Journal ArticleDOI
AtSWEET13 and AtSWEET14 regulate gibberellin-mediated physiological processes
Yuri Kanno,Takaya Oikawa,Yasutaka Chiba,Yasuhiro Ishimaru,Takafumi Shimizu,Naoto Sano,Tomokazu Koshiba,Yuji Kamiya,Minoru Ueda,Mitsunori Seo +9 more
TL;DR: Evidence is provided that Arabidopsis SWEET proteins, AtSWEET13 and AtS WEET14, which are members of a family that had previously been linked to sugar transport, are able to mediate cellular GA uptake when expressed in yeast and oocytes, and suggest that At sWEET 13 and AtsWEET14 may be involved in modulating GA response in Arabidoptera.
Journal ArticleDOI
The jasmonate-responsive GTR1 transporter is required for gibberellin-mediated stamen development in Arabidopsis
Hikaru Saito,Takaya Oikawa,Shin Hamamoto,Yasuhiro Ishimaru,Miyu Kanamori-Sato,Yuko Sasaki-Sekimoto,Tomoya Utsumi,Jing Chen,Yuri Kanno,Shinji Masuda,Yuji Kamiya,Mitsunori Seo,Nobuyuki Uozumi,Minoru Ueda,Hiroyuki Ohta +14 more
TL;DR: It is reported that a major glucosinolate transporter, GTR1/NPF2, is multifunctional and may be involved in hormone transport in Arabidopsis thaliana and may positively regulate stamen development by mediating gibberellin supply.
Journal ArticleDOI
Jasmonate signaling is activated in the very early stages of iron deficiency responses in rice roots
Takanori Kobayashi,Takanori Kobayashi,Reiko Nakanishi Itai,Takeshi Senoura,Takaya Oikawa,Yasuhiro Ishimaru,Minoru Ueda,Hiromi Nakanishi,Naoko K. Nishizawa +8 more
TL;DR: Results indicate that jasmonate signaling is activated during the very early stages of iron deficiency, which is partly regulated by IDEF1 and OsHRZs.
Journal ArticleDOI
Iron deficiency regulated OsOPT7 is essential for iron homeostasis in rice
Khurram Bashir,Yasuhiro Ishimaru,Yasuhiro Ishimaru,Reiko Nakanishi Itai,Takeshi Senoura,Michiko Takahashi,Gynheung An,Takaya Oikawa,Minoru Ueda,Aiko Sato,Nobuyuki Uozumi,Hiromi Nakanishi,Naoko K. Nishizawa,Naoko K. Nishizawa +13 more
TL;DR: Results indicate that OsOPT7 may be involved in Fe transport in rice, and the upregulation of Fe-deficiency-responsive genes in plants grown under Fe-sufficient conditions is revealed, despite the high Fe and ferritin concentrations in shoot tissue indicating that Fe may not be available for physiological functions.
Journal ArticleDOI
GTR1 is a jasmonic acid and jasmonoyl-l-isoleucine transporter in Arabidopsis thaliana
Yasuhiro Ishimaru,Takaya Oikawa,Takeshi Suzuki,Syohei Takeishi,Hideyuki Matsuura,Kosaku Takahashi,Shin Hamamoto,Nobuyuki Uozumi,Takafumi Shimizu,Mitsunori Seo,Hiroyuki Ohta,Minoru Ueda +11 more
TL;DR: It is found that a JA-Ile transporter, GTR1, contributed to these translocations in Arabidopsis thaliana and may be contributed to correct positioning of JA and JA- Ile to attenuate an excessive wound response in undamaged leaves.
