Frequency modulation of a bacterial quorum sensing response

Nature Communications, 2022
Quorum-sensing bacteria produce and secrete autoinducers that trigger a behavioral change in the population when reaching a certain threshold. Here, Bettenworth et al.

PtrA is functionally intertwined with GacS in regulating the biocontrol activity of Pseudomonas chlororaphis PA23

Frontiers in Microbiology, 2016
In vitro inhibition of the fungal pathogen Sclerotinia sclerotiorum by Pseudomonas chlororaphis PA23 is reliant upon a LysR-type transcriptional regulator (LTTR) called PtrA. In the current study, we show that Sclerotinia stem rot and leaf infection are

Autoinducer [PDF]

, 2008
The pathogenic bacterium Pseudomonas aeruginosa utilizes the 3-oxododecanoyl homoserine lactone (3OC(12)-HSL) autoinducer as a signaling molecule to coordinate the expression of virulence genes through quorum sensing.

Black Queen Hypothesis, partial privatization, and quorum sensing evolution.

PLoS ONE, 2022
Microorganisms produce costly cooperative goods whose benefit is partially shared with nonproducers, called 'mixed' goods. The Black Queen Hypothesis predicts that partial privatization has two major evolutionary implications.

Production and properties of an inhibitor of the Pseudomonas autoinducer by Pseudomonas aeruginosa [PDF]

, 2005
An inhibitor was found in the culture fluid of Pseudomonas aeruginosa PAO1. which could inhibit the activity of the Pseudomonas autoinducer (PAI). The maximal inhibitory activity occurred in stationary phase culture supernatant. The PAI inhibitor did not

Regulation of autoinducer production in Salmonella typhimurium [PDF]

Molecular Microbiology, 1999
Salmonella typhimurium strain LT2 secretes an organic signalling molecule that can be assayed by its ability to activate one of two specific quorum‐sensing systems in Vibrio harveyi. Maximal activity is produced during mid‐ to late exponential phase when S. typhimurium is grown in the presence of glucose or other preferred carbohydrates. The signal is

Quorum Activation at a Distance: Spatiotemporal Patterns of Gene Regulation from Diffusion of an Autoinducer Signal [PDF]

, 2016
Quorum sensing (QS) bacteria regulate gene expression collectively by exchanging diffusible signal molecules known as autoinducers. Although QS is often studied in well-stirred laboratory cultures, QS bacteria colonize many physically and chemically ...

Detection of AI-2 Receptors in Genomes of <em>Enterobacteriaceae </em>Suggests a Role of Type-2 Quorum Sensing in Closed Ecosystems

Sensors, 2012
The LuxS enzyme, an S-ribosyl-homocysteine lyase, catalyzes the production of the signal precursor for autoinducer-2 mediated quorum sensing (QS-2) in <em>Vibrio</em>.
