ClearFrom the shoot to the rhizosphere: The short-term cascade impact of aerial microplastic
Researchers tested how foliar polyethylene microsphere exposure in tomato plants cascades from leaf physiological changes to altered root metabolite composition and root-associated microbiome structure, finding that aerial MP exposure reshapes plant-soil interactions through systemic signaling.
Potential impacts of two types of microplastics on Solanum lycopersicum L. and arbuscular mycorrhizal fungi
Researchers investigated the potential impacts of two types of microplastics on tomato (Solanum lycopersicum) plants and arbuscular mycorrhizal fungi, examining how plastic pollution may disrupt plant-fungal symbiotic relationships in agricultural soils.
Effects of microplastics polluted soil on the growth of Solanum lycopersicum L.
This study tested how microplastic-contaminated soil affects tomato plant growth, finding that higher concentrations of plastic particles in soil reduced plant height, root development, and overall crop health. The results suggest that microplastic pollution in farmland could reduce food crop yields and potentially affect the quality of the produce we eat.
Impacts of Microplastics and Nanoplastics on Tomato Crops: A Critical Review
This review covers the impacts of microplastics and nanoplastics on tomato crops, documenting disruption at germination, root development, flowering, and fruit production stages. It also examines how these particles alter soil microbial communities and identifies priority research areas for understanding MP effects on major food crops.
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.
The effects of biosolid microplastics on rhizosphere respiration of root exudates in Glycine max
This study examined how microplastics from agricultural biosolids affect the activity of soil microbes around soybean roots. Researchers found that both polyethylene and polypropylene microplastics increased baseline microbial respiration rates, and high concentrations of polypropylene fragments significantly altered how soil microbes consumed amino acid-based root compounds. The findings suggest that microplastics in agricultural soil can change the way root-zone microbial communities process plant nutrients.
Type-dependent effects of microplastics on tomato (Lycopersicon esculentum L.): Focus on root exudates and metabolic reprogramming
Researchers grew tomato plants in the presence of three different types of microplastics and found that each type produced distinct effects on plant physiology, root secretions, and metabolic processes. Polystyrene had the strongest negative impact, significantly altering root exudate composition and triggering metabolic reprogramming in the plants. The study demonstrates that the type of plastic matters when assessing how microplastic pollution affects crop growth and soil chemistry.
Addition of polyester microplastic fibers to soil alters the diversity and abundance of arbuscular mycorrhizal fungi and affects plant growth and nutrition
Researchers added polyester microplastic fibers to soil microcosms and monitored changes in microbial diversity and abundance over time, finding that fibers altered soil bacterial and fungal community structure at realistic environmental concentrations.
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.
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 microplastics also shifted the soil microbiome toward potentially harmful fungi and bacteria. These findings show that microplastics in agricultural soil can damage crop health and change the microbial community that plants depend on.
Can RhizosphereEffects Mitigate the Threat from Nanoplasticsand Plastic Additives to Tomato (Solanum lycopersicum L.)?
Researchers used a root-box system to examine how nanoplastics and the plasticizer DEHP interact in the rhizosphere of tomato plants, finding that DEHP dominated the plastic pollution risk to plants and that nanoplastic co-exposure did not mitigate DEHP toxicity to soil microorganisms but increased it for food safety.
Can microplastics threaten plant productivity and fruit quality? Insights from Micro-Tom and Micro-PET/PVC
Researchers grew tomato plants in soil containing environmentally realistic levels of PET and PVC microplastics and found mixed effects on plant productivity and fruit quality. While some growth parameters were affected, the microplastics also altered the mineral content of the tomatoes. This study suggests that microplastics in agricultural soil could change the nutritional profile of the food we eat.
Impact of Polystyrene Microplastics on Soil Properties, Microbial Diversity and Solanum lycopersicum L. Growth in Meadow Soils
Researchers tested how polystyrene microplastics of different sizes and concentrations affect tomato plant growth and soil microbes. Surprisingly, some microplastic treatments boosted plant growth and soil nutrients, while others reduced microbial diversity and disrupted soil community networks. The mixed results show that microplastic effects on agriculture are complex and depend on particle size and concentration, making it difficult to predict how contaminated soil will affect food crops.

Researchers found that microplastic particles altered wheat rhizosphere soil microbial community composition and function, with different polymer types inducing distinct shifts in bacterial diversity and nutrient cycling processes.
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.

Can Rhizosphere Effects Mitigate the Threat from Nanoplastics and Plastic Additives to Tomato (Solanum lycopersicum L.)?
Researchers investigated whether the rhizosphere, the zone of soil around plant roots, can mitigate the combined threats of nanoplastics and the plastic additive DEHP to tomato plants. The study found that while the rhizosphere provided some protective effects against soil contamination, the coexistence of nanoplastics and DEHP actually increased risks to food safety compared to DEHP alone, indicating that plastic pollution compounds the threat from plastic additives.
