"Nanophytovirology" is a potential management approach to combat plant viral diseases. Herein, the impact of foliar application CeO2 nanoparticles (CeO2-NPs) on growth, cell ultrastructure, and physiology alfalfa mosaic virus (AMV)-infected seedlings was explored at different concentrations strategies. In solar greenhouse, 20 mL CeO2-NP suspensions 50, 100, 200, 500 mg/L sprayed onto surface every other day for 9 days. As result, total volume applied per pot 100 mL. It showed that beneficial effects CeO2-NPs infected were dependent concentration period. Compared control, with before AMV infection (CeO2-NPs-BVI) greatest suppression efficacy; significantly reduced disease indices by 58.87%; improved yield, nutritional quality; increased height, dry biomass, crude protein, fat contents relative feeding value 15.17, 37.12, 18.77, 71.19, 10.09%, respectively. Moreover, CeO2-NPs-BVI maintained chloroplast quantity structure leaf cells enhanced chlorophyll content photosynthesis rate leaves 36.14 40.13%, respectively, as compared control. Mechanistically, physiology, transcriptomic analyses revealed (1) effectively mitigated AMV-induced damage, subsequently enhancing carbon fixation in photosynthetic organisms, providing sufficient energy antiviral activities maintaining growth development; (2) AMV's ability bind host receptors evade immune recognition, activating boosting systemic immunity down-regulating ABA ETH levels upregulating SA, IAA, BR levels; (3) activated antioxidative systems eliminate excess reactive oxygen species. These findings provide significant insight into highly efficient agent.

Phase-dependent hepatotoxicity of Aluminum oxide nanoparticles mediated through the intestinal microbiota

Environment International, Journal Year: 2025, Volume and Issue: unknown, P. 109398 - 109398

Published: March 1, 2025

Aluminum oxide (Al2O3) nanoparticles (NPs) are extensively utilized in the food industry for applications such as packaging, antimicrobial coatings, processing equipment, and additives. Despite their widespread use, mechanisms underlying Al2O3 NP-induced hepatotoxicity relationship between physicochemical properties toxicity remain inadequately understood. In this study, we explored hepatotoxic effects of α-Al2O3 γ-Al2O3 NPs rats subjected to oral exposure 28 days. Employing an integrated metabolomics microbiome approach, aimed elucidate potential involved. Our findings revealed distinct profiles NPs, potentially mediated by differential interactions with intestinal microbiome. exhibited reduced hepatotoxicity, evidenced minimal liver oxidative stress, which may be associated upregulation digestion-related flora Peptococcaceae Romboutsia, influencing accumulation liver. Conversely, demonstrated pronounced characterized histopathological changes elevated levels alanine aminotransferase, malondialdehyde, glutathione. This increased was correlated alterations flora, including Ruminococcaceae Exiguobacterium, affected metabolites like L-phenylalanine arachidonic acid, contributing hepatotoxicity. The results underscore importance mediating determining differences toxicities different NP phases. study provides valuable insights into toxicological impacts phases, paving way safer nanomaterial design application industry.

Magnetic Nanoparticles in Agriculture: Unraveling the Impact of Nickel Ferrite Nanoparticles on Peanut Growth and Seed Nutritional Quality

Plants, Journal Year: 2025, Volume and Issue: 14(7), P. 1011 - 1011

Published: March 24, 2025

Nanotechnology has been a source of innovation in various fields recent years, and its application agriculture attracted much attention, particularly for potential to enhance crop growth optimize nutritional quality. This study systematically investigated the effects nickel ferrite nanoparticles (NiFe2O4 NPs) on peanut (Arachis hypogaea L.) growth, nutrient dynamics, biochemical responses, highlighting their as sustainable alternatives conventional fertilizers. The results showed that an optimum concentration 50 mg/kg soil significantly improved photosynthetic efficiency, biomass accumulation, seed yield, quality, with 1000 weight total yield increasing by 12.3% 15.6%, respectively. In addition, we hypothesized NiFe2O4 NPs would activate antioxidant system increase plant resistance. According risk assessment, target hazard quotient (THQ = 0.081) is well below safety threshold 1. These findings provide strong evidence next-generation nano-fertilizers, offering dual advantage agronomic performance biosafety. However, further research needed strategies assess long-term environmental impacts.
