    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.

    Two consecutive microtubule-based epithelial seaming events mediate dorsal closure in the scuttle fly Megaselia abdita

    Juan Jose Fraire-Zamora, Johannes Jaeger, Jérôme Solon
    Evolutionary reduction in tissue number involves the simplification of the seaming process but not signaling during epithelial fusion.

    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.

    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.

    Epistatic selection on a selfish Segregation Distorter supergene – drive, recombination, and genetic load

    Beatriz Navarro-Dominguez, Ching-Ho Chang ... Amanda M Larracuente
    African haplotypes of a meiotic drive supergene in Drosophila melanogaster called Segregation Distorter show signs of a recent selective sweep, reduced recombination, and increased genetic load.

    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.

    Planar cell polarity signaling coordinates oriented cell division and cell rearrangement in clonally expanding growth plate cartilage

    Yuwei Li, Ang Li ... Marianne Bronner
    Through the interaction between PCP signaling and N-cadherin, oriented cell division and cell rearrangement are coordinated to establish the appropriate tissue architecture critical for limb skeletal morphogenesis.

    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.

    Emx2 regulates hair cell rearrangement but not positional identity within neuromasts

    Sho Ohta, Young Rae Ji ... Doris K Wu
    Emx2 is not required for sibling HCs to acquire their designated locations within the neuromast, inferring that Emx2 mediates opposite HC orientation by changing location of hair bundle establishment.

    A common 1.6 mb Y-chromosomal inversion predisposes to subsequent deletions and severe spermatogenic failure in humans

    Pille Hallast, Laura Kibena ... Maris Laan
    In addition to its academic merits, characterizing the genetic determinants of male (in)fertility and identifying clinically actionable genetic variants can lead to improved diagnosis or even treatment of such conditions.
