- Key message
- The stress-related genes activated by OsbZIP46CA1 are largely different from those activated by the other rice ABF/AREB homologs (such as OsbZIP23), further implying the value of OsbZIP46CA1 in genetic engineering of drought tolerance
- Constitutive activation of transcription factor OsbZIP46 improves drought tolerance in rice
- A homozygous T-DNA insertional mutant of OsABF2 is more sensitive to salinity, drought, and oxidative stress compared with wild type plants
- In addition, the abl1 mutant is hypersensitive to exogenous indole-3-acetic acid, and some ABRE-containing genes related to auxin metabolism or signaling are altered under ABL1 deficiency, suggesting that ABL1 modulates ABA and auxin responses by directly regulating the ABRE-containing genes
- Overexpression of the native OsbZIP46 gene increased ABA sensitivity but had no positive effect on drought resistance
- These results suggest that OsbZIP46 is a positive regulator of ABA signaling and drought stress tolerance of rice depending on its activation
- Together, it is suggested that a nuclear PP2C protein OsSIPP2C1 negatively regulated by ABL1 is involved in abiotic stress and panicle development in rice
- A novel nuclear protein phosphatase 2C negatively regulated by ABL1 is involved in abiotic stress and panicle development in rice
- Due to the dates, OsAREB1 may function as a positive regulator in drought/heat stresses response, but a negative regulator in flowering time in Arabiclopsis
- OsSIPP2C1 expression was up-regulated by high salt, PEG6000 and exogenous ABA, and enhanced in the abl1 mutant under normal, salt, or drought condition
- ABL1 is expressed in various tissues and is induced by the hormones ABA and indole-3-acetic acid and stress conditions including salinity, drought, and osmotic pressure
- Expression of OsbZIP46 was strongly induced by drought, heat, hydrogen peroxide, and abscisic acid (ABA) treatment; however, it was not induced by salt and cold stresses
- Overexpression of OsbZIP46CA1 in rice significantly increased tolerance to drought and osmotic stresses
- The ABL1 deficiency mutant, abl1, shows suppressed ABA responses, and ABL1 expression in the Arabidopsis abi5 mutant rescued the ABA sensitivity
- Trdnsgenic Arabidopsis over-expressing OsAREB1 had different responses to ABA and glucose compared to wild-type plants, which suggest OsAREB1 might have a crucial role in these two signaling pathways
- OsAREB1, an ABRE-binding protein responding to ABA and glucose, has multiple functions in Arabidopsis
- In our current study, we have isolated and characterized a group A bZIP transcription factor in rice, OsABF2 (Oryza sativa ABA-responsive element binding factor 2)
- The ABRE-binding bZIP transcription factor OsABF2 is a positive regulator of abiotic stress and ABA signaling in rice
- Here, we report the functional identification of rice (Oryza sativa) ABI5-Like1 (ABL1), which is a basic region/leucine zipper motif transcription factor
- Collectively, our present results indicate that OsABF2 functions as a transcriptional regulator that modulates the expression of abiotic stress-responsive genes through an ABA-dependent pathway
- Purification, crystallization and preliminary X-ray analysis of OsAREB8 from rice, a member of the AREB/ABF family of bZIP transcription factors, in complex with its cognate DNA
- First, OsAREB1 transgenic plants had higher resistance to drought and heat, and OsAREB1 up-regulated the ABA/stress related gene such as RD29A and RD29B
- In addition, this Osabf2 mutant showed a significantly decreased sensitivity to high levels of ABA at germination and post-germination
- OsbZIP46 is one member of the third subfamily of bZIP transcription factors in rice (Oryza sativa)
- SiMYB19 overexpression promotes abscisic acid (ABA) accumulation in transgenic rice and upregulates the ABA synthesis gene OsNCED3 and the ABA signal transduction pathway-related genes OsPK1 and OsABF2
- Further investigation revealed that the transcription factor basic region and leucine zipper 46 (OsbZIP46), involved in ABA signaling, can directly bind to the YUCCA8/rice ethylene-insensitive 7 (OsYUC8/REIN7) promoter to activate its expression, and genetic analysis revealed that OsYUC8/REIN7 is located downstream of OsbZIP46
