- OsHRZ1, OsPRI1~OsbHLH115, POSITIVE REGULATOR OF IRON HOMEOSTASIS 1 OsPRI1 positively regulates iron homeostasis in rice., In this study, we reveal that OsPRI1 interacts with OsHRZ1
- OsHRZ1, OsPRI1~OsbHLH115, POSITIVE REGULATOR OF IRON HOMEOSTASIS 1 OsPRI1 positively regulates iron homeostasis in rice., In vitro ubiquitination experiments indicated that OsPRI1 is ubiquitinated by OsHRZ1
- OsHRZ1, OsPRI1~OsbHLH115, POSITIVE REGULATOR OF IRON HOMEOSTASIS 1 OsPRI1 positively regulates iron homeostasis in rice., Cell-free degradation assays revealed that the stability of OsPRI1 decreased in wild type roots, but increased in the hrz1-2 mutant, suggesting OsHRZ1 is responsible for the instability of OsPRI1
- OsHRZ1, OsPRI1~OsbHLH115, POSITIVE REGULATOR OF IRON HOMEOSTASIS 1 OsPRI1 positively regulates iron homeostasis in rice., Collectively, these results imply that OsPRI1, which is ubiquitinated by OsHRZ1, mediates rice responses to Fe-deficiency by positively regulating OsIRO2 and OsIRO3 expression as part of the OsHRZ1-OsPRI1-OsIRO2/3 signal transduction cascade
- OsIRO2~OsbHLH056, OsPRI1~OsbHLH115, POSITIVE REGULATOR OF IRON HOMEOSTASIS 1 OsPRI1 positively regulates iron homeostasis in rice., Yeast one-hybrid and electrophoretic mobility shift assay results suggested that OsPRI1 binds to the OsIRO2 and OsIRO3 promoters
- OsIRO2~OsbHLH056, OsPRI1~OsbHLH115, POSITIVE REGULATOR OF IRON HOMEOSTASIS 1 OsPRI1 positively regulates iron homeostasis in rice., Collectively, these results imply that OsPRI1, which is ubiquitinated by OsHRZ1, mediates rice responses to Fe-deficiency by positively regulating OsIRO2 and OsIRO3 expression as part of the OsHRZ1-OsPRI1-OsIRO2/3 signal transduction cascade
- OsIRO3~OsOsbHLH063, OsPRI1~OsbHLH115, POSITIVE REGULATOR OF IRON HOMEOSTASIS 1 OsPRI1 positively regulates iron homeostasis in rice., Yeast one-hybrid and electrophoretic mobility shift assay results suggested that OsPRI1 binds to the OsIRO2 and OsIRO3 promoters
- OsIRO3~OsOsbHLH063, OsPRI1~OsbHLH115, POSITIVE REGULATOR OF IRON HOMEOSTASIS 1 OsPRI1 positively regulates iron homeostasis in rice., Collectively, these results imply that OsPRI1, which is ubiquitinated by OsHRZ1, mediates rice responses to Fe-deficiency by positively regulating OsIRO2 and OsIRO3 expression as part of the OsHRZ1-OsPRI1-OsIRO2/3 signal transduction cascade
- OsbHLH59~OsbHLH059~OsPRI3, OsPRI1~OsbHLH115, Oryza sativa POSITIVE REGULATOR OF IRON DEFICIENCY RESPONSE 2 OsPRI2 and OsPRI3 are involved in the maintenance of Fe homeostasis., In this study, we identified and functionally characterized OsPRI2 and OsPRI3, two paralogs of OsPRI1, observing that they directly interact with OsHRZ1
- OsbHLH061~OsbHLHq11, OsPRI1~OsbHLH115, OsbHLH061 links TOPLESS/TOPLESS-RELATED repressor proteins with POSITIVE REGULATOR OF IRON HOMEOSTASIS 1 to maintain iron homeostasis in rice., The bHLH transcription factor OsbHLH061 interacts with OsPRI1, and this study used molecular, genetics, biochemical and physiological approaches to functionally characterise OsbHLH061 and how it affects Fe homeostasis
- OsbHLH061~OsbHLHq11, OsPRI1~OsbHLH115, OsbHLH061 links TOPLESS/TOPLESS-RELATED repressor proteins with POSITIVE REGULATOR OF IRON HOMEOSTASIS 1 to maintain iron homeostasis in rice., Mechanistically, OsbHLH061 expression is upregulated by high Fe, and physically interacts with OsPRI1, the OsbHLH061-OsPRI1 complex recruits TOPLESS/TOPLESS-RELATED (OsTPL/TPR) co-repressors to repress OsIRO2 and OsIRO3 expression
