    XLF acts as a flexible connector during non-homologous end joining

    Sean M Carney et al.
    The disordered C-terminal tail allows XRCC4-like factor (XLF) to find and bind the XRCC4-Lig4 complex, enabling DNA end synapsis and subsequent ligation during non-homologous end joining.

    Programmed genome editing of the omega-1 ribonuclease of the blood fluke, Schistosoma mansoni

    Wannaporn Ittiprasert et al.
    Gene knock-out of the omega-1 ribonuclease of Schistosoma mansoni eggs resulted in immunologically impaired phenotype, showcasing the novel application of CRISPR/Cas9 genome editing and utility for functional genomics in schistosomes.

    Enhanced homology-directed human genome engineering by controlled timing of CRISPR/Cas9 delivery

    Steven Lin et al.
    Building on previous work (Jinek et al., 2013), we report a simple and robust system to achieve high fidelity and high efficiency (30% of homologous recombination) genome engineering by homology-directed repair pathway in human cells using cell cycle synchronization and timed delivery of Cas9 ribonucleoprotein complexes.

    One-step efficient generation of dual-function conditional knockout and geno-tagging alleles in zebrafish

    Wenyuan Li et al.
    Conditional gene knockout in combination with fluorescent labeling of different alleles can be achieved with high efficiency in zebrafish through NHEJ-mediated targeted insertion using a CRISPR/Cas system.

    Catastrophic chromosomal restructuring during genome elimination in plants

    Ek Han Tan et al.
    Complex chromosomal rearrangements similar to those described in cancer and developmental syndromes occur in plants during postzygotic genome elimination, a centromeric-derived incompatibility.

    MicroRNAs down-regulate homologous recombination in the G1 phase of cycling cells to maintain genomic stability

    Young Eun Choi et al.
    MicroRNAs tightly control the cellular level of homologous recombination (HR) factors in the G1 phase, and failure of this control system results in an ectopic increase in HR proteins in G1 cells leading to impaired DNA repair.

    A confinable home-and-rescue gene drive for population modification

    Nikolay P Kandul et al.
    Generation of a home-and-rescue gene drive targeting an essential gene reveals confinable population modification.

    Covalent linkage of the DNA repair template to the CRISPR-Cas9 nuclease enhances homology-directed repair

    Natasa Savic et al.
    Linking the DNA repair template to the Cas9 ribonucleoprotein complex enhances homology-directed repair of the induced DNA double strand break.

    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.
