    The RhoGAP activity of CYK-4/MgcRacGAP functions non-canonically by promoting RhoA activation during cytokinesis

    Donglei Zhang, Michael Glotzer
    Activation of the key regulator of cytokinesis, RhoA, involves an unexpected contribution by a RhoGAP domain.

    Cytokinin transfer by a free-living mirid to Nicotiana attenuata recapitulates a strategy of endophytic insects

    Christoph Brütting et al.
    Cytokinin-dependent manipulation of plant metabolism is a strategy employed not only by gallers and leaf-miners but also by a free-living insect, Tupiocoris notatus, which directly transfers cytokinins at feeding sites to manipulate its host plant.

    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.

    Cytokinesis in vertebrate cells initiates by contraction of an equatorial actomyosin network composed of randomly oriented filaments

    Felix Spira et al.
    Asymmetric tension increase along the cell equator promotes self-organization of actomyosin into a partially aligned network during cytokinetic cleavage furrow ingression of vertebrate cells.

    ER assembly of SNARE complexes mediating formation of partitioning membrane in Arabidopsis cytokinesis

    Matthias Karnahl et al.
    SNARE proteins are delivered as complexes already from the endoplasmic reticulum along the secretory pathway to the cell division plane to mediate the formation of the partitioning membrane by vesicle fusion.

    T cells translate individual, quantal activation into collective, analog cytokine responses via time-integrated feedbacks

    Karen E Tkach et al.
    Experiment-driven quantitative model of IL-2 secretion demonstrates how T cells integrate their digital antigen responses into an analog-scaled output.

    A positive-feedback-based mechanism for constriction rate acceleration during cytokinesis in Caenorhabditis elegans

    Renat N Khaliullin et al.
    Positive feedback between contractile ring myosin and compression-driven cortical flow can explain the exponential accumulation of contractile ring components and constriction rate acceleration that ensures timely cell separation during cytokinesis.

    Cell-intrinsic and -extrinsic mechanisms promote cell-type-specific cytokinetic diversity

    Tim Davies et al.
    Functional molecular analysis of cytokinesis in Caenorhabditis elegans four-cell embryos reveals cell-type-specific variation in the fundamental dependence on a robust f-actin cytoskeleton for successful cell division, mediated by both cell-intrinsic and -extrinsic pathways.
