    The manifold actions of signaling peptides on subcellular dynamics of a receptor specify stomatal cell fate

    Xingyun Qi et al.
    A binary cell fate decision to be or not to be stomata is regulated by multiple peptide ligands, each triggering a unique subcellular dynamics of their shared receptor.

    The MADS-box transcription factor PHERES1 controls imprinting in the endosperm by binding to domesticated transposons

    Rita A Batista et al.
    Jumping of transposable elements provides DNA-binding sites for the MADS-box transcription factor PHERES1, allowing the regulation of imprinted genes and other key endosperm development genes.

    Members of the ELMOD protein family specify formation of distinct aperture domains on the Arabidopsis pollen surface

    Yuan Zhou et al.
    Pollen aperture patterning in Arabidopsis is controlled by members of the ELMOD protein family, whose expression levels in developing pollen lineage are tightly regulated.

    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.

    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.

    Spontaneous symbiotic reprogramming of plant roots triggered by receptor-like kinases

    Martina Katharina Ried et al.
    Ectopic expression of Symbiosis Receptor-like Kinase (SYMRK) in roots of the legume Lotus japonicus resulted in spontaneous activation of nodule organogenesis and mycorrhiza-related gene expression in the absence of microbial symbionts or signalling molecules.

    Compensatory sequence variation between trans-species small RNAs and their target sites

    Nathan R Johnson et al.
    Superfamilies of trans-species small RNAs from the parasitic plant Cuscuta have sequence variation that correspond to synonymous site variation in host plant target mRNAs.

    Phosphoprotein SAK1 is a regulator of acclimation to singlet oxygen in Chlamydomonas reinhardtii

    Setsuko Wakao et al.
    SAK1, a novel cytoplasmic phosphoprotein, is a key intermediate component of the retrograde signaling pathway controlling nuclear gene expression during acclimation of Chlamydomonas cells to singlet oxygen stress.

    Proximity labeling of protein complexes and cell-type-specific organellar proteomes in Arabidopsis enabled by TurboID

    Andrea Mair et al.
    Proximity-labeling using engineered biotin ligases TurboID and miniTurbo enables detection of cell-type-specific and low abundance protein complexes and subcellular proteomes in Arabidopsis and other plants.
