Raw amplicon sequencing data for: Interactive effects of nitrogen deposition and microplastics on rhizosphere soil microbial communities in Populus kangdingensis
AI summary Read the abstract
Scientists tested how microplastics (from plastic pollution) and nitrogen pollution together affect the tiny microbes living around tree roots, using a poplar tree species as their test case. This is a raw data release rather than a full study with conclusions, but the underlying research matters because soil microbes play a big role in plant health and environmental cleanup, and understanding how pollution disrupts these microbial communities could help us predict broader ecosystem impacts as microplastic and nitrogen pollution continue to rise.
Raw 16S rRNA (V4–V5) and ITS1 amplicon sequencing data from a factorial pot experiment testing the interactive effects of polyethylene and polylactic acid microplastics and nitrogen deposition on the rhizosphere microbiome of Populus kangdingensis. Twenty-seven samples (3 microplastic treatments × 3 nitrogen levels × 3 replicates). Sequenced on Illumina.

Scientists tested how microplastics (from plastic pollution) and nitrogen pollution together affect the soil bacteria and fungi living around poplar tree roots. This is a raw dataset release, not a full results paper, so it doesn't yet tell us the actual findings, but it's building the groundwork for understanding how these two common environmental pollutants might combine to disrupt soil ecosystems that plants, and ultimately our food and environment, depend on.
Investigation of Soil-Dwelling Bacterial Community Changes Induced by Microplastic Ex posure Using Amplicon Sequencing
AI summary Read the abstract
Researchers analyzed soil bacterial community composition after microplastic contamination, finding that different polymer types caused distinct shifts in microbial diversity and functional groups, with implications for soil nutrient cycling and agricultural productivity.
Mechanisms of polyethylene microplastics on microbial community assembly and carbon-nitrogen transformation potentials in soils with different textures
AI summary Read the abstract
Researchers used DNA sequencing to examine how polyethylene microplastics affect soil microbial communities and carbon-nitrogen cycling across soils with different textures. They found that microplastics significantly shifted microbial community composition and altered the abundance of genes involved in carbon and nitrogen transformation, with effects varying by soil type. The study suggests that microplastic contamination may disrupt fundamental nutrient cycling processes differently depending on soil characteristics.
Deciphering the response of nodule bacteriome homeostasis in the bulk soil-rhizosphere-root-nodule ecosystem to soil microplastic pollution
AI summary Read the abstract
Researchers examined how polyethylene microplastic contamination in soil affects the bacterial communities associated with legume plant root nodules. They found that microplastic treatments accelerated nodule formation but disrupted the balance of beneficial nitrogen-fixing bacteria in the nodules. The study suggests that soil microplastic pollution may interfere with the symbiotic relationship between legume crops and their nitrogen-fixing bacterial partners.
Bacteria and micro-eukaryotic in phenolic foam associated microplastics
AI summary Read the abstract
Researchers examined the bacterial and micro-eukaryotic communities associated with phenolic foam microplastics added at different concentrations to agricultural soils, using 16S and 18S rRNA gene sequencing. The study assessed how this foam-derived plastic pollution alters soil microbial community composition.
