Composition and Structure of Protein Bodies and Spherosomes Isolated from Ungerminated Seeds of Sorghum bicolor (Linn.) Moench.

Abstract

Protein bodies and spherosomes have been isolated from mature seeds of Sorghum bicolor (Linn.) Moench by a procedure which successfully disrupts the protein starch complex in the grain. Protein bodies from whole grain are 68% protein and have a distinct border and a monolithic appearance. Those from embryo are 95% protein and have diffuse borders, vacuoles, and appear very granular. Aleurone tissue protein bodies are 46% protein with a structure similar to those from embryo, but possibly are composed of a protein carbohydrate mixture. Spherosomes from all sources are quite similar in composition and structure. They have an average composition of 27% protein, 12% phosphorus, and 8.6% metals. Microscopically, they appear as small vesicles bounded by a wall which is probably composed of protein and the potassiummagnesium salt of phytic acid.
