Salinity is a major abiotic stress limiting growth and productivity of plants in many areas of the world due to increasing use of poor quality of water for irrigation and soil salinization. Plant adaptation or tolerance to salinity stress involves complex physiological traits, metabolic pathways, and molecular or gene networks. A comprehensive understanding on how plants respond to salinity stress at different levels and an integrated approach of combining molecular tools with physiological and biochemical techniques are imperative for the development of salt-tolerant varieties of plants in salt-affected areas. Recent research has identified various adaptive responses to salinity stress at molecular, cellular, metabolic, and physiological levels, although mechanisms underlying salinity tolerance are far from being completely understood. This paper provides a comprehensive review of major research advances on biochemical, physiological, and molecular mechanisms regulating plant adaptation and tolerance to salinity stress.

- Antioxidants and Antioxidant Enzymes in Higher Plants (2018, background): “…salinity stress, an increase in ROS production (e.g., 1O2, O 2 , ∙OH and H2O2) are observed and these ultimately cause oxidative damage to various cellular components (proteins, lipids and DNA), which in turn can disrupt important plant functions related to its survival (Gupta and Huang 2014).”
