    Arabidopsis 14-3-3 epsilon members contribute to polarity of PIN auxin carrier and auxin transport-related development

    Jutta Keicher et al.
    Conditional genetic inactivation of a highly conserved, ancestral subgroup of 14-3-3 proteins in Arabidopsis thaliana reveals fundamental roles in auxin transport-dependent plant development and post-Golgi trafficking processes.

    Formation of polarity convergences underlying shoot outgrowths

    Katie Abley et al.
    Models that generate tandem alignments of cell polarities are more readily compatible with the formation of PIN1 polarity patterns in plant leaf buds than the most widely accepted “up-the-gradient” model.

    Coordination of tissue cell polarity by auxin transport and signaling

    Carla Verna et al.
    GNOM controls both auxin transport and auxin signaling to coordinate tissue cell polarity during vein patterning in plants.

    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.

    Optogenetic dissection of mitotic spindle positioning in vivo

    Lars-Eric Fielmich et al.
    New germline gene expression, knockout, and optogenetic tools reveal essential roles for Gα-GPR-1,2/Pins as a regulatable membrane anchor and LIN-5/NuMA as an activator of cortical dynein in mitotic spindle positioning.

    Cell type boundaries organize plant development

    Monica Pia Caggiano et al.
    Leaf position, shape and orientation are pre-patterned by cell type boundaries in the shoot meristem.

    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.

    Auxin efflux by PIN-FORMED proteins is activated by two different protein kinases, D6 PROTEIN KINASE and PINOID

    Melina Zourelidou et al.
    Two protein kinases are required to activate auxin efflux transporters from plants.

    Vibrator and PI4KIIIα govern neuroblast polarity by anchoring non-muscle myosin II

    Chwee Tat Koe et al.
    Vibrator and PI4KIIIα that stimulate the synthesis of PI(4)P anchor non-muscle myosin II RLC (Sqh) to the plasma membrane and conversely Sqh associates with PI(4)P and facilitates its membrane localization during asymmetric division of neuroblasts.
