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.

Exogenous melatonin application was found to enhance salt tolerance in sorghum by improving photosynthetic performance and modulating antioxidant responses during salt stress. The findings suggest melatonin could be a practical tool for improving crop resilience under salinity conditions.
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.
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.

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 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.
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.
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.
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.
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 induces endoreduplication through oxidative DNA-damage triggering lateral root formation in onions
This study found that melatonin triggers lateral root formation in onions by inducing DNA damage and endoreduplication. Plant hormone research is relevant to microplastics because microplastics in soil can disrupt plant hormone signaling and root development in food crops.
Ectopic Expression of AeNAC83, a NAC Transcription Factor from Abelmoschus esculentus, Inhibits Growth and Confers Tolerance to Salt Stress in Arabidopsis
Researchers found that the NAC transcription factor AeNAC83 from okra inhibits plant growth while conferring salt stress tolerance in Arabidopsis, with gene silencing increasing biomass but reducing salt resistance, revealing a growth-stress tolerance trade-off mediated by this transcription factor.

Researchers investigated the physiological, biochemical, and transcriptomic responses of pea sprouts to high salinity stress, analyzing the ascorbic acid-glutathione cycle, endogenous hormone levels, metabolite profiles, and gene expression patterns. The study revealed coordinated redox-metabolic adjustments and transcriptome reprogramming that mediate ionic stress tolerance in this nutrient-rich crop.
Deciphering Pesticide Stress Responses in Rice Through Integrated Multi-Omic Assessment
This review synthesizes research on how pesticide exposure affects rice plants at the molecular level, drawing on transcriptomic, proteomic, and metabolomic studies. Researchers found that pesticides trigger detoxification enzymes, alter antioxidant defenses, and reprogram metabolic pathways in rice. The study highlights how integrating multiple omics approaches can provide a more complete picture of pesticide stress responses in crops.
