In this review, we present the current understanding of the way ABI5 functions as (1) a regulator of abiotic stress responses and (2) an integrator of ABA crosstalk with other phytohormones. The results that are described primarily refer to In this study, we generated a genome‐wide DNA‐binding map of ANAC060, indicating that it directly binds to a G‐box motif. ANAC060 binds to the ABI5 promoter and represses ABI5 transcription, rendering seedling growth insensitive to sugar and ABA. 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. 2014-02-27 2021-03-06 ABI5, COP1, HY5, light signalling, PHYTOCHROME INTERACTING FACTOR (PIF), seedling development.

The abi5 mutant exhibits severe hyposensitivity to ABA and salt stress (Carles et al., 2002), and overexpression of ABI5 increases drought tolerance ability by reducing the rate of transpiration (Lopez-Molina et al., 2001).

While a family of SUCROSE NONFERMENTING1-related protein kinase2s (SnRK2s) is responsible for [ABA][1]-induced phosphorylation and stabilization of ABI5, the phosphatase(s) responsible for 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.

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. These results Seed germination and subsequent seedling establishment are important developmental processes that undergo extremely complex changes of physiological status and are precisely regulated at transcriptional and translational levels.

In addition, it negatively regulates ABI5 expression by inducing the degradation of HY5 during germination (Fernando & Schroeder, 2015).

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. 2015-09-01 · ABI5 is the best-studied key molecule in the ABA signaling pathway with respect to PTMs; therefore, this review could serve as a model to guide post-translational studies of important regulators in other plant hormone signaling pathways. ABI5 is the best-studied key molecule in the ABA signaling pathway with respect to PTMs; therefore, this review could serve as a model to guide post-translational studies of important regulators in other plant hormone signaling pathways. Keywords: (de-)phosphorylation; ABA signaling; ABI5; sumoylation; ubiquitination. As a crucial regulator of ABA signaling, ABSCISIC ACID-INSENSITIVE5 (ABI5) is involved in many aspects of plant growth and development, yet its regulation of anthocyanin biosynthesis has not been elucidated.

Ryu et al.show that ABA regulator genes are suppressed by a complex containing It had previously been shown that these abi4 and abi5 mutants are not resistant to the extremely high C/low N stress condition (300mM G/0.1mM N) used in cni mutant screening (Sato et al., 2009). The detailed C/N responses of these mutant to relatively milder high C/low N stress conditions (200mM Glc/0.3mM N) was therefore re-examined and the ratio of green-coloured cotyledons was quantified.
