Summary

Researchers found that titanium dioxide nanoparticles can help protect maize plants from the growth-inhibiting effects of polystyrene nanoplastics. The protective mechanism works through the plant hormone melatonin, which regulates carbon and nitrogen metabolism when the nanoparticles are present. The study suggests that certain nanoparticles could potentially be used as agricultural tools to help crops cope with nanoplastic contamination in soil.

Polymers

Taken together, our data show that melatonin is involved in Nano-TiO2-induced growth promotion in maize through the regulation of carbon and nitrogen metabolism.

Melatonin 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.

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.
