nhx1 nhx2 Mutants Are Not Sensitive to Sodium.
Plants of Col-0 and of nhx1-1 nhx2-1 mutant line L2 (n = 4 per line) were grown for 3 weeks in hydroponic LAK medium with 1 mM KCl and supplemented or not with 50 and 100 mM NaCl. Shown are average and sd values (n = 24)
(A) Fresh weight of shoots and roots of the wild type and mutant line L2.
