Plastids are derived from free-living cyanobacteria that were engulfed by eukaryotic host cells through the process of endosymbiosis and, like their cyanobacterial ancestors, divide by binary fission. Over the last decade the continued identification and functional analysis of plastid division components, coupled with ever-increasing genomic resources, have yielded insights into the origins and evolution of the plastid division mechanism in higher plants. Here we review the current understanding of the evolution of the chloroplast division proteins and present a model of how the machinery has developed to execute plastid division in Arabidopsis.
质体起源于自由生活的蓝细菌，这些蓝细菌通过内共生过程被真核宿主细胞吞噬，并且像它们的蓝细菌祖先一样，通过二分裂进行分裂。在过去十年中，对质体分裂成分的持续鉴定和功能分析，以及不断增加的基因组资源，使我们对高等植物质体分裂机制的起源和进化有了深入了解。在这里，我们综述了目前对叶绿体分裂蛋白进化的理解，并提出了一个关于该机制如何在拟南芥中发展以执行质体分裂的模型。
