Identification, synthesis and regulatory function of the N-acylated homoserine lactone signals produced by Pseudomonas chlororaphis HT66

Microbial Cell Factories, 2018
Background Pseudomonas chlororaphis HT66 isolated from the rice rhizosphere is an important plant growth-promoting rhizobacteria that produce phenazine-1-carboxamide (PCN) in high yield.

Impeding Quorum Sensing Among the Intestinal Microbiota Impacts the Metastatic Rate of Colorectal Cancer

Cancer Medicine, Volume 14, Issue 12, June 2025.
ABSTRACT Background The gut microbiota is associated with colorectal cancer (CRC) risk and CRC metastatic potential. However, the role of bacteria in CRC progression and metastasis remains unclear. Aims Here, we hypothesized that microbial communication, mediated through quorum sensing (QS), was a critical component regulating microbial functions ...

Identification of Yunnan Guangnan Dendrobium officinale With Different Growth Years Using UHPLC–Orbitrap–MS

eFood, Volume 6, Issue 3, June 2025.
ABSTRACT Dendrobium officinale from Guangnan was screened nontargeted using UHPLC–Orbitrap‐MS for different growth years. OPLS‐DA effectively differentiated D. officinale based on growth years, identifying 70 different compounds. Eight indole diketopiperazine alkaloids did not differ considerably among the growth years. The differential compounds of D.

Positive Autoregulation of an Acyl-Homoserine Lactone Quorum-Sensing Circuit Synchronizes the Population Response

mBio, 2017
Many proteobacteria utilize acyl-homoserine lactone quorum-sensing signals. At low population densities, cells produce a basal level of signal, and when sufficient signal has accumulated in the surrounding environment, it binds to its receptor, and ...

Food Waste to Wellness: A Grape Pomace Blend in Gastric Cancer Prevention

Food Science &Nutrition, Volume 13, Issue 6, June 2025.
Grape pomace was used to set up a phytocomplex studied for gastric cancer prevention. HPLC/MS analyses revealed that this mixture is a source of many polyphenols and amino acids. This novel nutraceutical (GPE) selectively targets cancer cells, sparing healthy ones. Molecular mechanisms confirmed that GPE acts, inducing apoptosis and autophagy.

A Lrp/AsnC Family Transcriptional Regulator Lrp Is Essential for the Pathogenicity of Dickeya oryzae

Molecular Plant Pathology, Volume 26, Issue 6, June 2025.
Lrp is crucial for regulating the pathogenicity of Dickeya oryzae by forming a hierarchical regulatory network with other transcriptional regulatory factors and directly modulating the expression of virulence genes. ABSTRACT Dickeya oryzae causes severe soft rot diseases in a range of important crops. To understand its complicated pathogenic mechanisms,

Antimicrobial Resistance in Malaysian Shrimp Aquaculture and Strategies to Reduce Its Occurrence

Reviews in Aquaculture, Volume 17, Issue 3, June 2025.
ABSTRACT Shrimp is a commercially important species in several regions and is among the key global aquaculture commodities essential for food production and security. Similar to most shrimp‐producing countries, shrimp aquaculture in Malaysia suffers from recurring disease outbreaks that consequently impact the overall economy.

The RhlR quorum-sensing receptor controls Pseudomonas aeruginosa pathogenesis and biofilm development independently of its canonical homoserine lactone autoinducer.

PLoS Pathogens, 2017
Quorum sensing (QS) is a bacterial cell-to-cell communication process that relies on the production, release, and response to extracellular signaling molecules called autoinducers.

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
