    Notes: Summary We have used cytoduction and protoplast fusion to characterise the killer trait in Torulopsis glabrata. Killer trait could not be transferred by cytoduction to a non-killer strain of T. glabrata suggesting that the determinant(s) is/are not present in the cytoplasm. Consistent with this interpretation is the observation that all fusion products, where chromosomes of both the parents are represented, are killers. Non-killer segregants could be isolated from fusion products after treatment with benlate suggesting that loss of the trait is associated with non-disjunction and loss of a chromosome.

    Notes: Summary Using a protoplast fusion technique we have been able to locate to the mitochondrial genome of the asporogenous yeast Torulopsis glabrata mutations conferring resistance to oligomycin, antimycin and diuron. When two strains differing in the size of their mtDNAs were fused the mitochondrial markers from the parent with the larger mtDNA (71–91) were transmitted predominantly among the fusion products. Both genetical and physical evidence support the occurrence of recombination in T. glabrata mitochondrial genome. Segregation of the mitochondrial genome appears to take place before the separation of the first bud from the fusion product.
