ClearMicroplastics increase soil microbial network complexity and trigger diversity-driven community assembly
Researchers found that microplastics in soil increased bacterial network complexity and shifted microbial community assembly in a diversity-dependent manner, with high-density polyethylene causing more harm to plant growth than polystyrene or polylactic acid particles.
Polyethylene Microplastic Particles Alter the Nature, Bacterial Community and Metabolite Profile of Reed Rhizosphere Soils
Researchers found that polyethylene microplastic particles alter the bacterial community composition, soil environmental factors, and metabolite profiles of reed rhizosphere soils, with effects increasing at higher microplastic concentrations and showing distinct interactions with reed biomass.
Microplastics reduce soil microbial network complexity and ecological deterministic selection
Researchers found that microplastics reduce soil microbial network complexity and shift community assembly from deterministic to more stochastic processes, suggesting that microplastic pollution may fundamentally alter microbial ecological interactions in terrestrial systems.

Effects of polyethylene microplastics on the microbial community structure of maize rhizosphere soil
Researchers investigated how polyethylene microplastics from agricultural films affect the microbial communities in crop root zones (rhizosphere), finding shifts in bacterial diversity and function. Disrupting soil microbiomes through microplastic contamination could have downstream effects on soil fertility and crop health.
Polyethylene microplastics alter soil microbial community assembly and ecosystem multifunctionality
Researchers studied how polyethylene microplastics at different concentrations affect soil microbial communities and overall ecosystem function in a maize growing system. They found that higher concentrations of microplastics shifted microbial community composition, reduced beneficial bacteria involved in nutrient cycling, and impaired multiple soil ecosystem functions simultaneously. The study suggests that microplastic contamination in agricultural soils can undermine the biological processes that support healthy crop growth.
Deciphering the response of nodule bacteriome homeostasis in the bulk soil-rhizosphere-root-nodule ecosystem to soil microplastic pollution
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.
Impacts of non-spherical polyethylene nanoplastics on microbial communities and antibiotic resistance genes in the rhizosphere of pea (Pisum sativum L.): An integrated metagenomic and metabolomic analysis
Researchers exposed pea plants to non-spherical polyethylene nanoplastics at 0, 20, and 200 mg/kg, finding that high doses significantly inhibited plant growth, restructured rhizosphere microbial communities, and elevated antibiotic resistance gene abundance via integrated metagenomics and metabolomics.
Rhizospheric bacterial communities against microplastics (MPs): Novel ecological strategies based on the niche differentiation
Researchers studied how bacterial communities living around plant roots adapt when exposed to microplastics in soil. They found that rhizosphere bacteria developed distinct survival strategies depending on their ecological niche, with some species thriving while others declined in the presence of plastics. The study reveals that microplastics can reshape the microbial communities that plants depend on for nutrient uptake and disease resistance.
Mechanisms of polyethylene microplastics on microbial community assembly and carbon-nitrogen transformation potentials in soils with different textures
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.

These shifts could have downstream consequences for plant health and soil nutrient cycling.
Polyethylene microplastic pollution drives quorum sensing-mediated enrichment of rhizosphere pathogens, resistance genes, and virulence factors genes
Researchers studied how polyethylene microplastics in soil affect the root-associated microbiome of a medicinal plant and found dose-dependent increases in antibiotic resistance genes, virulence factors, and human pathogens. The microplastics appeared to promote quorum sensing, a bacterial communication system that helps coordinate these harmful traits. The findings suggest that microplastic soil pollution could amplify microbial risks in agricultural settings.
