Chloroplasts are descendants of cyanobacteria and divide by binary fission. Several components of the division apparatus have been identified in the past several years and we are beginning to appreciate the plastid division process at a mechanistic level. In this review, we attempt to summarize the most recent developments in the field and assemble these observations into a working model of plastid division in plants. 
Plastid division
This review considers the nature of the plastid division machinery that enables binary fission of plastids, from a cell biology perspective and considers how the cell might control aspects of plastid

TLDR
This review compiles reports about bacteria and various photosynthetically active eukaryotes that challenge the current view on the structure of chloroplasts and argues in favor of an evolutionary view on bacterial as well as on plastid cell biology.
Coordination of Chloroplast Envelope Division
TLDR
This work has shown that chloroplasts arose from cyanobacteria and divide by binary fission, and their division requires the coordinated action of the inner and outer chloroplast membrane constriction machineries.
Characterization of Thylakoid Division Using Chloroplast Dividing Mutants in Arabidopsis
TLDR
Thylakoids do not divide independently of the chloroplast division cycle, and it is shown that thylakoid division requires the formation of both the inner and the outer contractile rings of thechloroplast.
A role for mechanosensitive channels in chloroplast and bacterial fission
TLDR
The effect of heterologous expression of the Arabidopsis MS channel homolog MSL2 on FtsZ ring placement in E. coli is described and possible molecular mechanisms by which MS channels might influence chloroplast or bacterial division are discussed.
Divide and shape: an endosymbiont in action
TLDR
This article considers how variation in morphology might be controlled and how other types of plastids might divide efficiently, especially the proplastid, the progenitor of all plastid types in the cell.
The Molecular Machinery of Chloroplast Division1[OPEN]
Recent studies advance understanding of the mechanisms, spatial control, and regulation of chloroplast division, but many questions remain.
Distinct functions of chloroplast FtsZ1 and FtsZ2 in Z-ring structure and remodeling
The distinct morphological and dynamic properties of their respective filaments suggest that FtsZ1 facilitates Z-ring remodeling, whereas FtsZ2 forms the Z-ring backbone during chloroplast division.
Chloroplast Biogenesis: Control of Plastid Development, Protein Import, Division and Inheritance
TLDR
Fundamental aspects of plastid gene expression/regulation and chloroplast protein transport are described, together with recent proteome analyses of the organelle.

TLDR
The FtsZ protein, which self-assembles into a membrane-associated ring structure early in the division process, is homologous to tubulin, the building block of the microtubule cytoskeleton in eukaryotes.
Cell and plastid division are coordinated through the prereplication factor AtCDT1.
TLDR
Down-regulation of At CDT1a and AtCDT1b, members of the prereplication complex, is shown to alter both nuclear DNA replication and plastid division in Arabidopsis thaliana, providing molecular evidence for relationships between the cell-cycle and plASTid division.
The Division of Endosymbiotic Organelles
TLDR
This work has shown that mitochondria and chloroplasts universally require dynamin-related guanosine triphosphatases to divide, and provides fundamental insights into the molecular events driving the division, and possibly the evolution, of organelles in eukaryotes.
Plastid division: evolution, mechanism and complexity.
TLDR
The currentUnderstanding of the mechanism of chloroplast division in higher plants is reviewed with an emphasis on how recent findings are beginning to shape the understanding of the function and evolution of the components.
Dual targeting of plastid division protein FtsZ to chloroplasts and the cytoplasm
TLDR
It is demonstrated that a novel FtsZ isoform in the moss Physcomitrella patens is located not only in chloroplasts but also in the cytoplasm, assembling into rings in both cell compartments, indicating that this protein might connect cell and organelle division at least in moss.
Chloroplast Division in Higher Plants Requires Members of Two Functionally Divergent Gene Families with Homology to Bacterial ftsZ
TLDR
The identification of a second nuclear-encoded FtsZ-type protein from Arabidopsis that does not contain a chloroplast targeting sequence or other obvious sorting signals and is not imported into isolated chloroplasts, which strongly suggests that it is localized in the cytosol.
An Arabidopsis Homolog of the Bacterial Cell Division Inhibitor SulA Is Involved in Plastid Division
TLDR
A new component of the plastid division machinery, Arabidopsis thaliana SulA is identified, demonstrating that its role in plastids division may involve an interaction with AtFtsZ1-1 and AtFTSZ2-1.
