SOD activity and protein decline in GA-treated but not ABA-treated aleurone layers over time. A, SOD activity gel of homogenates of GA- or ABA-treated aleurone layers. B, Immunoblot of homogenates of GA- or ABA-treated aleurone layers probed with an anti-maize cytosolic Cu/ZnSOD PAb. Size of an Mr marker is indicated on the left. The positions of MnSOD and Cu/ZnSOD on the activity gel are indicated.
