“…Our results are consistent with those of Hernandez et al (1995), who reported an increased level of H 2 O 2 in pea chloroplasts subjected to NaCl stress. However, the extent of the increase in H 2 O 2 in the J. curcas plants in the present study was lower than the one found after short-term (3 d) exposure to 150 mmol L -1 NaCl in rice (Lee et al, 2001). MDA, which is a product of lipid peroxidation in plants that are exposed to adverse environmental conditions, is a reliable indicator of free radical formation in tissues.…”

“…Plants respond to salt through changes in several morphological, physiological, biochemical, and metabolic processes (Lee et al, 2001;Zhu, 2002). Salt stress can also trigger various interacting events, including inhibition of enzymatic activities in metabolic pathways, and decreased carbon-use efficiency and decomposition of proteinaceous and membrane structures (Hasegawa et al, 2000;Flagella et al, 2004;Garg and Singla, 2004).…”

Biodiesel is an alternative to petroleum diesel fuel. It is a renewable, biodegradable, and nontoxic biofuel. Interest in the production of biodiesel from Jatropha curcas L. seeds has increased in recent years, but the ability of J. curcas to grow in salt-prone areas, such as the Caatinga semiarid region, has received considerably meager attention. The aim of this study was to identify the main physiological processes that can elucidate the pattern of responses of J. curcas irrigated with saline water, which commonly occurs in the semiarid Caatinga region. This study measured the activity of the antioxidant enzymes involved in the scavenging of reactive oxygen species, which include catalase (CAT) and ascorbate peroxidase (APX), as well as malondialdehyde (MDA) levels. The levels of chlorophyll (Chl), carotenoids, amino acids, proline, and soluble proteins were also analyzed. The net carbon assimilation rate (P N ), stomata conductance (g s ), and transpiration rate (E) decreased with salt stress. The activities of CAT and APX were decreased, while H 2 O 2 and MDA levels as well as electrolyte leakage were significantly increased in salt-stressed plants compared to the untreated ones. These observations suggest that the ability of J. curcas plants resist to salt stress is associated with the activities of protective enzymes and their defensive functions. However, our results indicate that the reactive oxygen species scavenging system is not sufficient to protect J. curcas leaves against oxidative damage caused by salt stress, and, therefore, it cannot be treated as a salt tolerant plant species.

“…However, it has been showed that the increase of the activity of some antioxidant enzymes is concomitantly with salt sensitivity. For example, in the leaves of the salt-sensitive rice plants, NaCl stress preferentially enhanced the activities of some antioxidant enzymes like SOD and APX (Lee et al, 2001). In addition, it has been reported that the responses of plant antioxidant enzymes to salinity show varying activity patterns according to the species and analyzed tissues (Gossett et al, 1994).…”

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.

“…SOD is a crucial component of antioxidative systems in cell metabolism (Liu et al 2009). In this study, SOD activity in A. cepa exposed to different concentrations of LCT was generally higher than that in the control, suggesting that enhanced SOD activity may indicate oxidative stress, which triggers enhanced activity of antioxidant enzymes (Lee et al 2001). The increased SOD levels lead to the over-production of H 2 O 2 .…”

The Effect of Lambda-Cyhalothrin on Root Tip Cytology, Pigment Contents and Antioxidant Defense System of <i>Allium cepa</i>

SummaryIn this study, toxic effects of the lambda-cyhalothrin (LCT) in Allium cepa L. cells were investigated. Toxic effects were investigated by analyzing the leaf contents and the cytologic and antioxidant parameters. To this aim, different doses of LCT were applied to Allium cepa L. samples. As a result, all doses of LCT treatment significantly decreased the leaf pigments compared to the control. The activity of superoxide dismutase, catalase and MDA level showed a concentration-time dependent decrease after treatment. It was also found that LCT has a mitodepressive action on mitosis and produced clastogenic and aneugenic types of abnormalities in Allium cepa with decreased mitotic index depending on the dose of LCT. The data obtained in this study showed that plant bioassays can be used as an important indicator to detect possible genotoxicity of chemicals.
