Homothallic Saccharomyces cerevisiae, growing exponentially in a synthetic acetate medium, could be initiated to undergo meiosis and subsequent sporulation by removal of sulfur from the medium or by partial purine deprivation of purine auxotrophs or, most efficiently, by guanine deprivation of a guanine auxotroph. In contrast, partial uracil deprivation of uracil auxotrophs did not cause sporulation. Under any of the above and other sporulation conditions, the intracellular concentrations of… CONTINUE READING
