Plastid division mechanisms and their diversity

Bova D.O., Kostikov I.Yu.
Abstract

Review deals with the analysis of literature data about molecular mechanisms and apparatuses of plastid division in photoautotrophic organisms of different phyla. Division apparatuses of eubacteria (including cyanobacteria), primary and secondary plastids of algae and land plants as well as of apicomplexans are discussed. Three types of plastid division defined as prokaryotic (Glaucocystophyta), mixed prokaryotic-eukaryotic (all other algae and land plants) and eukaryotic (Apicomplexa) are reviewed. The principles of positioning, assembly, structure and functioning of the divisome and PDF (Plastid-dividing, Dynamin, and FtsZ rings) system are discussed. We reviewed localizations, functions and interactions of proteins involved in the division of bacteria and the different types of plastids. Furthermore, we discussed the evolutionary origin of the different components of plastid division apparatuses.
