From: GhWRKY15, a member of the WRKY transcription factor family identified from cotton (Gossypium hirsutumL.), is involved in disease resistance and plant development

Figure 7

Expression of GhWRKY15 in tobacco decreased the accumulation of ROS, and MV enhanced GhWRKY15 expression. (A), (B) and (C) show that the expression of GhWRKY15 in tobacco decreased the accumulation of ROS after TMV, CMV or C. gossypii treatment, respectively. The level of H2O2 in the tobacco leaves was determined using 1 mg/ml DAB as substrate. The top figure indicates the visualisation of the H2O2 accumulation, and the bottom figure shows the microscopic observations of the brown precipitate. (D) MV enhances GhWRKY15 expression. Approximately one-week-old cotton seedlings were used for the 0.5 mM MV treatment. Ethidium bromide-stained rRNA was included as a loading control.
