Abstract

Mn²⁺ and Mg²⁺ uptake was studied in a wild type strain of S. cerevisiae and in a mutant resistant to Mn²⁺. Contrary to expectations, the resistant strain accumulates Mn²⁺ to a higher concentration than the wild type strain, while Mg²⁺ uptake is unaffected. Moreover, the transmembrane electric potential (PD) of the resistant strain is far less depolarized by Mn²⁺ than that of the sensitive strain. A possible explanation for these results is discussed.
