Conejero, Department of Plant Pathology and Cell Interaction Group, University of California, Riverside, CA 92521; J. S. Semancik, Department of Plant Pathology and Cell Interaction Group, University of California, Riverside, CA 92521. Phytopathology 67:1424-1426. Accepted for publication 5 April 1977.

A discontinuous system for polyacrylamide-SDS slab gel electrophoresis of plant proteins is described. High resolution of low-molecular-weight protein bands was achieved even when working with protein preparations obtained from highly pigmented, crude plant extracts.
