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

    Matthias Karnahl, Misoon Park ... Gerd Jürgens
    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.

    The host exosome pathway underpins biogenesis of the human cytomegalovirus virion

    Declan L Turner, Denis V Korneev ... Rommel A Mathias
    The HCMV virion envelope is derived from the host exosome membrane, and exosome machinery and export pathways facilitate virion egress.

    Flexible utilization of spatial- and motor-based codes for the storage of visuo-spatial information

    Margaret M Henderson, Rosanne L Rademaker, John T Serences
    When human participants are able to plan responses in a visuo-spatial working memory task, sensory-like representations of remembered spatial position in early visual and parietal cortex adaptively trade off with motor-like representations of upcoming actions in sensorimotor cortex.

    Large-scale analysis and computer modeling reveal hidden regularities behind variability of cell division patterns in Arabidopsis thaliana embryogenesis

    Elise Laruelle, Katia Belcram ... Philippe Andrey
    Self-organization based on a feedback loop between cell geometry and division plane positioning plays a central role in the building of tissue architectures in Arabidopsis thaliana embryo through both stereotyped and variable division patterns.

    Dynamic proteomic and phosphoproteomic atlas of corticostriatal axons in neurodevelopment

    Vasin Dumrongprechachan, Ryan B Salisbury ... Yevgenia Kozorovitskiy
    A Cre-dependent reporter mouse line is generated, validated, and used to map cell-type-specific proteome and phosphoproteome of corticostriatal projections across postnatal development.

    Extraction of active RhoGTPases by RhoGDI regulates spatiotemporal patterning of RhoGTPases

    Adriana E Golding, Ilaria Visco ... William M Bement
    Through visualization of directly-labeled RhoGTPase both in vitro and in vivo, RhoGDI is found to spatiotemporally regulate RhoGTPase activity through the extraction of active RhoGTPase.

    The evolution of division of labour in structured and unstructured groups

    Guy Alexander Cooper, Hadleigh Frost ... Stuart Andrew West
    The evolution of division of labour with non-accelerating returns from specialisation can occur for several reasons, including but not limited to topologically constrained group structures, but there must always be a group efficiency benefit and a coordination mechanism is required.

    Fine-tuned repression of Drp1-driven mitochondrial fission primes a ‘stem/progenitor-like state’ to support neoplastic transformation

    Brian Spurlock, Danitra Parker ... Kasturi Mitra
    A mitochondria-based 'priming' of stemness happens by fine-tuned repression of the level or activity of the master regulator of mitochondrial fission, Drp1, which supports carcinogen-induced transformation in a keratinocyte model.

    What do adversarial images tell us about human vision?

    Marin Dujmović, Gaurav Malhotra, Jeffrey S Bowers
    Well-controlled psychological experiments show that there is little overlap in how humans and convolutional networks classify adversarial images, highlighting the problem of using CNNs as models of human vision.

    Delivery of endocytosed proteins to the cell–division plane requires change of pathway from recycling to secretion

    Sandra Richter, Marika Kientz ... Gerd Jürgens
    The same membrane trafficking cargo can change pathways mediated by different members of ARF-GEF family of vesicle formation regulators.
