Protein bodies in embryonic axes of soybean seeds have inclusion structures containing phytin globoids. Biogenesis of the protein bodies during seed development was examined by transmission electron microscopy. Protein bodies in embryonic axes originated from central vacuoles. The central vacuole in embryonic axes subdivided into smaller vacuoles with internal membranous structure. Then the subdivided vacuoles were directly associated with rough endoplasmic reticulum (rER), and were filled with proteinaceous matrix from the peripheral region. The increase of matrix was simultaneous with accumulation of β-conglycinin estimated by SDS-polyacrylamide gel electrophoresis. Glycinin-rich granules that had been found in developing cotyledons were not observed in embryonic axes. After proteinaceous matrix filled the protein bodies, electron-transparent regions presumably surrounded by a single membrane appeared in the matrix. Phytin globoids were constructed in this internal structures of protein bodies as the final step of protein body formation.
