Extracellular vesicles as structured vectors of quorum sensing signals influence aquatic microbial communities [PDF]
npj Biofilms and MicrobiomesQuorum sensing (QS) orchestrates collective microbial behaviors and functional acclimatization through chemical communication. However, QS in natural waters is challenged by dilution, alkaline hydrolysis, and enzymatic degradation of freely dissolved ...

Functional metagenomic analysis of quorum sensing signaling in a nitrifying community. [PDF]
NPJ Biofilms Microbiomes, 2022 Quorum sensing (QS) can function to shape the microbial community interactions, composition, and function. In wastewater treatment systems, acylated homoserine lactone (AHL)-based QS has been correlated with the conversion of floccular biomass into ...

LuxR402 of Novosphingobium sp. HR1a regulates the correct configuration of cell envelopes [PDF]
Front Microbiol, 2023 Although there is some evidence to suggest that LuxR-solo proteins participate in inter-species or even inter-kingdom communication, most of the LuxR-solo protein functions are unknown.

Studies on synthetic LuxR solo hybrids [PDF]
Frontiers in Cellular and Infection Microbiology, 2015 A sub-group of LuxR family of proteins that plays important roles in quorum sensing, a process of cell-cell communication, is widespread in proteobacteria. These proteins have a typical modular structure consisting of N-ter autoinducer binding and C-ter helix-turn-helix (HTH) DNA binding domains.

LuxR-family ‘solos’: bachelor sensors/regulators of signalling molecules [PDF]
Microbiology, 2009 N-Acylhomoserine lactone (AHL) quorum-sensing (QS) signalling is the best-understood chemical language in proteobacteria. In the last 15 years a large amount of research in several bacterial species has revealed in detail the genetic, molecular and biochemical mechanisms underlying AHL signalling. These studies have revealed the role

Phytohormone-mediated interkingdom signaling shapes the outcome of rice-Xanthomonas oryzae pv. oryzae interactions [PDF]
, 2015 Background: Small-molecule hormones are well known to play key roles in the plant immune signaling network that is activated upon pathogen perception. In contrast, little is known about whether phytohormones also directly influence microbial virulence ...
