- Key message
- Taken together, these results suggest that OsHKT1;1 has a role in controlling Na(+) concentration and preventing sodium toxicity in leaf blades and is regulated by the OsMYBc transcription factor
- Knockout of OsMYBc resulted in a reduction in NaCl-induced expression of OsHKT1;1 and salt sensitivity
- The transcription factor OsMYBc and an E3 ligase regulate expression of a K+ transporter during salt stress.
- These findings uncover a regulatory mechanism of salt response that fine-tunes OsHKT1;1 transcription by ubiquitination of OsMYBc
- A yeast two-hybrid screen using the OsMYBc N terminus as bait identified a rice MYBc stress-related RING finger protein (OsMSRFP)

- OsROC1~OsMYBc, SDEL1~OsMSRFP, The transcription factor OsMYBc and an E3 ligase regulate expression of a K+ transporter during salt stress., A yeast two-hybrid screen using the OsMYBc N terminus as bait identified a rice MYBc stress-related RING finger protein (OsMSRFP)
- OsROC1~OsMYBc, SDEL1~OsMSRFP, The transcription factor OsMYBc and an E3 ligase regulate expression of a K+ transporter during salt stress., OsMSRFP is an active E3 ligase that ubiquitinated OsMYBc in vitro and mediated 26S proteasome-mediated degradation of OsMYBc under semi-in vitro and in vivo conditions
- OsHKT1;1~OsHKT4, OsROC1~OsMYBc, The transcription factor OsMYBc and an E3 ligase regulate expression of a K+ transporter during salt stress., A member of the High-Affinity K+ Transporter (HKT) family in rice (Oryza sativa), OsHKT1;1, is a vital regulator of Na+ exclusion from shoots and is bound by a MYB transcription factor (OsMYBc)
- OsHKT1;1~OsHKT4, OsROC1~OsMYBc, The transcription factor OsMYBc and an E3 ligase regulate expression of a K+ transporter during salt stress., Here, we generated transgenic rice lines in the oshkt1;1 mutant background for genetic complementation using genomic OsHKT1;1 containing a native (Com) or mutated (mCom) promoter that cannot be bound by OsMYBc
