Rice is moderately sensitive to salinity,and the response to salt stress is a complex process,including the perception and transduction of salt stress signal,the activation of specific transcriptional factors and the expression of downstream stress-responsive genes.The functions of Na+ transporters which are involved in the maintenance and reconstruction of the ion homeostasis,transcriptional regulators and osmotic regulation genes were reviewed.Salt tolerance of plants are enhanced by Na+ vacuolar compartmentation or efflux or high levels of osmoprotectants accumulation in cytoplasm.
