TL;DR: The results indicate that the C. merolae genome provides a model system with a simple gene composition for studying the origin, evolution and fundamental mechanisms of eukaryotic cells.
Journal ArticleDOI
A 100%-complete sequence reveals unusually simple genomic features in the hot-spring red alga Cyanidioschyzon merolae
Hisayoshi Nozaki,Hiroyoshi Takano,Osami Misumi,Kimihiro Terasawa,Motomichi Matsuzaki,Shinichiro Maruyama,Keiji Nishida,Fumi Yagisawa,Yamato Yoshida,Yamato Yoshida,Takayuki Fujiwara,Susumu Takio,Katsunori Tamura,Sung Jin Chung,Soichi Nakamura,Haruko Kuroiwa,Kan Tanaka,Naoki Sato,Tsuneyoshi Kuroiwa +18 more
TL;DR: The C. merolae genome contains the smallest known histone-gene cluster, a unique telomeric repeat for all chromosomal ends, and an extremely low number of transposons, which are extremely useful for further studies of eukaryotic cells.
Journal ArticleDOI
Isolated chloroplast division machinery can actively constrict after stretching.

TL;DR: Dynamin may generate the motive force for contraction by filament sliding in dividing chloroplasts, in addition to pinching-off the membranes in red alga Cyanidioschyzon merolae.
Journal ArticleDOI
Cyanidioschyzon merolae genome. A tool for facilitating comparable studies on organelle biogenesis in photosynthetic eukaryotes.
Osami Misumi,Motomichi Matsuzaki,Hisayoshi Nozaki,Shin-ya Miyagishima,Toshiyuki Mori,Keiji Nishida,Fumi Yagisawa,Yamato Yoshida,Haruko Kuroiwa,Tsuneyoshi Kuroiwa +9 more
TL;DR: The characteristics of double membrane- and single membrane-bound organelles and their related genes in C. merolae and C. reinhardtii are reported and most core biological functions are carried out by orthologous proteins that occur in comparable numbers.
Journal ArticleDOI
Chloroplasts Divide by Contraction of a Bundle of Nanofilaments Consisting of Polyglucan

TL;DR: By proteomic analysis of PD machineries isolated from Cyanidioschyzon merolae, the glycosyltransferase protein plastid-dividing ring 1 (PDR1), which constructs the PD ring and is widely conserved from red alga to land plants is identified.
