Copper tolerance and SO2 tolerance are two well-studied phenotypic traits of Saccharomyces cerevisiae. The genetic bases of these traits are the allelic expansion at the CUP1 locus and reciprocal translocation at the SSU1 locus. respectively. Previous work identified a negative association between SO2 and copper tolerance in S. https://www.chiggate.com/turbo-air-m3f72-3-n-78-wide-m3-series-reach-in-freezer-featuring-three-solid-doors-energy-star-online-now/
