“…These results are in agreement with results obtained by Gang et al [35], who found increase in the total soluble sugars with the increase of Uranium and Thorium concentration in the leaves of Capparis spinosa. Total protein content was found to decline due to uptake of more U and Th in plants from coastal black sand soil.…”

“…Physiological responses of higher plants to environment have been studied extensively over the world. Abiotic environmental stresses are linked with all the living process of higher plants and greatly influence plant growth and productivity [4,35,36]. Although some metals are necessary for biological processes, they are toxic at high concentrations.…”

Current knowledge on the basic radionuclide tolerance indicates that plants may develop mechanisms preventing the damaging effects of radionuclide stress. The radionuclides content was determined in the Mediterranean coastal black sand soil and in the edible portions of the four food crop plant species, viz., Eruca sativa, Lycopersicon esculentum, Pasidium guajava and Mangifera indica. Biochemical and nutritional constituents were assessed to elucidate the possible effect of radionuclides on the edible portions of the plants. The ability of the four study plant species to accumulate Uranium and Thorium in their edible portions from the coastal black sand soil is higher than that absorbed from the inland agricultural soils. The nutritional constituents were affected by the high concentrations of Uranium and Thorium in the plant tissues. The total protein, moisture content, total phenolic compounds, total chlorophyll, total carotenoids, β-Carotene and Lycopene were positively correlated with Uranium and Thorium concentrations in the plant tissues, while the mineral content, vitamin C and total flavonoids were suppressed by high concentrations of Uranium and Thorium in the plant tissues. The fluctuations in the biochemical or nutritional constituents of the plant edible portions are considered an important defense mechanism to control the redox state of the cells accumulating radionuclides with high levels.

“…α-tocopherol, an abundant vitamin E compound, is a lipid soluble antioxidant found in chloroplasts where it counteracts lipid peroxidation through scavenging of lipid peroxyl radicals and detoxifies singlet oxygen and hydroxyl radicals (Munné-Bosch, 2005). Oxidative stress activates the expression of genes responsible for the synthesis of tocopherols in higher plants, generating its accumulation in plants Wu et al, 2007).…”

It has been demonstrated previously that the physiological and molecular analysis of seedlings of the tolerant (Om Rabia3) and susceptible (Mahmoudi) Tunisian wheat genotypes were different at short and long-term response to salinity. In this study, we examined the antioxidant defence system in seedlings of these two cultivars at short-term response to different NaCl concentrations. The findings showed that high salinity tolerance of cv. Om Rabia3, as manifested by lower decrease in its dry biomass, was associated with lower malondialdehyde and hydrogen peroxide contents, lower accumulation of the superoxide (O 2 -) in the roots and the shoots, and also lower decrease in ascorbate content than those in cv. Mahmoudi. Moreover, the expression of some genes coding for antioxidant enzymes such as the catalase, the superoxide dismutase and the peroxidase were enhanced by NaCl stress especially in the salt-tolerant cultivar. In parallel, their activities were increased in response to the same condition of stress and especially in the cv. Om Rabia3. Taken together, these data suggested that the capacity to limit oxidative damage is important for NaCl tolerance of durum wheat.
