Journal ArticleDOI
EIN2, a bifunctional transducer of ethylene and stress responses in Arabidopsis.
TL;DR: expression of the EIN2 CEND is sufficient to constitutively activate ethylene responses and restores responsiveness to jasmonic acid and paraquat-induced oxygen radicals to mutant plants, and Ein2 is recognized as a molecular link between previously distinct hormone response pathways.
Journal ArticleDOI
Research on plant abiotic stress responses in the post‐genome era: past, present and future
Takashi Hirayama,Kazuo Shinozaki +1 more
TL;DR: Recent progress in abiotic stress studies, especially in the post-genomic era, is summarized, new perspectives on research directions for the next decade are offered, and the availability of the complete genome sequence has facilitated access to essential information.
Journal ArticleDOI
Type 2C protein phosphatases directly regulate abscisic acid-activated protein kinases in Arabidopsis
Taishi Umezawa,Naoyuki Sugiyama,Masahide Mizoguchi,Shimpei Hayashi,Fumiyoshi Myouga,Kazuko Yamaguchi-Shinozaki,Yasushi Ishihama,Takashi Hirayama,Kazuo Shinozaki +8 more
TL;DR: It is demonstrated that group A PP2Cs act as ‘gatekeepers’ of subclass III SnRK2s, unraveling an important regulatory mechanism of ABA signaling.
Journal ArticleDOI
A Transmembrane Hybrid-Type Histidine Kinase in Arabidopsis Functions as an Osmosensor
Takeshi Urao,Bakhtiyor Yakubov,Rie Satoh,Kazuko Yamaguchi-Shinozaki,Motoaki Seki,Takashi Hirayama,Kazuo Shinozaki +6 more
TL;DR: Results imply that ATHK1 functions as an osmosensor and transmits the stress signal to a downstream MAPK cascade.
Journal ArticleDOI
A gene encoding a mitogen-activated protein kinase kinase kinase is induced simultaneously with genes for a mitogen-activated protein kinase and an S6 ribosomal protein kinase by touch, cold, and water stress in Arabidopsis thaliana.
Tsuyoshi Mizoguchi,Kenji Irie,Takashi Hirayama,Nobuaki Hayashida,Kazuko Yamaguchi-Shinozaki,Kunihiro Matsumoto,Kazuo Shinozaki +6 more
TL;DR: The cloning and characterization of a cDNA encoding a protein kinase that has high sequence homology to members of the mitogen-activated protein kinases (MAPK) kinase kinase (MAPKKK or MEKK) family are described and results suggest that MAP kinase cascades in plants may function in transducing signals in the presence of environmental stress.
