Genomic exploration of the hemiascomycetous yeasts: 8. Zygosaccharomyces rouxii.

This paper reports the genomic analysis of strain CBS732 of Zygosaccharomyces rouxii, a homothallic diploid yeast. We explored the sequences of 4934 random sequencing tags of about 1 kb in size and compared them to the Saccharomyces cerevisiae gene products. Approximately 2250 nuclear genes, 57 tRNAs, the rDNA locus, the endogenous pSR1 plasmid and 15 mitochondrial genes were identified. According to 18S and 25S rRNA cladograms and to synteny analysis, Z. rouxii could be placed among the S. cerevisiae sensu lato yeasts.
