Chloroplast Division: A Work of ARTEMIS
نویسنده
چکیده
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.

Cell 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 کاملPhylogeny of Onobrychis sect. Hymenobrychis (Fabaceae) based on chloroplast DNA sequence data
Phenetic analysis of morphological characters in different species of Onobrychis Miller sect. Hymenobrychis DC. (Fabaceae), classified them in two main groups based on corolla features. To determine the phylogenetic relationships among the 13 species, chloroplast DNA sequences were used. Analysis of these data resulted in a well-resolved and well-supported phylogeny. Phylogenies generated by ma...
متن کاملArabidopsis FHY3/CPD45 regulates far-red light signaling and chloroplast division in parallel
CPD45 (chloroplast division45),which is also known as FHY3 (far-red elongated hypocotyl3), is a key factor in the far-red light signaling pathway in Arabidopsis. We previously showed that FHY3/CPD45 also regulates chloroplast division. Because light is also a regulator of chloroplast development and division, we sought to clarify the relationship between far-red light signaling and chloroplast ...
متن کاملDNA REPLICATION AND SYNTHESIS OF DNABINDING PROTEINS IN THE CHLOROPLASTS OF A CALLUS CULTURE
Continuous labelling of callus with H-thymidine results in intermittent peaks of H-DNA per chloroplast, showing synchrony of division. The increase in H-DNA could be due to several replication rounds, and the drop to successive plastid divisions without intervening DNA synthesis. The level of DNA-binding proteins in the chloroplast parallels the peaks of plastidal DNA synthesis; such pro...
متن کاملPlant-Specific Protein MCD1 Determines the Site of Chloroplast Division in Concert with Bacteria-Derived MinD
Chloroplasts evolved from a cyanobacterial endosymbiont, and chloroplast division requires the formation of an FtsZ division ring, which is descended from the cytokinetic machinery of cyanobacteria. As in bacteria, the positioning of the chloroplast FtsZ ring is regulated by the proteins MinD and MinE. However, chloroplast division also involves mechanisms invented by the eukaryotic host cell. ...
