ClearMelatonin reduces nanoplastic uptake, translocation, and toxicity in wheat
Researchers investigated whether melatonin could reduce the harmful effects of polystyrene nanoplastics on wheat plants. They found that melatonin application significantly decreased nanoplastic uptake by roots and their transport to shoots by regulating aquaporin gene expression and activating antioxidant defense systems. The study suggests that melatonin may serve as a protective agent to help mitigate nanoplastic toxicity in crops.
Exogenous Melatonin Application Alleviates Microplastics and Cadmium‐Induced Phytotoxicity in Maize ( Zea mays L.) Plants: Insights From Physiological and Metabolomic Analyses
Researchers investigated whether exogenous melatonin could alleviate the combined phytotoxicity of microplastics and cadmium in maize plants. The study found that melatonin application reduced oxidative damage and improved plant growth under co-contamination stress, suggesting that melatonin may serve as a biostimulant to help crops cope with the increasingly common co-occurrence of microplastics and heavy metals in agricultural soils.
Melatonin Defends Against the Oxidative Stress by Preventing the Uptake of Nanoplastics and Activating the Antioxidant System in Paeonia ostii.
Scientists found that melatonin (a natural hormone) can protect plants from tiny plastic particles by blocking them from entering plant cells and reducing harmful damage inside the plant. This matters because these microscopic plastics are spreading everywhere in our environment and getting into our food chain. While this study only looked at plants, it suggests melatonin might help protect living things from plastic pollution - though more research is needed to know if this applies to humans.
Impact of Titanium Dioxide Nanoparticles on Agricultural Crops Performance: A Review of Efficacy and Mechanisms
This paper is not relevant to microplastics research; it reviews the effects of titanium dioxide nanoparticles on agricultural crop performance, focusing on photosynthesis enhancement and antimicrobial protection rather than plastic pollution.
Chitosan nanoparticles alleviate nanoplastics toxicity by modulating polyamine metabolism and re-establishing redox homeostasis in maize seedlings
Researchers found that chitosan nanoparticles can alleviate the toxic effects of polystyrene nanoplastics on maize seedlings by modulating polyamine metabolism and restoring redox balance. The treatment significantly reduced nanoplastic accumulation in plant tissues by 32-56%, suggesting that this sustainable polymeric material could help protect crops from nanoplastic contamination in agricultural settings.
Reclaiming multi-contaminated soil: melatonin alleviates cadmium and microplastic toxicity to restore rice growth and yield
Researchers investigated whether melatonin could mitigate the combined toxicity of cadmium and microplastics in agricultural soils to restore rice growth and yield. The study found that melatonin treatment modulated plant physiological function, reduced cadmium uptake, and improved soil properties, offering a promising approach to help crops withstand multi-contaminant stress from both heavy metals and microplastics.
Titanium dioxide nanoparticles enhance the detrimental effect of polystyrene nanoplastics on cell and plant physiology of Vicia lens (L.) Coss. & Germ. seedlings
Combined exposure of Vicia lens seedlings to polystyrene nanoplastics and titanium dioxide nanoparticles caused greater physiological and cellular damage than either contaminant alone, suggesting synergistic toxicity at the plant level.
Strigolactones alleviate the toxicity of polystyrene nanoplastics (PS-NPs) in maize (Zea mays L.)
Researchers found that a natural plant hormone called strigolactone helped protect maize plants from the toxic effects of polystyrene nanoplastics by reducing how much plastic accumulated in the roots. The hormone activated the plant's antioxidant defenses and changed the expression of genes related to stress response and hormone signaling. While focused on plants, this research matters for food safety because it could lead to agricultural practices that reduce how much microplastic contamination ends up in crops that people eat.
Antagonistic effect of polystyrene nanoplastics on cadmium toxicity to maize (Zea mays L.)
Researchers studied the combined effects of polystyrene nanoplastics and cadmium on maize plants and found that nanoplastics actually reduced cadmium toxicity. The study suggests that nanoplastics can adsorb cadmium and limit its uptake by plant roots, though both contaminants individually reduced plant growth and triggered oxidative stress responses.
Melatonin mitigates polystyrene nanoplastics-induced impairment of oocyte maturation in mice
Researchers found that polystyrene nanoplastics impair egg cell maturation in mice by causing excessive oxidative stress, mitochondrial dysfunction, and disrupting the structural machinery needed for proper cell division. They then tested whether melatonin could counteract these effects and found that melatonin treatment significantly alleviated the damage by restoring mitochondrial function and reducing oxidative stress. The study suggests that melatonin may offer a protective strategy against nanoplastic-induced reproductive harm.
Unraveling the adverse Impacts of Nano-scale Carbon Exposure on Nitrogen Metabolism during Early Seedling Establishment in Zea mays L. Roots

Melatonin Alleviates the Damage of Polystyrene Microplastics to Porcine Oocytes by Reducing Oxidative Stress and Mitochondrial Damage, and Regulating Autophagy and Apoptosis Levels
Researchers investigated whether the antioxidant melatonin could protect porcine oocytes from damage caused by polystyrene microplastics. The study found that microplastics at 30 micrograms per milliliter significantly impaired oocyte maturation, but melatonin treatment helped alleviate this damage by reducing oxidative stress, protecting mitochondrial function, and regulating autophagy and cell death pathways.
Toxicity effects of nanoplastics on soybean (Glycine max L.): Mechanisms and transcriptomic analysis
Researchers exposed soybean plants to polystyrene nanoplastics and observed inhibited stem and root growth, increased oxidative stress, and disrupted photosynthesis. Transcriptomic analysis revealed that nanoplastics altered the expression of genes involved in plant stress responses, hormone signaling, and metabolic pathways. The study suggests that nanoplastic contamination in agricultural soils could negatively affect crop growth and yield at the molecular level.
Toxicological effects and molecular metabolic of polystyrene nanoplastics on soybean (Glycine max L.): Strengthening defense ability by enhancing secondary metabolisms
Researchers exposed soybean seedlings to polystyrene nanoplastics and found that the tiny particles were absorbed by the roots and transported throughout the plant. The nanoplastics caused oxidative stress and slowed growth, though the plants activated defense mechanisms through secondary metabolism. This is concerning because crops that absorb nanoplastics could transfer them to humans through the food supply.

Researchers found that nano-titanium dioxide alleviated the growth inhibition and oxidative stress that polylactic acid microplastics caused in radish roots, with transcriptomic and metabolomic analysis revealing nano-TiO2 stimulated the phenylpropanoid biosynthesis pathway to enhance the plant's antioxidant defenses.
Membrane Lipid Remodeling Modulated Maize Response to Environmentally Relevant Atmospheric Nanoplastics
Researchers exposed maize leaves to polystyrene nanoplastics with different surface modifications at environmentally relevant doses and found that amino-modified particles caused the strongest growth inhibition. All nanoplastics entered the leaves through stomata and accumulated in a dose-dependent manner, significantly suppressing the production of 31 membrane lipids involved in cell structure and signaling. The study reveals that atmospheric nanoplastics can disrupt membrane lipid metabolism in crops, providing molecular-level evidence of how airborne plastic particles may affect agricultural plants.
