SOS3 (salt overly sensitive 3) from Arabidopsis thaliana: expression, purification, crystallization and preliminary X-ray analysis.
The salt-tolerance gene SOS3 (salt overly sensitive 3) of Arabidopsis thaliana encodes a calcium-binding protein that is able to sense the cytosolic calcium signal elicited by salt stress. SOS3 activates the SOS2 protein kinase, which activates various ion transporters. SOS3 was cloned into a plasmid and expressed in Escherichia coli, allowing purification of the protein to homogeneity. Two cry...
متن کاملA novel domain in the protein kinase SOS2 mediates interaction with the protein phosphatase 2C ABI2.
SOS2 (salt overly sensitive 2) is a serine/threonine protein kinase required for salt tolerance in Arabidopsis thaliana. In this study, we identified the protein phosphatase 2C ABI2 (abscisic acid-insensitive 2) as a SOS2-interacting protein. Deletion analysis led to the discovery of a novel protein domain of 37 amino acid residues, designated as the protein phosphatase interaction (PPI) motif,...
متن کاملGenome-wide analysis of light-dependent transcript accumulation patterns during early stages of Arabidopsis seedling deetiolation.
Light is among the most important exogenous factors that regulate plant development. To sense light quality, intensity, direction, and duration, plants have evolved multiple photoreceptors that enable the detection of photons from the ultraviolet B (UV-B) to the far-red spectrum. To study the effect of different light qualities on early gene expression, dark-grown Arabidopsis (Arabidopsis thali...
متن کاملThe SOS3 family of calcium sensors and SOS2 family of protein kinases in Arabidopsis.
During the course of its lifecycle, a plant may experience extremes of temperature and moisture, excesses and deficiencies of minerals, and challenges from herbivores and pathogens, all of which provide specific signals for altered plant growth and development. Ca has been widely implicated as an intracellular messenger of physiologically and environmentally induced signaling pathways in plants...
متن کاملSCABP8/CBL10, a putative calcium sensor, interacts with the protein kinase SOS2 to protect Arabidopsis shoots from salt stress.
The SOS (for Salt Overly Sensitive) pathway plays essential roles in conferring salt tolerance in Arabidopsis thaliana. Under salt stress, the calcium sensor SOS3 activates the kinase SOS2 that positively regulates SOS1, a plasma membrane sodium/proton antiporter. We show that SOS3 acts primarily in roots under salt stress. By contrast, the SOS3 homolog SOS3-LIKE CALCIUM BINDING PROTEIN8 (SCABP...
