Modulations of wheat growth by selenium nanoparticles under salinity stress

Abstract

Salinity stress is a prominent environmental factor that presents obstacles to the growth and development of plants. When the soil contains high salt concentrations, the roots face difficulties in absorbing water, resulting in water deficits within the plant tissues. Consequently, plants may experience inhibited growth, decreased development, and a decline in biomass accumulation. The use of nanoparticles has become a popular amendment in recent times for the alleviation of salinity stress. The study investigated the biological approach for the preparation of Se nanoparticles (NP) and their effect on the growth of wheat plants under saline conditions. The leaf extract of lemon (Citrus limon L.) was used for the green synthesis of selenium nanoparticles (Se-NPs). The synthesized NPs were characterized by X-ray diffraction (XRD) and Fourier-transform infrared spectroscopy (FTIR) and were applied foliar in the range of 0.01%, 0.05% and 0.1% on wheat plants. Results showed that 0.1% SeNP alone exhibited a significantly higher yield per plant, biomass per plant, 1000 grains weight, chlorophyll a, chlorophyll b and total chlorophyll over the SS (salt stress) control. A significant decline in MDA and H2O2 also validated the effectiveness of 0.1% SeNP over the SS control.

Phytofabricated gold nanoparticles as modulators of salt stress responses in spinach: implications for redox homeostasis, biochemical and physiological adaptation

“…In this study, S-AuNPs supplementation significantly improves the proline and flavonoid contents (Figures 5F, 7D); aiding in osmotic adjustment and safeguarding sub-cellular structures under salt stress. Similar results under salinity by NPs application were reported in tomato (Faizan et al, 2021), pearl millet (Khan et al, 2020) and wheat (Zafar et al, 2024).…”

“…In this context, the application of nanotechnology, specifically employing metals nanoparticles (NPs) offers a remedy for reducing controlling AsA-GSH cycle enzymes, and impacting gene expression (Al-Khayri et al, 2021;I. Khan et al, 2020;Zafar et al, 2024). In specific, gold nanoparticles (AuNPs) has been recognized as the most considered metallic NPs, owing to their stability, resistance to oxidation, antimicrobial characteristics, and low toxicity (Balkrishna et al, 2023;P.…”

“…Many studies show that nanoparticles (NPs) can mitigate salt stress in various plant species by regulating hormones, boosting antioxidant enzymes, balancing ions, controlling AsA-GSH cycle enzymes, and impacting gene expression ( Al-Khayri et al., 2021 ; I. Khan et al., 2020 ; Zafar et al., 2024 ). In specific, gold nanoparticles (AuNPs) has been recognized as the most considered metallic NPs, owing to their stability, resistance to oxidation, antimicrobial characteristics, and low toxicity ( Balkrishna et al., 2023 ; P. V. Noruzi, 2015 ; Kumar et al., 2019 ).…”

Combined effect of gallic acid and zinc ferrite nanoparticles on wheat growth and yield under salinity stress

“…Its impact includes a 10–25% crop yield reduction and, in severe cases, desertification 6 . Salinity affects plant growth by inducing osmotic stress, ionic toxicity, and nutrient deficiencies, impacting various cellular processes and photosynthesis 1 , 7 – 9 . This stress generates reactive oxygen species (ROS), causing significant damage to plant membranes 10 – 12 .…”
