摘要：

Maize superoxide dismutase (superoxide: superoxide oxidoreductase, EC 1.15.1.1; abbreviated as SOD) has been resolved into five major electrophoretic forms by starch gel electrophoresis. All five isozymes are present in the tissues examined. Superoxide dismutase, catalase, and peroxidase activity was measured in the scutellum during kernel development and germination with no obvious correlations being observed. Superoxide dismutase activity is associated with the cytosolic, mitochondrial, and chloroplastic fractions of maize seedlings. Cyanide-sensitive SOD-1 is associated with chloroplasts while cyanide-resistant SOD-3 is associated with mitochondria. © 1979, International Society of Differentiation. All rights reserved.
