Structural and functional properties of bacterial communities associated with rootless duckweed (Wolffia globosa) and their effect on the Wolffia growth.
Article in Environmental microbiome, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundRootless duckweed, Wolffia globosa, is emerging as a high-protein and starch biomass resource for various applications. However, the microbiomes and functional properties associated with Wolffia across a wide range of microbial sources remain largely unexamined. This study investigates the structure and functioning of the Wolffia microbiome and its impact on plant growth.
resultsA co-cultivation experiment with axenic W. globosa and bacterial communities derived from various sources revealed varied effects, that municipal wastewater-derived bacterial communities had a more pronounced positive effect on growth of W. globosa compared to those from pond water. 16S rRNA amplicon sequencing found that Beijerinckiaceae, Caulobacteraceae, Comamonadaceae, Methylophilaceae, Rhizobiaceae, and Sphingomonadaceae were consistently conserved and identified as core taxa in the Wolffia microbiome. Functional profiling indicated that genes related to bacterial colonization and adaptation to the rootless morphology contribute to selective microbiome recruitment, with enriched functions in motility, chemotaxis, flagella assembly, quorum sensing, and ABC transporters. In addition, it was found that Bdellovibrionaceae, Beijerinckiaceae, and Sphingomonadaceae may act as "hub microorganisms" and "keystone taxa," shaping community structure and directly or indirectly influencing Wolffia growth.
conclusionCollectively, the results of this study unveiled the robust core taxa and functional profiles of the Wolffia microbiome across diverse microbial sources, with certain taxa differing from those in rooted duckweed. This study comprehensively characterizes the Wolffia microbiome and enhances understanding of it, providing insights for developing efficient biomass production systems.
