Consequences of oxidative stress on different cellular mechanisms. The imbalance between ROS production and scavenging creates oxidative stress in plants under abiotic stresses. As a consequence, different molecular and cellular damages occur that ultimately cause cell death. ROS—reactive oxygen species; AOX—antioxidants; H2O2—hydrogen peroxide; •OH—hydroxyl radical; O2•−—superoxide anion; 1O2—singlet oxygen.
