“…The enzyme guaiacol peroxidase was significantly increased by 2,4‐D treatment, mainly in young shoots. Similar results were obtained in wheat leaves (Michałowicz et al . 2009) and potato cell culture (Peixoto et al .…”

“…Analysis of oxidative markers in both parts of the plant showed an increase of oxidative damage to proteins and lipids induced by treatment with 2,4‐D, mainly in young leaves, probably as result of a higher accumulation of the herbicide in this part of the plant, and oxidative reactions could be involved in the disturbances of cell structure produced by the herbicide. An increase of lipid peroxidation by 2,4‐D has also been reported in microsomes from pea leaves (Pogosyan, Shevchenko & Merzlyak 1984) and in wheat plants 2,4‐D and other chlorophenols produced lipid peroxidation (Michałowicz, Posmykb & Dudaa 2009).…”

In this work the differential response of adult and young leaves from pea (Pisum sativum L.) plants to the herbicide 2,4-dichlorophenoxyacetic acid (2,4-D) (23 mm) applied by foliar spraying was investigated. The concentration of 2,4-D (23 mm) and the time of treatment (72 h) were previously optimized in order to visualize its toxic effects on pea plants. Under these conditions, the herbicide induced severe disturbances in mesophyll cells structure and proliferation of vascular tissue in young leaves and increased acyl-CoA oxidase (ACX), xanthine oxidase (XOD) and lipoxygenase (LOX) activities in young leaves, and only ACX and LOX in adult leaves. This situation produced reactive oxygen species (ROS) over-accumulation favoured by the absence of significant changes in the enzymatic antioxidants, giving rise to oxidative damages to proteins and membrane lipids. An increase of ethylene took place in both young and adult leaves and the induction of genes encoding the stress proteins, PRP4A and HSP 71,2, was observed mainly in young leaves. These results suggest that ROS overproduction is a key factor in the effect of high concentrations of 2,4-D, and ROS can trigger a differential response in young and adult leaves, either epinasty development in young leaves or senescence processes in adult tissues.

“…Our results showed a high increase of CAT activity in treated seedling and plants of tomato, may be due to H 2 O 2 accumulation, because catalase is one of the major antioxidant enzymes responsible for its elimination (Song et al 2006). Literature reported that in consequence to exposition to xenobiotics, catalase was generally stimulated to eliminate the H 2 O 2 generated, as underlined for example in T. aestivum, which displayed an important increase in CAT activity after exposure to pentachlorophenol et 2,4-dichlorophenol (Michałowicz et al 2009). The electrophoretic study of catalase activity revealed the apparition of a new isoenzyme in treated seedlings of tomato when applying a higher concentration of insecticides and two new isoenzymes in treated leaves; whereas, in roots, there is no qualitative difference between treated samples and control.…”

Tomato (Lycopersicon esculentum Mill.) becomes one of the world's foremost vegetables, and its world production and consumption have increased fairly quickly. The capacity to induce oxidative stress in tomato plant, exposed to three xenobiotics such as alpha-cypermethrin, chlorpyriphos, and pirimicarb, was investigated by the evaluation of lipid peroxidation by measuring malondialdehyde (MDA) rate; also, we studied the response of tomato to this stress by assessing the response of superoxide dismutase (SOD), catalase (CAT), peroxidase (POD), ascorbate peroxidase (APX), glutathione-s-transferase (GST), and glutathione reductase (GR). The effect of the insecticides was observed using four concentrations (25, 50, 75, and 100%) for germinating seeds and only the recommended concentration in agriculture (100%) for growing plants. Our results show an important accumulation of MDA, demonstrating the increase of lipid peroxidation in consequence of the excessive reactive oxygen species (ROS) production due to insecticide treatment. In response to this oxidative stress in tomato seedlings and plants, the activities of antioxidant-enzyme system were generally enhanced. The electrophoretic analysis showed also the apparition of new isoenzymes as the case for CAT and POD.

“…Changes in enzymatic and non-enzymatic antioxidants and lipid peroxidation (TBARS content) in the leaves of reed canary grass (Phalaris arudinacea) exposed to 0.5 mg kg -1 (soil) of 2,4-DCP and PCP for 3, 6 and 12 d. Means of five to six separate experiments ± SE; **, * -the values statistically different from control at P < 0.01 and P < 0.05, respectively, according to t-test. observed in the leaves of wheat exposed to chlorophenols (Michałowicz et al 2009), however, this process was not decreased with time of the exposure of plants to these compounds. This finding may suggest that wild plants are more resistant to lipids damage provoked by chlorinated compounds including chlorophenols in comparison to cultivated plants.…”

The purpose of this work was to evaluate the effect of 2,4-dichlorophenol (2,4-DCP) and pentachlorophenol (PCP) on the activity of antioxidative system and lipid peroxidation in the leaves of reed canary grass (Phalaris arudinacea). The activity of catalase (CAT), ascorbate peroxidase (APX), guaiacol peroxidase (GPX), glutathione reductase (GR) and glutathione S-transferase (GST) as well as the content of glutathione, ascorbate and phenolic compounds were determined. An induced-increase in the APX, CAT, GPX and GR activities was stronger for PCP, while a significant increase in the GST activity was noted only for 2,4-DCP. Both compounds increased the content of phenolic compounds, oxidized and reduced glutathione as well as the content of ascorbic acid. PCP induced stronger increase in lipid peroxidation than 2,4-DCP. The observed changes revealed that chlorophenols induce oxidative stress and oxidative damage in the leaves of reed canary grass.
