Regulation of LuxPQ Receptor Activity by the Quorum-Sensing Signal Autoinducer-2 [PDF]
Molecular Cell, 2005 The extracellular signaling molecule autoinducer-2 (AI-2) mediates quorum-sensing communication in diverse bacterial species. In marine vibrios, binding of AI-2 to the periplasmic receptor LuxP modulates the activity of the inner membrane sensor kinase LuxQ, transducing the AI-2 information into the cytoplasm.

LuxS-dependent AI-2 production is not involved in global regulation of natural product biosynthesis in Photorhabdus and Xenorhabdus [PDF]
PeerJ, 2017 The Gram-negative bacteria Photorhabdus and Xenorhabdus are known to produce a variety of different natural products (NP). These compounds play different roles since the bacteria live in symbiosis with nematodes and are pathogenic to insect larvae in the

From Circuits to Symphonies: A Systems‐Engineering Blueprint for Multimicrobial Synthetic Biology
Advanced Science, Volume 13, Issue 49, 3 September 2026.Engineering synthetic microbial consortia requires moving beyond intracellular genetic circuits toward coordinated multicellular design. A modular systems‐engineering framework is presented that integrates communication, temporal coordination, ecological structuring, and predictive modeling to guide application‐dependent consortium design ...

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

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.

Frontiers in Microbiology, 2017 Bacteria use autoinducer molecules to communicate both at intra-species and inter-species levels by quorum sensing. One such cell density-dependent signaling system is the luxS-mediated universal quorum sensing using autoinducer-2 (AI-2).

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‐

Pengaruh Bakteri Tanah A Terhadap Autoinducer pseudomonas sp Penghasil Pigmen Jingga [PDF]
, 2007 Dalam suatu populasi bakteri, bakteri dapat berkomunikasi antara bakteri yang satu dengan bakteri yang lainnya dengan manggunakan suatu sinyal berupa molekul kecil yang disebut autoinducer yang disekresikan ke lingkungan ekstraselulernya. Komunikasi

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
