Mtdna Recombination

AbstractmtDNA recombination events in yeasts are known, but altered mitochondrial genomes were not completed. Therefore, we analyzed recombined mtDNAs in six Saccharomyces cerevisiae × Saccharomyces paradoxus hybrids in detail. Assembled molecules contain mostly segments with variable length introgressed to other mtDNA. All recombination sites are in the vicinity of the mobile elements, introns in cox1, cob genes and free standing ORF1, ORF4. The transplaced regions involve co-converted proximal exon regions. Thus, these selfish elements are beneficial to the host if the mother molecule is challenged with another molecule for transmission to the progeny. They trigger mtDNA recombination ensuring the transfer of adjacent regions, into the progeny of recombinant molecules. The recombination of the large segments may result in mitotically stable duplication of several genes.

AbstractIn this study, yeast was isolated from cherry wine lees by rose Bengal medium, and its species was identified through three-stage screening, morphological observation and molecular biological identification. Moreover, the tolerance of screened strains was studied. The results showed that 30 strains of yeast were isolated from cherry wine lees, and five strains of yeast were selected, which were named YJN10, YJN16, YJN18, YJN19 and YJN28. After preliminary appraisal, strain YJN10 was Saccharomyces kudriavzevii, strain YJN16 was Saccharomyces paradoxus, and strains YJN18, YJN19, YJN28 were Saccharomyces cerevisiae. In the tolerance study, the tolerable sugar concentrations of the five strains were 650, 650, 550, 600 and 600 g/L. The tolerable alcohol volume fractions were 20, 20, 16, 18 and 18%. The tolerable molar concentration of potassium chloride was 1.8, 1.8, 1.5, 1.5 and 1.5 mol/L. Finally, strains YJN10, YJN16, YJN19 and YJN28 showed good tolerance, which laid a foundation for subsequent application in cherry wine fermentation.

Genetic hybridization and karyotypic analyses revealed the biological species Saccharomyces paradoxus and Saccharomyces cerevisiae in exudates from North American oaks for the first time. In addition, two strains collected from elm flux and from Drosophila by Phaff in 1961 and 1952 were reidentified as S. paradoxus. Each strain studied showed a unique profile of chromosomal hybridization with a probe for the retrotransposable element Ty1. The wild distribution of natural Saccharomyces sensu stricto yeasts is discussed.Key words: genetical taxonomy, Saccharomyces paradoxus, oak exudates, Ty elements, electrophoretic karyotyping.
