Chloroplast division site placement requires dimerization of the ARC11/AtMinD1 protein in Arabidopsis.
Chloroplast division is mediated by the coordinated action of a prokaryote-derived division system(s) and a host eukaryote-derived membrane fission system(s). The evolutionary conserved prokaryote-derived system comprises several nucleus-encoded proteins, two of which are thought to control division site placement at the midpoint of the organelle: a stromal ATPase MinD and a topological specifi...
متن کاملChloroplast Division: A Work of ARTEMIS
Chloroplasts contain three membrane systems that constrict together during division of the organelle. A newly identified protein, ARTEMIS, may shed light on the nuclear control of chloroplast division, and also on the mechanism of thylakoid membrane fission and how this is coordinated with fission of the two envelope membranes.
متن کاملCell and chloroplast division requires ARTEMIS.
Chloroplasts are endosymbiotic organelles of cyanobacterial origin. It seems reasonable to assume that cell division and organelle division still share general principles, as shown for the FtsZ proteins. However, further components involved in this process are largely unknown. Here we describe ARTEMIS, a nuclear-encoded protein of chloroplast inner envelope membranes that is required for organe...
متن کاملInsights into the Mechanisms of Chloroplast Division
The endosymbiosis of a free-living cyanobacterium into an ancestral eukaryote led to the evolution of the chloroplast (plastid) more than one billion years ago. Given their independent origins, plastid proliferation is restricted to the binary fission of pre-existing plastids within a cell. In the last 25 years, the structure of the supramolecular machinery regulating plastid division has been ...
