Crude protein electrophoresis of seeds of ten species of Solanum L

Abstract

Seeds of mature fruits of ten species of Solanum were collected from the gardens near the screen house, Botany Department, Obafemi Awolowo University, Ile Ife, Osun State, Nigeria. Crude seed proteins were extracted from them and characterised using polyacrylamide gel electrophoresis. Inter and intra specific qualitative and quantitative protein bands depicting some degree of relationships among the taxa were observed. The degree of variation in bands as a measure of genetic divergence of Solanum species is discussed. Electrophoretic mobility of seed proteins revealed different combinations of bands at various distances from the anode was taxon specific and could be used in separating Solanum species

Keywords: Solanum species, Polyacrylamide electrophoresis, Taxonomy.
