Figure 7. Drought and cold stress tolerance of 25–20 and 27–3.

Figure 7

(A) Typical plants of Toyohikari (wild type) and transgenic lines overexpressing OsABA8ox1 were grown in a greenhouse at 25 °C/20 °C. (B) Drought stress tolerance of Toyohikari (wild type) and transgenic lines overexpressing OsABA8ox1. The weight of harvested leaves was measured at intervals of 15 min, 30 min, or 1 h. Relative fresh weight was calculated to estimate water loss; values are means ± SD of three biological replicates. Significant differences relative to the wild type were determined by Student’s t-tests. *, **, and *** represent P < 0.05, P < 0.01, and P < 0.001 respectively. (C) Typical images of wild-type, 25–20, and 27–3, 2 weeks after cold treatment (4 °C, 5 d). (D) Survival rates of wild-type, 25–20, and 27–3, 2 weeks after cold treatment (4 °C, 5 d). The experiments were repeated four times. Significant differences relative to the wild type were determined by Student’s t-tests. **, P < 0.01.
