- Publication
- Comprehensive analysis of rice DREB2-type genes that encode transcription factors involved in the expression of abiotic stress-responsive genes, 2010, Mol Genet Genomics.
- OsDREB2B, an AP2/ERF transcription factor, negatively regulates plant height by conferring GA metabolism in rice., 2022, Front Plant Sci.
- Genbank accession number
- Key message
- Transgenic Arabidopsis plants overexpressing OsDREB2B showed enhanced expression of DREB2A target genes and improved drought and heat-shock stress tolerance
- These results suggest that OsDREB2B is a key gene that encodes a stress-inducible DREB2-type transcription factor that functions in stress-responsive gene expression in rice
- Only OsDREB2A and OsDREB2B showed abiotic stress-inducible gene expression
- Spatial expression analysis revealed that OsDREB2B was highly expressed in the leaf sheaths
- Under exogenous GA(3) application, OsDREB2B expression was induced, and the length of the second leaf sheath of the OsDREB2B-OE lines recovered to that of the WT
- In summary, our study suggests that OsDREB2B plays a negative role in rice growth and development by regulating GA metabolic gene expression, which is mediated by OsAP2-39 and OsWRKY21, thereby reducing GA content and rice plant height
- OsDREB2B localized to the nucleus of the rice protoplast acted as a transcription activator and upregulated OsAP2-39 by directly binding to its promoter
- Connection
- OsDREB2B, OsMKK1~OsMEK2, The mitogen-activated protein kinase cascade MKK1-MPK4 mediates salt signaling in rice., By comparing the transcription factors levels between WT and osmkk1 mutant, OsMKK1 was necessary for salt-induced increase in OsDREB2B and OsMYBS3
- OsDREB2B, OsJRL, OsJRL, a rice jacalin-related mannose-binding lectin gene, enhances Escherichia coli viability under high-salinity stress and improves salinity tolerance of rice., Overexpression of OsJRL in rice also enhanced salinity tolerance and increased the expression levels of a number of stress-related genes, including three LEA (late embryogenesis abundant proteins) genes (OsLEA19a, OsLEA23 and OsLEA24), three Na(+) transporter genes (OsHKT1;3, OsHKT1;4 and OsHKT1;5) and two DREB genes (OsDREB1A and OsDREB2B)

- OsAP2-39, OsDREB2B, OsDREB2B, an AP2/ERF transcription factor, negatively regulates plant height by conferring GA metabolism in rice., In summary, our study suggests that OsDREB2B plays a negative role in rice growth and development by regulating GA metabolic gene expression, which is mediated by OsAP2-39 and OsWRKY21, thereby reducing GA content and rice plant height
- OsDREB2B, OsWRKY21, OsDREB2B, an AP2/ERF transcription factor, negatively regulates plant height by conferring GA metabolism in rice., The yeast two-hybrid assay and bimolecular fluorescence complementation assay showed that OsDREB2B interacted with OsWRKY21
- OsDREB2B, OsWRKY21, OsDREB2B, an AP2/ERF transcription factor, negatively regulates plant height by conferring GA metabolism in rice., In summary, our study suggests that OsDREB2B plays a negative role in rice growth and development by regulating GA metabolic gene expression, which is mediated by OsAP2-39 and OsWRKY21, thereby reducing GA content and rice plant height
