Information
- Symbol: OsbHLH38
- MSU: LOC_Os08g33590
- RAPdb: Os08g0432800
Publication
- The basic helix-loop-helix transcription factor gene, OsbHLH38, plays a key role in controlling rice salt tolerance., 2023, J Integr Plant Biol.
Genbank accession number
Key message
- A salt-responsive transcription factor, OsDREB2A, interacted with OsbHLH38 and was directly regulated by OsbHLH38
- Moreover, OsbHLH38 affected rice abiotic stress tolerance by mediating the expression of a large set of transporter genes of phytohormones, transcription factor genes, and many downstream genes with diverse functions, including photosynthesis, redox homeostasis, and abiotic stress responsiveness
- Overexpression of OsbHLH38 increased seedling salt tolerance, while knockout of OsbHLH38 increased sensitivity to salt stress
- These results demonstrated that OsbHLH38 is a key regulator in plant abiotic stress tolerance
- Comprehensive functional analyses using knockout and overexpression transgenic lines revealed that OsbHLH38 expression was responsive to multiple abiotic stresses
