Halophytes are the native flora of saline soil. They are well adapted to saline soils and get benefit from salt ions. This ability makes them a potential candidates for understanding physiological and biochemical mechanisms of salinity stress tolerance. Oxidative stress signaling and detoxification of reactive oxygen species (ROS) are both important components of salt tolerance mechanisms in these plants. The reactive oxygen species (ROS) play dual role in plant growth, development, and stress tolerance. The ROS are toxic by-products of cellular metabolism, but their key role in stress signaling and development is now emerging. Different biotic and abiotic stress conditions lead to overaccumulation of different kinds of ROS which cause oxidative damage and cell death. However, they also act as signaling molecules in various cellular and developmental processes. The balance, between production and …
