From: Overexpression of PtrABF gene, a bZIP transcription factor isolated from Poncirus trifoliata, enhances dehydration and drought tolerance in tobacco via scavenging ROS and modulating expression of stress-responsive genes

Figure 9

Activity and expression of antioxidant enzymes (genes) in wild type (WT), transgenic lines (#4 and #19) before and after drought treatment. (A-C) Activity of SOD (A), POD (B) and CAT (C) of WT, #4 and #19 plants before and after 7-d of drought treatment. Enzymes were extracted and assayed as described in 'Materials and methods'. ** indicates that the values of the two transgenic lines are significantly different those of WT (P < 0.01). Expression of the genes encoding the enzymes was examined by RT-PCR and was shown below each graph.
