Two-step localization driven by peptidoglycan hydrolase in interbacterial predation.

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
Mechanisms of bacterial predation are crucial for revealing microbial adaptation strategies and interaction behaviors in the environment, yet they remain poorly understood. Previously, predators were reported to localize prey via specific cues. However, the process and mechanisms by which these cues, including signaling molecules, mediate predator localization remain unclear. Herein, we investigate the dynamic interaction between the predatory bacteria Lysobacter enzymogenes and its prey bacteria. By integrating genetic manipulation, transcriptomic analysis, biochemical assays, and live-cell tracking microscopy at the single-cell level, we present a novel predation strategy mediated by peptidoglycan hydrolase LssL, named peptidoglycan hydrolase-driven Prey Localization and Utilization System (phPLUS). In phPLUS, predators secrete LssL to initiate the Step I of the localization process. LssL then hydrolyzes prey and releases small molecules of glycine, which serve as signaling cues to guide the predator's directional movement and promote the Step II of localization. In turn, prey signals upregulate the expression of LssL, which synergize with type VI secretion system to ultimately mediate prey killing through a novel regulatory pathway. This study reveals a new two-step localization strategy in bacterial predation, highlighting a previously unrecognized predation process and signal regulation mechanism, and expanding our understanding of predator-prey interactions and microbial ecological dynamics.
