title: Induction of respiration-deficient mutants in Saccharomyces cerevisiae by chelerythrine.
abstract: Chelerythrine and sanguinarine, two structurally related benzo/c/phenanthridine alkaloids, prevented growth of yeast cells in medium containing either glucose or non-fermentable carbon sources. At concentrations permitting growth of the yeast Saccharomyces cerevisiae, chelerythrine, but not sanquinarine, induced cytoplasmic respiration-deficient mutants. The petite clones that were analysed exhibited suppressiveness and contained different fragments of the wild-type mitochondrial genome.
