Variations in Soluble Endosperm Proteins of Corn (Zea mays L.) Inbreds as Detected by Disc Gel Electrophoresis.

The possibility that mutant and normal endosperms of corn (Zea mays L.) differ predictably in the electrophoretic banding patterns of their soluble endosperm proteins was examined by polyacrylamide gel electrophoresis. A band designation system was developed. One band was identified as sucrose synthase, and other bands were characterized according to special chemical or physical properties. Four banding patterns were noted among 15 normal inbreds. Each opaque-2 pattern was different from that of the corresponding normal inbred, but no major single band or pattern change distinguished the opaque-2 inbreds as a group. The floury-2 mutation caused a reduction in the amount of a major protein. Several examples of differential genetic control of relative protein levels are presented.
