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

Contribution of a Novel TetR/AcrR Family Transcriptional Regulator RalT of Ralstonia pseudosolanacearum Strain OE1‐1 to the Fine‐Tuning of Its Virulence

MicrobiologyOpen, Volume 15, Issue 1, February 2026.
Predicted regulation of quorum sensing‐, ralfuranone‐, and RalT‐dependent genes (QS/Ral/p0599‐dependent genes) via a novel TetR/AcrR family transcriptional regulator RalT in Ralstonia pseudosolanacearum strain OE1‐1 was shown here. The regulation of ralT is dependent on ralfuranone, and contribution of RalT is popular with the regulation of some quorum

An Unprecedented Medium-Chain Diunsaturated N-acylhomoserine Lactone from Marine Roseobacter Group Bacteria

Marine Drugs, 2018
N-acylhomoserine lactones (AHLs), bacterial signaling compounds involved in quorum-sensing, are a structurally diverse group of compounds. We describe here the identification, synthesis, occurrence and biological activity of a new AHL, N-((2E,5Z)-2,5 ...

Global Warming Affects the Pathogenesis of Important Fish Diseases in European Aquaculture

Reviews in Aquaculture, Volume 18, Issue 1, January 2026.
The effect of global warming on pathogens and their fish hosts that could exacerbate the negative outcomes for aquaculture. Changes in farming practices and the development of innovative mitigation tools may prove essential to cope with the effects and impacts of rising water temperatures on fish diseases in Europe.

Antibacterial Activities of Selected Pure Compounds Isolated from Gut Bacteria of Animals Living in Polluted Environments

Antibiotics, 2020
Antibiotic resistance is a global threat to public health, further accelerated by the misuse of antibiotics in humans and animals. Our recent studies have shown that gut bacteria of animals living in polluted environments are a potential source of ...

Endocrine‐Taste Crosstalk: A Scoping Review on Thyroid Dysfunction and Its Genetic Links to Taste Receptors With Dysgeusia

International Journal of Endocrinology, Volume 2026, Issue 1, 2026.
Thyroid disorders are a common endocrine condition globally, affecting various bodily systems and metabolism. Changes in thyroid function affect smell and taste; yet, many patients remain unaware of their dysosmia and dysgeusia. Currently, there is a lack of detailed information regarding changes in physiological taste thresholds across different taste

Selection of a new Pseudomonas chlororaphis strain for the biological control of Fusarium oxysporum f. sp. radicis-lycopersici

Phytopathologia Mediterranea, 2011
Fluorescent pseudomonads possess several physiological characteristics exploitable for the biological control of phytopathogenic fungi. A group of 11 pseudomonads able to inhibit tomato pathogenic fungi in vitro were identified using the Biolog test and ...

High yield expression of an AHL-lactonase from Bacillus sp. B546 in Pichia pastoris and its application to reduce Aeromonas hydrophila mortality in aquaculture [PDF]

, 2010
Background Aeromonas hydrophila is a serious pathogen and can cause hemorrhagic septicemia in fish. To control this disease, antibiotics and chemicals are widely used which can consequently result in "superbugs" and chemical accumulation in the food ...

A Rhodococcal Transcriptional Regulatory Mechanism Detects the Common Lactone Ring of AHL Quorum-Sensing Signals and Triggers the Quorum-Quenching Response

Frontiers in Microbiology, 2018
The biocontrol agent Rhodococcus erythropolis disrupts virulence of plant and human Gram-negative pathogens by catabolizing their N-acyl-homoserine lactones.
