Characterization of the Erwinia chrysanthemi expI-expR locus directing the synthesis of two N-acyl-homoserine lactone signal molecules

, 1998
International audienceThe plant pathogen Erwinia chrysanthemi produces three acyl-homoserine lactones (acyl-HSLs). One has been identified as N-(3-oxohexanoyl)-homoserine lactone (OHHL), and the two others were supposed to be N-(hexanoyl)-homoserine ...

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.

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.

The GCR1 and GPA1 Participate in Promotion of Arabidopsis Primary Root Elongation Induced by N-Acyl-Homoserine Lactones, the Bacterial Quorum-Sensing Signals

Molecular Plant-Microbe Interactions, 2012
Many gram-negative bacteria use N-acyl-homoserine lactones (AHL) as quorum-sensing signals to coordinate their collective behaviors. Accumulating evidence indicates that plants can respond to AHL. However, little is known about the molecular mechanism of

Bacterial response to siderophore and quorum-sensing chemical signals in the seawater microbial community

BMC Microbiology, 2001
Background Oceans are iron-deficient and nutrient-poor environments. These conditions impart limitations on our understanding of and our ability to identify microorganisms from the marine environment.

A Variant Quorum Sensing System in Aeromonas veronii MTCC 3249

Sensors, 2012
We have investigated the quorum sensing control in Aeromonas veronii MTCC 3249, originally isolated as A. culicicola from the midgut of Culex quinquefasciatus.

Accurate mass analysis of N-acyl-homoserine-lactones and cognate lactone-opened compounds in bacterial isolates of Pseudomonas aeruginosa PAO1 by LC-ESI-LTQ-FTICR-MS

, 2009
N-acyl-homoserine-lactones (AHSLs) are widely conserved signal molecules present in quorum sensing systems of Gramnegative bacteria such as Pseudomonas aeruginosa.

Reversible acyl-homoserine lactone binding to purified Vibrio fischeri LuxR protein

, 2004
The Vibrio fischeri LuxR protein is the founding member of a family of acyl-homoserine lactone-responsive quorum-sensing transcription factors. Previous genetic evidence indicates that in the presence of its quorum-sensing signal, N-(3-oxohexanoyl ...

Acyl-homoserine lactones from Erwinia psidii R. IBSBF 435(T), a guava phytopathogen (Psidium guajava L.)

, 2015
The phytopathogen Erwinia psidii R. IBSBF 435(T) causes rot in branches, flowers, and fruits of guava (Psidium guajava L.), being responsible for crop losses, and has no effective control. It was demonstrated that this strain produces two compounds [S-(-)

The Ti plasmid of Agrobactetium tumefaciens harbors an attM-paralogous gene, aiiB, also encoding N-acyl homoserine lactonase activity

, 2003
The Agrobacterium tumefaciens C58 genome contains three putative N-acyl homoserine lactone (acyl-HSL) hydrolases, which are closely related to the lactonase AiiA of Bacillus.
