Generalists and keystone species drive rhizosphere microbial diversity and stability in feral Brassica napus.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Brassica napus (rapeseed) is a globally important crop, primarily valued for its oil production. However, feral B. napus in non-agricultural areas remains under-researched. This study aims to examine the roles of microbial generalists and network keystone species in shaping microbial diversity and network stability of feral B. napus. We analyzed prokaryotic, fungal, and eukaryotic communities in the rhizosphere and bulk soil from five grassland sites. The rhizosphere microbial communities differed significantly from those in adjacent bulk soil, showing lower diversity and richness. Pseudomonas brassicacearum (bacterium), Olpidium brassicae (fungus), and Glissomonadida (eukaryote) were predominantly found in the rhizosphere. Inter- and intra-kingdom association occurred almost exclusively within the rhizosphere, with low interconnectivity compared to the bulk soil, and network keystone species served to bridge these connections. Furthermore, structural equation modeling highlighted the role of generalists and network keystone species in maintaining microbial diversity and stability. Feral B. napus selectively influenced rhizospheric generalists, which, along with keystone species, played key roles in determining microbial diversity and network stability, controlling community structure and interspecies interactions.
