As a light rare earth element, Sm and Sm2O3 are widely used in various fields such as electronics, chemistry, medicine. Their distribution the environment, accumulation biological organisms exposure through medicinal pathways have attracted increasing public attention. It is crucial to clarify impact of on human health. In this study, we applied 24 h post-fertilization (hpf) zebrafish embryos investigated toxic effects mechanisms Sm2O3. The results showed that induced developmental abnormalities embryos, prominent pericardial swelling, slight curvature spine, decreased body length. incidence significantly increased. scanning electron microscopy transmission accumulated shortening or disappearance microcrest skin cells. Lyz-fish system demonstrated macrophages migrated skin, suggesting caused damage. Laser confocal revealed heart ventricles exhibited compensatory ventricular atrophy, abnormal rates. Acridine orange (AO) staining obvious green fluorescence. Embryos proteins at 96 hpf were extracted after treatment, revealing anti-apoptosis bcl-2 protein with an increase concentration. caspase-3 apoptosis executioner also concentration-dependent expression, indicating promotes cardiac tissue DCFH-DA significant reactive oxygen species (ROS) hearts brains zebrafish. summary, ROS activated apoptotic thereby inducing exhibiting toxicity. This study 3-day resulted edema, length reduction, macrophage migration, shortened micro-ridges Notably, anomalies included arrhythmia, which correlated elevated levels signals. Mechanistically, promoted downregulation Bcl-2 upregulation expression. These findings collectively reveal induces toxicity via activation caspase-dependent pathways, highlighting its potential hazards early vertebrate development.

Abstract Nanoparticles have demonstrated significant potential in reducing the negative impacts of abiotic stress on plants and improving agricultural productivity. Temperature, salt, drought, heavy metals can hinder plant growth crop yields. Nanoparticles, mainly metal oxide nanoparticles been found to enhance resilience mitigate by affecting physiological molecular processes. Studies shown that improve growth, biomass, chlorophyll content, antioxidant production. They also nutrient absorption, regulate osmotic balance, activate defense mechanisms. like zinc (ZnO), silicon (Si), iron (FeO) effective mitigating salt stress. In contrast, manganese (Mg) titanium dioxide (TiO 2 ) promise alleviating drought Additionally, reduce toxicity heat tolerance. However, using agriculture requires careful consideration their risks environmental impact. provide a promising opportunity for enhancing sustainable practices face climate change food security challenges. By leveraging nanotechnology, we farm productivity secure resources future generations. Graphical abstract

Drought stress is one of the most important environmental constraints that negatively affect growth and production crops worldwide. Recently, nanotechnology has been increasingly used to improve tolerance plants exposed abiotic stresses such as drought. The present study was designed investigate moderating effect cerium oxide nanoparticles (CeO2 NPs) on alleviating drought for apple cv. 'Red Delicious' M9 rootstock. caused a significant increase in CAT, GPX, APX, SOD enzyme activities compared control plants. decreased content macro microelements, application CeO2 NPs led changes these elements under stress. significantly reduced chlorophyll damage high levels. In addition, they alleviated by drought, which shown lower levels MDA EL. When were during stress, greatly increased abscisic acid indole-3-acetic hormone. response expression DREB1A DREB1E genes increased. use stressful non-stressful conditions had positive improving studied traits enhancing nutrient Taken together, findings suggest can be promising stress-reducing agents apples. Therefore, understanding mechanisms global horticulture role essential developing improved, drought-tolerant adoption measures deal with changing climatic conditions.
