Soil salinity is one of the major abiotic stresses limiting plant growth and resulting in crop yield reductions. The adverse effects of salinity stress on plant growth happens in two phases: the osmotic phase, which occurs immediately after salt stress and results in a rapid inhibition in plant growth; and the ionic phase, which occurs after several days or weeks of salt stress, when ions accumulate to high toxic concentrations in the shoot and affects shoot function. Plants have evolved several mechanisms to deal with salt stress, which can be divided into three mechanisms: osmotic tolerance, ion exclusion and tissue tolerance.
