The wound response of rice roots is not altered by flooding. Wound induction patterns of JA (A), JA-Ile (B), ABA (C), and SA (D) in rice roots growing in flooded and nonflooded substrate are shown 1 and 4 h postinduction (n = 5; + se). The results of two-way ANOVAs are indicated. Different letters indicate significant differences among treatments within time points (P < 0.05). FW, Fresh weight; FxW, flooding × wounding. *, P < 0.05; **, P < 0.01; ***, P < 0.001.
