ABA inhibited germination of isolated embryos which, otherwise, germinated rapidly in water (100 % germination between 24 and 36 h; Fig. S4 in Supplementary Data), thus providing extreme responses and also the possibility of evaluating the effect of the seed coats, if any, on the regulation of ABI5 levels by ABA. ABI5 protein was detected in

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 . Chromosome : 2: Locus

A K391R substitution in ABI5 ABI5 is a basic leucine zipper (bZIP) TF that plays a crucial role in ABA signaling-mediated seed germination, chlorophyll catabolism, leaf senescence, and abiotic stress adaptation (Kanai et al., 2010; Sakuraba et al., 2014; Skubacz et al., 2016; Zhao et al., 2020). 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. ABI5 functions in the core ABA signaling, which is composed of PYR/PYL/RCAR receptors, PP2C phosphatases and SnRK2 kinases, through the regulation The Arabidopsis abscisic acid response gene ABI5 encodes a basic leucine zipper transcription factor.

Components of auxin, cytokinin, gibberellic acid, jasmonate and brassinosteroid signaling and metabolism pathways were shown to take part in ABI5 regulation and/or to be regulated by ABI5. Monocot orthologs of AtABI5 have been identified. In addition, in the presence of exogenous ABA, the abi5 pho1 double mutant, similar to the pho1-2 mutant, showed significantly slower and the abi5 mutant displayed increased germination rates compared with wild-type plants . These results demonstrate that PHO1 is epistatic to ABI5 in ABA-mediated seed germination and early seedling development.

Correspondingly, the seed germination from two independent gim1 ABI5‐5 hybrid lines, gim1 ABI5‐5(A) and gim1 ABI5‐5(E), showed hypersensitivity to ABA . In contrast, the gim1 abi5‐4 double mutant showed a similar germination phenotype in comparison with its parental gim1 and abi5‐4 mutants .

ABA negatively mediates seed size by inﬂuencing the timing of endosperm cellularization. Furthermore, we demonstrated that the ABA signaling component ABI5 directly binds to the pro-moter region of SHB1 during early seed development. Our re-sults thus showed that ABA regulates early seed development by ABI5-regulated SHB1 expression. RESULTS

of ABI5 protein, whereas afp1 mutants were hypersensitive to ABA and had increased ABI5 accumulation (Lopez-Molina et al. 2003). Most of these measurements compared seedlings that had already germinated with seeds whose germination was inhibited, such that they did not distin-guish between reduced ABI5 levels as a cause or efect of germination. These results indicate that ABI5 acts downstream of ABI3 to reactivate late embryogenesis programmes and to arrest growth of germinating embryos. Although ABI5 is consistently located in the nucleus, chromosomal immunoprecipitation (ChIP) experiments revealed that ABA increases ABI5 occupancy on the AtEm6 promoter. 2001-04-10 ABI5 Encodes a Basic Leucine Zipper Transcription Factor Ruth R.

In abi5–4 plants, ABI5(K391R ) expression caused greater ABA hypersensitivity (gene expression, seed germination arrest and primary root growth inhibition) compared with ABI5 expression. Together, these results establish that SIZ1-dependent sumoylation of ABI5 attenuates ABA signaling. Abscisic acid (ABA) regulates plant development and is crucial for plant responses to biotic and abiotic stresses.

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.
