ClearMelatonin-Mediated Abiotic Stress Tolerance in Plants
This review examines how melatonin, a molecule found in all living organisms, helps plants cope with environmental stresses like drought, extreme temperatures, salinity, and heavy metal contamination. Researchers found that melatonin works by neutralizing harmful reactive oxygen species and activating plant defense pathways. The study suggests that melatonin-based treatments could help improve crop resilience in the face of increasing environmental challenges, including soil pollution.

Researchers found that melatonin and nitric oxide work together to enhance cadmium stress tolerance in tomato seedlings, with melatonin acting partly through nitric oxide signaling to reduce oxidative damage and support seedling growth under heavy metal stress.
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.
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.
Interpreting the potential of biogenic TiO2 nanoparticles on enhancing soybean resilience to salinity via maintaining ion homeostasis and minimizing malondialdehyde
Researchers found that titanium dioxide nanoparticles derived from plants helped soybean crops tolerate salt stress by improving water retention, boosting antioxidant defenses, and keeping beneficial minerals like potassium in balance — offering a potential tool for farming in salt-affected soils.
Exogenous spermine alleviates the negative effects of combined salinity and paraquat in tomato plants by decreasing stress-induced oxidative damage
Exogenous spermine application reduced leaf damage and improved photosynthetic function and growth of tomato plants under combined salinity and paraquat herbicide stress, with the protective effect attributed to decreased hydrogen peroxide and malondialdehyde accumulation.
Melatonin Supplementation during In Vitro Maturation of Porcine Oocytes Alleviates Oxidative Stress and Endoplasmic Reticulum Stress Induced by Imidacloprid Exposure
Researchers found that the neonicotinoid insecticide imidacloprid adversely affected porcine oocyte maturation by increasing oxidative stress, endoplasmic reticulum stress, and apoptosis. The study demonstrated that melatonin supplementation during in vitro maturation was able to restore oocyte quality and embryo development outcomes compromised by imidacloprid exposure, suggesting melatonin has protective properties against pesticide-induced reproductive toxicity.
Titanium dioxide nanoparticles alleviates polystyrene nanoplastics induced growth inhibition by modulating carbon and nitrogen metabolism via melatonin signaling in maize
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.

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.
