AB control of redox homeostasis in roots. After treatments for 3 days, the contents of H2O2 and O2..− were spectrophotometrically analyzed (A, B) and histochemically stained (C). Meanwhile, the contents of TBARS (D) and REC (E) were also measured. The error bars represent the SD. The different letters indicate significantly different values (P < 0.05 according to Turkey’s multiple range test)
