  text: The plant hormone auxin is a key regulator of plant growth and development.
    Auxin levels are sensed and interpreted by distinct receptor systems that activate
    a broad range of cellular responses. The Auxin-Binding Protein1 (ABP1) that has
    been identified based on its ability to bind auxin with high affinity is a prime
    candidate for the extracellular receptor responsible for mediating a range of
    auxin effects, in particular, the fast non-transcriptional ones. Contradictory
    genetic studies suggested prominent or no importance of ABP1 in many developmental
    processes. However, how crucial the role of auxin binding to ABP1 is for its functions
    has not been addressed. Here, we show that the auxin-binding pocket of ABP1 is
    essential for its gain-of-function cellular and developmental roles. In total,
    16 different abp1 mutants were prepared that possessed substitutions in the metal
    core or in the hydrophobic amino acids of the auxin-binding pocket as well as
    neutral mutations. Their analysis revealed that an intact auxin-binding pocket
    is a prerequisite for ABP1 to activate downstream components of the ABP1 signalling
    pathway, such as Rho of Plants (ROPs) and to mediate the clathrin association
    with membranes for endocytosis regulation. In planta analyses demonstrated the
    importance of the auxin binding pocket for all known ABP1-mediated postembryonic
    developmental processes, including morphology of leaf epidermal cells, root growth
    and root meristem activity, and vascular tissue differentiation. Taken together,
    these findings suggest that auxin binding to ABP1 is central to its function,
    supporting the role of ABP1 as auxin receptor.

  text: Spatial regulation of the plant hormone indole-3-acetic acid (IAA, or auxin)
    is essential for plant development. Auxin gradient establishment is mediated by
    polarly localized auxin transporters, including PIN-FORMED (PIN) proteins. Their
    localization and abundance at the plasma membrane are tightly regulated by endomembrane
    machinery, especially the endocytic and recycling pathways mediated by the ADP
    ribosylation factor guanine nucleotide exchange factor (ARF-GEF) GNOM. We assessed
    the role of the early secretory pathway in establishing PIN1 polarity in Arabidopsis
    thaliana by pharmacological and genetic approaches. We identified the compound
    endosidin 8 (ES8), which selectively interferes with PIN1 basal polarity without
    altering the polarity of apical proteins. ES8 alters the auxin distribution pattern
    in the root and induces a strong developmental phenotype, including reduced root
    length. The ARF-GEF- defective mutants gnom-like 1 ( gnl1-1) and gnom ( van7)
    are significantly resistant to ES8. The compound does not affect recycling or
    vacuolar trafficking of PIN1 but leads to its intracellular accumulation, resulting
    in loss of PIN1 basal polarity at the plasma membrane. Our data confirm a role
    for GNOM in endoplasmic reticulum (ER) - Golgi trafficking and reveal that a GNL1/GNOM-mediated
    early secretory pathway selectively regulates PIN1 basal polarity establishment
    in a manner essential for normal plant development.

  text: Multiple plant developmental processes, such as lateral root development,
    depend on auxin distribution patterns that are in part generated by the PIN-formed
    family of auxin-efflux transporters. Here we propose that AUXIN RESPONSE FACTOR7
    (ARF7) and the ARF7-regulated FOUR LIPS/MYB124 (FLP) transcription factors jointly
    form a coherent feed-forward motif that mediates the auxin-responsive PIN3 transcription
    in planta to steer the early steps of lateral root formation. This regulatory
    mechanism might endow the PIN3 circuitry with a temporal 'memory' of auxin stimuli,
    potentially maintaining and enhancing the robustness of the auxin flux directionality
    during lateral root development. The cooperative action between canonical auxin
    signalling and other transcription factors might constitute a general mechanism
    by which transcriptional auxin-sensitivity can be regulated at a tissue-specific
    level.

  text: Auxin participates in a multitude of developmental processes, as well as responses
    to environmental cues. Compared with other plant hormones, auxin exhibits a unique
    property, as it undergoes directional, cell-to-cell transport facilitated by plasma
    membrane-localized transport proteins. Among them, a prominent role has been ascribed
    to the PIN family of auxin efflux facilitators. PIN proteins direct polar auxin
    transport on account of their asymmetric subcellular localizations. In this review,
    we provide an overview of the multiple developmental roles of PIN proteins, including
    the atypical endoplasmic reticulum-localized members of the family, and look at
    the family from an evolutionary perspective. Next, we cover the cell biological
    and molecular aspects of PIN function, in particular the establishment of their
    polar subcellular localization. Hormonal and environmental inputs into the regulation
    of PIN action are summarized as well.

