• Overexpression of a plasma membrane Na+/H+ antiporter gene improves salt tolerance in Arabidopsis thaliana (2003, background): “thaliana SOS1 gene encodes a plasma membrane Na + /H + antiporter that is essential for salt toleranc”
• Abscisic Acid Synthesis and Response (2013, background): “In contrast, very few substrates are known for the CIPKs, but these substrates include their calcium-binding regulatory partners, the CBLs, a K+ transporter (AKT1) and a Na+/ H+ antiporter involved in salt tolerance (SOS1) (Qiu et al., 2002; Hashimoto et al., 2012).”
• Drought and Salt Tolerance in Plants (2005, background): “SOS3 forms a complex with SOS2, and this complex is necessary for the phosphorylation and subsequent activation of SOS1, the Na + /H + antiporter ( Qiu et al. , 2002 ).”
• Roles of enzymatic and nonenzymatic antioxidants in plants during abiotic stress (2010, background): “Plasma membrane vesicles from Arabidopsis plants have a Na/ H antiporter activity, which was enhanced by pretreatment with salt stress (Qiu et al., 2002).”
• Na+ tolerance and Na+ transport in higher plants. (2003, background): “It appears that in glycophytes, net Na+ uptake is regulated less by control of in¯ux than by ef¯ux of excess Na+, probably via Na+-selective Na+/H+ antiporters (Qiu et al., 2002).”
• Overexpression of AtMYB44 Enhances Stomatal Closure to Confer Abiotic Stress Tolerance in Transgenic Arabidopsis1[C][W][OA] (2007, background): “Upon salt stress, SOS2 is activated by interacting with SOS3, a calcium-binding protein (Halfter et al., 2000), and the SOS2-SOS3 kinase complex is required for activation of SOS1, a plasma membrane Na1/H1 antiporter (Shi et al., 2000; Qui et al., 2002; Quintero et al., 2002).”
• Calcium Signals: The Lead Currency of Plant Information Processing (2010, background): “The CBL Ca2+ sensor SOS3 (At CBL4) and the CIPK-type kinase SOS2 (At CIPK24) appear to be part of a Ca2+-regulated signaling pathway that specifically mediates salt stress adaptation by regulating the Na+/H+ antiporter SOS1 (Liu and Zhu, 1998; Halfter et al., 2000; Qiu et al., 2002).”
• Physiology and molecular biology of stress tolerance in plants (2006, background): “Although vesicles of sos2 and sos3 plants had reduced plasma membrane Na+/H+-exchange activity, transport ability in the mutants increased with the addition of activated SOS2 protein, indicating that SOS2 and SOS3 are involved in regulation of SOS1 transport activity (Qiu et al., 2002).”
• Molecular genetic perspectives on cross-talk and specificity in abiotic stress signalling in plants. (2003, neutral): “1) (Qiu et al., 2003).”
• Implications of Abscisic Acid in the Drought Stress Tolerance of Plants (2020, background): “Moreover, CIPKs also contain a protein phosphatase interaction (PPI) domain, which interacts with the phosphatase (PP2C) protein [49].”
• Regulation of ion homeostasis under salt stress. (2003, background): “In sos3 or sos2 mutant plants, SOS1 activity cannot be induced by salt stress [6 ].”
• Smart Engineering of Genetic Resources for Enhanced Salinity Tolerance in Crop Plants (2016, background): “NHX7 and NHX8 are found on the plasma membrane (Shi et al., 2002; Bassil et al., 2012) and due to less relationship with the other six members, are grouped into a subfamily (Pittman, 2012), whereas NHX1–6 localizes to the intracellular membranes or endomembranes (Bassil et al., 2011b; Barragan et al”
• Transgenic Plants for Abiotic Stress Resistance (2010, background): “Biochemical studies suggest that Na/H exchangers in the plasma membrane of plant cells contribute to cellular sodium homeostasis by transporting Na ions out of the cell (Qiu et al. 2002).”
