Fig. 5. Changes in (A) SOD, (B) CAT, (C) APX, and (D) GR isozyme profiles in cold-acclimated (lower panel) and nonacclimated rice leaves (upper panel) during acclimation (1–3 d), chilling (4–6 d), and recovery (7–11 d). The plants were exposed to 15°C (cold-acclimated) or 25°C (nonacclimated) for 3 d (acclimation), chilled for 3 d at 5°C (chilling), and allowed to recover for 5 d at 25°C (recovery).
