  • a All transformations included a CAS9 gene, following the method of Min et al. (10). Approximate amounts of each PCR product in a typical transformation were the following (unless otherwise stated within the table): CAS9, 1 µg; sgRNA1, 1 µg; sgRNA2, 1 µg; split-marker cassette A, 1.5 µg; split marker cassette B, 1.5 µg.

  • b All strains are of genotype his1Δ/his1Δ leu2Δ/leu2Δ arg4Δ/arg4Δ. MH101 has the additional genotype ume6Δ::r1HIS1r1/ume6Δ::r1HIS1r1. MH110 has the additional genotype ume6Δ::r1/ume6Δ::r1 brg1Δ::r2LEU2r2/brg1Δ::r2LEU2r2, in which the ume6Δ::r1 allele is marked only with one copy of the flanking repeat from the r1HIS1r1 marker cassette.
