In this study, BRI1-GFP was observed in the endosomes in root cells of transgenic Arabidopsis, independent of BR levels. Blocking trafficking from early to late endosomal compartments causes accumulation of BRI1-GFP in endosomal compartments and activation of BR signaling. It was concluded that BRI1 can signal from endosomes.

In this study, a mutant BRI1 (bri1-9) was found to be retained in the ER. A suppressor of bri1-9 (ebs1) contains a mutation in a UDP-glucose:glycoprotein glucosyltransferase, which promotes retention of mis-folded proteins in the ER. The ebs1 mutation restored plasma membrane localization of bri1-9.

Curr Biol 17 (2007) 1109-1115. In this study, BKK1/SERK4, the closest homolog of BAK1, interacts with BRI1 and suppresses bri1-5 when overexpressed, suggesting a similar function as BAK1 in BR signaling. Surprisingly, the bak1/bkk1 double mutant shows a seedling lethal phenotype because of cell death. When grown in the dark, the double mutant shows a weak de-etiolation phenotype. The results indicate that BAK1 and BKK1 play redundant roles in both BR signaling and cell death control.

The BRI1-associated kinase 1, BAK1, Has a brassinolide-independent role in plant cell-death control. Curr Biol 17 (2007) 1116-1122. In this study, the bak1 mutant develops spreading necrosis upon pathogen infection, accompanied by production of reactive oxygen intermediates. BL rescues the growth defects of bak1 but has no effect on its disease phenotypes, suggesting that BAK1 has a BR-independent function in plant cell death control.

Nature 448 (2007) 497-500. In this study, the bak1 mutant shows reduced sensitivity to pathogen-associated molecular patterns, including flagellin and Ef-Tu, but normal flagellin-binding activity in the plasma membrane. BAK1 interacts with the flagellin receptor FLS2 upon flagellin treatment, indicating that BAK1 is involved in flagellin signaling as well as BR signaling.

The receptor-like kinase SERK3/BAK1 is a central regulator of innate immunity in plants. Proc Natl Acad Sci USA 104 (2007) 12217-12222. In this study, similar to the above study, BAK1 interacts with FLS2 upon flagellin treatment. Silencing BAK1 expression reduces defense responses to pathogen infection.

It was shown that phosphorylation of BZR2/BES1 inhibited DNA-binding activity in vitro and transcription activity in yeast but did not affect the accumulation or nuclear localization of BES1. BIN2 is able to act in the nucleus, but its accumulation is not affected by BR.

An essential role for 14-3-3 proteins in brassinosteroid signal transduction in Arabidopsis. Dev Cell 13 (2007) 177-189. BR induces nuclear localization of BZR1 and BZR2/BES1. BIN2-catalyzed phosphorylation of BZR1 inhibits DNA binding and promotes interaction with the 14-3-3 proteins. Mutation of a BIN2 phosphorylation site of BZR1 (S173A) abolished 14-3-3 binding, and caused BR-activation phenotypes and constitutive nuclear localization of BZR1. The study demonstrates an essential role of 14-3-3 proteins in regulation of BZR1 nuclear localization by BR-induced dephosphorylation.

Proc Natl Acad Sci USA 104 (2007) 13839-13844. In this study, the rice homolog of BZR1 (OsBZR1) was shown to be essential for BR responses in rice. Yeast two-hybrid screens identified all eight rice 14-3-3 proteins as OsBZR1-interacting proteins. Mutation of a 14-3-3-binding site in OsBZR1 abolished the interaction with 14-3-3 proteins, and expression of the mutant OsBZR1, which has increased nuclear localization, suppressed bri1-5 phenotypes. The study demonstrates a conserved mechanism for BR signaling in dicots and monocots, and reveals a novel role for 14-3-3 proteins in BR signaling.

Development 134 (2007) 2841-2850. In this study, new bri1 alleles were identified as enhancers of the late-flowering autonomous-pathway mutant luminidependens. The late flowering phenotypes of bri1 and cpd mutants were shown to be because of increased expression of the flowering repressor FLC.

In this study, expression of BRI1 in the epidermis rescues bri1's dwarf phenotype more effectively than expression in vascular tissues. The authors show that BR-mediated expansion of cells in the epidermis drives expansion of the whole plant.
