    Cross-species functional diversity within the PIN auxin efflux protein family

    Devin Lee O'Connor et al.
    Comparative genetics between distant plant species shows that for the PIN auxin transport proteins differential membrane and tissue-level accumulation, transport activity, and interaction result in different functional properties in the shoot post transcription.

    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.

    Mechano-dependent signaling by Latrophilin/CIRL quenches cAMP in proprioceptive neurons

    Nicole Scholz et al.

    A digital 3D reference atlas reveals cellular growth patterns shaping the Arabidopsis ovule

    Athul Vijayan et al.
    Deep imaging, machine-learning-based segmentation, and tissue annotation resulted in a developmental series of 3D digital ovules with cellular resolution allowing next-level analysis of the ontogenesis of this complex organ.

    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.

    Radially patterned cell behaviours during tube budding from an epithelium

    Yara E Sanchez-Corrales et al.
    Quantitative analysis in quasi-3D reveals apically driven cell behaviours that are closely coordinated across the tissue to allow ordered tube invagination through a focal point.

    Selective amputation of the pharynx identifies a FoxA-dependent regeneration program in planaria

    Carolyn E Adler et al.
    A chemical method has been developed for studying single organ regeneration and fate specification of stem cells in an adult organism.

    Auxin-regulated chromatin switch directs acquisition of flower primordium founder fate

    Miin-Feng Wu et al.
    SWI/SNF chromatin remodeling complexes act as ‘gatekeepers’ for auxin responses and directly interact with the auxin response factor MONOPTEROS.
