Plants confront an extent of abiotic stresses due to environmental hardship, among which salinity is one of the major abiotic stresses that seizes plant growth and development resulting in a massive yield loss worldwide. Plants respond to salinity in two distinct phases: a quick osmotic phase and a sluggish ionic phase also known as hyper osmotic phase. Plants adjustment and/or tolerance to salinity stress comprise several complex physiological, biochemical and molecular networks. A widespread understanding of how plants response to salinity stress at different phases, and a cohesive physiological and biochemical approaches are crucial for the development of salt adapted and/or tolerant varieties for salt-affected areas. Researchers have identified several adaptive responses to salinity stress at cellular, biochemical and physiological levels, even though mechanisms triggering salt stress adaptation and/or tolerance are far from being entirely understood. This article bestows a spacious review of foremost research advances on physiological and biochemical mechanisms governing plant adaptation and/or tolerance to salinity stress relevant to environmental sustainability and as well as food production.
