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 accumulated ABI5 protein further shows heteromeric interaction with HY5, and thus synergistically activates its own expression. Our findings reveal a novel transcriptional switch, composed of JMJ17–WRKY40 and HY5–ABI5 modules, which regulates the ABA response during seed germination and seedling development in Arabidopsis. 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 . … Ubiquitinated. AFP1, KEG and RPN10 mediate its proteasome-dependent degradation.

2020-03-02 · Consistently, PIFs and the G-box motifs in the ABI5 promoter determine ABI5 expression in darkness, and overexpression of ABI5 could rescue the ABA-insensitive phenotypes of pifq mutants in the dark. Moreover, we discovered that PIFs can physically interact with the ABA receptors PYL8 and PYL9, and that this interaction is not regulated by ABA. The accumulated ABI5 protein further shows heteromeric interaction with HY5, and thus synergistically activates its own expression. Our findings reveal a novel transcriptional switch, composed of JMJ17–WRKY40 and HY5–ABI5 modules, which regulates the ABA response during seed germination and seedling development in Arabidopsis. ABI5 was previously reported as the target protein of AFP2 during seed germination (Lopez-Molina et al., 2003), and overexpression of ABI5 activates the flowering negative factor FLC at the transcriptional level to repress flowering (Wang et al., 2013b).

ABI5 bryts även ned proteolytiskt av RING-fingerprotein Håller på väg, vilket säkerställer en låg nivå av ABI5-produktion i frånvaro av ABA 28, 29 .

These findings demonstrate that PPC2 plays an important role in the acclimation of Arabidopsis plants to low CO2 availability by linking photorespiratory metabolism to primary metabolism, and that this is mediated, at least in part, through ABA and 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). ABI5-BINDING PROTEIN2 (AFP2) negatively regulates the abscisic acid signal by accelerating ABI5 degradation during seed germination in Arabidopsis (Arabidopsis thaliana).

Seven other members of this group are expressed during seed maturation,but only one of them (Enhanced Em Level 2015-10-23 · ABI5 and ABI5C153S were cloned in the pEarleyGate 203 vector38 using the GATEWAY technology and the following primers (ABI5-F 5′-ATGGTAACTAGAGAAACGAAGTTGACG-3′; ABI5-R 5′-TTAGAGTGGACAACTCGGG-3′).

This suggests that nucleo‐cytoplasmic shuttling may not be a major regulatory step in ABI5 activity.

Sumoylated at Lys-391 by SIZ1. Sumoylation protects ABI5 from proteasome degradation, attenuating … 2001-04-10 ABA INSENSITIVE 5 (ABI5) is a basic leucine zipper (bZIP) transcription factor which acts in the abscisic acid (ABA) network and is activated in response to abiotic stresses. However, the precise role of barley (Hordeum vulgare) ABI5 in ABA signaling and its function under stress remains elusive. Here, we show that HvABI5 is involved in ABA-dependent regulation of barley response to drought 2000-04-01 Using an ABI5::GUS fusion gene under the control of ABI5 promoter sequences, we have shown that ABI5 is constitutively localized in the nucleus in the presence or absence of ABA .

ABI5 was previously reported as the target protein of AFP2 during seed germination (Lopez-Molina et al., 2003), and overexpression of ABI5 activates the flowering negative factor FLC at the transcriptional level to repress flowering (Wang et al., 2013b). Thus, we compared the transcription of FLC in Col, afp2, and AFP2-ox under LD conditions.

In the presence of abscisic acid, XIW1 accumulates in the nucleus, where it interacts with ABI5 and promotes ABI5 stability and ABA responses. Get in touch with . (@ABI5) — 56 answers, 255 likes.
