ABSTRACT

HERMAN, ALBERTA (University of Wisconsin, Madison) AND HARLYN HALVORSON. Genetic control of ß-glucosidase synthesis in Saccharomyces lactis. J. Bacteriol. 85:901–910. 1963.—Both methyl-ß-D-glucoside (2 x 10^–2M) and glucose (10^–3M) induced ß-glucosidase synthesis in selected strains of Saccharomyces lactis. Genetic studies indicated the existence of a single locus specifically affecting ß-methyl glucoside inducibility. Glucose-induced ß-glucosidase synthesis, on the other hand, was nonspecific (other carbohydrases were simultaneously induced) and appeared to be controlled by more than one genetic factor. In both cases, noninducibility was dominant in diploids. The independent expression of these two modes of induction implied that these loci regulated ß-glucosidase induction in a nonsequential manner.
