Journal ArticleDOI
A dehydration‐induced NAC protein, RD26, is involved in a novel ABA‐dependent stress‐signaling pathway
Miki Fujita,Yasunari Fujita,Kyonoshin Maruyama,Motoaki Seki,Keiichiro Hiratsu,Masaru Ohme-Takagi,Lam-Son Phan Tran,Kazuko Yamaguchi-Shinozaki,Kazuo Shinozaki +8 more
TL;DR: Results indicate that RD26 functions as a transcriptional activator in ABA-inducible gene expression under abiotic stress in plants.
Journal ArticleDOI
AREB1 Is a Transcription Activator of Novel ABRE-Dependent ABA Signaling That Enhances Drought Stress Tolerance in Arabidopsis
Yasunari Fujita,Miki Fujita,Rie Satoh,Kyonoshin Maruyama,Mohammad Masud Parvez,Motoaki Seki,Keiichiro Hiratsu,Masaru Ohme-Takagi,Kazuo Shinozaki,Kazuko Yamaguchi-Shinozaki +9 more
TL;DR: It is shown that expression of the intact AREB1 gene on its own is insufficient to lead to expression of downstream genes under normal growth conditions, and data suggest that AREB 1 regulates novel ABRE-dependent ABA signaling that enhances drought tolerance in vegetative tissues.
Journal ArticleDOI
Repression Domains of Class II ERF Transcriptional Repressors Share an Essential Motif for Active Repression
TL;DR: Analysis of the results of a series of deletions revealed that the C-terminal 35 amino acids of NtERF3 are sufficient to confer the capacity for repression of transcription on a heterologous DNA binding domain, and this repression domain suppressed the intermolecular activities of other transcriptional activators.
Journal ArticleDOI
Dominant repression of target genes by chimeric repressors that include the EAR motif, a repression domain, in Arabidopsis.
TL;DR: It is shown that four different transcription factors fused to the EAR motif act as dominant repressors in transgenic Arabidopsis and suppress the expression of specific target genes, even in the presence of the redundant transcription factors, with resultant dominant loss-of-function phenotypes.
Journal ArticleDOI
The AP2/ERF Transcription Factor WIND1 Controls Cell Dedifferentiation in Arabidopsis
Akira Iwase,Nobutaka Mitsuda,Tomotsugu Koyama,Tomotsugu Koyama,Keiichiro Hiratsu,Keiichiro Hiratsu,Mikiko Kojima,Takashi Arai,Yasunori Inoue,Motoaki Seki,Hitoshi Sakakibara,Keiko Sugimoto,Masaru Ohme-Takagi +12 more
TL;DR: Novel molecular insights are provided into how plants control cell dedifferentiation in response to wounding by demonstrating that wounding upregulates the B-type ARABIDOPSIS RESPONSE REGULATOR (ARR)-mediated cytokinin response and that WIND1 acts via the ARR-dependent signaling pathway to promote cell ded indifferentiation.
