ClearPotential Effects of Microplastic on Arbuscular Mycorrhizal Fungi
This review examines how microplastics in soil affect arbuscular mycorrhizal fungi, finding evidence that microplastics can alter fungal colonization of plant roots, spore production, and the broader soil microbiome, with cascading effects on plant nutrient uptake.
Arbuscular mycorrhizal fungi enhance maize cadmium resistance and reduce translocation: Dependence on microplastics concentration
Researchers investigated how beneficial soil fungi called arbuscular mycorrhizal fungi can help maize plants resist cadmium toxicity in soils contaminated with both microplastics and heavy metals. They found that high concentrations of polyethylene microplastics worsened cadmium toxicity, but inoculation with mycorrhizal fungi significantly improved plant growth, nutrient uptake, and photosynthesis. The study suggests that these fungi could serve as a biological tool for managing crop health in soils with combined microplastic and heavy metal contamination.
Effects of microplastics on the plant-arbuscular mycorrhizal fungal symbiotic system: type, size, and concentration
This review examines how different types, sizes, and concentrations of microplastics affect the symbiotic relationship between plants and arbuscular mycorrhizal fungi in soil. The study found that low microplastic concentrations may stimulate fungal colonization, while higher levels generally inhibit it, and that biodegradable microplastics and nanoplastics tend to have stronger effects on the plant-fungal system than conventional microplastics.
Nitrogen fertilization and arbuscular mycorrhizal fungi do not mitigate the adverse effects of soil contamination with polypropylene microfibers on maize growth
Researchers tested whether adding nitrogen fertilizer or beneficial soil fungi could offset the negative effects of polypropylene microfibers on maize plants. They found that neither nitrogen supplementation nor mycorrhizal fungi helped the plants overcome the growth reductions caused by microplastic contamination. The study suggests that microplastics harm crops through mechanisms beyond simple nutrient limitation, and that conventional farming practices may not be sufficient to counteract microplastic damage to soil health.
The mycorrhizal symbiosis: research frontiers in genomics, ecology, and agricultural application
This review covers the latest advances in understanding mycorrhizal fungi, which form partnerships with plant roots to help them absorb nutrients and resist stress. While not directly about microplastics, mycorrhizal networks play a critical role in soil health, and research shows that microplastic contamination in soil can disrupt these beneficial fungal partnerships. Healthy mycorrhizal networks may also help buffer plants against some negative effects of soil pollutants, including microplastics.
Interactions of microplastics and cadmium on plant growth and arbuscular mycorrhizal fungal communities in an agricultural soil
Researchers studied how polyethylene and polylactic acid microplastics interact with cadmium contamination to affect maize growth and beneficial soil fungi in agricultural soil. While polyethylene showed minimal direct plant toxicity, high doses of polylactic acid significantly reduced maize biomass, and both plastic types altered the communities of root-associated fungi. The study suggests that co-contamination of microplastics and heavy metals in farmland can jointly disrupt plant health and soil ecosystems.
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.
Microplastics modify plant-arbuscular mycorrhizal fungi systems in a Pb-Zn-contaminated soil
Researchers examined how six types of microplastics affect sweet sorghum growth and soil fungal communities in soil contaminated with lead and zinc. They found that microplastics generally did not inhibit plant growth and in some cases promoted it, but they increased the uptake of heavy metals into plant shoots. The study suggests that microplastics may worsen the risks of heavy metal contamination in agricultural soils by enhancing metal accumulation in crops.
Effects of microplastic types and shapes on the community structure of arbuscular mycorrhizal fungi in different soil types
Researchers examined how different types and shapes of microplastics affect arbuscular mycorrhizal fungi communities across various soil types. The study found that microplastics alter soil structure and chemistry in ways that disrupt these beneficial fungi, which play crucial roles in nutrient exchange, soil stability, and water movement.
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.
