Target Data

Function Participates in ABA-regulated gene expression during seed development and subsequent vegetative stage by acting as the major mediator of ABA repression of growth. Binds to the embryo specification element and the ABA-responsive element (ABRE) of the Dc3 gene promoter and to the ABRE of the Em1 and Em6 genes promoters. Can also trans-activate its own promoter, suggesting that it is autoregulated. Plays a role in sugar-mediated senescence.
Gene References into Functions
  1. SOM is reported to negatively regulate seeds germination by altering GA/ABA metabolism, here we found that AFP2 and ABI5 altered SOM transcription. Data demonstrate that AFP2 is a novel regulator to control high temperature-induced secondary seed dormancy through ABI5 and SOM. PMID: 29723526
  2. These data demonstrate that PHO1 is involved in ABA-mediated seed germination and early seedling development and transcriptionally regulated by ABI5. PMID: 29089393
  3. Arabidopsis MADS-Box Transcription Factor AGL21 Acts as Environmental Surveillance of Seed Germination by Regulating ABI5 Expression PMID: 28438576
  4. ABI5 is a direct target gene of BZR1, and modulating the expression of ABI5 by BZR1 plays important roles in regulating the crosstalk between the brassinosteroid and abscisic acid signalling pathways. PMID: 27149247
  5. NF-YC9 mediates abscisic acid (ABA) signaling via targeting to and aiding the ABA-responsive transcription factors such as ABI5. PMID: 28924726
  6. All of the study findings suggest that ABI5 regulates seed germination at least partly by affecting ROS homeostasis. PMID: 28391398
  7. These results suggested important roles of CRWNs in ABI5 nuclear body organization and ABI5 protein degradation during seed germination. PMID: 26564029

  9. ABI5 bind to the ABR promoter, indicating that ABI5 directly regulates the expression of ABR. The disruption of ABI5 function in abr abi5-1 plants abolished the senescence-accelerating phenotype of the abr mutant, demonstrating that ABI5 is epistatic to ABR. PMID: 27095403

  13. BIN2 phosphorylates and stabilizes ABI5 to mediate Abscisic acid (ABA) response during seed germination, while brassinosteroids (BRs) repress the BIN2-ABI5 cascade to antagonize ABA-mediated inhibition. PMID: 25415975
  14. ubiquitination promotes AB15 degradation; sumoylation prohibits degradation PMID: 24398698
  15. results suggest that ABA negatively regulates SHB1 expression, at least in part, through the action of its downstream signaling component ABI5 PMID: 24619610
