Journal ArticleDOI
Rice metal-nicotianamine transporter, OsYSL2, is required for the long-distance transport of iron and manganese.
Yasuhiro Ishimaru,Hiroshi Masuda,Khurram Bashir,Haruhiko Inoue,Takashi Tsukamoto,Michiko Takahashi,Hiromi Nakanishi,Naohiro Aoki,Tatsuro Hirose,Ryu Ohsugi,Naoko K. Nishizawa +10 more
TL;DR: In this article, a functional iron and manganese-nicotianamine complex transporter that is expressed in phloem cells and developing seeds was isolated, and the altered expression of OsYSL2 changes the localization of Fe.
Journal ArticleDOI
Iron fortification of rice seeds through activation of the nicotianamine synthase gene
Sichul Lee,Un Sil Jeon,Seung Jin Lee,Yoon-Keun Kim,Daniel P. Persson,Søren Husted,Jan K. Schjørring,Yusuke Kakei,Hiroshi Masuda,Naoko K. Nishizawa,Gynheung An +10 more
TL;DR: It is suggested that an increase in bioavailable mineral content in rice grains can be achieved by enhancing NAS expression, which led to increased tolerance to Fe and Zn deficiencies and to excess metal toxicities.
Journal ArticleDOI
Overexpression of the Barley Nicotianamine Synthase Gene HvNAS1 Increases Iron and Zinc Concentrations in Rice Grains
Hiroshi Masuda,Kanako Usuda,Takanori Kobayashi,Yasuhiro Ishimaru,Yusuke Kakei,Michiko Takahashi,Michiko Takahashi,Kyoko Higuchi,Hiromi Nakanishi,Satoshi Mori,Naoko K. Nishizawa +10 more
TL;DR: It is suggested that the overproduction of nicotianamine enhances the translocation of Fe and Zn into rice grains.
Journal ArticleDOI
Iron biofortification in rice by the introduction of multiple genes involved in iron nutrition
Hiroshi Masuda,Yasuhiro Ishimaru,Yasuhiro Ishimaru,May Sann Aung,Takanori Kobayashi,Takanori Kobayashi,Yusuke Kakei,Michiko Takahashi,Kyoko Higuchi,Hiromi Nakanishi,Naoko K. Nishizawa,Naoko K. Nishizawa +11 more
TL;DR: The results demonstrate that introduction of multiple iron homeostasis genes is more effective for iron biofortification than the single introduction of individual genes.
Journal ArticleDOI
Overexpression of the OsZIP4 zinc transporter confers disarrangement of zinc distribution in rice plants
Yasuhiro Ishimaru,Hiroshi Masuda,Motofumi Suzuki,Khurram Bashir,Michiko Takahashi,Hiromi Nakanishi,Satoshi Mori,Naoko K. Nishizawa +7 more
TL;DR: Results indicate that constitutive expression of OsZip4 changes the Zn distribution within rice plants, and that OsZIP4 is a critical Zn transporter that must be strictly regulated.