  text: In plants, vacuolar H+-ATPase (V-ATPase) activity acidifies both the trans-Golgi
    network/early endosome (TGN/EE) and the vacuole. This dual V-ATPase function has
    impeded our understanding of how the pH homeostasis within the plant TGN/EE controls
    exo- and endocytosis. Here, we show that the weak V-ATPase mutant deetiolated3
    (det3) displayed a pH increase in the TGN/EE, but not in the vacuole, strongly
    impairing secretion and recycling of the brassinosteroid receptor and the cellulose
    synthase complexes to the plasma membrane, in contrast to mutants lacking tonoplast-localized
    V-ATPase activity only. The brassinosteroid insensitivity and the cellulose deficiency
    defects in det3 were tightly correlated with reduced Golgi and TGN/EE motility.
    Thus, our results provide strong evidence that acidification of the TGN/EE, but
    not of the vacuole, is indispensable for functional secretion and recycling in
    plants.

  text: The generation of asymmetry, at both cellular and tissue level, is one of
    the most essential capabilities of all eukaryotic organisms. It mediates basically
    all multicellular development ranging from embryogenesis and de novo organ formation
    till responses to various environmental stimuli. In plants, the awe-inspiring
    number of such processes is regulated by phytohormone auxin and its directional,
    cell-to-cell transport. The mediators of this transport, PIN auxin transporters,
    are asymmetrically localized at the plasma membrane, and this polar localization
    determines the directionality of intercellular auxin flow. Thus, auxin transport
    contributes crucially to the generation of local auxin gradients or maxima, which
    instruct given cell to change its developmental program. Here, we introduce and
    discuss the molecular components and cellular mechanisms regulating the generation
    and maintenance of cellular PIN polarity, as the general hallmarks of cell polarity
    in plants.

  text: To control morphogenesis, molecular regulatory networks have to interfere
    with the mechanical properties of the individual cells of developing organs and
    tissues, but how this is achieved is not well known. We study this issue here
    in the shoot meristem of higher plants, a group of undifferentiated cells where
    complex changes in growth rates and directions lead to the continuous formation
    of new organs [1, 2]. Here, we show that the plant hormone auxin plays an important
    role in this process via a dual, local effect on the extracellular matrix, the
    cell wall, which determines cell shape. Our study reveals that auxin not only
    causes a limited reduction in wall stiffness but also directly interferes with
    wall anisotropy via the regulation of cortical microtubule dynamics. We further
    show that to induce growth isotropy and organ outgrowth, auxin somehow interferes
    with the cortical microtubule-ordering activity of a network of proteins, including
    AUXIN BINDING PROTEIN 1 and KATANIN 1. Numerical simulations further indicate
    that the induced isotropy is sufficient to amplify the effects of the relatively
    minor changes in wall stiffness to promote organogenesis and the establishment
    of new growth axes in a robust manner.

  text: The prominent and evolutionarily ancient role of the plant hormone auxin is
    the regulation of cell expansion. Cell expansion requires ordered arrangement
    of the cytoskeleton but molecular mechanisms underlying its regulation by signalling
    molecules including auxin are unknown. Here we show in the model plant Arabidopsis
    thaliana that in elongating cells exogenous application of auxin or redistribution
    of endogenous auxin induces very rapid microtubule re-orientation from transverse
    to longitudinal, coherent with the inhibition of cell expansion. This fast auxin
    effect requires auxin binding protein 1 (ABP1) and involves a contribution of
    downstream signalling components such as ROP6 GTPase, ROP-interactive protein
    RIC1 and the microtubule-severing protein katanin. These components are required
    for rapid auxin-and ABP1-mediated re-orientation of microtubules to regulate cell
    elongation in roots and dark-grown hypocotyls as well as asymmetric growth during
    gravitropic responses.

