abstract：:A cadmium-resistant strain of Saccharomyces cerevisiae produces a cadmium metallothionein encoded by the CUP1 gene as does a copper-resistant strain. The mechanism of expression of the gene is inducible by copper ions in the copper-resistant strain. However, assays of CUP1-specific mRNA revealed that the transcription...
