Success story for crop's salinity tolerance: unraveling the molecular mechanisms

High soil salinity results in crop decline and constitutes a major constraint for agriculture, particularly affecting arid and semi-arid areas (James et al., 2012). Irrigation, when not well practiced leaves soils with high salinity. In addition, intrusion of seawater into coastal fresh water reservoirs, and erratic weather patterns, which seem to increase and which add drought years, compound the effects of increasing soil salinity. The problem of plants cultivated in soils with high salinity is the concentration of toxic ions in the root zone, which affects water uptake and transpiration causing ionic and electric imbalances, less growth, delayed development, and may lead to senescence and plant death. The abundance of sodium ions is the most deleterious as it is toxic in the cytosol and competes with potassium ions which are essential for plant’s functioning and are compatible with protein structure, even at high concentration.
