The capacity to transport potassium and to discriminate between the different alkali cations has been found to affect sodium tolerance in Saccharomyces cerevisiae. Mutants with a defective capacity to transport K+ were more sensitive to high concentrations of Na+ because they accumulated more Na+ and less K+ than wild-type cells which showed high discrimination between K+ and Na+.
已发现酿酒酵母中运输钾以及区分不同碱金属阳离子的能力会影响其对钠的耐受性。运输K⁺能力有缺陷的突变体对高浓度Na⁺更为敏感，因为与对K⁺和Na⁺有高度区分能力的野生型细胞相比，它们积累了更多的Na⁺和更少的K⁺。
