    The role of Rif1 in telomere length regulation is separable from its role in origin firing

    Calla B Shubin, Carol W Greider
    Telomere length is linked to DNA replication, and we found excessive telomeric origin firing caused by several distinct mutants did not lengthen telomeres, narrowing possible mechanisms.

    A conserved RNA degradation complex required for spreading and epigenetic inheritance of heterochromatin

    Gergana Shipkovenska et al.
    Genetic and biochemical studies show that a conserved ribosome biogenesis complex also localizes to heterochromatin, where it triggers RNA degradation and promotes the spreading and epigenetic inheritance of histone methylation.

    Telomere dysfunction cooperates with epigenetic alterations to impair murine embryonic stem cell fate commitment

    Mélanie Criqui et al.
    Cell lineage tracing and biochemical analysis of cell fate during murine stem cell differentiation demonstrates a specific cooperativity between perturbations in histone methylation and eroded telomeres that destabilize cell differentiation.

    Centromere deletion in Cryptococcus deuterogattii leads to neocentromere formation and chromosome fusions

    Klaas Schotanus, Joseph Heitman
    Centromere deletion in Cryptococcus deuterogattii results in neocentromeres, which span actively expressed genes and at elevated temperatures cen10∆ mutants are unstable leading to chromosome fusion and silencing of the neocentromere.

    TRF1 averts chromatin remodelling, recombination and replication dependent-break induced replication at mouse telomeres

    Rosa Maria Porreca et al.
    TRF1 suppresses replication fork stalling, which triggers break induced replication at telomeres associated with DNA damage response, alteration in the telomere chromatin environment, and re-localisation of telomeres to PML bodies.

    Comprehensive annotations of human herpesvirus 6A and 6B genomes reveal novel and conserved genomic features

    Yaara Finkel et al.
    Unbiased mapping of viral open reading frames (ORFs) and transcripts in HHV-6 genomes uncovers novel ORFs and lncRNAs that are conserved across betaherpesviruses.

    Persistent epigenetic memory impedes rescue of the telomeric phenotype in human ICF iPSCs following DNMT3B correction

    Shir Toubiana et al.
    Correction of the DNA methyltransferase 3B gene in ICF1 syndrome fails to rescue the abnormal DNA hypomethylation at subtelomeric regions due to accompanied epigenetic abnormalities in these regions.

    TERRA regulate the transcriptional landscape of pluripotent cells through TRF1-dependent recruitment of PRC2

    Rosa María Marión et al.
    Telomeric TRF1 controls the transcriptional programmes of pluripotent stem cells by recruiting PRC2 to pluripotency and differentiation genes by controlling the expression of those gene sites and the binding of TERRA RNAs to them.

    Combinations of Spok genes create multiple meiotic drivers in Podospora

    Aaron A Vogan et al.
    Members of a single gene family determine the genomic basis of multiple coexisting meiotic drive elements in natural populations of Podospora.

    The genomes of polyextremophilic cyanidiales contain 1% horizontally transferred genes with diverse adaptive functions

    Alessandro W Rossoni et al.
    Horizontal gene transfer (HGT) analysis in polyextremophile red algae (Cyanidiales) provides explanations for the nonexistence of cumulative effects and eukaryotic pangenomes, and highlights differences between HGT and native genes.
