    Genome rearrangements and pervasive meiotic drive cause hybrid infertility in fission yeast

    Sarah E Zanders, Michael T Eickbush ... Harmit Singh Malik
    Rapid acquisition of chromosome rearrangements, together with independently acting transmission distorter alleles on each chromosome, drive near complete sterility in fission yeast hybrids.

    Catastrophic chromosomal restructuring during genome elimination in plants

    Ek Han Tan, Isabelle M Henry ... Simon WL Chan
    Complex chromosomal rearrangements similar to those described in cancer and developmental syndromes occur in plants during postzygotic genome elimination, a centromeric-derived incompatibility.

    Mechanisms underlying genome instability mediated by formation of foldback inversions in Saccharomyces cerevisiae

    Bin-zhong Li, Christopher D Putnam, Richard David Kolodner
    Genetic analysis combined with whole genome sequencing elucidates mechanisms and pathways that form and prevent a specific class of genome rearrangements, foldback inversions, seen in many human cancers.

    Micronuclei-based model system reveals functional consequences of chromothripsis in human cells

    Maja Kneissig, Kristina Keuper ... Zuzana Storchova
    A method to generate human cells with massive chromosomal aberrations on a specific chromosome allows analysis of their consequences.

    Spatial inter-centromeric interactions facilitated the emergence of evolutionary new centromeres

    Krishnendu Guin, Yao Chen ... Kaustuv Sanyal
    Proximity and homology guided inter-chromosomal translocations drive karyotype evolution.

    Structure of the germline genome of Tetrahymena thermophila and relationship to the massively rearranged somatic genome

    Eileen P Hamilton, Aurélie Kapusta ... Robert S Coyne
    The model organism Tetrahymena thermopile carries two nuclei with distinct genomes: an unrearranged germline genome with five chromosomes, and a somatic genome reduced in size by a third and with 181 chromosomes.

    Comparative genomics reveals insight into the evolutionary origin of massively scrambled genomes

    Yi Feng, Rafik Neme ... Laura F Landweber
    The comparison of three ciliate species that share complex pathways for natural genome editing allows capture of intermediate states in the acquisition of scrambled genes and elucidating a pathway for the origin and evolution of extremely rearranged chromosomes.

    SPOP mutation leads to genomic instability in prostate cancer

    Gunther Boysen, Christopher E Barbieri ... Mark A Rubin
    SPOP mutations underlie a novel, genomically unstable subclass of prostate cancer by altering DNA repair.

    Genome plasticity in Candida albicans is driven by long repeat sequences

    Robert T Todd, Tyler D Wikoff ... Anna Selmecki
    Previously uncharacterized long repeat sequences are associated with significant genome variation that can increase fitness and promote antifungal drug resistance in diverse isolates of Candida albicans.

    Chromosome territory formation attenuates the translocation potential of cells

    Leah F Rosin, Olivia Crocker ... Eric F Joyce
    The translocation potential of cells can be modulated by Condensin II activity during interphase.
