Abstract:
:Saccharomyces bayanus var. uvarum investigated here is the species closest to Saccharomyces cerevisiae. Random sequence tags (RSTs) allowed us to identify homologues to 2789 open reading frames (ORFs) in S. cerevisiae, ORFs duplicated in S. uvarum but not in S. cerevisiae, centromeres, tRNAs, homologues of Ty1/2 and Ty4 retrotransposons, and a complete rDNA repeat. Only 13 RSTs seem to be homologous to sequences in other organisms but not in S. cerevisiae. As the synteny between the two species is very high, cases in which synteny is lost suggest special mechanisms of genome evolution. The corresponding RSTs revealed that S. uvarum can exist without any S. cerevisiae DNA introgression. Accession numbers are from AL397139 to AL402278 in the EMBL databank.
