Genetic and physiological evidence has demonstrated this key role of ABI5 in this process. Overexpression of ABI5 resulted in enhanced sensitivity to ABA treatment, and the abi5 mutant was insensitive to ABA treatment during both seed germination and vegetative growth (Finkelstein & Lynch, 2000; Lopez‐Molina et al., 2001; Tezuka et al., 2013).

2015-10-23 · GUS staining of ABI5 pro:ABI5-GUS seeds and seedlings was performed as previously described 31 using 50 mM potassium phosphate buffer (pH 7.0) containing 0.05% (v/v) Triton X-100, 1 mM K 3 Fe(CN We used abi5-4 lines expressing the 35S∷ABI5 transgene (abi5-4/35S∷ABI5) to investigate the relationship between protein accumulation and the extent of growth arrest in response to ABA. Fig. 5D shows that abi5-4/35S∷ABI5 transgenic lines expressing intermediate ABI5 levels also displayed an intermediate phenotype in the presence of ABA. The preservation of our genetic resources and production of high-quality seeds depends on their ability to remain viable and vigorous during storage. In a quantitative trait locus analysis on seed longevity in Medicago truncatula , we identified the bZIP transcription factor ABSCISIC ACID INSENSITIVE5 (ABI5). 2016-01-04 · The partial recovery of keg by abi5 indicated that KEG may have substrates other than ABI5 (Liu and Stone, 2010). In fact, KEG also interacts directly with ABF1 and ABF3, and mediates their ubiquitination and degradation by the proteasome (Chen et al., 2013). Similar to abi5, loss of ABF1 and ABF3 partially rescued the keg phenotype after ABA 2021-03-06 · Encodes a member of the basic leucine zipper transcription factor family, involved in ABA signalling during seed maturation and germination.

INTRODUCTION. The phytohormone abscisic acid is a major phytohormone that regulates plant growth and development, including seed dormancy, seed germination, seedling growth, and stomatal aperture, as well as plant responses to various abiotic and biotic stresses, such as drought, salt, and cold stresses and pathogen infection (Mauch-Mani and Mauch, 2005; Fujita et al., 2011; Hauser et al., 2011).

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.

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.

The COP9 signalosome (CSN) is a conserved heteromeric protein complex known to regulate the CULLIN-RING family of ubiquitin E3 ligases (CRLs), including the SCF sub-family of E3s [ 21 ]. Abscisic acid‐insensitive 5 (ABI5) is an essential and conserved plant basic leucine zipper transcription factor whose level controls seed germination and postgerminative development.

2021-03-06 · 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.

To overexpress FLC in the abi5-4 mutant background, plasmid p35S::GFP-FLC was transformed into abi5-4 plants. ABI5 functions upstream of miR156 to promote juvenile development by affecting the expression of genes in the miR156‐SPL pathway. Therefore, our study uncovers a new role of ABI5 in vegetative development in plants, and implies a role of ABA signaling in vegetative development in Arabidopsis.
