Journal ArticleDOI
An ABRE promoter sequence is involved in osmotic stress-responsive expression of the DREB2A gene, which encodes a transcription factor regulating drought-inducible genes in Arabidopsis

TL;DR: It is found that both ABRE and coupling element 3 (CE3)-like sequences located approximately -100 bp from the transcriptional initiation site are necessary for the dehydration-responsive expression of DREB2A, and this results suggest that in addition to an ABA-independent pathway, the Aba-dependent pathway plays a positive role in the osmotic stress-responsiveexpression of D REB 2A.
Journal ArticleDOI
Soybean DREB1/CBF-type transcription factors function in heat and drought as well as cold stress-responsive gene expression.
Satoshi Kidokoro,Keitaro Watanabe,Teppei Ohori,Takashi Moriwaki,Kyonoshin Maruyama,Junya Mizoi,Nang Myint Phyu Sin Htwe,Yasunari Fujita,Sachiko Sekita,Kazuo Shinozaki,Kazuko Yamaguchi-Shinozaki +10 more
TL;DR: It is confirmed that GmDREB1B;1 directly activates GmPYL21 expression and enhances ABRE-mediated gene expression in an ABA-independent manner.
Journal ArticleDOI
GmDREB2A;2, a canonical DEHYDRATION-RESPONSIVE ELEMENT-BINDING PROTEIN2-type transcription factor in soybean, is posttranslationally regulated and mediates dehydration-responsive element-dependent gene expression
Junya Mizoi,Teppei Ohori,Takashi Moriwaki,Satoshi Kidokoro,Daisuke Todaka,Kyonoshin Maruyama,Kazuya Kusakabe,Yuriko Osakabe,Kazuo Shinozaki,Kazuko Yamaguchi-Shinozaki +9 more
TL;DR: A new soybean DREB2 gene is identified that was highly induced not only by dehydration and heat but also by low temperature and exhibited a high transactivation activity via DRE and has a serine/threonine-rich region, which corresponds to a negative regulatory domain of DREb2A that is involved in its posttranslational regulation, including destabilization.
Journal ArticleDOI
Arabidopsis DPB3-1, a DREB2A Interactor, Specifically Enhances Heat Stress-Induced Gene Expression by Forming a Heat Stress-Specific Transcriptional Complex with NF-Y Subunits
Hikaru Sato,Junya Mizoi,Hidenori Tanaka,Kyonosin Maruyama,Feng Qin,Yuriko Osakabe,Kyoko Morimoto,Teppei Ohori,Kazuya Kusakabe,Maika Nagata,Kazuo Shinozaki,Kazuko Yamaguchi-Shinozaki +11 more
TL;DR: Results suggest that DPB3-1 could form a transcriptional complex with NF-YA and NF-YB subunits and that the identified trimer enhances heat stress-inducible gene expression during heat stress responses in cooperation with DREB2A.
Journal ArticleDOI
Water deficit and abscisic acid production of Salicornia bigelovii under salinity stress
Teppei Ohori,Hideyasu Fujiyama +1 more
TL;DR: In this paper, the authors investigated the mechanism of growth reduction of dicotyledonous halophyte Salicornia bigelovii under salinity stress by growing it at 0.005 to 500 µm−3 sodium chloride (NaCl).
