Gene : ABI3 A. thaliana

Gene ID  ? AT3G24650
Brief Description  AP2/B3-like transcriptional factor family protein  Source: Araport11 (06/2016).
Is Obsolete?  false
Computational Description  ? ABA INSENSITIVE 3 (ABI3); CONTAINS InterPro DOMAIN/s: Transcriptional factor B3 (InterPro:IPR003340); BEST Arabidopsis thaliana protein match is: AP2/B3-like transcriptional factor family protein (TAIR:AT3G26790.1).  Source: TAIR, Jun 30, 2015.
Curator Summary  ? Homologous to the maize transcription factor Viviparous-1. Full length ABI3 protein binds to the highly conserved RY motif [DNA motif CATGCA(TG)], present in many seed-specific promoters, and the B3 domains of this transcription factor is necessary for the specific interaction with the RY element. Transcriptional activity of ABI3 requires the B3 DNA-binding domain and an activation domain. In addition to the known N-terminal-located activation domain, a second transcription activation domain was found in the B1 region of ABI3. ABI3 is essential for seed maturation. Regulator of the transition between embryo maturation and early seedling development. Putative seed-specific transcriptional activator. ABI3 is a central regulator in ABA signaling and is unstable in vivo. It interacts with and can by polyubiquitinated by AIP2 in vivo. Based on double mutant analyses, ABI3 interacts genetically with both FUS3 and LEC1 and is involved in controlling accumulation of chlorophyll and anthocyanins, sensitivity to abscisic acid, and expression of the members of the 12S storage protein gene family. In addition, both FUS3 and LEC1 regulate positively the abundance of the ABI3 protein in the seed. Alternative splicing of ABI3 is developmentally regulated by SUA (AT3G54230).  Source: TAIR, Jun 30, 2015.

We suggest that LEC1 controls the expression of the SSP genes in a hierarchical manner, which involves ABI3 and FUS3. 15695450
Double-mutant analysis showed that ABA-insensitive 4 (ABI4) is epistatic to AtLPP2 but ABA-insensitive 3 (ABI3) is not. 15960620
The expression of ABI3- and/or ABA-responsive genes and cis-elements in the promoters are discussed 16463099
ABI3 expression ceases following the completion of germination in both tomato and Arabidopsis seeds, suggesting that expression of this gene does not regulate germination. 16531465
ABSCISIC ACID-INSENSITIVE3 (ABI3) regulates the developmental expression of HsfA9. 17220197
PRT6 control of germination and establishment, as exemplified by ABA and sugar sensitivity, as well as storage oil mobilization, occurs at least in part via transcription factors ABI3 and ABI5. 19255443
We show that repression of germination by far-red light involves stabilized DELLA factors GAI, RGA and RGL2 that stimulate endogenous abscisic acid synthesis which, in turn, blocks germination through the transcription factor ABI3. 19556968
ABI3 and PIL5 collaboratively activate the expression of SOM mRNA by directly binding to and interacting with each other at the SOM promoter. 21467583
N-acylethanolamines may act to inhibit early seedling establishment by both ABI3-dependent and ABI3-independent pathways. 21633189

Auxin controls seed dormancy through stimulation of abscisic acid signaling by inducing ARF-mediated ABI3 activation in Arabidopsis. 23986496
ABI3 controls embryo degreening through Mendel's I locus. 24043799
The function of AtSAG in abscisic acid (ABA)signalling depended on ABI3 and ABI5. AtSAG is an important negative regulator of ABA signalling during seed germination and seedling development. 24163287
The BES1-TPL-HDA19 repressor complex controls epigenetic silencing of ABI3 and thereby suppresses the abscisic acid signalling output during early seedling development. 24938150
WRKY41 is an important regulator of ABI3 expression, and hence of seed dormancy. 24946881
RAV1 plays an important role in abscisic acid signaling by modulating the expression of ABI3, ABI4, and AbI5 during seed germination and early seedling development. 25231920
This study examined the role of ABSCISIC ACID INSENSITIVE3 (ABI3), FUSCA3 (FUS3) and LEAFY COTYLEDON2 (LEC2), in the production of seed reserves in Arabidopsis. 25840088
TIP3;1 and TIP3;2 promoters could be activated by ABI3 in the presence of abscisic acid (ABA) in Arabidopsis protoplasts. TIP3 proteins were detected in protoplasts transiently expressing ABI3 and in ABI3-overexpressing seedlings treated with ABA. 26019256
AIP1 interacts with ABAP1, with a plant histone modification "reader" (LHP1) and with non modified histones. Also, expression of ABAP1 and LHP1 target genes were repressed in flower buds of plants with reduced levels of AIP1. 26538092
