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
Integration of Brassinosteroid Signal Transduction with the Transcription Network for Plant Growth Regulation in Arabidopsis
Yu Sun,Xiying Fan,Xiying Fan,Dong Mei Cao,Wenqiang Tang,Kun He,Jia Ying Zhu,Jun-Xian He,Ming-Yi Bai,Ming-Yi Bai,Shengwei Zhu,Eunkyoo Oh,Sunita Patil,Tae-Wuk Kim,Hongkai Ji,Wing H. Wong,Seung Y. Rhee,Zhi-Yong Wang +17 more
TL;DR: This work uses transcript profiling and chromatin-immunoprecipitation microarray experiments to identify 953 BR-regulated BZR1 target (BRBT) genes and reveals a regulatory network that integrates hormonal and light-signaling pathways for plant growth regulation.
Journal ArticleDOI
BZR1 Is a Transcriptional Repressor with Dual Roles in Brassinosteroid Homeostasis and Growth Responses
Jun-Xian He,Joshua M. Gendron,Joshua M. Gendron,Yu Sun,Srinivas S. Gampala,Nathan Gendron,Catherine Q. Sun,Zhi-Yong Wang +7 more
TL;DR: It is shown that BZR1 is a transcriptional repressor that has a previously unknown DNA binding domain and binds directly to the promoters of feedback-regulated BR biosynthetic genes.
Journal ArticleDOI
The GSK3-like kinase BIN2 phosphorylates and destabilizes BZR1, a positive regulator of the brassinosteroid signaling pathway in Arabidopsis
TL;DR: It is reported that BRs induce dephosphorylation and accumulation of BZR1 protein and that BR signaling causes BzR1 deph phosphorylated and accumulation by inhibiting BIN2 activity.
Journal ArticleDOI
An Essential Role for 14-3-3 Proteins in Brassinosteroid Signal Transduction in Arabidopsis
Srinivas S. Gampala,Tae-Wuk Kim,Jun-Xian He,Wenqiang Tang,Zhiping Deng,Mingyi-Yi Bai,Shenheng Guan,Sylvie Lalonde,Ying Sun,Ying Sun,Joshua M. Gendron,Joshua M. Gendron,Huanjing Chen,Nakako Shibagaki,Robert J. Ferl,David W. Ehrhardt,Kang Chong,Alma L. Burlingame,Zhi-Yong Wang +18 more
TL;DR: It is shown that BIN2-catalyzed phosphorylation of BZR1/BZR2 not only inhibits DNA binding, but also promotes binding to the 14-3-3 proteins.
