Yeasts illustrate the molecular mechanisms of eukaryotic genome evolution
Abstract
Hemiascomycetous yeasts have the greatest number of sequenced species for a single phylum, and are at the forefront of evolutionary genomics of eukaryotes. Yeast genomes show the dynamic interplay between the formation and loss of genes and help to characterize the mechanisms involved and their functional and evolutionary consequences. These mechanisms have equivalents in the genomes of multicellular organisms. Yeast genomes show extensive loss of introns and a reduced role of transposable elements, and so probably have a more limited potential to form novel genes and functions than multicellular organisms, possibly explaining their conserved biological and morphological properties despite their considerable evolutionary range.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
