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.
Exogenously Applied Sodium Nitroprusside Alleviated Cadmium Toxicity in Different Aromatic Rice Cultivars by Improving Nitric Oxide Accumulation and Modulating Oxidative Metabolism
Researchers investigated whether spraying sodium nitroprusside, a compound that releases nitric oxide, could help aromatic rice plants cope with cadmium-contaminated soil. They found that the treatment reduced oxidative stress markers in the plants and improved photosynthesis, yield, and grain quality across three rice varieties. The study suggests that nitric oxide supplementation may offer a practical approach for growing rice more safely in heavy metal-polluted agricultural areas.
Effects of urban atmospheric particulate matter on higher plants using Lycopersicon esculentum as model species
Tomato plants exposed to aqueous extracts of urban atmospheric particulate matter showed dose-dependent reductions in biomass and chlorophyll content, with higher doses causing clear phytotoxic effects and protein content paradoxically increasing at intermediate doses, suggesting that PM-associated nutrient content initially offsets chemical stress at lower concentrations.
Melatonin enhances salt tolerance in sorghum by modulating photosynthetic performance, osmoregulation, antioxidant defense, and ion homeostasis
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.

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.
Sciadopitysin attenuates paraquat induced renal toxicity by modulating Nrf2/Keap-1 pathway in male albino rats
Researchers investigated whether the plant compound sciadopitysin could protect against kidney damage caused by the herbicide paraquat in rats. They found that sciadopitysin significantly reduced oxidative stress and inflammation in the kidneys by activating the Nrf2/Keap-1 protective pathway. The study suggests that natural biflavonoid compounds may help mitigate organ damage from toxic environmental chemical exposures.
Brassinolide as potential rescue agent for Pinellia ternata grown under microplastic condition: Insights into their modulatory role on photosynthesis, redox homeostasis, and AsA-GSH cycling
Researchers found that microplastic stress suppresses growth and photosynthesis in the medicinal plant Pinellia ternata while paradoxically boosting secondary metabolites, and that brassinolide treatment restores plant height and biomass by improving photosynthesis, antioxidant enzyme activity, and the ascorbate-glutathione cycle.
RETRACTED ARTICLE: Sciadopitysin mitigates spermatological and testicular damage instigated by paraquat administration in male albino rats
Researchers evaluated whether the flavonoid sciadopitysin could protect against testicular damage caused by paraquat herbicide in rats. The study found that paraquat exposure significantly increased oxidative stress markers and sperm abnormalities, while sciadopitysin treatment helped mitigate these effects by restoring antioxidant enzyme activity. Note: this article has been retracted by the publisher.
Impacts of root exudates on the toxic response of Chrysanthemum coronarium L. to the co-pollution of nanoplastic particles and tetracycline
Researchers grew Chrysanthemum coronarium under combined nanoplastic and tetracycline exposure and found synergistic oxidative damage and biomass reduction, with root exudates containing malic, oxalic, and formic acids found to partially alleviate toxicity by reducing reactive oxygen species levels.
Bisphenol A contamination in irrigation water compromises tomato (Solanum lycopersicum) performance and food safety through oxidative and molecular stress pathway
Tomato plants irrigated with bisphenol A (BPA)-contaminated water exhibited oxidative stress, disrupted hormonal signalling, and reduced fruit quality. The findings indicate that BPA in reclaimed irrigation water can compromise both crop health and food safety through molecular stress pathways.
