Changes in the ultrastructure of the Golgi apparatus during the cell cycle were investigated using a highly synchronized cell division system in a Catharanthus roseus (L.) G. Don suspension culture. During the G2 phase and cytokinesis, diameters of the dictyosomes and the number of cisternae significantly increased. Electron micrographs of cells in cytokinesis suggested that dictyosomes were dividing into two. Numerous secretory vesicles were associated with the dictyosomes in cells of the second G1 phase, the time when cell wall synthesis is most active. Structural changes in the Golgi apparatus are discussed in relation to the cell cycle and changes in cell wall synthesis.
利用长春花悬浮培养中的高度同步细胞分裂系统，研究了细胞周期中高尔基体超微结构的变化。在G2期和胞质分裂期间，高尔基体的直径和潴泡数量显著增加。胞质分裂期细胞的电子显微镜照片显示高尔基体正在一分为二。在第二个G1期（细胞壁合成最活跃的时期）的细胞中，大量分泌囊泡与高尔基体相关联。本文讨论了高尔基体的结构变化与细胞周期及细胞壁合成变化的关系。
