Growth status of the whole mature plants of different genotypes under salt stress. Growth of wild-type Col, soar1-2 and soar1-3 mutants, abi1-3 abi2-2 double knockout-mutant, the ABI2-overexpression line ABI2-OE, and SOAR1-overexpression lines OE1 and OE6 is shown after NaCl treatment. Ten-day-old seedlings were transferred to soil and continued to grow 1 week before the NaCl treatment. NaCl solution was imposed with three increasing concentrations (100, 150, and 200). With each NaCl concentration the plants were irrigated one time at an interval of 4 days, and for a total period of 12 days plants were irrigated three times with corresponding concentrations of NaCl, and then they continued to be irrigated with 200 mM NaCl solution two times at an interval of 4 days, and the pictures were taken 7 days after the last NaCl irrigation. The control plants were irrigated with water. The entire experiment was replicated three times with similar results
