Accumulation of reactive oxygen species (ROS) in SKS13 overexpressing plants. 3-3’-diaminobenzidine (DAB) staining of detached leaves from Ws, mutant 3790, Col-0 and SKS13 overexpressing transgenic line G101. The arrows indicate the part of each leaf that was injured by forceps to serve as a positive control for the DAB staining.
