ClearSelenium alleviates the adverse effects of microplastics on kale by regulating photosynthesis, redox homeostasis, secondary metabolism and hormones
Researchers found that treating soil with selenium could protect kale plants from the harmful effects of microplastic contamination. Microplastics triggered damaging oxidative stress in the plants, but selenium helped restore the balance by boosting antioxidant defenses, improving photosynthesis, and regulating plant hormones. This suggests selenium supplementation could help maintain food crop health in microplastic-contaminated agricultural soils.

Researchers found that inoculating soybean plants with a combination of mycorrhizal fungi and beneficial bacteria helped protect them from microplastic-induced stress, improving biomass, seed quality, antioxidant defenses, and hormone balance. The study suggests that soil microbe communities could be harnessed as a sustainable strategy to help crops cope with growing microplastic contamination in agricultural soils.
Selenium-driven trophic restructuring of soil nematode communities and biochemical regulation alleviate the toxicity caused by microplastic pollution in highland barley
Researchers investigated whether selenium supplementation could counteract the harmful effects of polyethylene microplastics on highland barley and soil nematode communities. They found that microplastics significantly reduced plant growth metrics and disrupted nematode populations, but selenium application helped restore chlorophyll content, root development, and beneficial soil organism diversity. The study suggests that selenium may serve as a practical tool for mitigating microplastic-induced damage in agricultural soils.
From energy collapse to chemical defense: Microplastics reshape the metabolic landscape of Tetrastigma hemsleyanum (Vitaceae)
Researchers investigated how polystyrene microplastics affect the medicinal plant Tetrastigma hemsleyanum, confirming that the particles accumulate in roots and travel to leaves through the vascular system. Microplastic exposure caused significant oxidative damage, a 42.5% reduction in chlorophyll content, and disrupted photosynthetic energy metabolism. The plant responded by redirecting metabolic resources from carbon fixation toward producing antioxidant flavonoid compounds as a defense mechanism.
Dual-Stress Mitigation of Sclerotinia under Microplastic Toxicity by Nano-Selenium: Redox Balance, Pathogen Suppression, and Transcriptome Reprogramming
Researchers investigated whether selenium nanoparticles could protect rapeseed plants from combined stress caused by microplastics and the fungal pathogen Sclerotinia. The study found that selenium nanoparticles improved photosynthesis, reduced oxidative damage, and showed strong antifungal activity, suggesting they may help mitigate microplastic-induced phytotoxicity and fungal disease in agricultural settings.
The response of Panax notoginseng to combined microplastics and cadmium stress and its mechanism of rhizosphere microorganisms and root metabolites
A pot experiment investigated how polyethylene microplastics interact with cadmium — a toxic heavy metal common in agricultural soils — to affect the growth and chemistry of Panax notoginseng, a valuable medicinal plant. At low microplastic concentrations combined with low cadmium, plant biomass actually increased; at higher concentrations, growth was inhibited and cadmium accumulated in the roots. Microplastics also altered the plant's production of medicinally important compounds like flavonoids, and shifted which microbes thrived in the root zone. These results show that combined microplastic-heavy metal contamination can affect both the safety and therapeutic quality of medicinal crops.
Revealing the Selenium-Mediated Regulatory Mechanisms of P. stratiotes in Response to Nanoplastics Stress from Multiple Perspectives of Transcriptomics, Metabolomics, and Plant Physiology
Scientists found that tiny plastic particles (nanoplastics) seriously damage water plants by disrupting their ability to make food from sunlight and causing harmful stress inside their cells. However, when researchers added selenium (a natural mineral) to the water, it helped protect the plants from plastic damage by boosting their natural defense systems. This research could help us clean up plastic pollution in lakes and rivers, which is important since these water sources can affect human health through drinking water and food chains.
Astragalus Polysaccharides Ameliorate the Toxic Effects of Polystyrene Nanoplastics on Boar Sperm
Scientists found that tiny plastic particles called nanoplastics can damage sperm cells by causing harmful chemical reactions, but a natural compound from the Astragalus plant can help protect against this damage. This study used pig sperm in lab dishes, so we don't know yet if the same protection would work in humans. The findings matter because microplastics are everywhere in our environment and food, and this research suggests natural antioxidants might help reduce their potential harm to reproductive health.

Effects of polystyrene microplastics on the growth and metabolism of highland barley seedlings based on LC-MS
Researchers exposed highland barley seedlings to different concentrations of polystyrene microplastics and found that low to medium levels actually increased plant growth, while high levels significantly reduced it. The microplastics triggered oxidative stress and disrupted key metabolic pathways involved in flavonoid production, energy metabolism, and fatty acid production. These changes to crop metabolism could affect the nutritional quality and safety of food crops grown in microplastic-contaminated soil.

SeNPs improved seed germination, reduced oxidative damage, and altered gene expression to restore redox balance — largely reversing the dual stress effects.
Silicon regulates microplastic-induced phytotoxicity and its detoxification mechanism: A plant-microbe perspective
Researchers investigated whether silicon supplements could protect kale from the harmful effects of polyethylene microplastics in soil. They found that silicon increased plant biomass by 16-25% and reversed microplastic-induced suppression of soil enzymes, while also promoting beneficial soil bacteria. The study suggests that silicon could be a practical strategy for improving crop resilience in microplastic-contaminated agricultural soils.

The findings highlight the complex and sometimes contradictory ways microplastics can influence agricultural ecosystems.
