RESUMO

Yeasts exhibit various mechanisms for the inheritance of their mitochondrial genomes. Differences among these mechanisms are based on variations within nuclear as well as mitochondrial genetic elements. Here we report diagnostic differences in the presence of biologically active mitochondrial intergenic sequences, ori-reptra, among related yeasts in the genera Saccharomyces, Arxiozyma, Debaryomyces, Kluyveromyces, Pachytichospora, Torulaspora, and Zygosaccharomyces. A molecular probe containing ori-rep-tra can be employed specifically for the differentiation and identification of isolates belonging to the species complex Saccharomyces sensu stricto.
