Genomic exploration of the hemiascomycetous yeasts: 12. Kluyveromyces marxianus var. marxianus.
As part of the comparative genomics project 'GENOLEVURES', we studied the Kluyveromyces marxianus var. marxianus strain CBS712 using a partial random sequencing strategy. With a 0.2 x genome equivalent coverage, we identified ca. 1300 novel genes encoding proteins, some containing spliceosomal introns with consensus splice sites identical to those of Saccharomyces cerevisiae, 28 tRNA genes, the whole rDNA repeat, and retrotransposons of the Ty1/2 family of S. cerevisiae with diverged Long Terminal Repeats. Functional classification of the K. marxianus genes, as well as the analysis of the paralogous gene families revealed few differences with respect to S. cerevisiae. Only 42 K. marxianus identified genes are without detectable homolog in the baker's yeast. However, we identified several genetic rearrangements between these two yeast species.
