The fission yeast clade--comprising Schizosaccharomyces pombe, S. octosporus, S. cryophilus, and S. japonicus--occupies the basal branch of Ascomycete fungi and is an important model of eukaryote biology. A comparative annotation of these genomes identified a near extinction of transposons and the associated innovation of transposon-free centromeres.(More)
Shortened kinetochore microtubules take separated chromatids to the opposing spindle poles in anaphase. Fission yeast Dis1 belongs to the Dis1/XMAP215/TOG family that is required for proper microtubule dynamics. Here, we report that Dis1is regulated by Cdc2 phosphorylation and that this mitotic phosphorylation ensures the fidelity of chromosome segregation.(More)
DNA replication initiates at distinct origins in eukaryotic genomes, but the genomic features that define these sites are not well understood. We have taken a combined experimental and bioinformatic approach to identify and characterize origins of replication in three distantly related fission yeasts: Schizosaccharomyces pombe, Schizosaccharomyces(More)
