Abstract

The proteins of plant nuclei from Phaseolus vulgaris were separated and analyzed by polyacrylamide gel electrophoresis and amino acid analysis. Comparative studies of some protein fractions revealed quantitative and qualitative differences between the undifferentiated hook and the more differentiated lower hypocotyl of bean. While the histone fractions displayed similar electrophoretic patterns, the acidic protein fractions varied accordingly to the stage of development. Various protein fractions from the same tissue differed markedly in amino acid composition; there was little variation in similar fractions from the two stages of differentiation.
