Published: Sept. 8, 2023

Abstract Drought stress remains one of the most detrimental environmental constraints that hampers plant growth and development resulting in reduced yield leading to economic losses. Studies have highlighted beneficial role carbon-based nanomaterials (NMs) such as multiwalled carbon nanotubes (MWNTs), single-walled (SWNTs), graphene, fullerene, metal-based nanoparticles (NPs) (Ag, Au, Cu, Fe 2 O 3 , TiO ZnO) plants under unfavorable conditions drought. NPs help cope with drought by improving indices enhancing biomass. It improves water nutrient uptake utilization. helps retain altering cell walls regulating stomatal closure. The photosynthetic parameters NP-treated reportedly improved increase pigment content rate photosynthesis. Due NP exposure, activation enzymatic nonenzymatic antioxidants has improved. These play a significant defense system against stress. reported accumulation osmolytes secondary metabolites. Osmolytes scavenge reactive oxygen species, which can cause oxidative plants. Secondary metabolites are involved retention process, thus coping strategies deleterious effects alleviated reducing malondialdehyde from lipid peroxidation.

Response of Maize Seedlings to Silicon Dioxide Nanoparticles (SiO2NPs) under Drought Stress

Plants, Journal Year: 2023, Volume and Issue: 12(14), P. 2592 - 2592

Published: July 8, 2023

Recently, the use of nanofertilizers has received a great deal attention in managing plants under biotic and abiotic stresses. However, studies that elucidate role silicon dioxide nanoparticles (SiO2NPs) regulating maize tolerance to drought stress are still at early stages development. In this study, were treated with SiO2NPs (0.25 g/L as foliar spray) displayed considerable improvement growth indices, despite being subjected stress. addition, action led rise levels chlorophylls, proline, cell membrane integrity, leaf water content, antioxidant enzymes (superoxide dismutase (SOD), catalase (CAT), guaiacol peroxidase (G-POX)). contrast, an inverse trend was seen oxidative injury, total amount soluble sugars, activity ascorbate (APX). At same time, carotenoids unaffected SiO2NPs-treated non-treated The results molecular investigation conducted using qRT-PCR showed relative expression D2 protein photosystem II (PsbD) elevated response stress, while osmotic-like (OSM-34) aquaporin (AQPs) downregulated This research could pave way for further investigations into how boost plant resistance
