Soil-dwelling Naegleria enhances plant performance by stimulating beneficial bacterial functions in the rhizosphere.
Article in Nature communications, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 papers.
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
Soil protists play vital roles in influencing plant performance, yet their interactions with plant-beneficial bacteria are still poorly understood. Here, we examine how two soil protists (Naegleria sp. and Cercomonas sp.) affect the pathogen Ralstonia solanacearum, both on individual beneficial bacteria and within a synthetic microbial community (SynCom). Combining in vitro and pot experiments, we find that the SynCom together with Naegleria provided significantly greater suppression of the pathogen (enhanced suppressiveness by 74.29% compared to SynCom alone). Additionally, Naegleria increases SynCom biofilm biomass by 2.44 times. Population dynamics tracking revealed that Naegleria enriched Bacillus populations, leading to a positive correlation between Bacillus and Pseudomonas. Metatranscriptomics analysis shows upregulation of genes related to biofilm formation (such as epsA-O and tapA-sipW-tasA operon) and secondary metabolite biosynthesis (e.g., macrolactin H, bacillaene, and difficidin) in the presence of Naegleria. Our study demonstrates that Naegleria enhances plant health by predating on pathogens, promoting beneficial bacteria, and stimulating protective microbial functions in the rhizosphere.
