TL;DR: The draft genome sequence of the filamentous terrestrial alga Klebsormidium flaccidum is reported to elucidate the early transition step from aquatic algae to land plants and suggests that, during evolution, this alga acquired the fundamental machinery required for adaptation to terrestrial environments.
Journal ArticleDOI
DNA Microarray Analysis of Cyanobacterial Gene Expression during Acclimation to High Light
TL;DR: DNA microarrays bearing nearly all of the genes of the unicellular cyanobacterium Synechocystis sp PCC 6803 were used to examine the temporal program of gene expression during acclimation from low to high light intensity.
Journal ArticleDOI
Complete genome structure of the thermophilic cyanobacterium Thermosynechococcus elongatus BP-1.
Yasukazu Nakamura,Takakazu Kaneko,Shusei Sato,Masahiko Ikeuchi,Hiroshi Katoh,Shigemi Sasamoto,Akiko Watanabe,Mayumi Iriguchi,Kumiko Kawashima,Takaharu Kimura,Yoshie Kishida,Chiaki Kiyokawa,Mitsuyo Kohara,Midori Matsumoto,Ai Matsuno,Naomi Nakazaki,Sayaka Shimpo,Masako Sugimoto,Chie Takeuchi,Manabu Yamada,Satoshi Tabata +20 more
TL;DR: The entire genome of a thermophilic unicellular cyanobacterium, Thermosynechococcus elongatus BP-1, was sequenced, and the presence of 28 copies of group II introns, 8 of which contained a presumptive gene for maturase/reverse transcriptase was observed.
Journal ArticleDOI
Cyanobacteriochromes: a new superfamily of tetrapyrrole-binding photoreceptors in cyanobacteria
Masahiko Ikeuchi,Takami Ishizuka +1 more
TL;DR: A new group of photoreceptors has been experimentally revealed in cyanobacteria and are proposed to be "cyanobacteriochromes", characterized by the presence of a chromophore-binding GAF domain that is homologous to the tetrapyrrole-bindingGAF domain of the phytochrome.
Journal ArticleDOI
A Heterocomplex of Iron Superoxide Dismutases Defends Chloroplast Nucleoids against Oxidative Stress and Is Essential for Chloroplast Development in Arabidopsis
Fumiyoshi Myouga,Chieko Hosoda,Taishi Umezawa,Haruko Iizumi,Takashi Kuromori,Reiko Motohashi,Yuriko Shono,Noriko Nagata,Masahiko Ikeuchi,Kazuo Shinozaki +9 more
TL;DR: It is proposed that heteromeric FSD2 and FSD3 act as ROS scavengers in the maintenance of early chloroplast development by protecting the chloroplower nucleoids from ROS.
