Journal ArticleDOI
A silicon transporter in rice
Jian Feng Ma,Kazunori Tamai,Naoki Yamaji,Namiki Mitani,Saeko Konishi,Maki Katsuhara,Masaji Ishiguro,Yoshiko Murata,Masahiro Yano +8 more
TL;DR: The identification of a silicon transporter provides both an insight into the silicon uptake system in plants, and a new strategy for producing crops with high resistance to multiple stresses by genetic modification of the root's silicon uptake capacity.
Journal ArticleDOI
Transporters of arsenite in rice and their role in arsenic accumulation in rice grain
Jian Feng Ma,Naoki Yamaji,Namiki Mitani,Xiao-Yan Xu,Yu-Hong Su,Steve P. McGrath,Fang-Jie Zhao +6 more
TL;DR: It is reported that two different types of transporters mediate transport of arsenite, the predominant form of arsenic in paddy soil, from the external medium to the xylem, which explains why rice is efficient in arsenic accumulation.
Journal ArticleDOI
An efflux transporter of silicon in rice
Jian Feng Ma,Naoki Yamaji,Namiki Mitani,Kazunori Tamai,Saeko Konishi,Toru Fujiwara,Maki Katsuhara,Masahiro Yano +7 more
TL;DR: A previously uncharacterized gene is described, low silicon rice 2 (Lsi2), which has no similarity to Lsi1 and is constitutively expressed in the roots and revealed a unique mechanism of nutrient transport in plants: having an influx transporter on one side and an efflux transporter on the other side of the cell to permit the effective transcellular transport of the nutrients.
Journal ArticleDOI
Uptake system of silicon in different plant species.
Namiki Mitani,Jian Feng Ma +1 more
TL;DR: Results suggest that both transporter-mediated transport and passive diffusion of Si are involved in the radial transport of Si and that the transporter- mediated transport is an energy-dependent process.
Journal ArticleDOI
An Aluminum-Activated Citrate Transporter in Barley
Jun Furukawa,Naoki Yamaji,Hua Wang,Namiki Mitani,Yoshiko Murata,Kazuhiro Sato,Maki Katsuhara,Kazuyoshi Takeda,Jian Feng Ma +8 more
TL;DR: It is demonstrated that HvAACT1 is an Al-activated citrate transporter responsible for Al resistance in barley.
