    The kinetochore prevents centromere-proximal crossover recombination during meiosis

    Nadine Vincenten et al.
    The meiotic DNA recombination landscape is locally influenced by the kinetochore to minimize potentially deleterious pericentromeric crossover recombination.

    A high-resolution map of transcriptional repression

    Ziwei Liang et al.
    High resolution mapping of transcriptional repression reveals complex and interdependent mechanisms that underpin rapid transitions between transcriptional states.

    A histone H3K9M mutation traps histone methyltransferase Clr4 to prevent heterochromatin spreading

    Chun-Min Shan et al.
    A lysine-to-methionine mutation in histone H3 dominantly blocks histone H3K9 methylation by trapping its methyltransferase.

    Histone H3G34R mutation causes replication stress, homologous recombination defects and genomic instability in S. pombe

    Rajesh K Yadav et al.
    Mutation of Glycine 34 to Arginine within the N-terminal tail of histone H3 alters post-translational modifications on Lysine 36 and is associated with a delay in replication restart, defective homologous recombination and an increase in genomic instability.

    Adaptive evolution of an essential telomere protein restricts telomeric retrotransposons

    Bastien Saint-Leandre et al.
    Evolution strictly preserves telomere stability but rapidly diversifies telomere length regulation in Drosophila.

    ATRX promotes maintenance of herpes simplex virus heterochromatin during chromatin stress

    Joseph M Cabral et al.
    Epigenetic restriction of herpes simplex virus occurs in a biphasic manner, in which ATRX maintains viral heterochromatin after an initial phase of chromatin deposition.

    The human origin recognition complex is essential for pre-RC assembly, mitosis, and maintenance of nuclear structure

    Hsiang-Chen Chou et al.
    The initiation of human genome replication requires the six-subunit origin recognition complex (ORC) and CDC6, with ORC playing additional roles during mitosis and in organization of the cell nucleus.
    1. Chromosomes and Gene Expression

    Condensin controls cellular RNA levels through the accurate segregation of chromosomes instead of directly regulating transcription

    Clémence Hocquet et al.
    Contrary to the generally accepted model, condensin maintains proper gene expression by promoting the accurate segregation of chromosomes and the partitioning of the RNA-exosome throughout mitosis, instead of directly regulating transcription.

    The Aquilegia genome provides insight into adaptive radiation and reveals an extraordinarily polymorphic chromosome with a unique history

    Danièle L Filiault et al.
    The evolution columbine genus involved frequent mixing between incipient species, and one chromosome appears to have taken its own path.

    Modifications at K31 on the lateral surface of histone H4 contribute to genome structure and expression in apicomplexan parasites

    Fabien Sindikubwabo et al.
    A versatile acetylation-methylation switch at lysine 31 on the lateral surface of histone H4 contributes to chromatin structure in apicomplexan parasites.
