Overexpression of Ycg1 or Ydr520c confers resistance to cadmium in Saccharomyces cerevisiae

Abstract

We introduced a yeast open reading frame library into Saccharomyces cerevisiae strain BY4742 to search for genes whose overexpression conferred cadmium resistance to yeast, toward the goal of elucidating the mechanism of cadmium toxicity. As a result, we found that the overexpression of two newly identified genes, Ycgl and Ydr520c, each conferred strong cadmium resistance to yeast.
