FIGURE 8.

Changes of ABA content in transgenic plants during stress conditions. Fifteen-day-old seedlings were transferred to 1/2 MS medium supplemented with 50 μM ABA, 200 mM NaCl, or 300 mM mannitol for 0, 1, 6, and 24 h. (A) ABA content of the wild-type and transgenic leaves after ABA treatment for 0, 1, 6, and 24 h; (B) ABA content of the wild-type and transgenic leaves after mannitol treatment for 0, 1, 6, and 24 h; (C) ABA content of the wild-type and transgenic leaves after NaCl treatment for 0, 1, 6, and 24 h. Values are mean ± SD (n = 3). Means denoted by the same letter did not differ significantly at P < 0.05.
