Differential expression of poplar sucrose nonfermenting1-related protein kinase 2 genes in response to abiotic stress and abscisic acid
Examination of expression patterns of poplar genes encoding members of the sucrose nonfermenting1-related protein kinase 2 (SnRK2) family suggests that they are involved in abiotic stress responses, are at least partially activated by ABA, and show organ-specific responses.
Heterologous Overexpression of Poplar SnRK2 Genes Enhanced Salt Stress Tolerance in Arabidopsis thaliana
Poplar subclass 2 PtSnRK2 genes can modulate salt stress tolerance in Arabidopsis, through the activation of cellular signaling pathways in a different manner from that by herbal subclass 2 SnRK 2 genes.
Triple Loss of Function of Protein Phosphatases Type 2C Leads to Partial Constitutive Response to Endogenous Abscisic Acid1[C][W][OA]
Results indicate that ABA response is finely tuned by the integrated action of these genes, which is required to prevent a constitutive response to endogenous ABA that might have a deleterious effect on growth and development in the absence of environmental stress.
The Protein Kinase SnRK2.6 Mediates the Regulation of Sucrose Metabolism and Plant Growth in Arabidopsis[W][OA]
It is shown that SnRK2.6, previously identified as crucial in the control of stomatal aperture by abscisic acid (ABA), has a broad expression pattern and participates in the regulation of plant primary metabolism, and that this kinase confers ABA hypersensitivity during seedling growth.
Protein Phosphatases 2C Regulate the Activation of the Snf1-Related Kinase OST1 by Abscisic Acid in Arabidopsis[W]
Evidence that PP2Cs are directly implicated in the ABA-dependent activation of OST1 is provided and the activation mechanism of AMPK/Snf1-related kinases through the inhibition of regulating PP2C is conserved from plants to human.
The Regulatory Domain of SRK2E/OST1/SnRK2.6 Interacts with ABI1 and Integrates Abscisic Acid (ABA) and Osmotic Stress Signals Controlling Stomatal Closure in Arabidopsis*
It is suggested that the direct interaction between SRK2E/OST1 and ABI1 through Domain II plays a critical role in the control of stomatal closure.
Genetics and Phosphoproteomics Reveal a Protein Phosphorylation Network in the Abscisic Acid Signaling Pathway in Arabidopsis thaliana
A systems approach reveals how the SnRK2 family of kinases mediates abscisic acid signaling and identifies multiple components of the ABA-responsive protein phosphorylation network.
Physical interaction between SnRK2 and PP2C is conserved in Populus trichocarpa
It is suggested that physical interaction between SnRK2 and PP2C is also conserved in poplars and may be involved in the ABA signaling pathway in tree plants.
Identification of Open Stomata1-Interacting Proteins Reveals Interactions with Sucrose Non-fermenting1-Related Protein Kinases2 and with Type 2A Protein Phosphatases That Function in Abscisic Acid Responses1[OPEN]
Analysis of copurification and identification of OST1-interacting proteins after osmotic stress and ABA treatments suggested an interaction network between ABA-activated SnRK2-typeprotein kinases and several PP2A-type protein phosphatase regulatory subunits.
