✦ Synopsis

A series of yeast mutants has been isolated with the inability to grow on fermentable carbon sources whilst growing normaily on ethanol media. One of the mutants, namely MC16/ 206 lacks pyruvate decarboxylase activity and does not grow on glucose at 37Β°C but grows on both ethanol and glucose at 27 Β° C. In this strain rhopetites are non-viable.

A mutant of Saccharomyces cerevisiae has been isolated which, though exhibiting a normal response to nuclear genetic damage by ultraviolet light (UV), is more sensitive than its wild type specifically in the production of the cytoplasmic (rho-) mutation by this agent.

Mutations in two genes (cdc8 and cdc21) required for nuclear and mitochondrial DNA synthesis in Saccharomyces cerevisiae result in a 6- to 11-fold increase in the rate of mitotic segregation of petites at the permissive temperature. The defect in DNA replication and the increased rate of petite prod
