Abstract

We are using vertical polyacrylamide gel electrophoresis (Davis, 1964) and a staining system modified after Beauchamp and Fridovich (1971) to study superoxide dismutase polymorphisms in the subgenus soja. This staining system generates superoxide radical; hence, it is specific for SOD activity. We re-solve up to 9 SOD bands in dry or germinating soybean cotyledons, and in leaves.
