2.A.36.7.10 Na+/H+ antiporter of 1145 aas and 12 TMSs, SOS1. Suppresses salt (200 mM NaCl) sensitivity, promoting tolerance (Wu et al. 2007). It is 65% identical to the A. thaliana homologue (TC# 2.A.36.7.6). In Solanum tuberosum, there are 37 salt overly sensitive 1 (SOS1) genes (Liang et al. 2023). Most of the gene products are located in the plasma membrane. Promoter analysis revealed that the majority of these StSOS1 genes contain abundant cis-elements involved in various abiotic stress responses. Tissue specific expression showed that 21 of the 37 StSOS1s are widely expressed in various tissues or organs of the potato. Molecular interaction network analysis suggests that 25 StSOS1s may interact with other proteins involved in potassium ion transmembrane transport and response to salt stress. RT-qPCR results revealed that the expression of StSOS1s are significant modulated by various abiotic stresses, in particular salt and abscisic acid stress (Liang et al. 2023).
