Summary: In this study, 37 StSOS1 genes were identified and found to be unevenly distributed across 10 chromosomes in potato, with most of them located on the plasma membrane. These genes contain abundant cis-elements involved in various abiotic stress responses. Tissue specific expression showed that 21 of the 37 StSOS1 genes were widely expressed in various tissues or organs of the potato. Molecular interaction network analysis suggests that these genes may interact with other proteins involved in potassium ion transmembrane transport, response to salt stress, and cellular processes. Collinearity analysis showed orthologous StSOS1 genes in tomato, pepper, tobacco, and Arabidopsis. Moreover, the expression of StSOS1 genes were significantly modulated by various abiotic stresses, especially salt and abscisic acid stress. Subcellular localization in Nicotiana benthamiana suggested that StSOS1-13 was located on the plasma membrane. These results provide a comprehensive overview of the StSOS1 gene family and pave the way for further analysis of their function in SOS and hormone signaling pathways.

Summary: In this study, the gene expression differences between control and water-stressed potato plants were analyzed using RNAseq. The variety Agria showed a better stress response compared to Zorba, with more differentially expressed genes (DEGs) detected. The most highly expressed gene under drought conditions was Abscisic acid and environmental stress-inducible protein TAS14-like. Several metabolic pathways and cellular components were found to be affected by water stress, providing valuable information for breeding more tolerant potato varieties.
