2020-03-02 · Moreover, we observed that on 0.3 μM ABA, growth of abi5 pifq mutant seedlings was more resistant to ABA than that of pifq mutants, but similar to that of abi5 (Figure 4D). These observations indicate that ABI5 is epistatic to PIFs in mediating hypocotyl-negative gravitropism and ABA signaling in darkness. 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. 2020-09-07 · We then measured ABI5 protein levels in seeds that were treated with ABA for 48 h.

ABI5 functions in the core ABA signaling, which is composed of PYR/PYL/RCAR receptors, PP2C phosphatases and SnRK2 kinases, through the 2018-02-20 · ABA induces a number of effectors, including the bZIP transcription factor ABA INSENSITIVE5 (ABI5). ABI5 accumulates during seed maturation and in dry seeds [19, 20]. During the normal course of seed germination, ABA and concomitantly ABI5 levels rapidly decline following imbibition and GA biosynthesis, enabling seed germination. The Arabidopsis abscisic acid (ABA)-insensitive abi5 mutants have pleiotropic gene expression in wild-type and abi5-1 plants indicates that ABI5 regulates a We used cDNA microarrays to analyze ABA regulated gene expression and the role of ABI5 in seedlings. 310 genes were identified as.

ABA Insensitive 5 (ABI5) is a basic leucine zipper transcription factor that plays a key role in the regulation of seed germination and early seedling growth in the presence of ABA and abiotic stresses. ABI5 functions in the core ABA signaling, which is composed of PYR/PYL/RCAR receptors, PP2C phosphatases and SnRK2 kinases, through the regulation ABI5 modulates seed germination via feedback regulation of the expression of the PYR/PYL/RCAR ABA receptor genes.

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. ABI5 is tightly controlled by the core ABA signaling components and many other regulators.
