    Negative regulation of conserved RSL class I bHLH transcription factors evolved independently among land plants

    Suvi Honkanen et al.
    An ancient and conserved genetic mechanism for cell differentiation is under distinct negative regulation in different lineages of land plants.

    The Arabidopsis V-ATPase is localized to the TGN/EE via a seed plant-specific motif

    Upendo Lupanga et al.
    Analysis of the Arabidopsis V-ATPase reveals convergent evolution of differential targeting as well as redundancy of the endosomal and vacuolar isoforms during vegetative development.

    Origin and evolution of the nuclear auxin response system

    Sumanth K Mutte et al.
    The system that controls gene expression by the plant signaling molecule auxin has deep evolutionary roots, and stepwise increases in system complexity shaped the highly diverse auxin response in land plants.

    LEAFY maintains apical stem cell activity during shoot development in the fern Ceratopteris richardii 

    Andrew RG Plackett et al.
    Transgenic analysis reveals a role for LEAFY in ferns that supports a trajectory from general to floral meristem-specific function as land plants evolved.

    Constitutive auxin response in Physcomitrella reveals complex interactions between Aux/IAA and ARF proteins

    Meirav Lavy et al.
    The auxin-sensitive Aux/IAA transcriptional repressors regulate approximately 35% of the annotated genes in Physcomitrella patens and exhibit complex interactions with both the activating and repressing ARF transcription factors.

    Parallel global profiling of plant TOR dynamics reveals a conserved role for LARP1 in translation

    M Regina Scarpin et al.
    Plants and humans use a shared mechanism, the eukaryotic metabolic sensor TARGET OF RAPAMYCIN protein kinase and its substrate, an RNA-binding protein called LARP1, to coordinate post-transcriptional gene expression.
