    A chloroplast retrograde signal, 3’-phosphoadenosine 5’-phosphate, acts as a secondary messenger in abscisic acid signaling in stomatal closure and germination

    Wannarat Pornsiriwong et al.
    Molecular signals from chloroplasts can synergistically interact with the plant hormone, abscisic acid (ABA), to regulate non-canonical signaling pathways mediating fundamental cellular processes including stomatal closure, seed dormancy and germination.

    Autocrine regulation of stomatal differentiation potential by EPF1 and ERECTA-LIKE1 ligand-receptor signaling

    Xingyun Qi et al.
    The stomatal precursor cell uses autocrine peptide-receptor kinase signaling to self-inhibit its differentiation potential in order to ensure proper stomatal development on the plant epidermis.

    Irreversible fate commitment in the Arabidopsis stomatal lineage requires a FAMA and RETINOBLASTOMA-RELATED module

    Juliana L Matos et al.
    An adult stem-cell lineage terminally differentiates via recruitment of the RETINOBLASTOMA-RELATED protein by a lineage specific transcription factor.

    The Gastric Network: How the stomach and the brain work together at rest

    Giuseppina Porciello et al.
    Low-frequency electrical waves in the stomach seem to be synchronised with the activity of a newly discovered resting-state network in the human brain.

    Fungal effector Ecp6 outcompetes host immune receptor for chitin binding through intrachain LysM dimerization

    Andrea Sánchez-Vallet et al.
    Structural and biochemical analysis of a protein called Ecp6, which is produced by a tomato fungus, reveals how the protein prevents plants from launching an immune response to the chitin in fungal cell walls.

    Stomach-brain synchrony reveals a novel, delayed-connectivity resting-state network in humans

    Ignacio Rebollo et al.
    Coupling between the gastric rhythm and brain activity at rest reveals a novel resting-state network, characterized by delayed functional connectivity.

    The carcinine transporter CarT is required in Drosophila photoreceptor neurons to sustain histamine recycling

    Drew Stenesen et al.
    Fly vision depends on a member of the SLC22 transporter family for recycling the histamine neurotransmitter following its uptake by glia and its modification into the transport metabolite carcinine.

    MorphoGraphX: A platform for quantifying morphogenesis in 4D

    Pierre Barbier de Reuille et al.
    MorphoGraphX summarizes full 3D datasets as curved surface images (2.5D), enabling the efficient quantification of growth and gene expression data from large time-lapse volumetric datasets.

    Calcium specificity signaling mechanisms in abscisic acid signal transduction in Arabidopsis guard cells

    Benjamin Brandt et al.
    The calcium-dependent signaling pathway during ABA-dependent stomatal closure requires the calcium-independent pathway, and calcium signaling specificity is mediated by PP2C protein phosphatases.
