Isolated Thellungiella shoots do not require roots to survive NaCl and Na2SO4 salt stresses.

Shoots of Thellungiella derived by micropropagation were used to estimate the plants' salt tolerance and ability to regulate Na+ uptake. Two species with differing salt tolerances were studied: Thellungiella salsuginea (halophilla), which is less tolerant, and Thellungiella botschantzevii, which is more tolerant. Although the shoots of neither ecotype survived at 700 mM NaCl or 200 mM Na2SO4, micropropagated shoots of T.
