Selenium mitigates vanadium toxicity through enhanced nutrition, photosynthesis, and antioxidant defense in rice (Oryza sativa L.) seedlings.

ABSTRACT: In the current industrial scenario, vanadium (V) as a metal is of great importance but poses a major threat to the ecosystem. In the present study, the effect of a toxic concentration of V, i.e., 10 µM in the soil on growth, photosynthetic pigments, gas exchange characteristics, oxidative stress biomarkers, antioxidants machinery (enzymatic and non-enzymatic antioxidants), ions uptake, proline metabolism, and V uptake in different parts of the plant was investigated with and without the exogenous application of selenium (Se) i.e., 5 µM in V-stressed rice (Oryza sativa L.). Our results depicted that V addition to the soil significantly (P < 0.05) decreased plant growth and biomass, gas exchange attributes, and minerals uptake by O. sativa as compared to the plants grown without the addition
