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.

Phenotypic expression of the gene‐for‐gene interaction in plant pathogenic bacteria: An implication for resistance to bacterial diseases by plants

Agrosystems, Geosciences &Environment, Volume 9, Issue 3, September 2026.
Abstract Plant pathogenic bacteria cause massive losses in agriculture and damage to natural plant habitats. Bacterial pathogens not only reduce crop production, but they also reduce crop quality by releasing toxins into the environment. Pathogenic bacteria that invade plant tissues must overcome the plant's defense mechanisms. Plants possess an innate

The role of microbial dormancy autoinducers in metabolism blockade

, 2020
Alkyl-substituted hydroxybenzenes (AHBs), which are autoinducers of microbial dormancy (d1 factors), were found to stabilize the structure of protein macromolecules and modify the catalytic activity of enzymes.

Cyclic Dipeptides Mediating Quorum Sensing and Their Biological Effects in Hypsizygus Marmoreus

Biomolecules, 2020
A novel quorum sensing (QS) system was discovered in Serratia odorifera, the symbiotic bacterium of Hypsizygus marmoreus. This system uses cyclo(Pro-Phe), cyclo(Pro-Tyr), cyclo(Pro-Val), cyclo(Pro-Leu), cyclo(Tyr-Leu), and cyclo(Tyr-Ile) as autoinducers.

Natural Lactone‐Based Quorum Sensing Inhibitors Attenuate Virulence in Pseudomonas aeruginosa

Chemistry &Biodiversity, Volume 23, Issue 9, September 2026.
Targeting bacterial communication, lab‐generated lactones (Lx) inhibited biofilm formation and eliminated mature biofilms within 24–48 h. Lx treatment also suppressed pyocyanin and rhamnolipid production while downregulating rhlR expression, highlighting their promise as potent quorum‐sensing (QS) inhibitors and next‐generation antibiofilm therapeutics.

Phage-Encoded LuxR-Type Receptors Responsive to Host-Produced Bacterial Quorum-Sensing Autoinducers

mBio, 2019
Quorum sensing (QS) is a process of cell-to-cell communication that bacteria use to orchestrate collective behaviors. QS relies on the cell-density-dependent production, accumulation, and receptor-mediated detection of extracellular signaling molecules ...

Microbiome‐mediated chemical communication in insects: Implications for pest management

Pest Management Science, Volume 82, Issue 9, Page 8132-8151, September 2026.
Microbiome–semiochemical interactions involve the following processes: direct microbial synthesis, host gene regulation, precursor biotransformation, microbiome modulation and indirect ecological signaling. Abstract Insects rely on semiochemicals to regulate aggregation, mating, foraging, and host selection. This review synthesizes evidence that insect‐

A Lytic Bacteriophage Cocktail Attenuates Carbapenem‐Resistant Klebsiella pneumoniae–Acinetobacter baumannii Mixed‐Species Biofilms and Reshapes Transcriptional Responses

Microbial Biotechnology, Volume 19, Issue 9, September 2026.
A lytic phage cocktail targeting CRKP–CRAB mixed biofilms was systematically evaluated through in vitro, device‐associated, and in vivo models. Integrated transcriptomic analysis revealed molecular responses underlying biofilm disruption, providing mechanistic insights and experimental evidence supporting phage cocktails as a promising strategy against

Phytochemical Composition, In Vitro Antioxidant, Antibacterial, and Antibiofilm Activities of Thymus vulgaris Essential Oil From Tiaret, Algeria

Chemistry &Biodiversity, Volume 23, Issue 8, August 2026.
Thymus vulgaris essential oil (TvEO), largely composed of thymol, showed strong bactericidal activity with Staphylococcus aureus (S. aureus) being most sensitive. TvEO markedly inhibited MRSA biofilm formation and significantly reduced established biofilms. Molecular docking suggests several TvEO components interact with proteins involved in S.

Quorum sensing controls Vibrio cholerae multicellular aggregate formation

eLife, 2018
Bacteria communicate and collectively regulate gene expression using a process called quorum sensing (QS). QS relies on group-wide responses to signal molecules called autoinducers.
