Our re-sults thus showed that ABA regulates early seed development by ABI5-regulated SHB1 expression. RESULTS 2020-09-07 2020-03-02 Beyond germination, ABA further inhibits postgermination seedling development, which is often mediated by the transcription factor ABSCISIC ACID INSENSTIVE5 (ABI5) (Chen et al., 2020). Recent investigations have unravelled the importance of light–ABA interactions in postgermination development and environmental adaptability of seedlings. However, ABI5 was found to modulate the PYL11‐ and PYL12‐mediated ABA response.

Abi5 aba

In this study, we found that MdABI5, the apple homolog of Arabidopsis ABI5, positively regulated ABA-induced anthocyanin biosynthesis. In the abi5-7 mutant, ABA hypersensitivity caused by PYL11 and PYL12 overexpression was totally or partially blocked. By contrast, ABI5 regulates the expression of PYL11 and PYL12 by directly binding to their promoters. Moreover, the expression of eight other PYLs is also affected during the germination of abi5 mutants.

Convergence of Light and ABA signaling on the ABI5 - GUP

Responsible for reducing cadmium uptake, mediated by interaction with MYB49 . Other Gene Models The accumulated ABI5 protein further shows heteromeric interaction with HY5, and thus synergistically activates its own expression. Our findings reveal a novel transcriptional switch, composed of JMJ17-WRKY40 and HY5-ABI5 modules, which regulates the ABA response during seed germination and seedling development in Arabidopsis. Moreover, although ABI5 protein levels were higher in darkness than in the light within 2 h of ABA treatment, we observed an obvious decrease in ABI5 protein levels after prolonged (e.g., 12 h) ABA treatment, whereas in the light ABI5 continued to accumulate within 12 h of ABA treatment (Figure 2B and 2C). ABA INSENSITIVE 5 (ABI5) is a basic leucine zipper (bZIP) transcription factor which acts in the abscisic acid (ABA) network and is activated in response to abiotic stresses.

Our re-sults thus showed that ABA regulates early seed development by ABI5-regulated SHB1 expression.

Although ABI5 is consistently located in the nucleus, chromosomal immunoprecipitation (ChIP) experiments revealed that ABA increases ABI5 occupancy on the AtEm6 promoter. 2001-04-10 ABI5 Encodes a Basic Leucine Zipper Transcription Factor Ruth R. Finkelstein 1 and Tim J. Lynch Department of Molecular, Cellular and Developmental Biology, University of California–Santa Barbara, Santa Barbara, California 93106 The Arabidopsis abscisic acid (ABA)–insensitive abi5 mutants have pleiotropic defects in ABA response, including de- The Arabidopsis abscisic acid (ABA)-insensitive abi5 mutants have pleiotropic defects in ABA response, including decreased sensitivity to ABA inhibition of germination … ABI5 HY5 Light ABA BBX21 ABI5 PYR/PYL/RCAR PP2C SnRK2 COP1 FHY3 DET1 +1 HRB2 HDA6 ABI5 ABI5 HRB2 HDA6 DDA1 ABA-response genes PIF1,3,4,5 PIF1,3,4,5 Fig.1 A model showing molecular interactions between light and abscisic acid (ABA) signalling pathways during … 2009-07-28 2001-04-10 2016-09-14 Correspondingly, the seed germination from two independent gim1 ABI5‐5 hybrid lines, gim1 ABI5‐5(A) and gim1 ABI5‐5(E), showed hypersensitivity to ABA . In contrast, the gim1 abi5‐4 double mutant showed a similar germination phenotype in comparison with its parental gim1 and abi5‐4 mutants . 2019-12-02 ABA-responsive through ABI5-dependent signaling (e.g., RD29A, Rd29B, AtEm6, RAB18, ADH1) was hyperinduced by the hormone in siz1 seedlings. abi5–4 suppressed ABA hypersensitivity caused by siz1 (siz1–2 abi5–4), demonstrating an epistatic genetic inter-action between SIZ1 and ABI5.

In addition, ABI5 was shown to directly activate its own expression, whereas BBX21 negatively regulates this activity by directly interacting with ABI5. Together, our study indicates that BBX21 coordinates with HY5 and ABI5 on the ABI5 promoter and that these transcriptional regulators work in concert to integrate light and ABA signaling in Arabidopsis thaliana. Studies have identified the key components of ABA signaling in Arabidopsis (Arabidopsis thaliana), some of which regulate ABA responses by the transcriptional regulation of downstream genes. Here, we report the functional identification of rice (Oryza sativa) ABI5-Like1 (ABL1), which is a basic region/leucine zipper motif transcription factor.
