Inorganic nitrogen is a key element for plant growth under salt stress.
A comparative study including phys-iological responses, ion content, transcript regulation of ammonium/nitrate transporters (AMTs/NRTs) aswell as key enzymes for nitrogen assimilation was undertaken in wild salt-tolerant tomatoes (Solanumpennellii) and cultivated tomatoes (Solanum lycopersicon) exposed to 100 mM NaCl for 1 and 7 days.