  text: Phosphatidylinositol (PtdIns) is a structural phospholipid that can be phosphorylated
    into various lipid signaling molecules, designated polyphosphoinositides (PPIs).
    The reversible phosphorylation of PPIs on the 3, 4, or 5 position of inositol
    is performed by a set of organelle-specific kinases and phosphatases, and the
    characteristic head groups make these molecules ideal for regulating biological
    processes in time and space. In yeast and mammals, PtdIns3P and PtdIns(3,5)P2
    play crucial roles in trafficking toward the lytic compartments, whereas the role
    in plants is not yet fully understood. Here we identified the role of a land plant-specific
    subgroup of PPI phosphatases, the suppressor of actin 2 (SAC2) to SAC5, during
    vacuolar trafficking and morphogenesis in Arabidopsis thaliana. SAC2-SAC5 localize
    to the tonoplast along with PtdIns3P, the presumable product of their activity.
    In SAC gain- and loss-of-function mutants, the levels of PtdIns monophosphates
    and bisphosphates were changed, with opposite effects on the morphology of storage
    and lytic vacuoles, and the trafficking toward the vacuoles was defective. Moreover,
    multiple sac knockout mutants had an increased number of smaller storage and lytic
    vacuoles, whereas extralarge vacuoles were observed in the overexpression lines,
    correlating with various growth and developmental defects. The fragmented vacuolar
    phenotype of sac mutants could be mimicked by treating wild-type seedlings with
    PtdIns(3,5)P2, corroborating that this PPI is important for vacuole morphology.
    Taken together, these results provide evidence that PPIs, together with their
    metabolic enzymes SAC2-SAC5, are crucial for vacuolar trafficking and for vacuolar
    morphology and function in plants.

  text: GNOM is one of the most characterized membrane trafficking regulators in plants,
    with crucial roles in development. GNOM encodes an ARF-guanine nucleotide exchange
    factor (ARF-GEF) that activates small GTPases of the ARF (ADP ribosylation factor)
    class to mediate vesicle budding at endomembranes. The crucial role of GNOM in
    recycling of PIN auxin transporters and other proteins to the plasma membrane
    was identified in studies using the ARF-GEF inhibitor brefeldin A (BFA). GNOM,
    the most prominent regulator of recycling in plants, has been proposed to act
    and localize at so far elusive recycling endosomes. Here, we report the GNOM localization
    in context of its cellular function in Arabidopsis thaliana. State-of-the-art
    imaging, pharmacological interference, and ultrastructure analysis show that GNOM
    predominantly localizes to Golgi apparatus. Super-resolution confocal live imaging
    microscopy identified GNOM and its closest homolog GNOM-like 1 at distinct subdomains
    on Golgi cisternae. Short-term BFA treatment stabilizes GNOM at the Golgi apparatus,
    whereas prolonged exposures results in GNOM translocation to trans-Golgi network
    (TGN)/early endosomes (EEs). Malformed TGN/EE in gnom mutants suggests a role
    for GNOM in maintaining TGN/EE function. Our results redefine the subcellular
    action of GNOM and reevaluate the identity and function of recycling endosomes
    in plants.

  text: In plants, the patterning of stem cell-enriched meristems requires a graded
    auxin response maximum that emerges from the concerted action of polar auxin transport,
    auxin biosynthesis, auxin metabolism, and cellular auxin response machinery. However,
    mechanisms underlying this auxin response maximum-mediated root stem cell maintenance
    are not fully understood. Here, we present unexpected evidence that WUSCHEL-RELATED
    HOMEOBOX 5 (WOX5) transcription factor modulates expression of auxin biosynthetic
    genes in the quiescent center (QC) of the root and thus provides a robust mechanism
    for the maintenance of auxin response maximum in the root tip. This WOX5 action
    is balanced through the activity of indole-3-acetic acid 17 (IAA17) auxin response
    repressor. Our combined genetic, cell biology, and computational modeling studies
    revealed a previously uncharacterized feedback loop linking WOX5-mediated auxin
    production to IAA17-dependent repression of auxin responses. This WOX5-IAA17 feedback
    circuit further assures the maintenance of auxin response maximum in the root
    tip and thereby contributes to the maintenance of distal stem cell (DSC) populations.
    Our experimental studies and in silico computer simulations both demonstrate that
    the WOX5-IAA17 feedback circuit is essential for the maintenance of auxin gradient
    in the root tip and the auxin-mediated root DSC differentiation.

  text: Targeting membrane proteins for degradation requires the sequential action
    of ESCRT sub-complexes ESCRT-0 to ESCRT-III. Although this machinery is generally
    conserved among kingdoms, plants lack the essential ESCRT-0 components. A new
    report closes this gap by identifying a novel protein family that substitutes
    for ESCRT-0 function in plants.

