    Extreme positive epistasis for fitness in monosomic yeast strains

    Hanna Tutaj, Katarzyna Tomala ... Ryszard Korona
    Monosomy in yeast results in numerous gene dosage insufficiencies with potentially lethal collective effect, but strong positive epistasis rooted in the modular structure of cell metabolism cancels it.

    Topological stress triggers persistent DNA lesions in ribosomal DNA with ensuing formation of PML-nucleolar compartment

    Alexandra Urbancokova, Terezie Hornofova ... Pavla Vasicova
    Chemotherapeutics altering DNA topology evoke RNA polymerase I inhibition, rDNA damage and consequent formation of PNAs that segregate persistent rDNA lesions from the active nucleolus, with implications for rDNA maintenance and design of new cancer treatment strategies targeting rDNA repair.

    TRIP13 localizes to synapsed chromosomes and functions as a dosage-sensitive regulator of meiosis

    Jessica Y Chotiner, N Adrian Leu ... P Jeremy Wang
    Mouse TRIP13 localizes to synapsed chromosomal axes and thus exhibits mutually exclusive localization with HORMAD1/HORMAD2, providing a cell biological explanation for dissociation of HORMAD1/2 from chromosomal axes upon synapsis.

    OpenNucleome for high-resolution nuclear structural and dynamical modeling

    Zhuohan Lao, Kartik D Kamat ... Bin Zhang
    An open-source tool for computational simulations of the human genome has been introduced, enabling the characterization of complex nuclear environments and the interpretation of experimental observations.

    SCC3 is an axial element essential for homologous chromosome pairing and synapsis

    Yangzi Zhao, Lijun Ren ... Zhukuan Cheng
    SCC3 not only functions as a member of cohesin complex but also participates in homologous pairing and synapsis during rice meiosis.

    Elimination of subtelomeric repeat sequences exerts little effect on telomere essential functions in Saccharomyces cerevisiae

    Can Hu, Xue-Ting Zhu ... Jin-Qiu Zhou
    Subtelomeric sequences in the yeast S. cerevisiae are dispensable for either cell proliferation or homologous recombination-mediated telomere maintenance in telomerase-null cells, suggesting that these sequences represent remnants of genome evolution.
