Census of solo LuxR genes in prokaryotic genomes [PDF]
Frontiers in Cellular and Infection Microbiology, 2015 luxR genes encode transcriptional regulators that control acyl homoserine lactone-based quorum sensing (AHL QS) in Gram negative bacteria. On the bacterial chromosome, luxR genes are usually found next or near to a luxI gene encoding the AHL signal ...

LuxR solos in Photorhabdus species [PDF]
Frontiers in Cellular and Infection Microbiology, 2014 Bacteria communicate via small diffusible molecules to mediate group-coordinated behavior, a process designated as quorum sensing. The basic molecular quorum sensing system of Gram-negative bacteria consists of a LuxI-type autoinducer synthase producing ...

LuxR Solos from Environmental Fluorescent Pseudomonads
mSphere, 2021 LuxR solos are related to quorum sensing (QS) LuxR family regulators; however, they lack a cognate LuxI family protein. LuxR solos are widespread and almost exclusively found in proteobacteria.

A walk into the luxR regulators of actinobacteria : phylogenomic distribution and functional diversity [PDF]
PLoS ONE, 2012 LuxR regulators are a widely studied group of bacterial helix-turn-helix (HTH) transcription factors involved in the regulation of many genes coding for important traits at an ecological and medical level.

MSystems, 2023 Many proteobacteria possess LuxR solos which are quorum sensing LuxR-type regulators that are not paired with a cognate LuxI-type synthase. LuxR solos have been implicated in intraspecies, interspecies, and interkingdom communication by sensing ...

Dual selection enhances the signaling specificity of a variant of the quorum-sensing transcriptional activator LuxR [PDF]
Nature Biotechnology, 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.

Frontiers in Cellular and Infection Microbiology, 2015 LuxR solo transcriptional regulators contain both an autoinducer binding domain (ABD; N-terminal) and a DNA binding Helix-Turn-Helix domain (HTH; C-terminal), but are not associated with a cognate N-acyl homoserine lactone (AHL) synthase coding gene in ...

Quorum-sensing regulates biofilm formation in Vibrio scophthalmi [PDF]
BMC Microbiology, 2013 Background: In a previous study, we demonstrated that Vibrio scophthalmi, the most abundant Vibrio species among the marine aerobic or facultatively anaerobic bacteria inhabiting the intestinal tract of healthy cultured turbot (Scophthalmus maximus ...

Bacterial LuxR solos have evolved to respond to different molecules including signals from plants
Frontiers in Plant Science, 2013 A future challenge will be understanding the extensive communication that most likely takes place in bacterial interspecies and interkingdom signaling between plants and bacteria.

Stenotrophomonas maltophilia responds to exogenous AHL signals through the LuxR solo SmoR (Smlt1839)
Frontiers in Cellular and Infection Microbiology, 2015 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
