Formation, cellular distribution and structural changes of storage lipid, and active site and cellular localization of lipase in endosperms and cotyledons of lipid-rich seeds such as Helianthus annuus, Ricinus communis and Pinus koraiensis, and in those of starch-rich seeds such as Pisum sativum and Zea mays were investigated in relation to the seed development by cytochemical methods. In endosperms and storage cotyledons of lipid- and starch-rich seeds after seed-gathering, there were widely distributed storage material which was composed of spherical protein bodies, spherosomes, and starch granules. But cellular organelles were hardly observed in the cytoplasm. Staining pattern of vesicles released from SER, and of low electron dense membraneous granules, which were perhaps at an early stage of spherosomes, were the same as in the spherosome. Electrondense granules released from RER were observed in the vicinity of plasma membrane. As a result of lipid staining, the spherosomes were more electron dense and were uniform as compared with the protein matrix within the protein body and cytoplasmic proteinaceous granules. The major component of the spherosome was determinated to be lipid. Spherosomes and vesicles containing SER-released materials showed the same as in the electron density. Lipase activity was especially strong in the inner region and on the surface of decomposed spherosomes and near the plasma membrane.mbrane.
