Interspecific diversity in root antioxidative enzyme activities reflect root turnover strategies and preferred habitats in wetland graminoids

Abstract: Antioxidant enzymes protect cells against oxidative stress and are associated with stress tolerance and longevity. In animals, variation in their activities has been shown to relate to species ecology, but in plants, comparative studies with wild species are rare. We investigated activities of five antioxidant enzymes – ascorbate peroxidase (APX), catalase (CAT), glutathione reductase (GR), peroxidase (POX), and superoxide dismutase (SOD) – in roots of four perennial graminoid wetland species over a growing se… Show more

“… 34 In the available literature there are data confirming the importance of antioxidant enzymes in active plant defense mechanisms against abiotic stress factors, such as salinity, toxic metals, cold, drought or deficiency of some macro- and micronutrients, that may increase the ROS level in cells. 35 There are studies that reveal increased activity of antioxidant enzymes in plants under environmental stress which indicates their crucial role in maintaining the appropriate level of ROS inside plant cells. 36 Positive changes in activity of antioxidant enzymes after application of iodine compounds were found by many researchers.…”
