Protein bodies of pumpkin cotyledon cells were oval (about 10 × 7 μm), and each was composed of a crystalloid, a globoid and proteinaceous matrix. They started to swell and fuse with 1 day of imbibition. The proteinaceous matrix region expanded at the expense of crystalloids, and its electron density decreased. Finally, the protein bodies became central vacuoles including many small protein particles in about 8 days of germination. Fluorescent microscopy using antibodies raised against pumpkin seed globulin showed that fluorescence could not be observed in either protein bodies of ungerminated seeds or crystalloids of germinating cotyledons, and only the proteinaceous matrix of germinating cotyledons became fluorescent. Probable causes of no fluorescence on crystalloids of seed globulin deposition were considered.
