Priming winter wheat seeds with the bacterial quorum sensing signal N-hexanoyl-L-homoserine lactone (C6-HSL) shows potential to improve plant growth and seed yield. [PDF]

PLoS ONE, 2019
Several model plants are known to respond to bacterial quorum sensing molecules with altered root growth and gene expression patterns and induced resistance to plant pathogens.

Effects on LuxR-Regulated Bioluminescence of Cyclodextrin-Acyl-L-Homoserine Lactone Hybrids. [PDF]

Chembiochem
Cyclodextrin‐N‐acyl‐L‐Homoserine‐Lactone conjugates are synthetized, purified and fully characterized. The study of modulation of LuxR‐regulated bioluminescence production has demonstrated that one of the compounds exhibits not only the capacity to induce bioluminescence with an EC50 value of 64 µM, but also the ability to reduce bioluminescence with ...

A Novel Screening System to Characterize and Engineer Quorum Quenching Lactonases. [PDF]

Biotechnol Bioeng
A new medium‐throughput screening system for identifying and characterizing N‐acyl L‐homoserine lactonases (AHLs), which hydrolyze bacterial communication signals and interfere With quorum sensing, was developed using N‐acyl L‐homocysteine thiolactones as chromogenic analogues.

Phenazine-1-Carboxamide Production in the Biocontrol Strain Pseudomonas chlororaphis PCL1391 Is Regulated by Multiple Factors Secreted into the Growth Medium [PDF]

Molecular Plant-Microbe Interactions, 2001
Pseudomonas chlororaphis PCL1391 controls tomato foot and root rot caused by Fusarium oxysporum f. sp. radicislycopersici. The production of phenazine-1-carboxamide (PCN) is crucial for this biocontrol activity.

Characterisation of a Marine Bacterium Vibrio Brasiliensis T33 Producing N-acyl Homoserine Lactone Quorum Sensing Molecules

Sensors, 2014
N-acylhomoserine lactones (AHL) plays roles as signal molecules in quorum sensing (QS) in most Gram-negative bacteria. QS regulates various physiological activities in relation with population density and concentration of signal molecules. With the aim

Engineering quorum quenching acylases with improved kinetic and biochemical properties. [PDF]

Protein Sci
Abstract Many Gram‐negative bacteria use N‐acyl‐L‐homoserine lactone (AHL) signals to coordinate phenotypes such as biofilm formation and virulence factor production. Quorum‐quenching enzymes, such as AHL acylases, chemically degrade these molecules which prevents signal reception by bacteria and inhibits undesirable biofilm‐related traits.

Heterologous production of rhamnolipids in Pseudomonas chlororaphis subsp chlororaphis ATCC 9446 based on the endogenous production of N-acyl-homoserine lactones. [PDF]

Microb Biotechnol
The heterologous production of the biosurfactant rhamnolipids in Pseudomonas chlororaphis ATCC 9446 was attained by the expression of the P. aeruginosa genes coding for the RhlA, RhlB, and RhlC enzymes involved in their synthesis. The P. aeruginosa quorum sensing transcriptional regulator RhlR coupled with acylhomoserine lactones endogenous produced by
