2019-03-01 · In turn, ABA promotes the binding of HY5 to ABI5, and transgenic plants overexpressing ABI5 display shorter hypocotyls, indicating that ABI5 enhances light responses. HY5 is a highly conserved central regulator of photo-morphogenesis [ 57 , 58 ] that acts downstream of phytochrome-A and UV RESISTANCE LOCUS8 photoreceptors [ 59 , 60 ].

ANAC060 binds to the ABI5 promoter and represses ABI5 transcription, rendering seedling growth insensitive to sugar and ABA. Abscisic acid‐insensitive 5 (ABI5) is an essential and conserved plant basic leucine zipper transcription factor whose level controls seed germination and postgerminative development. It has been demonstrated that activity of ABI5 is transcriptionally and post‐translationally regulated. 2014-02-27 2021-03-06 ABI5, COP1, HY5, light signalling, PHYTOCHROME INTERACTING FACTOR (PIF), seedling development.

This paper presents evidence that the SUMO E3 ligase SIZ1 negatively regulates abscisic acid (ABA) signaling, which is dependent on the bZIP transcripton factor ABI5. Loss-of-function T ABI5 is the best-studied key molecule in the ABA signaling pathway with respect to PTMs; therefore, this review could serve as a model to guide post-translational studies of important regulators ABI5 participates in ABA-regulated gene expression during seed development and subsequent vegetative stage by acting as the major mediator of ABA represssion of growth. It binds to the embryo specification element and the ABA-responsive element (ABRE) of the Dc3 gene promoter and to the ABRE of the Em1 and Em6 genes promoters. ABI5 is a positive regulator in the ABA signaling pathway. The abi5 mutant exhibits severe hyposensitivity to ABA and salt stress (Carles et al., 2002), and overexpression of ABI5 increases drought tolerance ability by reducing the rate of transpiration (Lopez-Molina et al., 2001). Arabidopsis, polyclonal, antibody, ABI5, ABA INSENSITIVE 5, GIA1, GROWTH-INSENSITIVITY TO ABA 1, Dc3 promoter-binding factor 1, AtDPBF1, GROWTH-INSENSITIVITY TO ABA 1, bZIP transcription factor 39, AtbZIP39 The basic Leucine zipper transcription factor ABSCISIC ACID INSENSITIVE5 (ABI5) is a key regulator of abscisic acid ([ABA][1])–mediated seed germination and postgermination seedling growth.

Physiological studies have shown that the ABI3 , ABI4 and ABI5 loci have similar qualitative effects on seed development and ABA sensitivity, consistent with action in a common pathway, but that null mutations in ABI3 are more severe than those in ABI4 or ABI5 (Finkelstein and Lynch, 2000; Finkelstein et al ., 1998; Parcy et al ., 1994).

Binds to the embryo specification element and the ABA-responsive element (ABRE) of the Dc3 gene promoter and to the ABRE of the Em1 and Em6 genes promoters. Can also trans-activate its own promoter, suggesting that it is autoregulated. 2014-11-01 Consistently, med16 and med25 mutants displayed opposite phenotypes in ABA response, cuticle permeability, and differential ABI5‐mediated EM1 and EM6 expression.

ABI5 protein levels are high in NO- 16 Dec 2016 In this review, we present the current understanding of the way ABI5 functions as (1) a regulator of abiotic stress responses and (2) an integrator 17 May 2019 Cannes Film Review: '5B'.

Therefore, our study uncovers a new role of ABI5 in vegetative development in plants, and implies a role of ABA signaling in vegetative development in Arabidopsis. 2016-11-01 The target genes of ABI5 enable further adaptations to abiotic stresses. In this review, we present the current understanding of the way ABI5 functions as (1) a regulator of abiotic stress responses and (2) an integrator of ABA crosstalk with other phytohormones. The results that are described primarily refer to In this study, we generated a genome‐wide DNA‐binding map of ANAC060, indicating that it directly binds to a G‐box motif. ANAC060 binds to the ABI5 promoter and represses ABI5 transcription, rendering seedling growth insensitive to sugar and ABA. Abscisic acid‐insensitive 5 (ABI5) is an essential and conserved plant basic leucine zipper transcription factor whose level controls seed germination and postgerminative development. It has been demonstrated that activity of ABI5 is transcriptionally and post‐translationally regulated.

In this study, we found that MdABI5, the apple homolog of Arabidopsis ABI5, positively regulated ABA-induced anthocyanin biosynthesis. Abstract 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. In turn, ABA promotes the binding of HY5 to ABI5, and transgenic plants overexpressing ABI5 display shorter hypocotyls, indicating that ABI5 enhances light responses.

The abi5 mutant (SALK_013163; Zheng et al., 2012) was obtained from the ABRC, and the T‐DNA insertion is approximately 1 kb upstream of the ABI5 transcription start site. qRT‐PCR analyses showed that the transcription levels of ABI5 and RAV1 were markedly decreased in the RAV1‐U abi5 double mutant (Figure S6).

Conversely, DET1 stabilises the PIF proteins primarily in the dark, which might enhance ABI5 expression (Dong et al The transcription factor ABSCISIC ACID INSENSITIVE5 (ABI5) of the abscisic acid (ABA) signaling pathway plays a central role in the inhibition of seed germination. ABI5 is precisely regulated by the core ABA signaling components and multiple other factors.

(A) Genotyping and (B) expression analysis of PPC1, PPC2, and 2 Feb 2021 Drought stress analysis of MAP kinase mutants and transgenic plants suggested that except phosphor-null ABI5, all other mutants showed such as ABA-Insensitive5 (ABI5) and ABA-responsive element.

ABI5 functions in the core ABA signaling, which is composed of PYR/PYL/RCAR receptors, PP2C phosp … 2019-03-01 2021-03-22 Genetic and physiological evidence has demonstrated this key role of ABI5 in this process. Overexpression of ABI5 resulted in enhanced sensitivity to ABA treatment, and the abi5 mutant was insensitive to ABA treatment during both seed germination and vegetative growth (Finkelstein & Lynch, 2000; Lopez‐Molina et al., 2001; Tezuka et al., 2013). 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. 2014-06-18 2018-02-20 2021-01-26 2020-03-24 Highlights. The high integration of light and ABA signaling promotes the flavonol biosynthesis. ABA-induced flavonol biosynthesis involves HY5, ABI5, and PFG genes.
