negative proteobacteria, the cell density control of luminescence was first observed in the symbiotic marine bacterium Vibrio ...

Stenotrophomonas maltophilia responds to exogenous AHL signals through the LuxR solo SmoR (Smlt1839) [PDF]
, 2021 Quorum Sensing (QS) mediated by Acyl Homoserine Lactone (AHL) molecules are probably the most widespread and studied among Gram-negative bacteria. Canonical AHL systems are composed by a synthase (LuxI family) and a regulator element (LuxR family), whose

Chemical probes to control a dissociative LuxR-type quorum sensing receptor in Gram-negative bacteria [PDF]
Quorum sensing (QS) allows bacteria to respond to changes in cell density and participate in collective behaviors. Interfering in QS could provide a strategy to block pathogenicity, reduce biofouling, and support biotechnology.
