    The invariant cleavage pattern displayed by ascidian embryos depends on spindle positioning along the cell's longest axis in the apical plane and relies on asynchronous cell divisions

    Rémi Dumollard et al.
    Cell cycle asynchrony regulates apical cell shape to drive cell division orientation in the apical plane.

    Conservation of peripheral nervous system formation mechanisms in divergent ascidian embryos

    Joshua F Coulcher et al.
    Developmental regulatory mechanisms for peripheral nervous system formation appear to be conserved in ascidians despite extensive genomic divergence after 390 MY of separate evolution.

    Divergent mechanisms regulate conserved cardiopharyngeal development and gene expression in distantly related ascidians

    Alberto Stolfi et al.
    Embryos of distantly related sea squirt species are nearly identical but develop according to different gene regulatory mechanisms.

    Co-expression of Foxa.a, Foxd and Fgf9/16/20 defines a transient mesendoderm regulatory state in ascidian embryos

    Clare Hudson et al.
    Ascidian mesendoderm is a transient regulatory state upstream of mesoderm and endoderm gene regulatory networks and required for the initiation of both.

    Parallel visual circuitry in a basal chordate

    Matthew J Kourakis et al.
    The ascidian Ciona integrates visual information from two photoreceptor types through convergent excitatory and disinhibitory circuits, thereby evoking swim behaviors.

    The regulation of oocyte maturation and ovulation in the closest sister group of vertebrates

    Shin Matsubara et al.
    Oocyte maturation and ovulation in the sister group of vertebrates, Ciona intestinalis Type A, are triggered by Ci-VP, the Ciona homolog of a typical neruopeptide, vasopressin.

    The CNS connectome of a tadpole larva of Ciona intestinalis (L.) highlights sidedness in the brain of a chordate sibling

    Kerrianne Ryan et al.
    Serial-section EM analysis uncovers the CNS connectome of a Ciona larva, the second of any entire nervous system, and exposes left-right asymmetries in its synaptic circuits.

    Physical association between a novel plasma-membrane structure and centrosome orients cell division

    Takefumi Negishi et al.
    A newly discovered membrane structure associates with one of the centrioles and affects two important centrosomal events in epidermal cells – ciliary positioning and spindle orientation – through a physical interaction.

    An FGF-driven feed-forward circuit patterns the cardiopharyngeal mesoderm in space and time

    Florian Razy-Krajka et al.
    A gene network for heart versus head muscle specification has been identified in the tunicate Ciona.

    Model for a novel membrane envelope in a filamentous hyperthermophilic virus

    Peter Kasson et al.
    A novel membrane, formed by a monolayer of lipids in a U-shaped conformation, envelops a virus that can withstand extremes of temperature and acidity.
