Random sequence tags were obtained from a genomic DNA library of Saccharomyces exiguus . The mitochondrial genome appeared to be at least 25.7 kb in size, with a different organization compared to Saccharomyces cerevisiae . An unusual putative 953 bp long terminal repeated element associated to Ty3 was found. A set of 1451 genes was identified homologous to S. cerevisiae open reading frames. Only five genes were identified outside the S. cerevisiae taxon, confirming that S. exiguus is phylogenetically closely related to S. cerevisiae . Unexpectedly, numerous duplicated genes were found whereas they are unique in S. cerevisiae . The sequences are deposited at EMBL under the accession numbers: AL407377–AL409955.
