Yeast strains were patched onto YP-Glycerol plates and transferred to YP-4%Dextrose plates. After this, cells were grown overnight in liquid YPD culture (room temperature) followed by inoculation in pre-sporulation media (BYTA; 50 mM Sodium Phthalate-buffered, 1% yeast extract, 2% tryptone, and 1% acetate) at OD600 = 0.3. Cells were grown for 18 hr in BYTA at 30°C, washed twice in water and resuspended in sporulation media (0.3% potassium acetate) at OD600 = 1.9 to induce meiosis at 30°C.
