| Περίληψη: | This study explores the bioinorganic potential of selenium nanoparticles (SeNPs) biosynthesized by Bacillus sp. (AKS_bp1, PQ824612) in mitigating hexavalent chromium [Cr(VI)] toxicity in chickpea (Cicer arietinum L.). SeNPs were produced via microbial reduction of sodium selenite and characterized by nanoscale size (~ 100-150 nm), negative surface charge (- 20 mV), and biomolecular capping. Under controlled hydroponic Cr(VI) exposure (0-100 ppm), SeNP treatment significantly reduced Cr accumulation in plant tissues, with decreases of 24% in roots and 45% in shoots, indicating restricted translocation and improved metal homeostasis. This suggests a Se-mediated modulation of Cr mobility within the plant system. At the physiological and biochemical levels, SeNPs alleviated Cr-induced oxidative stress, as evidenced by reductions in superoxide (65%) and hydrogen peroxide (52%) levels, along with enhanced antioxidant defense and photosystem II efficiency (a 21% increase in photochemical performance). Improved chlorophyll fluorescence and stomatal regulation further indicated restoration of cellular functionality under metal stress. Importantly, SeNPs exhibited intrinsic redox activity with catecholase-like catalytic behavior (k (© 2026. The Author(s), under exclusive licence to Springer Nature B.V.) |
