    Mechanistic insight into a peptide hormone signaling complex mediating floral organ abscission

    Julia Santiago et al.
    A plant peptide hormone controls organ shedding by acting as molecular glue that promotes the interaction between two membrane receptor kinases.

    Temporal integration of auxin information for the regulation of patterning

    Carlos S Galvan-Ampudia et al.
    Rhythmic centrifugal waves of auxin traveling through the tissue provides high definition positional information to cells that is not only spatial but also temporal.

    A stochastic multicellular model identifies biological watermarks from disorders in self-organized patterns of phyllotaxis

    Yassin Refahi et al.
    A stochastic model of phyllotaxis can explain the striking irregularities observed in the spiral patterns of plants and predicts that perturbation patterns provide key information about the underlying biochemical mechanisms.

    A hypothesis on the capacity of plant odorant-binding proteins to bind volatile isoprenoids based on in silico evidences

    Deborah Giordano et al.
    It is hypothesized that volatile organic compounds emitted by plants after stress induction may be sensed by neighboring eavesdropping plants using odorant-binding proteins.

    A terpene synthase-cytochrome P450 cluster in Dictyostelium discoideum produces a novel trisnorsesquiterpene

    Xinlu Chen et al.
    The social amoeba Dictyostelium discoideum employs a terpene synthase-cytochrome P450 metabolic gene cluster to produce a novel trisnorsesquiterpene discodiene.

    Control of plant cell fate transitions by transcriptional and hormonal signals

    Christophe Gaillochet et al.
    HEC transcription factors control the timing of cell fate transitions in a dynamic stem cell system, allowing plants to adapt their developmental program to diverse environments.

    Anisotropic growth is achieved through the additive mechanical effect of material anisotropy and elastic asymmetry

    Firas Bou Daher et al.
    Growing upwards in the young seedling is controlled by two cooperative mechanical mechanisms: cellulose orientation in inner tissues and differential elasticity in epidermal cells.

    Why plants make puzzle cells, and how their shape emerges

    Aleksandra Sapala et al.
    Puzzle-shape cells in the epidermis of many plants form due to a development constraint based on mechanical forces.

    A tension-adhesion feedback loop in plant epidermis

    Stéphane Verger et al.
    Tensile stress patterns in tissues are revealed by cell-cell adhesion defects; in turn, cell responses to supracellular tension require cell-cell adhesion.

    Fluorescent sensors reporting the activity of ammonium transceptors in live cells

    Roberto De Michele et al.
    A modified form of Green Fluorescent Protein integrated into an ammonium transporter provides a sensor that can be used to monitor transport activity in vivo.
