AFP2 nuclear localization is stress dependent. 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. The Mt -ABI5 gene, a bZIP transcription factor and the homolog of Arabidopsis ABI5 (Wang et al., 2015), was located at position 64.9 on LG 7, within the confidence interval of three QTL for longevity both for moderate and accelerated aging with seeds obtained from two different growth locations (Angers and Dijon) (Figure 1C, Table 1). Abscisic acid (ABA) and stress response from late embryonic growth through early seedling development is regulated by a signaling network that includes the Arabidopsis ABA-insensitive (ABI)5 gene, which encodes a basic leucine zipper transcription factor.

Abi5 gene

The first 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). We isolated 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. Characterization of abi5 Mutant Seeds of Pea. (A) Gene structure of Ps-ABI5 and confirmed Ps-abi5 EMS mutants detected by TILLING screening.

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). 2009-07-28 2016-07-14 2014-02-27 2016-12-20 The Arabidopsis abscisic acid response gene ABI5 encodes a basic leucine zipper transcription factor. The Arabidopsis abscisic acid (ABA)-insensitive abi5 mutants have pleiotropic defects in ABA response, including decreased sensitivity to ABA inhibition of germination and altered expression of some ABA-regulated genes.

Arabidopsis mutants abi3, abi5 and abi4 exhibit ABA-resistant germination. 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 2008-01-31 · ABI5 and its homologs physically interact with other ABA-responsive transcription activators, ABI3 or its orthologs, to regulate seed-specific and/or ABA-inducible gene expression (Lopez-Molina et al.

Analyses of ABI5 expression provide evidence for ABA regulation, cross-regulation by other ABI genes, and possibly autoregulation. 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. 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.

(a) Neighbor-joining tree of potato and Arabidopsis AREB/ABF/ABI5 proteins and the gene structure of each potato ABI5 is a gene directly induced to be expressed by ABI3 gene. Since a germination repressing effect of ABI3 is known as a phenomenon occurring by inducing the expression of ABI5, to check if the delay of flowering by ABI3 are caused by an increase in expression of ABI5, the case of overexpressing ABI5 … The Arabidopsis abscisic acid response gene ABI5 encodes a basic leucine zipper transcription factor. The Arabidopsis abscisic acid (ABA)-insensitive abi5 mutants have pleiotropic defects in ABA response, including decreased sensitivity to ABA inhibition of germination and altered expression of some ABA-regulated genes.

Responsible for reducing cadmium uptake, mediated by interaction with MYB49 . … 2020-10-03 Abscisic Acid-Insensitive 5 ( ABI5) is one of the 13 members of group A and is involved in ABA signalling during seed maturation, and germination [4]. Comparison of expression of eight ABI5-homologous genes shows overlapping regulation by ABI3, ABI4, and ABI5, suggestive of a combinatorial network involving positive and negative regulatory of AFP-mediated repression of gene expression. Chemical inhibition of histone deacetylase activity by trichostatin A suppressed AFP efects on a small fraction of the ABI5-regulated genes tested. Collectively, these results suggest that the AFPs participate in multiple mechanisms modulat-ing ABA response, including both TOPLESS-dependent Gene Symbol Synonym.

AFP2 nuclear localization is stress dependent. By contrast, ABI5 regulates the expression of PYL11 and PYL12 by directly binding to their promoters. Moreover, the expression of eight other PYL s is also affected during the germination of abi5 mutants. Promoter analysis revealed that an ABI5‐binding region is present next to the TATA box or initiator box. ABI5, an ABA-insensitive gene, encodes a basic leucine zipper transcription factor. Expres- sion of ABI5 defines a narrow developmental checkpoint following germination, during which Arabidopsis plants sense the water status in the environment.
