Metalloid Nanomaterials Alleviate Arsenic Phytotoxicity and Grain Accumulation in Rice: Mechanisms of Abiotic Stress Tolerance and Rhizosphere Behavior

Environmental Science & Technology, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 23, 2025

Nanoenabled agriculture technology exhibits potential in reducing arsenic uptake rice; however, a systematic understanding of the rice-soil-microorganism process nanomaterials (NMs) is lacking. Soil amendment metalloid NMs, including SiO2, hydroxyapatite, S0, and Se0 at 10-100 (0.1-5.0 for Se NMs) mg/kg, increased rice biomass by 76.1-135.8% arsenic-contaminated soil (17.0 mg/kg) decreased accumulation plant tissues 9.3-78.2%. The beneficial effects were nanoscale-specific NMs type- concentration-dependent; 5 mg/kg showed greatest growth promotion decrease As accumulation. Mechanistically, (1) optimized bacterial community structure, enhancing abundance arsM 104.2% subsequently increasing methylation 276.1% rhizosphere compared to arsenic-alone treatments; (2) metabolomic analyses that upregulated biosynthesis pathway abscisic acid, jasmonic glutathione, with subsequent downregulation transporter-related gene expression roots 42.2-73.4%, decreasing formation iron plaque 87.6%, detoxification 50.0%. Additionally, significantly enhanced arsenic-treated yield 66.9-91.4% grain nutritional quality. This study demonstrates excellent an effective sustainable strategy increase food quality safety.

Micro/Nanoplastics in plantation agricultural products: behavior process, phytotoxicity under biotic and abiotic stresses, and controlling strategies

Journal of Nanobiotechnology, Journal Year: 2025, Volume and Issue: 23(1)

Published: March 21, 2025

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.

Published: Sept. 5, 2024

To assess the ecological risk of microplastics (MPs) in agricultural systems, it is critical to simultaneously focus on MP-mediated single-organism response and different trophic-level organism interaction. Herein, we placed earthworms soils contaminated with concentrations (0.02% 0.2% w/w) polyethylene (PE) polypropylene (PP) MPs investigate effect tomato against
