As a model organism, the Arabidopsis thaliana response to salinity is studied to aid understanding of other more economically important crops.
[2] It has been found in many studies that Arabidopsis thaliana showed enhanced Na+ and H+ extrusion from their cells after exposure to high salinity.
[3] Part of Arabidopsis’ range might have included high salinity soil and the plant started adapting to that.
Upon high salt exposure, Arabidopsis experiences a negative osmotic pressure gradient between the salty solution and its xylem,[4] and it absorbs Na+ through Na+ permeable transporters.
One of the experiments providing the previous pathway utilized Arabidopsis seedlings grown inside X-gal dishes.
