    R-spondins engage heparan sulfate proteoglycans to potentiate WNT signaling

    Ramin Dubey et al.
    Heparan Sulfate Proteoglycans function as receptors for the R-spondins, a family of growth factors that amplify the strength of WNT signaling during development and in adult stem cells.

    A combination of transcription factors mediates inducible interchromosomal contacts

    Seungsoo Kim et al.
    A pooled mutational scanning approach for 3D chromosome conformation reveals how multiple transcription factors can jointly specify condition-specific genome conformations.

    Dosage compensation can buffer copy-number variation in wild yeast

    James Hose et al.
    Dosage-compensated gene expression facilitates chromosomal aneuploidy, which presents a rapid route to phenotypic evolution in natural yeast isolates.

    Atypical meiosis can be adaptive in outcrossed Schizosaccharomyces pombe due to wtf meiotic drivers

    María Angélica Bravo Núñez et al.
    The wtf meiotic drivers change the fitness landscape of meiosis in outcrossed Schizosaccharomyces pombe demonstrating that genetic parasites can favor the evolution of variants that disrupt meiotic fidelity.

    The structures of secretory and dimeric immunoglobulin A

    Sonya Kumar Bharathkar et al.
    The structures of secretory and dimeric IgA reveal pseudosymmetric assemblies of two antibody monomers, in which possible positions of antigen-binding fragments and accessibility to receptor-binding sites are limited.

    Loss of heterozygosity results in rapid but variable genome homogenization across yeast genetic backgrounds

    Abhishek Dutta et al.
    Loss of heterozygosity (LOH) mediated diversification of the diploid S. cerevisiae hybrid genomes during asexual propagation are vast and exceptionally varied depending on the genetic background.

    Aneuploidy as a cause of impaired chromatin silencing and mating-type specification in budding yeast

    Wahid A Mulla et al.
    Genetic analyses reveal that purely quantitative changes in the relative copy number of chromosomes can be sufficient to disrupt the epigenetic mechanisms that define the cells' differentiated state.

    Chromosome mis-segregation and cytokinesis failure in trisomic human cells

    Joshua M Nicholson et al.
    Aneuploidy can cause chromosome mis-segregation and specific cellular phenotypes driven by expression of genes on the extra chromosome.

    Polyploidy in the adult Drosophila brain

    Shyama Nandakumar et al.
    Terminally differentiated neurons and glia can re-enter the cell cycle to become polyploid in the adult fly brain, to protect cells from DNA damage-associated death.

    A complete toolset for the study of Ustilago bromivora and Brachypodium sp. as a fungal-temperate grass pathosystem

    Franziska Rabe et al.
    The establishment of Ustilago bromivora and Brachypodium as a biotrophic model system provides the foundation for studying new aspects of plant-pathogen interactions and for answering questions about fungal sex and speciation.
