Functional complementation of Arabidopsis mutant sos1-1 by four SOS1s. (a) Germination of sos1-1 and eight transgenic Arabidopsis mutant sos1-1 lines (sM-1, sM-2, sF-1, sF-2, sD-1, sD-2, sS-1 and sS-2) after 7 days sown on 1/2 MS and 1/2 MS with 75 mM NaCl. (b) Mutant sos1-1 and four SOS1s transgenic seedlings grown on 1/2 MS medium for six days and then transferred to 1/2 MS medium containing 75 mM NaCl and imaged after 7 days of salt treatment and the root elongation (c) and fresh weight of each of above mentioned lines were measured. Error bars represent SD (n = 15). (TIF 1979 kb
