With the extensive utilization of plastic products, microplastics/nanoplastics (MPs/NPs) contamination not only poses a global hazard to environment, but also induces new threat growth development and nutritional quality plantation agricultural products. This study thoroughly examines behavior MPs/NPs, including their sources, entry routes into plants, phytotoxicity under various biotic abiotic stresses (e.g., salinity, polycyclic aromatic hydrocarbons, heavy metals, antibiotics, plasticizers, nano oxide, naturally occurring organic macromolecular compounds, invasive Botrytis cinerea mycorrhizal fungi.) controlling strategies. MPs/NPs in systems mainly originate from mulch, sewage, compost fertilizer, municipal solid waste, pesticide packaging materials, etc. They enter plants through endocytosis, apoplast pathways, crack-entry modes, leaf stomata, affecting phenotypic, metabolic, enzymatic, genetic processes such as seed germination, metabolism, photosynthesis, oxidative stress antioxidant defenses, fruit yield nutrient quality, cytotoxicity genotoxicity. can interact with other environmental stressors, resulting synergistic, antagonistic, or neutral effects on phytotoxicity. To address these challenges, this review highlights strategies mitigate toxicity, novel green biodegradable plastics, plant extraction immobilization, exogenous regulator interventions, porous nanomaterial modulation, biocatalysis enzymatic degradation. Finally, identifies current limitations future research directions critical field.

Опубликована: Март 24, 2025

Nanoparticles (NPs) exhibit the potential to enhance plant tolerance organic pollutant stress, but how they drive endogenous molecules detoxify contaminants remains be further investigated. This study clarified modulatory mechanisms by which foliar or root application of biosynthesized titanium oxide NPs (g-nTiO2) alleviated atrazine (ATZ) toxicity Lactuca sativa L. Compared with ATZ-alone group, 10 mg/L g-nTiO2 intensified light-harvesting, photoelectron transfer, and reduced oxidative damage, thereby improving growth inducing metabolic reprogramming. Specifically, activated pathways related energy supply defense detoxification, while stabilizing membrane lipid nitrogen metabolism. Furthermore, modulation biomarkers involved in balancing cellular homeostasis stimulating ultimately boosted lettuce resistance ATZ physiological performance. Molecular docking analysis revealed that enhanced Phase II metabolism glutathione amino acids through increasing detoxification enzyme activities 23–44%, confirmed driving role alleviating phytotoxicity lettuce. Collectively, these findings provide a prospective nanoenabled strategy for mitigating crop sensitivity pesticide residues safe sustainable agricultural production.

Abstract The use of nanoparticles has emerged as a popular amendment and promising approach to enhance plant resilience environmental stressors, including salinity. Salinity stress is critical issue in global agriculture, requiring strategies such salt-tolerant crop varieties, soil amendments, nanotechnology-based solutions mitigate its effects. Therefore, this paper explores the role plant-based titanium dioxide (nTiO 2 ) mitigating effects salinity on soybean phenotypic variation, water content, non-enzymatic antioxidants, malondialdehyde (MDA) mineral contents. Both 0 30 ppm nTiO treatments were applied plants, along with six salt concentrations (0, 25, 50, 100, 150, 200 mM NaCl) combined effect decreased chlorophyll carotenoids which results significant decrement total fresh dry weights. Treatment control NaCl treated plants by showed improvements vegetative growth increasing chlorophyll, content carbohydrates. Additionally, application boosted accumulation contributing reduced oxidative damage (less MDA). Notably, it also mitigated Na + while promoting K Mg ++ uptake both leaves roots, essential for maintaining ion homeostasis metabolic function. These suggest that potential improve tolerance proper balance reducing MDA level, offering strategy management saline-prone areas.
