Abstract Background Salinity stress, an escalating concern in the realm of agriculture, significantly hampers crop productivity worldwide. In recent years, nano‐fertilizers have been identified as innovative and promising avenue for improving nutrient use efficiency mitigating salt stress plants. Aims This study delves into comparative efficacy (Zn Si) their conventional sources bolstering maize's resilience against stress. Methods The hydroponic experiment was conducted to test maize plants under along with Zn Si nanoparticles (NPs) application. analysis extends impacts on ionic homeostasis, specifically focusing potassium sodium concentrations, K/Na ratio, stomatal conductance, chlorophyll content, osmotic potential (OP) within shoots roots maize. Results Nanoparticles relatively helped better compared respective bulk mode applications. Nano‐Zn treatment considerably boosts K + concentration enhanced a key physiological trait salt‐resistant species, while nano‐Si demonstrates prominent role modulating OP limiting Na accumulation higher tolerance index confirmed contribution these adjustments helping plant Conclusions Our findings confirm that application nutrients nano‐fertilizers, particularly nano‐Zn, ratio improved availability uptake plant. are also attributed adjustment facilitating water movement, thus highlighting overall agricultural related environmental issues.

In many regions of the world, K is being depleted from soils due to agricultural intensification a lack accessibility, and high cost K. Thus, there an urgent need for sustainable strategy crops in this environment. Si option mitigating stress nutritional deficiency. However, underlying effects deficiency C:N:P homeostasis still remains unknown bean plants. This species great worldwide importance. study aims evaluate whether i) modifies homeostatic balance C, N P, and, if so, ii) supply can reduce damage caused stoichiometry, nutrient use efficiency, production dry mass plants.K reduction stoichiometric ratios C:N, C:P, P:Si shoots C:Si, N:Si, roots, resulting decrease content efficiency reducing biomass production. The application K-deficient plants modified N:P, increasing loss biomass. with sufficiency, also changed only roots C P N, roots.K causes balance, viable alternative attenuate these damages, favoring growth. future perspective that agriculture underdeveloped economies restrictions on will constitute increase food security.

Mechanistic insights into the plant biostimulant activity of a novel formulation based on rice husk nanobiosilica embedded in a seed coating alginate film

Frontiers in Plant Science, Journal Year: 2024, Volume and Issue: 15

Published: May 21, 2024

Seed coating ensures the targeted delivery of various compounds from early stages development to increase crop quality and yield. Silicon alginate are known have plant biostimulant effects. Rice husk (RH) is a significant source biosilica. In this study, we coated mung bean seeds with an alginate-glycerol-sorbitol (AGS) film embedded biogenic nanosilica (SiNPs) RH, activity. After dilute acid hydrolysis ground RH in temperature-controlled hermetic reactor, resulting substrate was neutralized calcined at 650°C. The structural compositional characteristics native intermediate substrate, SiNPs, as well release soluble Si were investigated. for seed optimized using mixture design three factors. physiological properties assessed absence presence 50 mM salt added beginning. main parameters investigated growth, development, metabolic activity, reactive oxygen species (ROS) metabolism, content seedlings. results evidenced homogeneous AGS formation embedding 50-nm amorphous SiNPs having Si-O-Si Si-OH bonds, 0.347 cm3/g CPV (cumulative pore volume), 240 m2/g SSA (specific surface area). has remarkable enhancing metabolic, proton pump activities ROS scavenging seedlings under stress. study shows that can be efficiently applied, together optimized, beneficial alginate-based film, biostimulants alleviate saline stress first development.

Enhancing Soybean Salt Tolerance with GSNO and Silicon: A Comprehensive Physiological, Biochemical, and Genetic Study

International Journal of Molecular Sciences, Journal Year: 2025, Volume and Issue: 26(2), P. 609 - 609

Published: Jan. 13, 2025

Soil salinity is a major global challenge affecting agricultural productivity and food security. This study explores innovative strategies to improve salt tolerance in soybean (Glycine max), crucial crop the supply. investigates synergistic effects of S-nitroso glutathione (GSNO) silicon on enhancing max). Two cultivars, Seonpung (salt-tolerant) Cheongja (salt-sensitive), were analyzed for various physiological, biochemical, genetic traits under stress. The results showed that combined GSNO Si treatment significantly improved several key traits, including plant height, relative water content, root development, nodule numbers, chlorophyll stomatal aperture, both control stress conditions. Additionally, this optimized ion homeostasis by Na/K ratio Ca while reducing damage markers such as electrolyte leakage, malondialdehyde, hydrogen peroxide. stress-responsive compounds, proline, ascorbate peroxidase, water-soluble proteins, elevated conditions, indicating tolerance. Gene expression analysis revealed significant upregulation genes GmNHX1, GmSOS2, GmAKT1, associated with response, GmNIP2.1, GmNIP2.2, GmLBR downregulated varieties. Notably, salt-sensitive variety exhibited higher leakage oxidative compared salt-tolerant Seonpung. These findings suggest combination enhances improving physiological resilience, homeostasis, gene expression.
