Merr.), cotyledons contained plastids and lipid bodies at the earliest stage investigated, 15 days after flowering. Lipid bodies seemed to arise directly in the cytoplasm and their proximity to plastids maybe coincidental. By 34 days after flowering lipid bodies increased dramatically accompanied by a massive proliferation of rough endoplasmic reticulum. In some instances this rough endoplasmic reticulum was closely associated with lipid bodies but in other cases there was no close association. In maturing seeds, plastids were frequently seen to contain lipid bodies which may indicate a loss of plastid integrity. Mature seeds contained numerous discrete lipid bodies which stained uniformly and had a half‐unit membrane border. A possible route for lipid body ontogeny consistent with the ultrastructural observation is that fatty acids are just synthesized in the plastids. Possibly then the fatty acids are transported and assembled into triglyceride molecules by the rough endoplasmic reticulum and released into the cytoplasm. Also the proteinaceous material associated with the lipid body membrane probably originate from the endoplasmic reticulum.Read More
