利用高度同步化的细胞分裂系统研究了长春花细胞周期中高尔基体超微结构的变化。G.唐悬浮培养。在G2期和胞质分裂期，网质体直径和池的数量显著增加。胞质分裂中细胞的电子显微镜照片表明网状体正在分裂为两个。许多分泌囊泡与第二G1期细胞中的网状体相关，此时细胞壁合成最活跃。在高尔基体的结构变化进行了讨论，在细胞周期和细胞壁合成的变化。
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.
