Fig. 7 in NtCOMT1 responsible for phytomelatonin biosynthesis confers drought tolerance in Nicotiana tabacum

Fig. 7. Histochemical staining with DAB for detection of H2O2 (A), the content of H2O2 (B) and MDA (C), and the antioxidant enzyme activities of CAT (D) and SOD (E) in NtCOMT1 overexpressing lines, WT, and OE-Empty tobacco after drought treatment. Data are means ± SE of three biological replicates and means followed by different letters are significantly different (p <0.05).
