Multiple compartmentalization of sodium conferred salt tolerance in Salicornia europaea

► Effects of NaCl on plant growth, Na+ accumulation and distribution were studied. ► Moderate salinity can stimulate Salicornia europaea L. growth. ► Sodium was accumulated predominantly in shoot endodermis tissues. ► Sodium was well compartmentalized into cell vacuoles. ► Genes involved in sodium segregation were upregulated under NaCl treatment.
