Studies using light and electron microscopy, and energy-dispersive X-ray analysis have allowed us to identify phytin particles within the cytoplasm of the developing endosperm of castor bean (Ricinus communis L.). These particles are present at the time of the formation of globoid particles within the protein bodies, but they are absent from mature tissue with fully formed protein bodies. We suggest that phytin is formed initially in the cytoplasm (perhaps in association with the cisternal endoplasmic reticulum) before being transported to the protein bodies, wherein it condenses to form the globoid.
利用光学和电子显微镜以及能量色散 X 射线分析，我们能够鉴定出在蓖麻（Ricinus communis L.）胚乳发育过程中的细胞质中的植酸颗粒。这些颗粒在球状颗粒在蛋白体中形成时就存在，但在成熟组织中，当蛋白体完全形成时，它们就不存在了。我们推测，植酸最初是在细胞质中形成的（可能与 cisternal 内质网有关），然后被运输到蛋白体中，在那里它浓缩形成球状结构。
