The capacity to transport potassium influences sodium tolerance inSaccharomyces cerevisiae

Abstract
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+.
