- Key message
- OsbHLH058 and OsbHLH059 transcription factors positively regulate iron deficiency responses in rice.
- Subgroup IVc basic helix-loop-helix transcription factors OsbHLH058 and OsbHLH059 positively regulate major iron deficiency responses in rice in a similar but distinct manner, putatively under partial control by OsHRZs
- Transgenic rice lines overexpressing OsbHLH058 showed tolerance for iron deficiency and higher iron concentration in seeds
- In the present study, we investigated the functions of OsbHLH058 and OsbHLH059 related to iron deficiency response
- OsbHLH058 expression was repressed under iron deficiency, whereas the expression of OsbHLH057 and OsbHLH060 was moderately induced
- Conversely, OsbHLH058 knockdown lines showed susceptibility to iron deficiency and reduced expression of many iron deficiency-inducible genes
- These results indicate that OsbHLH058 and OsbHLH059 positively regulate major iron deficiency responses in a similar but distinct manner, and that this function may be partially controlled by OsHRZs
- Connection
- OsbHLH058~OsPRI2, OsHRZ1, OsbHLH058 and OsbHLH059 transcription factors positively regulate iron deficiency responses in rice., Yeast two-hybrid analysis indicated that OsbHLH058 interacts with OsHRZ1 and OsHRZ2 more strongly than OsbHLH060, whereas OsbHLH059 showed no interaction
- OsbHLH058~OsPRI2, OsHRZ1, OsbHLH058 and OsbHLH059 transcription factors positively regulate iron deficiency responses in rice., An in vitro ubiquitination assay detected no OsbHLH058 and OsbHLH060 ubiquitination by OsHRZ1 and OsHRZ2

- OsbHLH058~OsPRI2, OsIMA2, Iron deficiency-inducible peptide coding genes OsIMA1 and OsIMA2 positively regulate a major pathway of iron uptake and translocation in rice, Here, we report that the expressions of two IMA/FEP genes in rice, OsIMA1 and OsIMA2, are strongly induced under Fe-deficiency, positively regulated by the transcription factors IDEF1, OsbHLH058, OsbHLH059, as well as OsIMA1 and OsIMA2 themselves, and negatively regulated by HRZ ubiquitin ligases
