Silicon nanoparticles (SiNPs) have emerged as multifunctional tools in sustainable agriculture, demonstrating significant efficacy promoting crop growth and enhancing plant resilience against diverse biotic abiotic stresses. Although their ability to strengthen antioxidant defense systems activate systemic immune responses is well documented, the fundamental mechanisms driving these benefits remain unclear. This review synthesizes emerging evidence propose an innovative paradigm: SiNPs remodel redox signaling networks stress adaptation by forming protein coronas through apoplastic adsorption. We hypothesize that extracellular may elevate reactive oxygen species (ROS) levels adsorbing inhibiting enzymes, thereby intracellular buffering capacity activating salicylic acid (SA)-dependent pathways. Conversely, smaller infiltrating symplastic compartments risk oxidative damage due direct suppression of cytoplasmic systems. Additionally, indirectly influence heavy metal transporter activity state regulation broadly modulate physiological functions via transcription factor regulatory networks. Critical knowledge gaps persist regarding dynamic composition under varying environmental conditions transgenerational impacts. By integrating existing SiNPs, this provides insights potential strategies for developing novel agrochemicals stress-resistant crops.

In the pursuit of sustainable development, nanotechnology provides effective solutions for enhancing agricultural productivity. Nanomaterials (NMs) can be in increasing plant abiotic and biotic stress tolerance. Understanding nanoparticles (NPs)-plant interaction is essential to identify potential NPs growth stimulation phytotoxicity risks. Therefore, this study aimed evaluate effects biologically synthesized silver (AgNPs) from Fusarium solani IOR 825 on Zea mays. Furthermore, effect AgNPs oxidative antioxidant response was assessed. were efficiently F. characterized physicochemical properties using transmission electron microscopy (TEM), nanoparticle tracking analysis (NTA), dynamic light scattering (DLS), X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy measurement Zeta potential. at concentrations 32, 128, 512 µg mL-1 used pre-sowing treatment maize grains inhibit microbial pathogens present their surface. Sterilized cultivated 14 days plantlet development. Subsequently, germination percentage (%G), mean time (MGT), rate index (GRI), fresh dry weight (FW DW), Ag content organs total chlorophyll analyzed. Hydrogen peroxide (H2O2) malondialdehyde (MDA) determined leaves, roots, stems, caryopses assess stress. The antioxidative system studied by determining glutathione (GSH+GSSG) ascorbate (ASC) contents as well catalase (CAT), superoxide dismutase (SOD), peroxidase (POX), (APX) activities. spherical small [TEM average diameter 22.97 ± 9.4 nm, NTA size 43 36 DLS hydrodynamic diameters 27.44 nm (14%) 108.4 (86%)]. revealed that negatively charged [-19.5 mV (61.3%) -2.93 (38.6%)]. diffractogram confirmed presence a face-centered cubic structure crystalline AgNPs, while FTIR spectra showed biomolecules results dose-dependent growth. increase length plants treated with concentration noted. all tested (32, mL-1) resulted increased leaves. Reduced observed highest (512 mL-1). decreased H2O2 levels organs, except stem where oxidant's level increased. MDA unaffected which raised its ASC roots caryopses, respectively. impact SOD activity, roots. CAT activity There minor POX APX lowest (32 inhibits maize-borne pathogens, without any negative content. Moreover, it does not provoke However, may affect cellular redox systems when higher (128 are used. indicate use biogenically agriculture through crop-safe approach eliminate production efficiency.
