(2002, background): “The remaining 25 comprise the SNF1related kinase 3 subgroup, members of which appear to interact with a diverse collection of calcineurin B-like sensor relays and to play a role in a number of signaling processes, including those related to salt tolerance (Halfter et al., 2000; Luan et al., 2002).”

A genomics approach towards salt stress tolerance (2001, background): “stress tolerance have appeared in a number of stress signal recognition and transduction components and in additional downstream reactions, such as functions in sodium partitioning [3, 15, 17, 19, 23, 33, 42, 43] but additional components can be expected.”
Mechanisms of Plant Responses and Adaptation to Soil Salinity (2020, background): “87,88 A recent report indicated that PKS5 inhibits the activity of SOS2 by promoting interaction between SOS2 and 14-3-3 proteins; the salt stressinduced Ca2+ signal induces the interaction between PKS5 and 14-3-3 and thus releases the inhibition of SOS2.”

(2002, background): “Salt upregulation of SOS1 expression is partially under the control of the SOS2/SOS3 regulatory pathway (Halfter et al., 2000; Liu et al., 2000; Shi et al., 2000; Zhu, 2000).”

(2013, background): “There is compelling evidence gathered over the years that, after perception of salt stress, a Ca2+ spike generated in cytoplasms of root cells activates the SOS signal transduction cascade to protect the cells from damage due to excessive ion accumulation (Knight, 1999; Halfter et al., 2000; Zhu, 20”
Smart Engineering of Genetic Resources for Enhanced Salinity Tolerance in Crop Plants (2016, background): “Interaction between SOS3 and SOS2 regulates kinase activity of SOS2 (Halfter et al., 2000; Qiu et al., 2002), which in turn phosphorylates SOS1 leading to increased SOS1 transport activity.”

(2002, background): “Genetic analysis indicated that SOS1, SOS2 and SOS3 function in a common pathway in controlling salt tolerance (Zhu et al., 1998; Halfter et al., 2000), and functional studies in yeast and plants have shown that SOS1 is activated by the SOS3–SOS2 complex.”
Cold, salinity and drought stresses: an overview. (2005, background): “Arabidopsis plants with double mutant genotype (sos3/sos2) showed no additive eVects towards salt sensitivity, this indicates that SOS3 and SOS2 function in the same pathway [63].”

Roles of enzymatic and nonenzymatic antioxidants in plants during abiotic stress (2010, background): “However, unlike the calcineurin-b in yeast that acts through activation of a protein phosphatase, SOS3 interacts with and activates (Halfter et al., 2000) protein kinase SOS2.”
