TABLE 3.

Mating efficiencies of strains with different alleles of SIR1 and YKU70

Mating efficiencies
Relevant genotype HMR HML
Wild type 1.0 1.0
yku70Δ∷natMX4 1.05 ± 0.11 0.81 ± 0.14
sir1Δ∷kanMX4 0.72 ± 0.13 0.65 ± 0.10
yku70Δ∷natMX4 sir1Δ∷kanMX4 3.6 × 10−2 ± 4.0 × 10−3 0.26 ± 0.14

All strains were isogenic to W303. At least three independent mating assays were performed on all strains and the averages and standard error are reported. MATα strains were used to determine mating efficiencies for HMR, and MATa strains were used to determine mating efficiencies for HML. Strains tested were DRY705 (wild type), DRY5438 (yku70Δ), DRY5439 (sir1Δ), and DRY5440 (yku70Δ sir1Δ) at HMR and DRY5430 (wild type), DRY5431 (yku70Δ), DRY5432 (sir1Δ), and DRY5433 (yku70Δ sir1Δ) at HML.
