nr 1
Lipid peroxidation, which is a natural and essential process, can occur in a non-enzymatic and/or enzymatic way in plant cells. Some of its products have cytotoxic effects on cells, but others function as plant effectors. The lipid peroxidation in plants exposed to heavy metal stress depends on the metal, plant organ, plant species and its genotype.

The activity of lipoxygenase (EC 1.13.11.12) in Arabidopsis thaliana (L.) Heynh seedlings and mature plants was estimated spectrophotometrically at 234 nm. Linoleic acid was used as a substrate. Lipoxygenase activity showed two pH optima: at 7.0 and 10.0 in seedlings, and at pH 8.0 and 10.0 in leaves of mature plants. Seven-week-old plants were transferred to a hydroponic system and treated with different concentrations of Cd2+ or Cu2+ [in μM]: 0, 5, 25, 50, 100 for 7 days. The lipoxygenase activities at pH 8.0 and 10.0 depended on the metal that was added to the nutrient solution. The main change in lipoxygenase activity was under Cd2+ stress at pH 8.0 and under Cu2+ excess at pH 10.0.

Formation of lipid hydroperoxides, malondialdehyde (MDA) and hydroxyalkenals (HAEs), membrane damages and antioxidative response of plants expressed as changes in glutathione S-transferase activity (GST) and anthocyanin accumulation were studied in Arabidopsis thaliana (L.) Heynh cv. Columbia plants treated for 7 days with various concentrations: 5, 25, 50, 100 µM Cd and Cu. Increased lipid hydroperoxide content was metal concentration-dependent. The level of MDA + HAE was elevated in Cd- and Cu- treated plants, but it was metal concentration-dependent under Cu stress. Electrolyte leakage measurements showed a larger membrane damage under Cu- than Cd-treatment. In Cu-stressed plants, GST activity was always enhanced in comparison with control, while in plants exposed to Cd it dropped slightly at lower metal concentrations; but at 100 µM Cd it was even higher than in plants treated with the same Cu concentration. Anthocyanin accumulation was considerably higher under Cu than Cd stress. Both lipid peroxidation and antioxidative response was stronger in Cu- than Cd-treated Arabidopsis thaliana plants. Various mechanisms of defense against the lipid peroxidation products, depending on the metal type, are discussed.

Studies on the possible interference of colchicine and H2O2 with the activity of some antioxidant enzymes were carried out on Arabidopsis thaliana v. Columbia grown in Murashige and Skooge nutrient medium. Measurements of superoxide dismutase (SOD), guaiacol peroxidase (POX), ascorbate peroxidase (APX) and catalase (CAT) activities were conducted spectrophotometrically. In the presence of colchicine, SOD activity increased, while CAT, APX and POX activities decreased. Inhibitory H2O2 effects on the activity of the enzymes were found. Colchicine pre-treatment resulted in an increase in CAT activity and a further increase in SOD activity in plants treated with H2O2.
