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. ABI5 is a rate- limiting factor conferring ABA-mediated postgermination developmental growth arrest.

HRB2 enhances the light‐induced expression of a B‐box transcription factor gene, BBX21. BBX21 binds a T/G box in the ABI5 promoter and recruits HRB2 to modulate the chromatin structure at the ABI5 locus. Mutation in either HRB2 or BBX21 led to reduced water loss and ABA hypersensitivity.

Involved in abscisic acid (ABA) signaling pathway. Binds to the G-box motif 5'-CACGTG-3' of TRAB1 gene promoter (PubMed: 17604002 ). Involved in the regulation of pollen maturation. 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.

Abi5 gene

However, ABI5 action was not necessary for vegetative ABA responses such as stomatal regulation. 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. Analyses of ABI5 expression provide evidence for ABA regulation, As a crucial regulator of ABA signaling, ABSCISIC ACID-INSENSITIVE5 (ABI5) is involved in many aspects of plant growth and development, yet its regulation of anthocyanin biosynthesis has not been elucidated. In this study, we found that MdABI5, the apple homolog of Arabidopsis ABI5, positively regulated ABA-induced anthocyanin biosynthesis.

(6–8). ABI5 regulates the expression of ABA induced, mostly seed-specific, AtEM genes that encode class I late embryogen-esis-abundant (LEA) proteins important for seed maturation (6, 9, 10). Interestingly, the ABI5 gene was also expressed in young seedlings, suggesting that ABI5 may have additional functions

RNA-sequencing Using transient gene expression in rice protoplasts, we provide evidence for the functional interactions of ABI5 with ABA signaling effectors VP1 (viviparous 1) and The transcription factor. ABI5 is one of these. It regulates gene expression during embryogenesis and in response to ABA. An ABA-insensitive mutant, abi5-6, 9 Aug 2019 Background.

Kureshi AK, Dziasko M, Funderburgh JL, and 8 Nov 2020 At baseline, approximately 80% of patients had high interferon gene signature and the average swollen and tender joint counts were around 8 Using transient gene expression in rice protoplasts, we provide evidence for the functional interactions of ABI5 with ABA signaling effectors VP1 (viviparous 1) and 22 Apr 2017 gene, AGL67, may act as a repressor of seed germination, its some downstream ABA signaling pathway genes, such as ABI5,.

The Arabidopsis abscisic acid (ABA)-insensitive abi5 mutants have pleiotropic defects in ABA response, including decreased sensitivity to ABA inhibition of germination … 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 .

… 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.
