    Heterochromatin assembly and transcriptome repression by Set1 in coordination with a class II histone deacetylase

    David R Lorenz et al.
    Set1 has roles in chromatin organization and transcriptome control that are largely independent of histone H3 lysine 4 methylation.

    Mapping replication dynamics in Trypanosoma brucei reveals a link with telomere transcription and antigenic variation

    Rebecca Devlin et al.
    Mapping DNA replication timing, allied to genetic analysis of a RecQ repair helicase, reveals that antigenic variation in the African trypanosome may be initiated by locus-specific, replication-derived sequence instability.

    The antigenic switching network of Plasmodium falciparum and its implications for the immuno-epidemiology of malaria

    Robert Noble et al.
    The first comprehensive analysis of antigenic switching in the malaria-causing parasite Plasmodium falciparum provides new insights into the process that prevents individuals from acquiring immunity to the disease.

    ASH1-catalyzed H3K36 methylation drives gene repression and marks H3K27me2/3-competent chromatin

    Vincent T Bicocca et al.
    While SET-2 methylates histone H3K36 during transcription, ASH1 methylates this residue in repressed regions, is important for silencing, and can both positively and negatively influence methylation of histone H3K27.

    Surprising phenotypic diversity of cancer-associated mutations of Gly 34 in the histone H3 tail

    Brandon R Lowe et al.
    H3-G34R, V, and W oncohistonesin fission yeast cause differential K36 modification, DNA damage sensitivity and genome stability outcomes, highlighting the need for a thorough evaluation of distinct mutations.

    Telomere repeats induce domains of H3K27 methylation in Neurospora

    Kirsty Jamieson et al.
    Vast regions of facultative heterochromatin marked by methylation of lysine 27 on histone H3 depend on their proximity to chromosome ends and can be induced ectopically by insertion of telomere repeats.

    The Ku subunit of telomerase binds Sir4 to recruit telomerase to lengthen telomeres in S. cerevisiae

    Evan P Hass, David C Zappulla
    In yeast, the secondary pathway for recruiting telomerase to chromosome ends requires a component of telomeric transcriptionally silent chromatin.

    Variation in human herpesvirus 6B telomeric integration, excision, and transmission between tissues and individuals

    Michael L Wood et al.
    Human herpesvirus 6B can transition between telomere-integrated and free viral forms, and frequent telomere-loop-driven partial or complete viral genome excision events create mosaicism in germline carriers of inherited chromosomally integrated HHV-6B.

    Rapid epigenetic adaptation to uncontrolled heterochromatin spreading

    Jiyong Wang et al.
    Redundant pathways prevent heterochromatin spreading and ectopic heterochromatin assembly; and plasticity of heterochromatin assembly allows cells to adapt to heterochromatin stress.

    Non-crossover gene conversions show strong GC bias and unexpected clustering in humans

    Amy L Williams et al.
    In humans, non-crossover gene conversion events transmit GC alleles in 68% of cases and exhibit a complex pattern of multiple disconnected tracts clustered within 20–30 kilobase intervals.
