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. However, the complex regulatory network of ABI5 remains largely unknown.

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.

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 ]. Our results show that ABI5 plays a key role in seedling growth under photorespiratory conditions by regulating photorespiratory enzyme expression, and ABA regulates plant growth under low CO 2 conditions through modulating ABI5 expression. abi5-1 seedlings grown at low CO 2 showed lower F v /F m values (Fig. 6C, D). Genetic and physiological evidence has demonstrated this key role of ABI5 in this process.

Transgenic plants of ABI5-5, ABI5 S42A, ABI5 S145A, and ABI5 S42AS145AT201A were generated by Agrobacterium tumefaciens GV3101-mediated floral infiltration (Clough and Bent, 1998). To overexpress FLC in the abi5-4 mutant background, plasmid p35S::GFP-FLC was transformed into abi5-4 plants.

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 ]. In this review, we summarized the latest advancement on the function of PTMs involved in the regulation of seed germination, in which the PTMs for ABI5- and DELLA-containing proteins play the key roles. Meanwhile, the studies on PTM-based proteomics during seed germination and the crosstalk of different PTMs are also discussed.

2016-04-14 · Background Being sessile organisms, plants are often exposed to a wide array of abiotic and biotic stresses. Abiotic stress conditions include drought, heat, cold and salinity, whereas biotic stress arises mainly from bacteria, fungi, viruses, nematodes and insects. To adapt to such adverse situations, plants have evolved well-developed mechanisms that help to perceive the stress signal and

The ABI5 subgroup consists 47of ABA INSENSITIVE 5 (ABI5, also referred to as Dc3 PROTEIN BINDING FACTOR or DPBF1) and three other DPBFs48 (DBPF2, DPBF3/AREB3 for ABA RESPONSIVE ELEMENT BINDING, available under aCC-BY-NC-ND 4.0 International license. degradation of PYLs, resulting in the suppression of ABI5 expression (Irigoyen et al., 2014). In addition, it negatively regulates ABI5 expression by inducing the degradation of HY5 during germination (Fernando & Schroeder, 2015). 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. However, the complex regulatory network of ABI5 remains largely unknown. The expression of ABI5 is upregulated by ABI3, and ABI3 itself can also directly regulate the expression of key negative regulators involved in the seed-to-seedling transition 42.

Consistently, med16 and med25 mutants displayed opposite phenotypes in ABA response, cuticle permeability, and differential ABI5‐mediated EM1 and EM6 expression. To functionally analyze the involvement of BIN2 phosphorylation sites in ABI5 activity, we fused the mutant protein ABI5 S41A T35A S36A with HA tag, designated as the HA-ABI5 mutant, and introduced the mutant protein into the abi5-1 background under its native promoter (abi5-1/HA-ABI5 mutant).

Hasegawaa,1 ABI5 Our initial mapping of ABI5 localized it to the lower arm of chromosome 2, near the phenotypic marker pyrimidine-requiring (py) (Finkelstein, 1994). To generate fine-mapping populations with closely linked recombinations, we out-crossed abi5-1 and abi5-3 (in the Wassilewskija and Colum-bia [Col] backgrounds, respectively) to lines carrying ABI5 expression is greatly reduced in abi3‐1 mutants, which has low AtEm1 or AtEm6 expression.

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. Together, our data indicate that MED16 and MED25 differentially regulate ABA signaling by antagonistically affecting ABI5‐mediated transcription in Arabidopsis.

2018-02-20 · ABI5 has been implicated as the final inhibitor of seed germination, possibly acting downstream of the GA repressor RGL2 [ 16, 17 ]. The COP9 signalosome (CSN) is a conserved heteromeric protein complex known to regulate the CULLIN-RING family of ubiquitin E3 ligases (CRLs), including the SCF sub-family of E3s [ 21 ]. 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. Transgenic plants of ABI5-5, ABI5 S42A, ABI5 S145A, and ABI5 S42AS145AT201A were generated by Agrobacterium tumefaciens GV3101-mediated floral infiltration (Clough and Bent, 1998). To overexpress FLC in the abi5-4 mutant background, plasmid p35S::GFP-FLC was transformed into abi5-4 plants. ABI5 functions upstream of miR156 to promote juvenile development by affecting the expression of genes in the miR156‐SPL pathway.
