Biodegradable plastic exposure enhances microbial functional diversity while reducing taxonomic diversity across multi-kingdom soil microbiota in cherry tomato fields.
Article in Communications biology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Plastic films are extensively utilized in agroecosystems, and their residues are accumulating in global soil at a worrying rate. Biodegradable films are employed as a substitute for polyethylene (PE) films due to their rapid degradation rate. Although the taxonomic diversity of soil microbiome in response to biodegradable films has been studied, its alterations in functional diversity remain unexplored. Here, we conduct a two-year field experiment in cherry tomato to address how PE and poly (butylene adipate-co-terephthalate) (PBAT) influences soil microbiota across multi-kingdom (bacteria, fungi, and protists) regarding its taxonomic and functional diversity. The results show that PBAT exposure reduces the taxonomic diversity while increasing functional diversity across multi-kingdom domains compared to PE exposure. We further find that the decreased taxonomic diversity under PBAT exposure reduces the complexity of microbial inter-kingdom and internal-kingdom networks. Conversely, PBAT exposure enhances microbial functional diversity (Shannon index) and average genome size, accompanied by elevated abundances of plastic-degrading genes as well as carbon, nitrogen, phosphorus, and sulphur cycling functional genes. Overall, our study indicates that environmental filtration induced by PBAT exposure changes the microbial life adaptive strategies and leads to a decoupling between taxonomic diversity and functional diversity.
