Journal ArticleDOI
The complete nucleotide sequence of the tobacco chloroplast genome: its gene organization and expression.
Kazuo Shinozaki,Masaru Ohme,Minoru Tanaka,Tatsuya Wakasugi,Nobuaki Hayashida,Tohru Matsubayashi,N. Zaita,J. Chunwongse,Junichi Obokata,Kazuko Yamaguchi-Shinozaki,Chikara Ohto,Keita Torazawa,B. Y. Meng,Mamoru Sugita,Hiroshi Deno,T. Kamogashira,Kyoji Yamada,Jun Kusuda,F. Takaiwa,Akira Kato,N. Tohdoh,Hiroaki Shimada,Masahiro Sugiura +22 more
TL;DR: Five sequences coding for proteins homologous to components of the respiratory‐chain NADH dehydrogenase from human mitochondria have been found and sequence and expression analyses indicate both prokaryotic and eukaryotic features of the chloroplast genes.
Journal ArticleDOI
The complete sequence of the rice (Oryza sativa) chloroplast genome: Intermolecular recombination between distinct tRNA genes accounts for a major plastid DNA inversion during the evolution of the cereals
Junzou Hiratsuka,Hiroaki Shimada,Robert F. Whittier,Takashi Ishibashi,Masahiro Sakamoto,Masao Mori,Chihiro Kondo,Yasuko Honji,Chong Rong Sun,Bing Yuan Meng,Yu Qing Li,Akira Kanno,Yoko Nishizawa,Atsushi Hirai,Kazuo Shinozaki,Masahiro Sugiura +15 more
TL;DR: The entire chloroplast genome of the monocot rice (Oryza sativa) has been sequenced and comprises 134525 bp and a model invoking illegitimate recombination between tRNA genes is proposed which accounts simultaneously for the origin of this pseudogene, the large inversion and the creation of repeated sequences near the inversion endpoints.
Journal ArticleDOI
Mobilization of transposons by a mutation abolishing full DNA methylation in Arabidopsis.
Asuka Miura,Shoji Yonebayashi,Koichi Watanabe,Tomoko Toyama,Hiroaki Shimada,Tetsuji Kakutani +5 more
TL;DR: This class of Arabidopsis elements transposes and increases in copy number at high frequencies specifically in the ddm1 hypomethylation background, and the DDM1 gene not only epigenetically ensures proper gene expression, but also stabilizes transposon behaviour, possibly through chromatin remodelling or DNA methylation.
Journal ArticleDOI
The Rc and Rd genes are involved in proanthocyanidin synthesis in rice pericarp.
Tsutomu Furukawa,Masahiko Maekawa,Tomoyuki Oki,Ikuo Suda,Shigeru Iida,Hiroaki Shimada,Itsuro Takamure,Koh Ichi Kadowaki +7 more
TL;DR: In this paper, two genes affecting proanthocyanidin synthesis in red-and brown-colored rice were elucidated, and they were found to encode dihydroflavonol-4-reductase (DFR).
Journal ArticleDOI
Fine structural features of the chloroplast genome: comparison of the sequenced chloroplast genomes
Hiroaki Shimada,Masahiro Sugiura +1 more
TL;DR: The entire nucleotide sequences of the rice, tobacco and liverwort chloroplast genomes have been determined and unidentified ORFs can be assigned to each of these groups such that it is possible to speculate about the functions of products which may be produced by these ORFs.
