The endosymbiotic evolution of the plastid within the host cell required development of a mechanism for efficient division of the plastid. Whilst a model for the mechanism of chloroplast division has been constructed, little is known of how other types of plastids divide, especially the proplastid, the progenitor of all plastid types in the cell. It has become clear that plastid shape is highly heterogeneous and dynamic, especially stromules. This article considers how such variation in morphology might be controlled and how such plastids might divide efficiently.
质体在宿主细胞内的内共生进化需要发展一种有效的质体分裂机制。虽然已经构建了叶绿体分裂机制的模型，但对于其他类型的质体如何分裂，特别是原质体（细胞中所有质体类型的前体）的分裂机制，知之甚少。已经很清楚的是，质体的形状是高度异质和动态的，特别是类基质体。本文考虑了这种形态变化是如何被控制的，以及这种质体如何有效地分裂。
