OsHMA3, a P1B‐type of ATPase affects root‐to‐shoot cadmium translocation in rice by mediating efflux into vacuoles
Hidenori Miyadate,Saki Adachi,Aya Hiraizumi,Kouichi Tezuka,Nobushige Nakazawa,Tomohiko Kawamoto,Kazunao Katou,Ikuko Kodama,Kenji Sakurai,Hidekazu Takahashi,Namiko Satoh-Nagasawa,Akio Watanabe,Tatsuhito Fujimura,Hiromori Akagi +13 more
TL;DR: It is proposed that the root cell cytoplasm of Cd-overaccumulating rice plants has more Cd available for loading into the xylem as a result of the lack of OsHMA3-mediated transportation of CD to the vacuoles, which results in Cd translocation to the shoots in higher concentrations.
Journal ArticleDOI
Mutations in Rice (Oryza sativa) Heavy Metal ATPase 2 (OsHMA2) Restrict the Translocation of Zinc and Cadmium
Namiko Satoh-Nagasawa,Mikako Mori,Nobushige Nakazawa,Tomohiko Kawamoto,Yasuo Nagato,Kenji Sakurai,Hidekazu Takahashi,Akio Watanabe,Hiromori Akagi +8 more
TL;DR: The C-terminal region of OsHMA2 is identified as essential for Cd translocation into shoots and two alleles were identified as good material for breeding rice that does not contain Cd in the grain but does contain some Zn, and that grows normally.
Journal ArticleDOI
A single recessive gene controls cadmium translocation in the cadmium hyperaccumulating rice cultivar Cho-Ko-Koku.

TL;DR: The data indicate that Cd translocation mediated by the gene on qCdT7 plays an important role in Cd accumulation on contaminated soil.
Journal ArticleDOI
Identification of QTLs controlling low-temperature germination of the East European rice ( Oryza sativa L.) variety Maratteli
Tomohiro Satoh,Kouichi Tezuka,Tomohiko Kawamoto,Shinichi Matsumoto,Namiko Satoh-Nagasawa,Kenji Ueda,Kenji Sakurai,Akio Watanabe,Hidekazu Takahashi,Hiromori Akagi +9 more
TL;DR: It is concluded that the low temperature germinability of various Japanese varieties inferior in this character can be improved by marker-assisted selection without modification of other superior traits.
Journal ArticleDOI
Functional relationship heavy metal P-type ATPases (OsHMA 2 and OsHMA3) of rice ( Oryza sativa ) using RNAi
Namiko Satoh-Nagasawa,Mikako Mori,Kenji Sakurai,Hidekazu Takahashi,Akio Watanabe,Hiromori Akagi +5 more
TL;DR: It is concluded that a complete loss of function of OsHMA2 is crucial to minimize Cd translocation from the roots to the shoots and implied that the activity of OshMA2 can be accelerated in plant in the roots without the C-terminal region of the protein.
