Magnesium Oxide Nanoparticles (MgO-NPs) Alleviate Arsenic Toxicity in Soybean by Modulating Photosynthetic Function, Nutrient Uptake and Antioxidant Potential

The consequences of climate change, and the increased accumulation metalloids, like arsenic (As), in environment, are significantly affecting crop performance yield. Arsenic interferes with various plant biochemical physiological processes, which result diminished growth development. Magnesium oxide nanoparticles (MgO-NPs) can improve contribute to tolerance heavy metal/metalloid toxicity. During current research, efficacy MgO-NPs was assessed for lessening (As) toxicity soybean plants. In our experiment As uptake, growth, antioxidant enzyme activity, nutrient content, photochemical efficiency photosynthetic were evaluated with/without exogenous application 500 mg L−1 presence/absence 150 µM Foliar MgO-NPs, presence As, enhanced height dry weight by 17% 15% respectively, improved net rate 12.9%, stomatal conductance 13.4%, intercellular CO2 concentration 15.3% transpiration 14.7%, as well uptake photosystem II (PSII) efficiency. contrast, it decreased oxidative stress hydrogen peroxide (H2O2) lipid peroxidation (MDA). Hence, field tests may be implemented formulate use agriculture, order obtain sustainable production arsenic-contaminated soils.
