Much is already known about the function and functioning of the three genes that make up the SOS (Salt-Overly-Sensitive) pathway in plants, but recent studies indicate that the linkage between external increases in salinity and stress protection provided by genes SOS1, SOS2 and SOS3 is more complex than previously appreciated. It has recently been shown that the engineered reduced expression of the sodium/proton antiporter SOS1 affected several pathways indicating a role for SOS1 that exceeds its known function as an antiporter. Interference with expression of SOS1, characterized as a sodium/proton antiporter in the halophyte Thellungiella salsuginea converted Thellungiella into an essentially glycophytic species.
关于构成植物 SOS（盐过度敏感）途径的三个基因的功能和作用，人们已经了解很多，但最近的研究表明，外部盐度增加与 SOS1、SOS2 和 SOS3 基因提供的应激保护之间的联系比以前认为的更为复杂。最近表明，工程改造降低 SOS1 钠/质子反向转运蛋白的表达影响了几个途径，表明 SOS1 的作用超出了其作为反向转运蛋白的已知功能。在盐生植物 Thellungiella salsuginea 中，干扰 SOS1 的表达，其特征为一种钠/质子反向转运蛋白，将 Thellungiella 转化为基本上的嗜盐植物。
