2019-12-02 · Among these, genes classified in group I (61.6% of the 1198 upregulated genes) showed lower expression levels in xiw1-1 and abi5-8 than in Col-0. This group includes a large number of ABA signaling genes, e.g., SnRK2 . 2 , SnRK2 . 6 , and ABRE2 / ABF2 , as well as ABA-responsive genes, e.g., RD29A , RD29B , and RAB18 ( Figure 4 E and Supplemental Data 2 ).

genes by abi5-9 (Fig. 3A). The full-length ABI3 fused to Gal4-BD showed strong autoactivation of the reporter genes (data not shown), as previously reported;41 therefore, trun-cated ABI3 proteins were fused to Gal4-BD and used to evaluate the interaction with abi5-9 and ABI5 (Fig. 3B). As shown previously,27 ABI5 interacted with truncated ABI3

In addition, HY5 binding to the ABI5 promoter is enhanced by ABA treatment, and overexpression of ABI5 restores ABA sensitivity in hy5 mutants and leads to enhanced light responses in the wild type plants [33] . Here, we found that the change in ABI5 expression had effects on these gene expressions, especially in abi5-1 seeds. When treated by 5 mM 3-AT, EM1 and EM6, which functions in promoting seed germination, were dominantly down-regulated in Col-0, which could partly explain the inhibition of 3-AT on seed germination of Col-0. ABI3, ABI5 and late embryogenesis genes are reactivated by ABA during a short development window. We show that ABI3 is required for the ABA-dependent growth arrest because it acts upstream of ABI5 and is essential for ABI5 gene expression. Using chromosomal immunoprecipitations (ChIP), we show that ABA increases the ABI5 occupancy In each of the tested genes, histone acetylation was detected in a single specific region of chromatin within 1-kb upstream of the translation initiation codon, and overexpression of OTLD1 reduced these amounts of H3 acetylation by 1.5- to 3-fold in ARL, GA20OX2, and OSR2 , whereas H3 acetylation in WUS and in ABI5 was reduced by up to 80- and 5-fold, respectively, relative to the wild-type ABI5 is a gene directly induced to be expressed by ABI3 gene. Since a germination repressing effect of ABI3 is known as a phenomenon occurring by inducing the expression of ABI5, to check if the delay of flowering by ABI3 are caused by an increase in expression of ABI5, the case of overexpressing ABI5 was also checked.

ABA-insensitive 5 protein (ABI5) binds to the embryonic specification element (ESE) of the Dc3 gene promoter and ABA response element (ABRE). By controlling the expression of ABA regulatory genes during seed development, it directly affects ABA synthesis .

2 , SnRK2 . 6 , and ABRE2 / ABF2 , as well as ABA-responsive genes, e.g., RD29A , RD29B , and RAB18 ( Figure 4 E and Supplemental Data 2 ). The gene corresponding to the ABI5 locus has been isolated independently by Finkelstein and Lynch (2000) and by Lopez‐Molina and Chua (2000) and encodes a basic leucine zipper transcription factor.

These genes were found on 5 out of 12 chromosomes. StAREB1, StAREB2, StABI5, and StAREB4 were localized on chromosome 1, 4, 9, and 11, respectively. Chromosome 10 contained three loci, including StAREB3, StABL1, and StABL2 (Figure1b). Table 1. General information for potato AREB/ABF/ABI5 genes. Gene Gene ID CDS AA MW PI Predicted Subcellular

Mutation in either HRB2 or BBX21 led to reduced water loss and ABA hypersensitivity. 2014-02-27 · Interestingly, a recent study showed that HY5 directly binds to the promoter of ABI5 and is required for the expression of ABI5 and ABI5-targeted genes . In addition, HY5 binding to the ABI5 promoter is enhanced by ABA treatment, and overexpression of ABI5 restores ABA sensitivity in hy5 mutants and leads to enhanced light responses in the wild type plants [33] . Here, we found that the change in ABI5 expression had effects on these gene expressions, especially in abi5-1 seeds.

ABI5 expression is autoregulated in transgenic plants and yeast ( Saccharomyces cerevisiae ), and stress response appears to involve ABI5-dependent and -independent mechanisms. To determine whether ABI5 is necessary and/or sufficient for ABA or stress response, we assayed the effects of increased ABI5 expression on growth and gene expression.

Displaying 1 - 25. To see ESTs associated with your gene of interest, click on the Locus link. ABI4 and HY5 antagonistically regulate the expression of CONSTITUTIVE PHOTOMORPHOGENIC1 (COP1) and the subsequent greening process. In turn, ABI4 and HY5 are targeted for degradation by COP1 in the light and dark, respectively, to ensure a proper interplay of ABI4 and HY5 actions during seedling de-etiolation. ABA-insensitive 5 protein (ABI5) binds to the embryonic specification element (ESE) of the Dc3 gene promoter and ABA response element (ABRE). By controlling the expression of ABA regulatory genes during seed development, it directly affects ABA synthesis .
