Gene Details:
- Gene ID: HORVU.MOREX.r2.4HG0337680
- Gene Symbol: HvRAF
- Gene Name: root abundant factor
- Genome: MorexV3_pseudomolecules_assembly
- Species: Hordeum vulgare
Functional Descriptions:
- The barley ERF-type transcription factor HvRAF confers enhanced pathogen resistance and salt tolerance in Arabidopsis.
- We isolated HvRAF (Hordeum vulgare root abundant factor), a cDNA encoding a novel ethylene response factor (ERF)-type transcription factor, from young seedlings of barley.
- The fusion protein of HvRAF with the GAL4 DNA-binding domain strongly activated transcription in yeast. Various deletion mutants of HvRAF indicated that the transactivating activity was localized to the acidic domain of the C-terminal region, and that the hemopexin domain signature-like sequence was important for the activity.
- Overexpression of the HvRAF gene in Arabidopsis plants induced the activation of various stress-responsive genes, including PDF1.2, JR3, PR1, PR5, KIN2, and GSH1. Furthermore, the transgenic Arabidopsis plants showed enhanced resistance to Ralstonia solanacearum strain GMI1000, as well as seed germination and root growth tolerance to high salinity.
- These results collectively indicate that HvRAF is a transcription factor that plays dual regulatory roles in response to biotic and abiotic stresses in plants.
