摘　　要：Plastid is one of the most important cellularorganelles, the normal division process of plastid is essential for the differentiation and development of plant cells. For a long time, morphological observations and genetic analyses to special mutants are the major research fields of plastiddivision, but the molecular mechanisms underlying plastiddivision are largely unknown. Because of the endosymbiotic origin, plastid division might have mechanisms in common with those involved in bacterial cell division. It has beenproved that several prokaryotic cell division genes also par-ticipate in the plastid division. Recently, the mechanisms of prokaryotic cell division have been well documented, which provides a valuable paradigm for understanding the plastid division mechanisms. In plants, the functional analyses of ftsZ, a key gene involved both in bacteria and plastid division, have established the solid foundation for people to under-stand the plastid division in molecular level. In this paper we will make a review for the research history and progress of plastid division.Plastid is one of the most important cellular organelles, the normal division process of plastid is essential for the differentiation and development of plant cells.
