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.
Phytotoxic effects of polyethylene microplastics combined with cadmium on the photosynthetic performance of maize (Zea mays L.)
Researchers studied how polyethylene microplastics combined with cadmium, a toxic heavy metal, affect photosynthesis in two varieties of maize. They found that microplastics generally worsened cadmium's negative effects on the plants' ability to capture light energy and convert it to growth, though responses differed between maize varieties. The study suggests that microplastic pollution in agricultural soils could amplify the harm caused by heavy metal contamination to crop productivity.

Researchers studied the combined effects of polyethylene microplastics and cadmium on soil properties and maize growth through pot experiments. They found that microplastics altered soil nutrient availability and, depending on size and concentration, either increased or decreased cadmium uptake by the plants. The study suggests that microplastic contamination in agricultural soils can change how crops absorb toxic heavy metals, with potential implications for food safety.
Synergistic integration of melatonin, copper nanoparticles, and Bacillus velezensis mitigates anthracnose and microplastic stress in chili: A novel eco-friendly strategy for sustainable crop protection
Researchers combined melatonin, copper nanoparticles, and a beneficial bacterium (Bacillus velezensis) to simultaneously protect chili pepper plants from both fungal disease and microplastic stress, finding the triple treatment restored photosynthesis, hormone balance, and antioxidant defenses better than any single agent alone.
Melatonin Alleviates Antimony Toxicity by Regulating the Antioxidant Response and Reducing Antimony Accumulation in Oryza sativa L.
Researchers investigated whether melatonin, a natural antioxidant compound, could help rice plants cope with toxic antimony contamination. They found that applying melatonin reduced antimony uptake, decreased oxidative damage, and improved rice growth under antimony stress conditions. The study suggests that melatonin treatments could be a practical strategy for growing rice in soils contaminated with heavy metals.
Melatonin-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.
Involvement of Nitric Oxide and Melatonin Enhances Cadmium Resistance of Tomato Seedlings through Regulation of the Ascorbate–Glutathione Cycle and ROS Metabolism
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.
Arbuscular mycorrhizal fungi enhance maize cadmium resistance and reduce translocation: Dependence on microplastics concentration
Researchers investigated how beneficial soil fungi called arbuscular mycorrhizal fungi can help maize plants resist cadmium toxicity in soils contaminated with both microplastics and heavy metals. They found that high concentrations of polyethylene microplastics worsened cadmium toxicity, but inoculation with mycorrhizal fungi significantly improved plant growth, nutrient uptake, and photosynthesis. The study suggests that these fungi could serve as a biological tool for managing crop health in soils with combined microplastic and heavy metal contamination.
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.
Interactions of microplastics and cadmium on plant growth and arbuscular mycorrhizal fungal communities in an agricultural soil
Researchers studied how polyethylene and polylactic acid microplastics interact with cadmium contamination to affect maize growth and beneficial soil fungi in agricultural soil. While polyethylene showed minimal direct plant toxicity, high doses of polylactic acid significantly reduced maize biomass, and both plastic types altered the communities of root-associated fungi. The study suggests that co-contamination of microplastics and heavy metals in farmland can jointly disrupt plant health and soil ecosystems.
Combined transcriptome and metabolome analysis revealed the toxicity mechanism of individual or combined of microplastic and salt stress on maize
Researchers studied how polystyrene microplastics combined with salt stress affect maize seedlings, finding that the combination reduced plant growth by nearly 74%, far worse than either stressor alone. Gene and metabolite analysis revealed that the combined stress severely disrupted energy production, antioxidant defenses, and hormone signaling in the plants. This is relevant to food security because microplastic-contaminated agricultural soils with high salt levels could dramatically reduce crop yields.
Melatonin counteracts polyethylene microplastics induced adreno-cortical damage in male albino rats
Researchers found that polyethylene microplastics damaged the adrenal glands of male rats, disrupting cortisol production and reducing genes needed for hormone synthesis. This is the first study to specifically examine microplastic effects on the adrenal glands, which are critical for the body's stress response. The study also showed that melatonin, a natural hormone, provided significant protection against this damage, suggesting a possible way to counteract microplastic-related endocrine disruption.
Assessing stress responses in potherb mustard (Brassica juncea var. multiceps) exposed to a synergy of microplastics and cadmium: Insights from physiology, oxidative damage, and metabolomics
Researchers found that microplastics in soil increased the amount of cadmium, a toxic heavy metal, that mustard green plants absorbed, while also reducing crop yields and photosynthesis. Higher concentrations of microplastics made more cadmium available in the soil, leading to greater accumulation of the metal in the plants. This raises food safety concerns because vegetables grown in microplastic-contaminated soil could contain higher levels of toxic metals that are harmful to human health.
Plant growth-promoting bacteria modulate gene expression and induce antioxidant tolerance to alleviate synergistic toxicity from combined microplastic and Cd pollution in sorghum
Scientists found that a beneficial soil bacterium (Bacillus sp. SL-413) can help protect sorghum plants from the combined toxic effects of microplastics and cadmium, a heavy metal. The bacterium boosted plant growth, reduced harmful reactive oxygen species by up to 27%, and reactivated genes that the pollution had shut down. This research points to a nature-based solution for helping food crops survive in microplastic-contaminated soil.
Melatonin Alleviates Intestinal Barrier Damaging Effects Induced by Polyethylene Microplastics in Albino Rats
Researchers found that polyethylene microplastics damaged the intestinal barrier in rats by causing inflammation, reducing protective mucus, and disrupting the tight junctions between gut cells. The damage was more severe at higher doses and included changes in gut bacteria composition. The study also found that melatonin treatment helped protect against these intestinal effects, suggesting potential avenues for reducing microplastic-related gut damage.
Ecotoxicological Impacts of Microplastics and Cadmium Pollution on Wheat Seedlings
Researchers investigated the combined effects of polyethylene microplastics and cadmium on wheat seedlings and found that microplastics generally reduced the antioxidant enzyme response that cadmium alone would trigger.
