Journal ArticleDOI
Nuclear-localized BZR1 mediates brassinosteroid-induced growth and feedback suppression of brassinosteroid biosynthesis.
Zhi-Yong Wang,Takeshi Nakano,Joshua M. Gendron,Joshua M. Gendron,Jun-Xian He,Meng Chen,Dionne Vafeados,Yanli Yang,Shozo Fujioka,Shigeo Yoshida,Tadao Asami,Joanne Chory +11 more
TL;DR: The results demonstrate that BZR1 is a positive regulator of the BR signaling pathway that mediates both downstream BR responses and feedback regulation of BR biosynthesis.
Journal ArticleDOI
A new class of transcription factors mediates brassinosteroid-regulated gene expression in Arabidopsis.
TL;DR: It is established that BES1 is a transcription factor that binds to and activates BR target gene promoters both in vitro and in vivo and defines a new class of plant-specific transcription factors that cooperate with transcription factors such as BIM1 to regulate BR-induced genes.
Journal ArticleDOI
BRL1 and BRL3 are novel brassinosteroid receptors that function in vascular differentiation in Arabidopsis.
Ana I. Caño-Delgado,Yanhai Yin,Cong Yu,Dionne Vafeados,Santiago Mora-García,Jin-Chen Cheng,Kyoung Hee Nam,Kyoung Hee Nam,Jianming Li,Joanne Chory +9 more
TL;DR: Arabidopsis contains a small number of BR receptors that have specific functions in cell growth and vascular differentiation, and only BRL1 and BRL3 can rescue bri1 mutants when expressed under the control of the BRI1 promoter.
Journal ArticleDOI
Alteration of stimulus-specific guard cell calcium oscillations and stomatal closing in Arabidopsis det3 mutant.
Gethyn J. Allen,Sarah P. Chu,Karin Schumacher,Chad T. Shimazaki,Dionne Vafeados,Andrea Kemper,Scott D. Hawke,Gary Tallman,Roger Y. Tsien,Jeffrey F. Harper,Joanne Chory,Julian I. Schroeder +11 more
TL;DR: Genetic evidence is provided that stimulus-specific calcium oscillations are necessary for stomatal closure in guard cells of the V-ATPase mutant det3.
Journal ArticleDOI
BIN2, a New Brassinosteroid-Insensitive Locus in Arabidopsis
TL;DR: In this article, the authors identify a semidwarf mutant that showed little response to exogenous BR treatments and showed BR-insensitivity when assayed for root growth inhibition and feedback inhibition of CPD gene expression.
