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
Deletion in a gene associated with grain size increased yields during rice domestication
Ayahiko Shomura,Takeshi Izawa,Kaworu Ebana,Takeshi Ebitani,Hiromi Kanegae,Saeko Konishi,Masahiro Yano +6 more
TL;DR: Cl cloning of a newly identified QTL, qSW5 (QTL for seed width on chromosome 5), involved in the determination of grain width in rice found that a deletion resulted in a significant increase in sink size owing to an increase in cell number in the outer glume of the rice flower.
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
An SNP caused loss of seed shattering during rice domestication.
Saeko Konishi,Takeshi Izawa,Shaoyang Lin,Kaworu Ebana,Yoshimichi Fukuta,Takuji Sasaki,Masahiro Yano +6 more
TL;DR: Haplotype analysis and association analysis in various rice collections revealed that the SNP was highly associated with shattering among japonica subspecies of rice, implying that it was a target of artificial selection during rice domestication.
Journal ArticleDOI
Characterization of the Silicon Uptake System and Molecular Mapping of the Silicon Transporter Gene in Rice
Jian Feng Ma,Namiki Mitani,Sakiko Nagao,Saeko Konishi,Kazunori Tamai,Takashi Iwashita,Masahiro Yano +6 more
TL;DR: The results indicate that at least two transporters are involved in silicon transport from the external solution to the xylem and that the low-silicon rice mutant is defective in loading silicon into xylesm rather than silicon uptake from external solutions to cortical cells.
