ClearAgri-plastics in soils drive changes in the rhizosphere bacterial community and plant transcriptome in Arabidopsis
Researchers grew Arabidopsis thaliana in soils mixed with plastic film residues (≥5 mm at 5% w/w) and examined rhizosphere bacterial communities and plant gene expression. Plastic residues significantly altered rhizobacterial composition without affecting plant growth or flowering, suggesting soil microbiome disruption may precede visible plant effects.

Microplastics 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.
Impact of Nanoplastic Contamination on Rhizosphere Microbiome and Plant Phenotype
This study examined how nanoplastic contamination affects the rhizosphere microbiome (soil bacteria around plant roots) and plant growth. Nanoplastic exposure altered soil microbial communities and reduced plant growth, suggesting these tiny plastic particles could disrupt the soil ecosystems that support food production.
Potential impacts of polyethylene microplastics and heavy metals on Bidens pilosa L. growth: Shifts in root-associated endophyte microbial communities
Researchers found that polyethylene microplastics in soil contaminated with heavy metals significantly stunted plant growth, reducing root length by nearly 49% and increasing harmful reactive oxygen species in plant tissues. The microplastics also shifted the soil's microbial communities toward stress-resistant species, demonstrating how plastic pollution can disrupt the soil ecosystem that supports our food supply.

Researchers found that low-density polyethylene (LDPE) microplastic contamination in field soil negatively affected fenugreek plant growth, root nodulation, and rhizosphere microbial community structure, raising concerns about agricultural soil health.
Reprogramming of microbial community in barley root endosphere and rhizosphere soil by polystyrene plastics with different particle sizes
Barley plants grown in polystyrene microplastic- and nanoplastic-contaminated soil showed altered microbial communities in both the root endosphere and rhizosphere, suggesting plastic pollution can reshape plant-associated microbiomes. These shifts could have downstream consequences for plant health and soil nutrient cycling.
Living in the plastic age - Different short-term microbial response to microplastics addition to arable soils with contrasting soil organic matter content and farm management legacy
Adding polyethylene or polypropylene microplastics to two agricultural soils did not severely disrupt overall microbial activity or nitrogen cycling, but polypropylene reduced microbial biomass, especially in the organically managed soil. The results suggest that soil management history influences how resilient soil microbiomes are to microplastic contamination.
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.

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.
[Effect of Low-density Polyethylene Microplastics on Soybean-soil-microbial System].
A pot experiment explored how different concentrations of low-density polyethylene microplastics affect soybean plants, the soil they grow in, and the microbial communities in that soil. Higher microplastic concentrations inhibited soybean growth, reduced soil enzyme activity, and altered microbial diversity in ways that could impair soil fertility. As microplastic contamination of agricultural soils continues to grow, these findings suggest real risks to food crop productivity and soil ecosystem health.
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.
From the rhizosphere to plant fitness: Implications of microplastics soil pollution
Researchers exposed strawberry plants to low-density polyethylene microplastics in soil and found significant harm, including reduced chlorophyll levels, altered nutrient uptake, and increased stress responses.

The study highlights the compounding environmental risks when antibiotics from animal manure and microplastics from plastic films co-exist in farmland soils.
