A b s t r a c t. Fluctuation of the summer day-time temperatures in the mid-latitudes in a range from 16 to 30 o C should not have irreversible negative effects on plants, but may influence metabolic processes including the oxidative stress. To test the effect of moderately high temperature on oxidative stress induced by lead in the leaves of Plantago major L.; the plants were incubated in a water solution of 0, 150, 450, and 900 µM Pb(NO 3 ) 2 at 20 and 28 o C. Plant reactions were evaluated by the content of thiobarbituric acid reactive substances and ascorbate peroxidase and glutathione reductase activities in leaves after 2, 24, 48, and 72 h. The Pb concentration in the leaves rose with the increase in the Pb content and was higher at 20 o C. The increase in stomatal resistance caused by Pb was higher at 28 o C. The contents of TBARS increased after 2 h of plant exposure to Pb and the increase was the highest at 900 µM Pb, 28 o C. The AsP activity increased up to 50% after 24 h of Pb-treatment at 28 o C; the highest increase in glutathione reductase activity was observed after 72 h at 20 o C. Thus, the moderately high temperature 28 o C compared with optimal 20 o C caused a decrease in Pb accumulation in Plantago leaves but amplified the negative effects of lead, especially in the beginning of stress development.K e y w o r d s: ascorbate peroxidase, glutathione reductase, lead, heat stress, oxidative destruction, Plantago major L.

“…Garlic Allium sativum L. leaves showed an increase in SOD and peroxidase activities at a Pb concentration of 10 -3 M (Liu et al, 2009). In Zea mays seedlings exposed to Pb (0-200 µM), activities of SOD and catalase and the content of ascorbic acid increased linearly with increasing Pb levels (Gupta et al, 2009).…”

“…Similar results were found with S. polyrhiza (Upadhyay and Panda, 2009). Thus, increased MDA indicates the prevalence of oxidative stress and this may be one of the possible mechanisms by which toxicity due to Ni is manifested in plant tissues (Gupta et al, 2009). However, Yamamoto et al (2002) demonstrated that Al cannot catalyse the peroxidation reaction by itself, but enhances the Fe (II or III) mediated non-enzymatic peroxidation of phospholipids.…”

“…In contrast to CAT, APX has a higher affinity for H 2 O 2 , allowing for the scavenging of small amounts of H 2 O 2 in more specific locations (Asada, 1992). In different aquatic and terrestrial plant species, this type of peroxidases (APX) has been shown to be inducible on exposure to different heavy metals (Prasad et al, 1999;Gupta et al, 2009).…”

The process of stress adaption was studied in Groenlandia densa (opposite-leaved pondweed) grown in the presence of different Ni concentrations (0 -20 mg Ni L À 1 ). The results showed that Ni concentrations in plants increased with the increasing Ni supply levels and reached a maximum of 47.57 mg kg À 1 DW at 5 mg L À 1 Ni treatments. The level of photosynthetic pigments (Chl a, Chl b and Chl total) decreased only upon exposure to high Ni concentrations. However, total soluble proteins increased with increasing nickel supply levels. At the same time, the level of malondialdehyde (MDA) increased with increasing Ni concentration. Significant increases in antioxidant activities of studied enzymes such as superoxide dismutase (SOD), catalase (CAT), glutathione reductase (GR), glutathione S-transferase (GST) and ascorbate peroxidase (APX) were recorded in this plant subjected to increasing Ni levels. Cellular antioxidant levels showed a decline suggesting a defensive mechanism to protect against oxidative stress caused by nickel. In addition, the proline content in G. densa increased with increasing nickel levels. These findings suggest that G. densa is equipped with efficient antioxidant mechanism against Ni-induced oxidative stress which protects photosynthetic machinery from damage.Our present study concluded that G. densa has a high level of nickel tolerance and accumulation. We also found that moderate nickel treatment (0.05 -5 mg L ) could cause an increasing generation of ROS, which was effectively scavenged by the antioxidative system. Therefore, G. densa may be used as a phytoremediator in moderately polluted aquatic ecosystems.

“…At 4mg/l arsenic concentration of the protein content was reduced by 48.56% and 68.34% of the control value in Satabdi, and Nayanmani respectively (Fig.10). Protein contents decrease may be due to more oxidative injury by TEs [28,29].…”
