- Key message
- These results demonstrate a conserved function of OsBZR1 and an important role of 14-3-3 proteins in brassinosteroid signal transduction in rice
- Functions of OsBZR1 and 14-3-3 proteins in brassinosteroid signaling in rice
- To understand the downstream BR signaling mechanism in rice, we studied the function of OsBZR1 using reverse genetic approaches and identified OsBZR1-interacting proteins
- Suppressing OsBZR1 expression by RNAi resulted in dwarfism, erect leaves, reduced BR sensitivity, and altered BR-responsive gene expression in transgenic rice plants, demonstrating an essential role of OsBZR1 in BR responses in rice
- Finally, consistent with the fact that DLT is also negatively feedback-regulated by BR treatment, a gel mobility shift assay showed that OsBZR1 can bind to the DLT promoter through the BR-response element

- DLT~OsGRAS-32~D62~GS6~SMOS2, OsBZR1, DWARF AND LOW-TILLERING, a new member of the GRAS family, plays positive roles in brassinosteroid signaling in rice, Finally, consistent with the fact that DLT is also negatively feedback-regulated by BR treatment, a gel mobility shift assay showed that OsBZR1 can bind to the DLT promoter through the BR-response element
- ILI1, OsBZR1, Dynamics of brassinosteroid response modulated by negative regulator LIC in rice, LIC directly regulated target genes such as INCREASED LEAF INCLINATION 1 (ILI1) to oppose the action of BZR1
- ILI1, OsBZR1, Dynamics of brassinosteroid response modulated by negative regulator LIC in rice, Repression of LIC in ILI1 transcription in protoplasts was partially rescued by BZR1
- LIC~OsLIC1, OsBZR1, Dynamics of brassinosteroid response modulated by negative regulator LIC in rice, Here, we demonstrate that Oryza sativa LEAF and TILLER ANGLE INCREASED CONTROLLER (LIC) acts as an antagonistic transcription factor of BRASSINAZOLE-RESISTANT 1 (BZR1) to attenuate the BR signaling pathway
- LIC~OsLIC1, OsBZR1, Dynamics of brassinosteroid response modulated by negative regulator LIC in rice, The gain-of-function mutant lic-1 and LIC-overexpressing lines showed erect leaves, similar to BZR1-depleted lines, which indicates the opposite roles of LIC and BZR1 in regulating leaf bending
- LIC~OsLIC1, OsBZR1, Dynamics of brassinosteroid response modulated by negative regulator LIC in rice, For negative feedback, LIC bound to the core element CTCGC in the BZR1 promoter on gel-shift and chromatin immunoprecipitation assay and repressed its transcription on transient transformation assay
- LIC~OsLIC1, OsBZR1, Dynamics of brassinosteroid response modulated by negative regulator LIC in rice, LIC directly regulated target genes such as INCREASED LEAF INCLINATION 1 (ILI1) to oppose the action of BZR1
- LIC~OsLIC1, OsBZR1, Dynamics of brassinosteroid response modulated by negative regulator LIC in rice, Repression of LIC in ILI1 transcription in protoplasts was partially rescued by BZR1
- LIC~OsLIC1, OsBZR1, Dynamics of brassinosteroid response modulated by negative regulator LIC in rice, Phenotypic analysis of the crossed lines depleted in both LIC and BZR1 suggested that BZR1 functionally depends on LIC
- LIC~OsLIC1, OsBZR1, Dynamics of brassinosteroid response modulated by negative regulator LIC in rice, Molecular and physiology assays revealed that LIC plays a dominant role at high BR levels, whereas BZR1 is dominant at low levels
- LIC~OsLIC1, OsBZR1, Dynamics of brassinosteroid response modulated by negative regulator LIC in rice, Thus, LIC regulates rice leaf bending as an antagonistic transcription factor of BZR1
- CSA, OsBZR1, Brassinosteroids Promote Development of Rice Pollen Grains and Seeds by Triggering Expression of CSA, a MYB Domain Protein., Mechanically, OsBZR1 directly promotes CSA expression and CSA directly triggers expression of sugar partitioning and metabolic genes during pollen and seed development
- OsBZR1, OsDof12~OsCDF1, Overexpression of OsDof12 affects plant architecture in rice Oryza sativa L.., Of note, in WT plants the expression of OsDof12 was found up-regulated by BR treatment while in OsDof12 overexpression plants two positive BR signaling regulators, OsBRI1 and OsBZR1, were significantly down-regulated, indicating that OsDof12 may act as a negative BR regulator in rice
- OsBZR1, OsPRA2, A Small G Protein as a Novel Component of the Rice Brassinosteroid Signal Transduction., Mechanistic study uncovered that OsPRA2 inhibited the dephosphorylation of, and thus inactivated the transcription factor BRASSINAZOLE-RESISTANT 1 (OsBZR1)
- OsBZR1, OsPRA2, A Small G Protein as a Novel Component of the Rice Brassinosteroid Signal Transduction., Together, these results revealed a possible working mechanism of OsPRA2 as a novel negative regulator on OsBRI1 and OsBZR1 in the BR signaling pathway in rice, and further extended the knowledge about the regulatory mechanism of rice BR signaling
- GW5~qSW5, OsBZR1, GW5 acts in the brassinosteroid signalling pathway to regulate grain width and weight in rice., GW5 protein is localized to the plasma membrane and can physically interact with and repress the kinase activity of rice GSK2 (glycogen synthase kinase 2), a homologue of Arabidopsis BIN2 (BRASSINOSTEROID INSENSITIVE2) kinase, resulting in accumulation of unphosphorylated OsBZR1 (Oryza sativa BRASSINAZOLE RESISTANT1) and DLT (DWARF AND LOW-TILLERING) proteins in the nucleus to mediate brassinosteroid (BR)-responsive gene expression and growth responses (including grain width and weight)
- OsBZR1, OsPRA2, OsPRA2 fine-tunes rice brassinosteroid receptor., Recently we have reported that a rice small G protein, OsPRA2, bound to the BR receptor OsBRI1 at the plasma membrane (PM) and inhibited its kinase activity and its interaction with the co-receptor OsBAK1, leading to a lower sensitivity to BR treatment and dephosphorylation of OsBZR1
- OFP1, OsBZR1, Brassinosteroids Regulate OFP1, a DLT Interacting Protein, to Modulate Plant Architecture and Grain Morphology in Rice., In addition, we found OFP1 was greatly induced by BR treatment, and OsBZR1, the critical transcription factor of BR signaling, was physically associated with the OFP1 promoter
