ClearRevealing 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.
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.
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.
Dual-Stress Mitigationof Sclerotinia under MicroplasticToxicity by Nano-Selenium: Redox Balance, Pathogen Suppression, andTranscriptome Reprogramming
Researchers tested whether selenium nanoparticles (SeNPs) could protect rapeseed plants from the combined stress of microplastic contamination and Sclerotinia sclerotiorum fungal infection. SeNPs improved seed germination, reduced oxidative damage, and altered gene expression to restore redox balance — largely reversing the dual stress effects.
Selenium 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.
Nano-selenium ameliorates microplastics-induced injury: Histology, antioxidant capacity, immunity and intestinal microbiota of grass carp (Ctenopharyngodon idella)
Researchers tested whether nano-selenium supplements could protect grass carp from damage caused by polystyrene microplastics. They found that nano-selenium reduced the tissue damage, oxidative stress, and immune suppression caused by microplastic exposure, and helped restore healthy gut bacteria. The study suggests that dietary nano-selenium may be a practical strategy for protecting farmed fish from the harmful effects of microplastic pollution in aquatic environments.
The effects of Micro/Nano-plastics exposure on plants and their toxic mechanisms: A review from multi-omics perspectives.
A multi-omics review of micro/nanoplastic effects on plants found that plastic exposure disrupts gene expression, protein function, and metabolic pathways across multiple plant systems, with potential consequences for crop yield and agricultural food safety.
Nano- and microplastics commonly cause adverse impacts on plants at environmentally relevant levels: A systematic review
Systematic review of 78 studies found that nano- and microplastics commonly cause adverse effects on plants even at environmentally relevant concentrations, with germination and root growth more strongly affected than shoot growth during early development. Chlorophyll levels were consistently reduced while stress indicators (ROS) and antioxidant enzymes were consistently upregulated across species.
The threat of micro/nanoplastic to aquatic plants: current knowledge, gaps, and future perspectives
This review summarizes what is known about how micro- and nanoplastics affect aquatic plants, including how plants absorb these particles through roots and leaves and transport them internally. Exposure can alter plant growth, photosynthesis, and interactions with other organisms, though effects vary widely depending on plastic type and concentration. The authors highlight major research gaps and call for more studies on real-world conditions rather than controlled lab settings.
Unveiling the mechanism of micro-and-nano plastic phytotoxicity on terrestrial plants: A comprehensive review of omics approaches.
This comprehensive review examined how micro-and-nano plastics (MNPs) in terrestrial soils damage plant health by inhibiting water and nutrient uptake, reducing seed germination, impairing photosynthesis, and inducing oxidative stress. The review identified key knowledge gaps in understanding MNP phytotoxicity mechanisms and their implications for food security.
Unraveling the toxic mechanisms of microplastics in aquatic ecosystem: A case study on Vallisneria natans and Myriophyllum verticillatum
Researchers exposed two submerged aquatic plant species (Vallisneria natans and Myriophyllum verticillatum) to PVC, polystyrene, and polyethylene microplastics at three concentrations, finding that all three types significantly inhibited photosynthesis and growth and triggered oxidative stress, with effects varying by plastic type and plant species.
Integrated physiological, transcriptomic, and metabolic analysis reveals the effects of nanoplastics exposure on tea plants
Researchers used physiological, transcriptomic, and metabolic analysis to assess the effects of nano/microplastics on tea plants, finding impaired photosynthesis, oxidative stress, and disrupted metabolic pathways at environmentally relevant concentrations. The study highlights risks to tea crop safety and quality from plastic pollution in agricultural soils.
Calcium-mediated mitigation of aged nanoplastic-induced stress in microalgae: Insights into photosynthesis, energy metabolism, and antioxidant defense from physiological and multi-omics analyses
Scientists found that tiny plastic particles (nanoplastics) severely damage microalgae, which are important organisms used to clean wastewater before it enters our water supply. However, adding calcium to the water protected the microalgae from this plastic pollution and helped them continue removing harmful substances from wastewater. This research suggests calcium could help maintain clean water treatment systems even as plastic pollution increases in our environment.
Microplastics as emerging stressors in plants: biochemical and metabolic responses
This review examines how microplastics act as environmental stressors in plants, disrupting biochemical and metabolic processes including photosynthesis, antioxidant defenses, and nutrient uptake, with effects varying by polymer type, particle size, and concentration.
Effect of plastic pollution on freshwater flora: A meta-analysis approach to elucidate the factors influencing plant growth and biochemical markers
Meta-analysis of 43 studies found that higher concentrations of micro- and nanoplastics negatively affected aquatic plant growth while increasing protein content and antioxidant enzyme activity as a stress response. Among polymers, PVC most strongly disrupted photosynthetic pigments, and algal species were the most growth-sensitive plant group.
