Due to a typographical error, the genotypes of two yeast strains were reported incorrectly. The corrected genotypes are shown as follows: RKY1732 (MATα, leu2, cyh2r, ura3, trp1), RKY1942 (MATα, leu2, cyh2r, ura3, trp1, msh2Δ::hisG). A National Institutes of Health grant number was erroneously described as GM50006; it is, in fact, GM44704.
