Fig. 6From: Drought-induced ABA, H2O2 and JA positively regulate CmCAD genes and lignin synthesis in melon stemsHistochemical staining (a) and activity detection (b) of GUS driven by promoters with respect to CmCAD1–3 treated with ABA, H2O2 and MeJA. Different lowercase letters indicate significant differences from control using Duncan’s Multiple Range Test (P< 0.05). ND: not detected; ns: no significanceBack to article page
