Adaptation of plants to salt stress requires cellular ion homeostasis involving net intracellular Na(+) and Cl(-) uptake and subsequent vacuolar compartmentalization without toxic ion accumulation in the cytosol. Sodium ions can enter the cell through several low- and high-affinity K(+) carriers. Some members of the HKT family function as sodium transporter and contribute to Na(+) removal from the ascending xylem sap and recirculation from the leaves to the roots via the phloem vasculature. Na… CONTINUE READING
