ABSTRACT
Alteration in the environmental conditions that produce any change in the redox homeostasis can induce oxidative stress in plants. Oxygen is essential for aerobic life, but accumulation of ROS, such as hydrogen peroxide, superoxide radicals, singlet oxygen, and hydroxyl radicals, during the aerobic metabolism can be dangerous for the cell metabolism (Halliwell, 2006; Kim et al., 2008). The most important ROS produced by the cell metabolism are singlet oxygens, superoxide radicals, hydrogen peroxide, and hydroxyl radicals.
