Salinity stress is one of the adverse stresses among abiotic stress which mitigates ion toxicity, water unavailability and oxidative stress apart from the hampering growth and productivity of plants. Various anthropogenic activities also indulge in limiting the cultivatable land thus minimizing the food productivity. For sustainable food supply to world population which is increasing at its peril, it is important to develop stress tolerant crops. Salt adaptation involves various trait of gene which comes across in an integrated manner to lessen the adverse effect of salt. This salt signaling cascade activates various mechanisms after perceiving the signal at membrane level receptor which leads to activate the various genes and transcription factors involved in production of osmolytes and ion sequestration. In this review we tried to accentuate the impacts of salinity on plant, role of calcium ion, transcription factor, osmolytes and plant hormone in salt tolerance.
