    Recombination occurs within minutes of replication blockage by RTS1 producing restarted forks that are prone to collapse

    Michael O Nguyen et al.
    Homologous recombination is the default response to replication impedance by the RTS1 barrier, leading to restarted replication forks that suffer frequent collapse, triggering further rounds of recombination downstream of the barrier.

    53BP1 and BRCA1 control pathway choice for stalled replication restart

    Yixi Xu et al.
    53BP1 and BRCA1 antagonistically control a temporal choice of two distinct pathways to restart stalled replication forks in a DNA double stand repair-independent manner.

    p53 orchestrates DNA replication restart homeostasis by suppressing mutagenic RAD52 and POLθ pathways

    Sunetra Roy et al.
    p53 suppresses genome instability by direct role at stalled replication forks for pathway regulation that explains transcription-independent p53 tumor-suppressor functions.

    The PCNA unloader Elg1 promotes recombination at collapsed replication forks in fission yeast

    Sanjeeta Tamang et al.
    Unloading the polymerase sliding clamp PCNA from DNA by Elg1 promotes recombination at the RTS1 replication fork barrier by limiting Fbh1 and Srs2 activity.

    Translesion polymerase kappa-dependent DNA synthesis underlies replication fork recovery

    Peter Tonzi et al.
    Translesion polymerase kappa promotes replication fork restart to maintain genome stability during conditions of nucleotide deprivation.

    Factors affecting template switch recombination associated with restarted DNA replication

    Manisha Jalan et al.
    Genomic deletions and gene conversions, caused by template switching associated with restarted DNA replication, are detected downstream of a collapsed replication fork and are suppressed by several conserved DNA helicases.

    CTCF confers local nucleosome resiliency after DNA replication and during mitosis

    Nick Owens et al.
    In contrast to other transcription factors, CTCF and Esrrb rapidly regain binding after replication and remain bound to their targets during mitosis, preserving local nucleosome organization throughout the cell cycle.

    Reactivation of RNA metabolism underlies somatic restoration after adult reproductive diapause in C. elegans

    Nikolay Burnaevskiy et al.
    Morphological and functional rejuvenation upon exit from adult reproductive diapause in C. elegans is independent of germline signaling, but instead involves somatic nucleolar activation and expansion of the RNA pool.

    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.

    Inter-Fork Strand Annealing causes genomic deletions during the termination of DNA replication

    Carl A Morrow et al.
    The discovery of a mechanism that causes DNA deletions during non-canonical DNA replication termination is described.