  text: ROPs (Rho of plants) belong to a large family of plant-specific Rho-like small
    GTPases that function as essential molecular switches to control diverse cellular
    processes including cytoskeleton organization, cell polarization, cytokinesis,
    cell differentiation and vesicle trafficking. Although the machineries of vesicle
    trafficking and cell polarity in plants have been individually well addressed,
    how ROPs co-ordinate those processes is still largely unclear. Recent progress
    has been made towards an understanding of the coordination of ROP signalling and
    trafficking of PIN (PINFORMED) transporters for the plant hormone auxin in both
    root and leaf pavement cells. PIN transporters constantly shuttle between the
    endosomal compartments and the polar plasma membrane domains, therefore the modulation
    of PIN-dependent auxin transport between cells is a main developmental output
    of ROP-regulated vesicle trafficking. The present review focuses on these cellular
    mechanisms, especially the integration of ROP-based vesicle trafficking and plant
    cell polarity.

  text: Auxin-binding protein 1 (ABP1) was discovered nearly 40 years ago and was
    shown to be essential for plant development and morphogenesis, but its mode of
    action remains unclear. Here, we report that the plasma membrane-localized transmembrane
    kinase (TMK) receptor-like kinases interact with ABP1 and transduce auxin signal
    to activate plasma membrane-associated ROPs [Rho-like guanosine triphosphatases
    (GTPase) from plants], leading to changes in the cytoskeleton and the shape of
    leaf pavement cells in Arabidopsis. The interaction between ABP1 and TMK at the
    cell surface is induced by auxin and requires ABP1 sensing of auxin. These findings
    show that TMK proteins and ABP1 form a cell surface auxin perception complex that
    activates ROP signaling pathways, regulating nontranscriptional cytoplasmic responses
    and associated fundamental processes.

  text: Cell polarity manifested by asymmetric distribution of cargoes, such as receptors
    and transporters, within the plasma membrane (PM) is crucial for essential functions
    in multicellular organisms. In plants, cell polarity (re)establishment is intimately
    linked to patterning processes. Despite the importance of cell polarity, its underlying
    mechanisms are still largely unknown, including the definition and distinctiveness
    of the polar domains within the PM. Here, we show in Arabidopsis thaliana that
    the signaling membrane components, the phosphoinositides phosphatidylinositol
    4-phosphate (PtdIns4P) and phosphatidylinositol 4, 5-bisphosphate [PtdIns(4, 5)P2]
    as well as PtdIns4P 5-kinases mediating their interconversion, are specifically
    enriched at apical and basal polar plasma membrane domains. The PtdIns4P 5-kinases
    PIP5K1 and PIP5K2 are redundantly required for polar localization of specifically
    apical and basal cargoes, such as PIN-FORMED transporters for the plant hormone
    auxin. As a consequence of the polarity defects, instructive auxin gradients as
    well as embryonic and postembryonic patterning are severely compromised. Furthermore,
    auxin itself regulates PIP5K transcription and PtdIns4P and PtdIns(4, 5)P2 levels,
    in particular their association with polar PM domains. Our results provide insight
    into the polar domain-delineating mechanisms in plant cells that depend on apical
    and basal distribution of membrane lipids and are essential for embryonic and
    postembryonic patterning.

  text: Stomata are two-celled valves that control epidermal pores whose spacing optimizes
    shoot-atmosphere gas exchange. They develop from protodermal cells after unequal
    divisions followed by an equal division and differentiation. The concentration
    of the hormone auxin, a master plant developmental regulator, is tightly controlled
    in time and space, but its role, if any, in stomatal formation is obscure. Here
    dynamic changes of auxin activity during stomatal development are monitored using
    auxin input (DII-VENUS) and output (DR5:VENUS) markers by time-lapse imaging.
    A decrease in auxin levels in the smaller daughter cell after unequal division
    presages the acquisition of a guard mother cell fate whose equal division produces
    the two guard cells. Thus, stomatal patterning requires auxin pathway control
    of stem cell compartment size, as well as auxin depletion that triggers a developmental
    switch from unequal to equal division.

  text: The plant hormones auxin and cytokinin mutually coordinate their activities
    to control various aspects of development [1-9], and their crosstalk occurs at
    multiple levels [10, 11]. Cytokinin-mediated modulation of auxin transport provides
    an efficient means to regulate auxin distribution in plant organs. Here, we demonstrate
    that cytokinin does not merely control the overall auxin flow capacity, but might
    also act as a polarizing cue and control the auxin stream directionality during
    plant organogenesis. Cytokinin enhances the PIN-FORMED1 (PIN1) auxin transporter
    depletion at specific polar domains, thus rearranging the cellular PIN polarities
    and directly regulating the auxin flow direction. This selective cytokinin sensitivity
    correlates with the PIN protein phosphorylation degree. PIN1 phosphomimicking
    mutations, as well as enhanced phosphorylation in plants with modulated activities
    of PIN-specific kinases and phosphatases, desensitize PIN1 to cytokinin. Our results
    reveal conceptually novel, cytokinin-driven polarization mechanism that operates
    in developmental processes involving rapid auxin stream redirection, such as lateral
    root organogenesis, in which a gradual PIN polarity switch defines the growth
    axis of the newly formed organ.

