Journal ArticleDOI
Real Time Visualization of 13N-Translocation in Rice under Different Environmental Conditions Using Positron Emitting Tracer Imaging System
Shoichiro Kiyomiya,Hiromi Nakanishi,Hiroshi Uchida,Atsunori Tsuji,Shingo Nishiyama,Masami Futatsubashi,Hideo Tsukada,Noriko S. Ishioka,Satoshi Watanabe,Takehito Ito,Chizuko Mizuniwa,Akihiko Osa,Shinpei Matsuhashi,Shoji Hashimoto,Toshiaki Sekine,Satoshi Mori +15 more
TL;DR: In this article, the authors used positron-emitting 13 N-labeled ammonium (13 NH 4 + ) and 15 O-water to monitor ammonium uptake and nitrogen movement in plants in real time.
Journal ArticleDOI
Quick and reversible inhibition of soybean root nodule growth by nitrate involves a decrease in sucrose supply to nodules.
Hiroyuki Fujikake,Akihiko Yamazaki,Norikuni Ohtake,Kuni Sueyoshi,Shinpei Matsuhashi,Takehito Ito,Chizuko Mizuniwa,Tamikazu Kume,Shoji Hashimoto,N. S. Ishioka,Satoshi Watanabe,Akihiko Osa,Toshiaki Sekine,Hiroshi Uchida,Atsunori Tsuji,Takuji Ohyama +15 more
TL;DR: Results indicate that the decrease in photoassimilate supply to nodules may be involved in the quick and reversible nitrate inhibition of soybean nodule growth.
Journal ArticleDOI
Uptake and transport of positron-emitting tracer (18F) in plants☆
Tamikazu Kume,Shinpei Matsuhashi,Masamitsu Shimazu,Hitoshi Ito,Takashi Fujimura,Katsuhiko Adachi,Hiroshi Uchida,Noriko Shigeta,Hiromitsu Matsuoka,Akihiko Osa,Toshiaki Sekine +10 more
TL;DR: In this article, a positron-emitting tracer imaging system was used to observe the damage and recovery functions of plants in vivo, where the positron emitter was detected with two planar detectors (5 × 6 cm2).
Journal ArticleDOI
Visualizing real time [11C]methionine translocation in Fe-sufficient and Fe-deficient barley using a Positron Emitting Tracer Imaging System (PETIS)
Hiromi Nakanishi,Naimatullah Bughio,Shinpei Matsuhashi,N. S. Ishioka,Hiroshi Uchida,Atsunori Tsuji,Akihiko Osa,Toshiaki Sekine,Tamikazu Kume,Satoshi Mori +9 more
TL;DR: In conclusion, methionine from the above-ground parts of a plant is not a precursor of mugineic acid under Fe-deficiency and the discrimination centre is suggested to play a vital role in the distribution of mineral elements and metabolites in gramin-aceous monocots.
Journal ArticleDOI
Production method of no-carrier-added186Re
Noriko Shigeta,Hiromitsu Matsuoka,Akihiko Osa,Mitsuo Koizumi,Mishiroku Izumo,Katsutoshi Kobayashi,Kazuyuki Hashimoto,Toshiaki Sekine,R. M. Lambrecht +8 more
TL;DR: The theoretical excitation functions for the No-Carrier-added 186W(p,n)186Re reaction were calculated using the ALICE code as discussed by the authors, and the experimental and theoretical results were in good agreement.
