植物的胞质分裂与动物和真菌的胞质分裂有着根本的不同。在植物细胞中，细胞板通过细胞动力小泡的融合形成，然后发育成新的细胞壁，分隔分裂细胞的细胞质。细胞板的形成需要涉及高度协调的囊泡积累、融合和膜成熟的多个阶段，这些阶段与多糖如胼胝质、纤维素和交联聚糖的及时沉积同时发生。本文综述了胞质分裂的主要阶段、参与细胞板组装的内膜成分及其向新细胞壁的转变。一个可以广泛用于教育目的的动画进一步总结了这个过程。
Cytokinesis in plants is fundamentally different from that in animals and fungi. In plant cells, a cell plate forms through the fusion of cytokinetic vesicles and then develops into the new cell wall, partitioning the cytoplasm of the dividing cell. The formation of the cell plate entails multiple stages that involve highly orchestrated vesicle accumulation, fusion and membrane maturation, which occur concurrently with the timely deposition of polysaccharides such as callose, cellulose and cross‐linking glycans. This review summarizes the major stages in cytokinesis, endomembrane components involved in cell plate assembly and its transition to a new cell wall. An animation that can be widely used for educational purposes further summarizes the process.