  text: The emergence and radiation of multicellular land plants was driven by crucial
    innovations to their body plans [1]. The directional transport of the phytohormone
    auxin represents a key, plant-specific mechanism for polarization and patterning
    in complex seed plants [2-5]. Here, we show that already in the early diverging
    land plant lineage, as exemplified by the moss Physcomitrella patens, auxin transport
    by PIN transporters is operational and diversified into ER-localized and plasma
    membrane-localized PIN proteins. Gain-of-function and loss-of-function analyses
    revealed that PIN-dependent intercellular auxin transport in Physcomitrella mediates
    crucial developmental transitions in tip-growing filaments and waves of polarization
    and differentiation in leaf-like structures. Plasma membrane PIN proteins localize
    in a polar manner to the tips of moss filaments, revealing an unexpected relation
    between polarization mechanisms in moss tip-growing cells and multicellular tissues
    of seed plants. Our results trace the origins of polarization and auxin-mediated
    patterning mechanisms and highlight the crucial role of polarized auxin transport
    during the evolution of multicellular land plants.

  text: Auxin polar transport, local maxima, and gradients have become an importantmodel
    system for studying self-organization. Auxin distribution is regulated by auxin-dependent
    positive feedback loops that are not well-understood at the molecular level. Previously,
    we showed the involvement of the RHO of Plants (ROP) effector INTERACTOR of CONSTITUTIVELY
    active ROP 1 (ICR1) in regulation of auxin transport and that ICR1 levels are
    posttranscriptionally repressed at the site of maximum auxin accumulation at the
    root tip. Here, we show that bimodal regulation of ICR1 levels by auxin is essential
    for regulating formation of auxin local maxima and gradients. ICR1 levels increase
    concomitant with increase in auxin response in lateral root primordia, cotyledon
    tips, and provascular tissues. However, in the embryo hypophysis and root meristem,
    when auxin exceeds critical levels, ICR1 is rapidly destabilized by an SCF(TIR1/AFB)
    [SKP, Cullin, F-box (transport inhibitor response 1/auxin signaling F-box protein)]-dependent
    auxin signaling mechanism. Furthermore, ectopic expression of ICR1 in the embryo
    hypophysis resulted in reduction of auxin accumulation and concomitant root growth
    arrest. ICR1 disappeared during root regeneration and lateral root initiation
    concomitantly with the formation of a local auxin maximum in response to external
    auxin treatments and transiently after gravitropic stimulation. Destabilization
    of ICR1 was impaired after inhibition of auxin transport and signaling, proteasome
    function, and protein synthesis. A mathematical model based on these findings
    shows that an in vivo-like auxin distribution, rootward auxin flux, and shootward
    reflux can be simulated without assuming preexisting tissue polarity. Our experimental
    results and mathematical modeling indicate that regulation of auxin distribution
    is tightly associated with auxin-dependent ICR1 levels.

  text: 'Development of cambium and its activity is important for our knowledge of
    the mechanism of secondary growth. Arabidopsis thaliana emerges as a good model
    plant for such a kind of study. Thus, this paper reports on cellular events taking
    place in the interfascicular regions of inflorescence stems of A. thaliana, leading
    to the development of interfascicular cambium from differentiated interfascicular
    parenchyma cells (IPC). These events are as follows: appearance of auxin accumulation,
    PIN1 gene expression, polar PIN1 protein localization in the basal plasma membrane
    and periclinal divisions. Distribution of auxin was observed to be higher in differentiating
    into cambium parenchyma cells compared to cells within the pith and cortex. Expression
    of PIN1 in IPC was always preceded by auxin accumulation. Basal localization of
    PIN1 was already established in the cells prior to their periclinal division.
    These cellular events initiated within parenchyma cells adjacent to the vascular
    bundles and successively extended from that point towards the middle region of
    the interfascicular area, located between neighboring vascular bundles. The final
    consequence of which was the closure of the cambial ring within the stem. Changes
    in the chemical composition of IPC walls were also detected and included changes
    of pectic epitopes, xyloglucans (XG) and extensins rich in hydroxyproline (HRGPs).
    In summary, results presented in this paper describe interfascicular cambium ontogenesis
    in terms of successive cellular events in the interfascicular regions of inflorescence
    stems of Arabidopsis.'
