- Key message
- Here we report the identification of new iron regulators in rice, designated Oryza sativa Haemerythrin motif-containing Really Interesting New Gene (RING)- and Zinc-finger protein 1 (OsHRZ1) and OsHRZ2
- OsHRZ1, OsHRZ2 and their Arabidopsis homologue BRUTUS bind iron and zinc, and possess ubiquitination activity
- OsHRZ1 and OsHRZ2 are susceptible to degradation in roots irrespective of iron conditions
- These results suggest that OsHRZ1 and OsHRZ2 are iron-binding sensors that negatively regulate iron acquisition under conditions of iron sufficiency
- Many jasmonate-inducible genes were also negatively regulated by the ubiquitin ligases OsHRZ1 and OsHRZ2 and positively regulated by the transcription factor IDEF1
- C1 (OE) rice plants modify the expression of the putative iron-sensing factors OsHRZ1 and OsHRZ2 and enhance the expression of OsIRO2 under copper excess, which suggests a role of copper transport in iron signaling

- OsHRZ1, OsPRI1, 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, 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, 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, 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
