    Two mechanisms regulate directional cell growth in Arabidopsis lateral roots

    Charlotte Kirchhelle et al.
    In lateral roots, cells employ a novel pathway to cell edges to control directional growth, which acts independently of the leading paradigm of oriented deposition of cellulose microfibrils at faces.

    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.

    Mechanism of bidirectional thermotaxis in Escherichia coli

    Anja Paulick et al.
    The interplay between the opposing responses mediated by different chemoreceptors enables bacteria to swim towards a preferred temperature.

    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.

    GLO-Roots: an imaging platform enabling multidimensional characterization of soil-grown root systems

    Rubén Rellán-Álvarez et al.
    A luminescence-based imaging system is presented that allows soil-based environmental stimuli to be studied in root systems under physiologically relevant conditions.

    KATANIN-dependent mechanical properties of the stigmatic cell wall mediate the pollen tube path in Arabidopsis

    Lucie Riglet et al.
    KATANIN1 in stigma papilla cells prevents disordered pollen tube growth and straightens pollen tube direction, allowing the pollen tube to find its correct path to the underlying female tissues.

    Co-regulation and function of FOXM1/RHNO1 bidirectional genes in cancer

    Carter J Barger et al.
    FOXM1 is co-expressed with its bidirectional gene partner RHNO1, and the two genes promote DNA repair, cell growth and survival, and chemotherapy resistance in ovarian cancer.

    Theoretical tool bridging cell polarities with development of robust morphologies

    Silas Boye Nissen et al.
    Biological shapes and morphological transitions can emerge from combining directed interactions between cells with apical-basal and planar cell polarity.
