Pseudomonas cyclic lipopeptides suppress the rice blast fungus Magnaporthe oryzae by induced resistance and direct antagonism [PDF]
, 2019 Beneficial Pseudomonas spp. produce an array of antimicrobial secondary metabolites such as cyclic lipopeptides (CLPs). We investigated the capacity of CLP-producing Pseudomonas strains and their crude CLP extracts to control rice blast caused by ...

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

Deciphering the Symbiotic Significance of Quorum Sensing Systems of Sinorhizobium fredii HH103 [PDF]
, 2020 Quorum sensing (QS) is a bacterial cell-to-cell signaling mechanism that collectively regulates and synchronizes behaviors by means of small diffusible chemical molecules.

Journal of Biological Chemistry, 1992 The LuxR protein is a transcriptional activator involved in regulation of the genes required for bioluminescence (lux) in the marine bacterium Vibrio fischeri. Transcription of the two divergently oriented lux operons (luxR and luxICDABEG) is activated by LuxR in the presence of a diffusible inducer (autoinducer).

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 ...

Specific quorum sensing-disrupting activity (A(QSI)) of thiophenones and their therapeutic potential [PDF]
, 2015 Disease caused by antibiotic resistant pathogens is becoming a serious problem, both in human and veterinary medicine. The inhibition of quorum sensing, bacterial cell-to-cell communication, is a promising alternative strategy to control disease. In this

A σE-Mediated Temperature Gauge Controls a Switch from LuxR-Mediated Virulence Gene Expression to Thermal Stress Adaptation in Vibrio alginolyticus. [PDF]
PLoS Pathogens, 2016 In vibrios, the expression of virulence factors is often controlled by LuxR, the master quorum-sensing regulator. Here, we investigate the interplay between LuxR and σE, an alternative sigma factor, during the control of virulence-related gene expression

Bacterial Subfamily of LuxR Regulators That Respond to Plant Compounds [PDF]
Applied and Environmental Microbiology, 2011 ABSTRACT Pseudomonas fluorescens are rhizobacteria known for their biocontrol properties. Several antimicrobial functions are crucial for this process, and the experiments described here investigate the modulation of their expression during the plant-bacterium interaction.

Microorganisms, 2023 In bacteria, group-coordinated behavior such as biofilm formation or virulence are often mediated via cell–cell communication, a process referred to as quorum sensing (QS). The canonical QS system of Gram-negative bacteria uses N-acyl homoserine lactones
