Salt tolerance in greenhouse-raised SiMYB19 transgenic rice plants. (A,B) Phenotypes of WT (Ki) and transgenic rice plants under normal and 100 mM NaCl conditions. Bar = 2 cm. (C) After 5 d treatment with 100 mM NaCl, all plants were restored to normal conditions for 7 d. Bar = 2 cm. (D) Survival rates of WT and transgenic rice plants after restoration to normal conditions. (E) Malondialdehyde (MDA) content. (F–K) Plant height, root length, aboveground fresh weight, underground fresh weight, aboveground dry weight, and underground dry weight under normal growth conditions and 100 mM NaCl treatment. Data are means ± SD (n = 4), * p < 0.05, ** p < 0.01, t-test.
