The effect of exogenous calcium (Ca) on hydroponically grown rice seedlings was studied under arsenic (As) stress by investigating the antioxidant and glyoxalase systems. Fourteen-day-old rice (Oryza sativaL. cv. BRRI dhan29) seedlings were exposed to 0.5 and 1 mM Na2HAsO4alone and in combination with 10 mM CaCl2(Ca) for 5 days. Both levels of As caused growth inhibition, chlorosis, reduced leaf RWC, and increased As accumulation in the rice seedlings. Both doses of As in growth medium induced oxidative stress through overproduction of reactive oxygen species (ROS) by disrupting the antioxidant defense and glyoxalase systems. Exogenous application of Ca along with both levels of As significantly decreased As accumulation and restored plant growth and water loss. Calcium supplementation in the As-exposed rice seedlings reduced ROS production, increased ascorbate (AsA) content, and increased the activities of monodehydroascorbate reductase (MDHAR), dehydroascorbate reductase (DHAR), catalase (CAT), glutathione peroxidase (GPX), superoxide dismutase (SOD), and the glyoxalase I (Gly I) and glyoxalase II (Gly II) enzymes compared with seedlings exposed to As only. These results suggest that Ca supplementation improves rice seedlings tolerance to As-induced oxidative stress by reducing As uptake, enhancing their antioxidant defense and glyoxalase systems, and also improving growth and physiological condition.

In the present study, the nine cultivars namely NDR-3112, Swarn Sub-2, Pusa-sugandha, IPB-1, Pant-4, Pant-10, Jalnidhi, Ushar-3 and Mashina Research-2 were screened to select the As tolerant cultivar. Based on accumulation and growth parameters, the tolerant cultivar (cv. Pant 10) of rice was selected for further experiments. Rice cv. Pant 10 was treated with i) As, ii) As+Fe, iii) As+Se, iv) As+Se+P and v) As+P under hydroponic condition for 8d. The application (μg ml-1) of Fe(100) to As(4) and Se(4)+P(6) to As(4), significantly (89% and 73%, respectively) reduced the uptake of As to the shoot without affecting the growth of seedlings. However, increasing the level of P (3 and 6 μg ml-1) alone in As(III) (4 μg ml-1) treatments significantly increased the As accumulation in the shoot, coincided with the decreased growth of rice seedlings. Treatment of As+Fe showed a non-significant reduction in growth relative to As alone, whereas, the seedlings exhibited the higher MDA and H2O2 level at 100 μg ml-1 concentration of Fe. In comparison to Se and P combinations, the Fe was found to be more efficient to significantly reduce the As accumulation. Among all the antioxidants, the activity of SOD and APX was significantly enhanced with the As+Fe(50) at both 4 and 8 days of treatments against As(4). Overall results demonstrate that the application of Fe was more efficient to reduce the uptake of As than Se and P in the rice seedlings.
