Phloretin, an Apple Phytoalexin, Affects the Virulence and Fitness of Pectobacterium brasiliense by Interfering With Quorum-Sensing

Frontiers in Plant Science, 2021
The effects of phloretin a phytoalexin from apple, was tested on Pectobacterium brasiliense (Pb1692), an emerging soft-rot pathogen of potato. Exposure of Pb1692 to 0.2 mM phloretin a concentration that does not affect growth, or to 0.4 mM a 50% growth ...

CerM and Its Antagonist CerN Are New Components of the Quorum Sensing System in Cereibacter sphaeroides, Signaling to the CckA/ChpT/CtrA System

MicrobiologyOpen, Volume 13, Issue 6, December 2024.
The quorum sensing (QS) system of Cereibacter sphaeroides includes six LuxR homologs and one acylhomoserine lactone synthase homolog. Two LuxR homologs, CerM and CerN, are involved in regulating the expression of ctrA, which is part of the CckA/ChpT/CtrA two‐component system that controls flagellar motility.

Exploring Naturally Tailored Bacterial Outer Membrane Vesicles for Selective Bacteriostatic Implant Coatings

Advanced Science, Volume 11, Issue 39, October 23, 2024.
Bacterial outer membrane vesicles (OMVs) are now used to construct implant coatings, showing unexpected selective bacteriostasis at the macroscopic level. Using a simple polyphenol bridging technology stabilizes bacterial OMVs on various implant surfaces. This OMVs coating gives implants the ability to selectively inhibit bacteria. This method provides

From trade‐off to synergy: microbial insights into enhancing plant growth and immunity

Plant Biotechnology Journal, Volume 22, Issue 9, Page 2461-2471, September 2024.
Summary The reduction in crop yield caused by pathogens and pests presents a significant challenge to global food security. Genetic engineering, which aims to bolster plant defence mechanisms, emerges as a cost‐effective solution for disease control. However, this approach often incurs a growth penalty, known as the growth‐defence trade‐off.

Dialogues of root-colonizing biocontrol pseudomonads [PDF]

, 2018
Among biocontrol agents that are able to suppress root diseases caused by fungal pathogens, root-colonizing fluorescent pseudomonads have received particular attention because many strains of these bacteria trigger systemic resistance in host plants and ...

Microfluidics-based liquid chromatography/mass spectrometry multiple reaction monitoring approach for the relative quantification of Burkholderia cenocepacia secreted virulence factors [PDF]

, 2018
Rationale: Burkholderia cenocepacia is an opportunistic pathogen that is commonly isolated from patients with cystic fibrosis (CF). Quorum sensing has been suggested to play a role in the activity of type II and type VI secretion systems and the release ...

Isolation and identification of N-acylhomoserin lactone degrading bacteria from potato rhizosphere

African Journal of Microbiology Research, 2011
In many Gram-negative bacteria, including a number of pathogens such asPectobacterium carotovorum, virulence factor production and many functions are linked to the quorum sensing (QS) systems that use diffusible N-acyl homoserine lactones (AHLs) as intercellular messenger molecules.

Flavonoids, gut microbiota, and host lipid metabolism

Engineering in Life Sciences, Volume 24, Issue 5, May 2024.
Abstract Flavonoids are widely distributed in nature and have a variety of beneficial biological effects, including antioxidant, anti‐inflammatory, and anti‐obesity effects. All of these are related to gut microbiota, and flavonoids also serve as a bridge between the host and gut microbiota. Flavonoids are commonly used to modify the composition of the

Characterisation of two quorum sensing systems in the endophytic Serratia plymuthica strain G3: differential control of motility and biofilm formation according to life-style

BMC Microbiology, 2011
Background N-acylhomoserine lactone (AHL)-based quorum sensing (QS) systems have been described in many plant-associated Gram-negative bacteria to control certain beneficial phenotypic traits, such as production of biocontrol factors and plant growth ...

Degradation of N-Acylhomoserine Lactone Quorum Sensing Signaling Molecules by Potato Root Surface-Associated Chryseobacterium Strains

Microbes and Environments, 2011
N-Acylhomoserine lactones (AHLs) are used as quorum-sensing signaling molecules by many Gram-negative bacteria. Here, 413 bacterial strains were obtained from the roots of potato plants and screened for AHL-degrading bacteria using Chromobacterium violaceum reporter strains. Sixty one isolates degraded N-hexanoyl-L-homoserine lactone (C6-HSL) within 24