Migration and accumulation of microplastics in soil-plant systems mediated by symbiotic microorganisms and their ecological effects
This study found that beneficial soil fungi (mycorrhizal fungi) actually accelerate the uptake of smaller microplastics by plant roots while slowing the uptake of larger ones. The microplastics disrupted the symbiotic relationship between the fungi and plants, reducing plant nutrient absorption and growth, which matters because crops grown in microplastic-contaminated soil may be less nutritious.
Arbuscular mycorrhizal fungi change toxic effects of different types of microplastics on Lactuca sativa L. by influencing plant metabolic processes
Researchers examined how beneficial soil fungi called arbuscular mycorrhizal fungi influence the toxic effects of different microplastics on lettuce. The study found that these fungi reduced the uptake and toxicity of PET microplastics but actually promoted the absorption of polypropylene and polystyrene, indicating that the interaction between soil microorganisms and microplastics depends strongly on polymer type.
Effects of microplastics on crop nutrition in fertile soils and interaction with arbuscular mycorrhizal fungi
Researchers found that microplastic fibers at 0.4% concentration in soil disrupted potassium, magnesium, and sulfur uptake in onions, but that inoculation with arbuscular mycorrhizal fungi buffered these negative effects by enhancing nutrient availability and plant uptake.
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.
Effects of different microplastics on the activation of soil potassium by ectomycorrhizal fungi
This study found that both polypropylene (PP) and polylactic acid (PLA) microplastics hindered the growth of an ectomycorrhizal fungus and reduced how much potassium it could release from soil for plants, with PLA being the more harmful of the two. The findings matter because mycorrhizal fungi are critical for forest nutrient cycling, and microplastic contamination of soils could quietly degrade this ecosystem service.
Evaluating the Impact of Traditional and Biodegradable Mulch Film Residues on Heavy Metal Dynamics and Maize Productivity: Insights from Arbuscular Mycorrhizal Fungi Community Analysis
Researchers compared the long-term effects of traditional polyethylene and biodegradable mulch film residues on soil properties, heavy metal uptake in maize, and beneficial soil fungi communities. Traditional mulch residues increased the accumulation of arsenic and cadmium in maize roots while altering soil chemistry, whereas biodegradable mulch residues also affected fungal communities but in different ways. The study suggests that neither type of mulch film is without environmental consequence, and that their residues can influence both crop safety and soil microbial health.
Arbuscular mycorrhizal fungi and glomalin mediate the effects of microplastics on soil carbon storage
Arbuscular mycorrhizal fungi and a soil protein called glomalin were found to mediate the effects of microplastics on plant growth and soil structure. This suggests that the ecological impact of microplastics in agricultural soils is shaped by the presence and health of fungal communities that support plant nutrition.
Effects of Microplastics and Arbuscular Mycorrhizal Fungi on Soybean Growth and Soil Greenhouse Gas Emissions in a sandy-loam
Researchers investigated how microplastics and arbuscular mycorrhizal fungi interact to affect soybean growth and greenhouse gas emissions in sandy-loam soil, examining whether fungal colonization can mitigate microplastic-induced stress on plant development.
Arbuscular Mycorrhizal Fungi Can Inhibit the Allocation of Microplastics from Crop Roots to Aboveground Edible Parts
Scientists discovered that beneficial soil fungi called arbuscular mycorrhizal fungi can reduce the amount of microplastics that travel from plant roots into the edible parts of lettuce. Plants grown with these fungi transported significantly fewer plastic particles to their leaves compared to plants without them. The findings suggest that natural fungal partnerships in soil could serve as a biological barrier helping protect food crops from microplastic contamination.
Impact of Coexistence of Microplastics and Biochar on the Abundance and Structure of Soil Fungal Communities
Researchers investigated the effects of polypropylene, polyethylene, and PVC microplastics — alone and in combination with biochar — on soil fungal community structure, diversity, and functional prediction in agricultural soil. Microplastics increased overall fungal abundance but reduced diversity indices, with dominant taxa including Ascomycota, Basidiomycota, Mortierella, Aspergillus, and Fusarium, and coexistence with biochar amplifying these effects beyond microplastics alone.
