Journal ArticleDOI
High temperature effects on photosynthate partitioning and sugar metabolism during ear expansion in maize (Zea mays L.) genotypes
Ryuichi Suwa,Hiroaki Hakata,Hiromichi Hara,Hany A. El-Shemy,Joseph J. Adu-Gyamfi,Nguyen Tran Nguyen,Synsuke Kanai,David A. Lightfoot,Pravat K. Mohapatra,Kounosuke Fujita +9 more
TL;DR: Plant biomass production was enhanced and grain yield reduced by the high temperature treatment due to effects on sink activity rather than source activity, and heat resistant ear development can be targeted for genetic improvement.
Journal ArticleDOI
The effect of phosphorus deficiency on nutrient uptake, nitrogen fixation and photosynthetic rate in mashbean, mungbean and soybean
Muhammad Iqbal Chaudhary,Joseph J. Adu-Gyamfi,Hirofumi Saneoka,Nguyen Tran Nguyen,Ryuichi Suwa,Shynsuke Kanai,Hany A. El-Shemy,Hany A. El-Shemy,Hany A. El-Shemy,David A. Lightfoot,Kounosuke Fujita +10 more
TL;DR: The results indicate that selection for increased efficiency of P utilization and leaf area may be used to improve leguminous crops.
Journal ArticleDOI
Barium Toxicity Effects in Soybean Plants
Ryuichi Suwa,Krish Jayachandran,Nguyen Tran Nguyen,Abdellah Boulenouar,Kounosuke Fujita,Hirofumi Saneoka +5 more
TL;DR: The experiment indicates that Ba has phytotoxic effects on soybean plants by inhibiting photosynthesis and photosynthetic activity and plant productivity were inhibited.
Journal ArticleDOI
Characterization of salt tolerance in ectoine-transformed tobacco plants (Nicotiana tabaccum): photosynthesis, osmotic adjustment, and nitrogen partitioning.
Reda E. A. Moghaieb,Nobukazu Tanaka,Hirofumi Saneoka,Y. Murooka,H. Ono,Hiromichi Morikawa,A. Nakamura,Nguyen Tran Nguyen,Ryuichi Suwa,Kounosuke Fujita +9 more
TL;DR: Two ways in which ectoine enhanced salinity tolerance of tobacco plants were revealed, including improved the maintenance of root function so that water is taken up consistently and supplied to shoots under saline conditions and protecting Rubisco proteins from deleterious effects of salt, thereby improving the rate of photosynthesis.
Journal ArticleDOI
Fruits are more sensitive to salinity than leaves and stems in pepper plants (Capsicum annuum L.)
Reona Azuma,Naoko Ito,Nobuhiro Nakayama,Ryuichi Suwa,Nguyen Tran Nguyen,Juan A. Larrinaga-Mayoral,Muneraru Esaka,Hideyasu Fujiyama,Hirofumi Saneoka +8 more
TL;DR: The results suggest that the difference in salt sensitivity between fruits and leaves in pepper plants can be related to the different in inhibition of AsA synthesis, which in turn is probably due to the toxicity of extreme accumulation of Na+.
