A direct relationship between pantothenate concentration and the time required to induce the production of pantothenate-synthe-sizing mutants in yeast



A direct relationship between pantothenate concentration and the time required to induce the production of pantothenate-synthe-sizing mutants in yeast



Ann. Mo. Bot. Gdn. 34: 85-93



"Non-synthesizing" cultures of yeast are described which synthesize pantothenate when the concentration of pantothenate in the medium falls below the minimum required for growth. The rate of growth is independent of the concentration of pantothenate below the amount of 2 y per litre, but the time at which the "mutation" is induced, or the delay in growth, depends upon the concentration of pantothenate.
