Reactive oxygen species (ROS) are byproducts of normal plant metabolism and their production is elevated under environmental stresses such as drought, extreme temperature, salinity. Among these, salinity a worldwide problem that impacts the fertility arable lands sustainability food security, which getting more attention due to climate change. Halophytes can survive reproduce in soils containing high concentrations salt have developed adaptation mechanisms at physiological, biochemical, molecular levels including maintenance ROS metabolism. In this review, we aim summarize findings related production, signaling, scavenging, especially avoidance stress. addition, expressions antioxidant genes Arabidopsis thaliana its close relative, model halophyte Schrenkiella parvula, compared. Moreover, time-course expression encoding major enzymes A. analyzed with publicly available data understand rapid responses defense The role ROS-Ca+2 interaction involvement NADPH oxidases process also discussed context perception signaling
