Abstract
Soil salinity is one of the major abiotic stress factors limiting the growth, development, and productivity of agricultural crops. The excessive accumulation of soluble salts in soil, particularly Na⁺ and Cl⁻ ions, induces osmotic stress, disrupts ionic homeostasis, causes oxidative stress, and reduces nutrient uptake in plants. Under these conditions, the application of biological approaches, particularly beneficial microorganisms inhabiting the plant rhizosphere, represents a promising strategy for mitigating the adverse effects of soil salinity. Silicate-solubilizing bacteria can accelerate the biological weathering of silicate minerals and potentially increase the availability of plant-accessible forms of silicon in soil. These microorganisms contribute to the dissolution of silicate minerals through the production of organic acids, ligands, exopolysaccharides, and other metabolites. Numerous studies have demonstrated the role of silicon in maintaining ionic homeostasis, regulating water relations, activating antioxidant defense systems, and enhancing plant tolerance to salt stress.
