摘　　要：胞质分裂(cytokinesis)是指在同一细胞中在新形成的两个子核之间形成新的间隔,将母细胞一分为二的过程。胞质分裂存在于任何一种生命形式中,从单细胞的细菌到多细胞的真核生物都能进行胞质分裂。近些年由于细胞学方法的改进和研究材料增多等因素,使得对植物胞质分裂发生机制的研究取得了很大的进展。现对植物中不同类型的胞质分裂在细胞学、分子生物学方面的研究进展作一综述。Cytokinesis partitions the cytoplasm of a dividing cell after the duplicated nuclear genome has been separated into two daughter assemblies, and cytokinesis occurs in all life forms from single-celled bacteria to multicellular eucaryotes. Several lines of research have contributed to the analysis of plant cytokinesis, such as the improved technology in cytology and the increased mutations that interfere with cytokinesis. This review focuses on the recent advances in cytology and genetic studies for different types of cytokinesis in plant, and the problem in plant cytokinesis was summarized and discussed.
