    MukB ATPases are regulated independently by the N- and C-terminal domains of MukF kleisin

    Katarzyna Zawadzka et al.
    In Escherichia coli structural maintenance of chromosomes (SMC) complex, MukBEF, a dimeric MukF kleisin binds and activates MukB SMC ATPases through two independent interfaces provided by distinct MukF N- and C-terminal domains.

    The structural basis for dynamic DNA binding and bridging interactions which condense the bacterial centromere

    Gemma LM Fisher et al.
    A combination of structural, biochemical, single-molecule and in vivo methods are used to show how ParB locally condenses the bacterial chromosome near the origin and earmarks this region for segregation.

    Structural snapshots of Xer recombination reveal activation by synaptic complex remodeling and DNA bending

    Aleksandra Bebel et al.
    DNA-bound crystal structures of an essential Xer site-specific recombinase from the bacterium Helicobacter pylori reveal how large conformational changes initiate the untangling of chromosomes upon cell division.

    Transcription dynamically patterns the meiotic chromosome-axis interface

    Xiaoji Sun et al.
    Distributed cohesin rings flexibly tether the axial element structure of meiotic chromosomes to the underlying chromatin to readily accommodate ongoing transcription.

    Meiosis I chromosome segregation is established through regulation of microtubule–kinetochore interactions

    Matthew P Miller et al.
    Preventing premature interactions between microtubules and protein-based structures called kinetochores ensures that chromosomes are segregated by meiosis rather than mitosis in reproductive cells.

    Cohesion is established during DNA replication utilising chromosome associated cohesin rings as well as those loaded de novo onto nascent DNAs

    Madhusudhan Srinivasan et al.
    Sister chromatid cohesion is established during replication by two independent pathways operating in parallel, one converts chromosomal cohesin into cohesive structures while the other loads cohesin onto nascent DNAs.

    DNA sequence encodes the position of DNA supercoils

    Sung Hyun Kim et al.
    Single-molecule experiments reveal that plectonemic supercoils occupy specific positions on DNA and a physical model relates this to the intrinsic curvature, providing an insight into how supercoiling organizes the genome.

    Point of View: Is cell size a spandrel?

    Ariel Amir
    Analysis of experiments on bacteria suggests that the dependence of cell size on growth rate is not an adaptation but a causal consequence of a regulatory mechanism that controls DNA replication.

    Meiosis: Stopping chromosomes from breaking bad

    Rima Sandhu, G Valentin Börner
    The scaffolding that holds chromosome pairs together plays a key role in limiting the levels of double-strand breaks.
