Fig. 5From: MfbHLH38, a Myrothamnus flabellifolia bHLH transcription factor, confers tolerance to drought and salinity stresses in ArabidopsisAnalysis of ROS accumulation and activities of key antioxidant enzymes under drought and salt treatments. a and b showed the analysis of H2O2 and O2− accumulation by using histochemical staining with DAB and NBT, respectively. Data are presented as mean and SD values of three independent experiments. Asterisks indicated a significant difference (* P < 0.05, ** P < 0.01, by Independent sample T-test) comparing to WT.Back to article page
