Drought and salt tolerance test in HSFA6b mutants. A, Twenty-four-day-old plate-grown seedlings were photographed (left), then the chlorophyll a/b and chlorophyll/anthocyanin ratios were measured (right). Data are means ± sd of three biological replicates. *Significant at P < 0.05 compared with Col. B and C, Two-week-old seedlings were watered with 300 mm NaCl, then photographed at 2 and 5 weeks after treatment, respectively. The survival rates were analyzed after treatment with water containing 300 mm NaCl for 5 weeks. Arrows show surviving seedlings. One preventative data set is shown. Data are means ± sd of three biological replicates.
