Extracellular vesicles as structured vectors of quorum sensing signals influence aquatic microbial communities.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Quorum 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 autoinducers. Here, we demonstrate that extracellular vesicles (EVs) act as selective, durable, and protective vectors for QS signal molecules under environmental stresses. Specifically, EVs preferentially package hydrophobic acyl‑homoserine lactones, concentrate them locally, and shield them from alkaline hydrolysis, and exhibiting long-distance transport. In addition, EVs possess specific affinity to recipients, thus influencing microbial community. Field investigation via multi-omics showed that EV abundance covaried with salinity, nutrients, chlorophyll a, and biomass, which were validated by culture experiments. Our statistical framework demonstrated that organisms producing moderate EV levels contributed significantly to maintaining community stability and ecosystem functions. Distinctively within this group, QS-active species (including Burkholderiaceae, Pseudomonadaceae, Rhodobacteraceae, Roseobacteraceae, Flavobacteriaceae etc.) emerge as key drivers facilitating these crucial ecological roles. Furthermore, metaproteomics of field EVs reveal QS receptor and synthesis proteins, suggesting coordinated transport of signals and proteins, which indicate new routes for QS crosstalk, particularly for taxa bearing luxR/I solos. Our results show that moderately generated EVs are the potentially important QS signal carriers and ecological regulation hubs in natural waters.
