Unfavorable environmental conditions pose a major barrier to sustainable agriculture. Among the various innovative strategies developed protect plants from abiotic stress, use of phytohormones and nanoparticles as “stress mitigators” has emerged one most important promising approaches. The objective this study was observe protective role melatonin (Mel) silicon oxide (SiO-NPs) in rice ( Oryza sativa L.) seedlings under cadmium (Cd) stress. Rice have reduced growth phytochemical attributes when grown Cd-contaminated (0.8 mM) pots. Seedlings Cd stress had 38% less shoot length (SL), 53% total soluble sugar (TSS) 57% protein content. However, superoxide dismutase (SOD), hydrogen peroxide (H 2 O ) malondialdehyde (MDA) increased by 51%, 37% 34%, respectively, Beside this, activities such peroxidase (POX) also elevated subjected with Cd-stress. In contrast, Mel (100 µm) foliar spray SiO-NPs mg/L) root dipping oxidative reducing reactive oxygen species (ROS) generation. Furthermore, application and/or significantly activity antioxidative enzymes that scavenge ROS. combined growth, gas exchange photosynthetic attributes, chlorophyll value, It causes alleviation SOD, CAT POX 73%, 62% 65%, respectively.

Selenium improves wheat antioxidant capacity, photosynthetic capacity, and growth under cadmium stress

Photosynthetica, Journal Year: 2024, Volume and Issue: 62(3), P. 232 - 239

Published: July 30, 2024

Cadmium stress (CS) induced the peroxide damage and inhibited wheat photosynthetic capacity growth. Compared to CS, selenium (Se) application plus CS bolstered chlorophyll carotenoid contents, rate, maximum photochemical efficiency of PSII, quantum yield PSII photochemistry, quenching, superoxide dismutase, catalase, ascorbate peroxidase, glutathione reductase, L-galactono-1,4-lactone dehydrogenase, gamma-glutamylcysteine synthetase activities, ascorbic acid AsA/dehydroascorbic GSH/oxidized glutathione, decreased nonphotochemical quenching (q_N), antioxidant biomarkers malondialdehyde hydrogen electrolyte leakage (EL). At same time, Se alone declined q_N EL, augmented rest aforementioned indexes. Our research implied that upregulated wheat's capacity. In this way, improved performance growth, especially for 10 μM sodium selenite (Na₂SeO₃). Consequently, Na₂SeO₃ may be considered a useful exogenous substance reinforce cadmium tolerance.

γ-aminobutyric acid enhances the antioxidant defense system and photosynthetic performance of wheat seedlings under cadmium stress

Plant Soil and Environment, Journal Year: 2024, Volume and Issue: 70(9), P. 590 - 599

Published: Aug. 6, 2024

In this paper, I elucidated the influence of γ-aminobutyric acid (GABA) on wheat cadmium (Cd) tolerance. Research results manifested that Cd stress increased superoxide dismutase, catalase, peroxidase, ascorbate peroxidase and glutathione activities, ascorbic (AsA) (GSH) contents. However, decreased AsA/ dehydroascorbic (DHA) GSH/oxidised (GSSG) ratios, inhibited photosynthetic performance plant growth. Compared to alone, GABA plus improved tolerance by increasing activities above antioxidant enzymes, AsA GSH contents, AsA/DHA GSH/GSSG ratios. Meanwhile, compared with also enhanced improving chlorophyll (Chl) carotenoid (Car) contents Car/Chl ratio, rate, transpiration stomatal conductance, intercellular carbon dioxide concentration, Chl fluorescence parameters maximum photochemical efficiency PSII, quenching, nonphotochemical quenching quantum PSII photochemistry, which further promoted height biomass. control, alone indicators. Current suggested can be applied as an anti-cadmium agent in production practice.
