Regulation of antioxidant defense in roots. After treatments for 1 day, the activities of APX (A), SOD (B), CAT (C), and POD (D) were measured. Meanwhile, the transcriptional profiles of APX (E), Mn-SOD and, Cu/Zn-SOD (F), CAT (G), and POD (H) were analyzed. The error bars represent the SD. The different letters indicate significantly different values (P < 0.05 according to Turkey’s multiple range test)
