Salt stress affects seed germination, root elongation, and leaf area in strp and STRP OE plants. (A) Germination rate was determined on 200 A. thaliana wt, strp, and STRP OE seeds sowed on Murashige and Skoog (MS) supplemented with 50, 100, and 150 mM NaCl. The seeds’ germination rate was assessed after one week. (B) for leaf area measurement and (C) primary root elongation, wt, strp, and STRP OE plants were grown for four days on MS medium and then transferred on the same medium supplemented with 50, 100, and 150 mM NaCl. After one-week, leaf area and primary root elongation were measured by analyzing digital pictures with the Easy Leaf Area and ImageJ software, respectively. Error bars are s.e.m. of three independent experiments. * p < 0.05, ** p < 0.01, *** p < 0.001, **** p < 0.0001, by Student’s t-test.
