摘要：
Recent progress has been made in the characterization of cation transporters that maintain ion homeostasis during salt stress in plants. Sodium-proton antiporters at the vacuolar (NHX1) and plasma membrane (SOS1) have been identified in Arabidopsis. SOS1 is regulated by the calcium-activated protein kinase complex SOS2-SOS3, In yeast, a transcription repressor, Sko1, mediates regulation of the sodium-pump ENA1 gene by the Hog1 MAP kinase. The recent visualization at the atomic level of the inhibitory site of sodium in the known target Hal2 has helped identify the interactions determining Na+ toxicity.
