Résumé
The genome of
Saccharomyces servazzii was analyzed with 2570 random sequence tags totalling 2.3 Mb. BLASTX comparisons revealed a minimum of 1420 putative open reading frames with significant homology to
Saccharomyces cerevisiae (58% aa identity on average), two with
Schizosaccharomyces pombe and one with a human protein, confirming that
S. servazzii is closely related to
S. cerevisiae. About 25% of the
S. servazzii genes were identified, assuming that the gene complement is identical in both yeasts.
S. servazzii carries very few transposable elements related to Ty elements in
S. cerevisiae. Most of the mitochondrial genes were identified in eight contigs altogether spanning 25 kb for a predicted size of 29 kb. A significant match with the
Kluyveromyces lactis linear DNA plasmid pGKL-1 encoded RF4 killer protein suggests that a related plasmid exists in
S. servazzii. The sequences have been deposited with EMBL under the accession numbers
AL402279–
AL404848.
