The Ca2+-dependent SOS pathway regulating Na+ and K+ homeostasis and long-distance Na+ transport has been reported in Arabidopsis. However, Arabidopsis might not be the best model to analyze the involvement of the SOS pathway in long-distance Na+ trans- port due to the very short stem of these plants which do not allow a precise dissection of the relative content of Na+ in stem versus leaf. This separation would be critical to assess the role of SOS1 in xylem loading/unloading, Na+ export by roots, retention in stems and the differential distribution/accumulation in old leaves. Towards this goal, tomato might represent a superior model due to its anatomical structure and agricultural significance. We recently demonstrated the key role played by the plasma membrane Na+/H+ antiporter SlSOS1 in salt tolerance in tomato by maintaining ion homeostasis under salinity stress and in the partitioning of Na+ in plant organs.This work was supported by grants BIO2006-01955 (A.
