Genetic analysis shows that abi5-4 is epistatic toafp-1, indicating the ABA hypersensitivity of afpmutants requires ABI5. Proteasome inhibitor studies show that

Comparison of seed and ABA-inducible vegetative gene expression in wild-type and abi5-1 plants indicates that ABI5 regulates a subset of late embryogenesis-abundant genes during both developmental stages. Responsible for reducing cadmium uptake, mediated by interaction with MYB49 . Other Gene Models

The abi5-5 mutation was characterized at the molecular level and was shown to result from a two base pair deletion in the coding sequence of the ABI 5 gene. The wild type and mutant recombinant proteins were produced in E. coli and were assayed for DNA-binding activity on their target promoters by electrophoretic mobility shift assay (EMSA). the ABI5 gene by using a positional cloning approach and found that it encodes a member of the basic leucine zipper transcription factor family. The previously characterized abi5-1 allele encodes a protein that lacks the DNA binding and dimerization domains required for ABI5 function.

Abi5 gene

Its stability or degradation plays a central role in abscisic acid response. Sumoylated at Lys-391 by SIZ1. Sumoylation protects ABI5 from proteasome degradation, attenuating … WRKY40 facilitates the recruitment of JMJ17 to the ABI5 chromatin, which removes gene activation marks (H3K4me3) from the ABI5 chromatin, thereby repressing its expression. Additionally, WRKY40 represses the transcriptional activation activity of HY5, which can activate ABI5 expression by directly binding to its promoter.

ABI3, ABI5 and late embryogenesis genes are reactivated by ABA during a short development window. We show that ABI3 is required for the ABA-dependent growth arrest because it acts upstream of ABI5 and is essential for ABI5 gene expression. Using chromosomal immunoprecipitations (ChIP), we show that ABA increases the ABI5 occupancy

Promoter analysis revealed that an ABI5‐binding region is present next to the TATA box or initiator box. 2016-09-14 2021-03-06 2012-10-23 2020-10-03 ABI5, an ABA-insensitive gene, encodes a basic leucine zipper transcription factor.

(A) The sequence displayed corresponds to the reverse complement of nucleotides 33, 132 to 34,991 of … 2014-02-27 Figure 1. Isolation and expression of an ABI5-binding protein. (A) Deduced amino acid sequence encoded by the ABI five binding protein (AFP) gene.The putative nuclear localization motif is underlined. (B) Delineation of the AFP and ABI5 interaction domains (black boxes) by yeast two-hybrid experiments.(Left) ABI5 cDNA constructs fused to sequences encoding either GAL4 DNA binding or … the ABI5 gene by using a positional cloning approach and found that it encodes a member of the basic leucine zipper transcription factor family. The previously characterized abi5-1 allele encodes a protein that lacks the DNA binding and dimerization domains required for ABI5 function. Analyses of ABI5 expression provide evidence for ABA regulation, ABI5 gene (ABA insensitive 5) of Arabidopsis encodes a basic leucine zipper factor required for ABA response in the seed and vegetative tissues. Using transient gene expression in rice protoplasts, we provide evidence for the functional interactions of ABI5 with ABA signaling effectors VP1 (viviparous 1) and ABI1 (ABA insensitive 1).

ABI5 expression is autoregulated in transgenic plants and yeast ( Saccharomyces cerevisiae ), and stress response appears to involve ABI5-dependent and -independent mechanisms. To determine whether ABI5 is necessary and/or sufficient for ABA or stress response, we assayed the effects of increased ABI5 expression on growth and gene expression. 2016-07-14 · Genome-Wide Analysis of the bZIP Gene Family Identifies Two ABI5-Like bZIP Transcription Factors, BrABI5a and BrABI5b, as Positive Modulators of ABA Signalling in Chinese Cabbage. Yili Bai State Key Laboratory of Crop Stress Biology for Arid Areas, College of Life Science, Northwest A&F University, Yangling, Shaanxi, 712100, China. 2019-08-09 · Basic region/leucine zippers (bZIPs) are transcription factors (TFs) encoded by a large gene family in plants.

Interestingly, the ABI5 gene was also expressed in young seedlings, suggesting that ABI5 may have additional functions the ABI5 gene by using a positional cloning approach and found that it encodes a member of the basic leucine zipper transcription factor family. The previously characterized abi5-1 allele encodes a protein that lacks the DNA binding and dimerization domains required for ABI5 function. Analyses of ABI5 expression provide evidence for ABA regulation, WRKY40 facilitates the recruitment of JMJ17 to the ABI5 chromatin, which removes gene activation marks (H3K4me3) from the ABI5 chromatin, thereby repressing its expression.

NF-YC9 mediates abscisic acid (ABA) signaling via targeting to and aiding the ABA-responsive transcription factors such as ABI5. Comparison of seed and ABA-inducible vegetative gene expression in wild-type and abi5-1 plants indicates that ABI5 regulates a subset of late embryogenesis-abundant genes during both developmental stages. Responsible for reducing cadmium uptake, mediated by interaction with MYB49.

The gene corresponding to the ABI5 locus has been isolated independently by Finkelstein and Lynch (2000) and by Lopez‐Molina and Chua (2000) and encodes a basic leucine zipper transcription factor. The abi5–5 allele presents a two base pair deletion, resulting in a truncated ABI5 protein, lacking the basic and leucine zipper domains.

ABCB5 is a limbal stem cell gene required for corneal development and repair. Nature. 2014;511(7509):353-7. Kureshi AK, Dziasko M, Funderburgh JL, and

The ABA-responsive element binding protein/ABRE-binding factor and ABA INSENSITIVE 5 (AREB/ABF/ABI5) gene subfamily members, which belong to the basic domain/leucine zipper (bZIP) transcription factors family, participate in the ABA-mediated signaling pathway by regulating the expression of ABI5 expression is autoregulated in transgenic plants and yeast ( Saccharomyces cerevisiae ), and stress response appears to involve ABI5-dependent and -independent mechanisms. To determine whether ABI5 is necessary and/or sufficient for ABA or stress response, we assayed the effects of increased ABI5 expression on growth and gene expression. The various functions of these target genes indicate that ANAC060 has several functions.

(A) The sequence displayed corresponds to the reverse complement of nucleotides 33, 132 to 34,991 of BAC F2H17 (GenBank accession number AC006921.5). HRB2 enhances the light‐induced expression of a B‐box transcription factor gene, BBX21.
