An abi4-1 mutant line in a Col-0 background and an abi5-1 mutant line in a Ws background were obtained from Dr. Dapeng Zhang. We generated the double mutant (abi4abi5) by crossing the single mutants. 2.2. Transgenic plant generation TheABI4-1345to0andABI5-1097to0promotersequenceswere Therefore, the expression of ABI5, MYB30 and their target genes were evaluated in asp1 and wild‐type seedlings. Expression of ABI5 and ABI5‐target genes, RD29A, RD29B, RAB18, Em6, and ADH1, were induced by exogenous ABA treatment, but the induction was less abundant in asp1 than in wild‐type seedlings (Figure 3A).

Encodes a member of the basic leucine zipper transcription factor family, involved in ABA signalling during seed maturation and germination. 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. ABI5 Our initial mapping of ABI5 localized it to the lower arm of chromosome 2, near the phenotypic marker pyrimidine-requiring (py) (Finkelstein, 1994).

ABI5-BINDING PROTEIN2 (AFP2) negatively regulates the abscisic acid signal by accelerating ABI5 degradation during seed germination in Arabidopsis (Arabidopsis thaliana). The abscisic acid signal is reported to delay flowering by up-regulating Flowering Locus C expression, but the role of AFP2 in regulating flowering time is unknown.

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. 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 .

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 key component in ABA-triggered pathways during germination, seedling establishment, and vegetative growth (Lopez-Molina et al., 2001); in addition, it has been reported to play certain roles in nitrogen assimilation and signaling (Signora et al., 2001). Abstract ABI5-BINDING PROTEIN2 (AFP2) negatively regulates the abscisic acid signal by accelerating ABI5 degradation during seed germination in Arabidopsis (Arabidopsis thaliana). The abscisic acid signal is reported to delay flowering by up-regulating Flowering Locus C expression, but the role of AFP2 in regulating flowering time is unknown. The triple mutant had greatly reduced phosphorylation activity in in-gel kinase experiments using basic leucine zipper (bZIP) transcription factors including ABI5. Microarray experiments revealed that 48 and 30% of the down-regulated genes in abi5 and abi3 seeds were suppressed in the triple mutant seeds, respectively.
