  text: The primary cell wall is a fundamental plant constituent that is flexible
    but sufficiently rigid to support the plant cell shape. Although many studies
    have demonstrated that reactive oxygen species (ROS) serve as important signaling
    messengers to modify the cell wall structure and affect cellular growth, the regulatory
    mechanism underlying the spatial-temporal regulation of ROS activity for cell
    wall maintenance remains largely unclear. Here, we demonstrate the role of the
    Arabidopsis (Arabidopsis thaliana) multicopper oxidase-like protein skewed 5 (SKU5)
    and its homolog SKU5-similar 1 (SKS1) in root cell wall formation through modulating
    ROS homeostasis. Loss of SKU5 and SKS1 function resulted in aberrant division
    planes, protruding cell walls, ectopic deposition of iron, and reduced nicotinamide
    adeninedinucleotide phosphate (NADPH) oxidase-dependent ROS overproduction in
    the root epidermis–cortex and cortex–endodermis junctions. A decrease in ROS level
    or inhibition of NADPH oxidase activity rescued the cell wall defects of sku5
    sks1 double mutants. SKU5 and SKS1 proteins were activated by iron treatment,
    and iron over-accumulated in the walls between the root epidermis and cortex cell
    layers of sku5 sks1. The glycosylphosphatidylinositol-anchored motif was crucial
    for membrane association and functionality of SKU5 and SKS1. Overall, our results
    identified SKU5 and SKS1 as regulators of ROS at the cell surface for regulation
    of cell wall structure and root cell growth.

  text: The quality control system for messenger RNA (mRNA) is fundamental for cellular
    activities in eukaryotes. To elucidate the molecular mechanism of 3'-Phosphoinositide-Dependent
    Protein Kinase1 (PDK1), a master regulator that is essential throughout eukaryotic
    growth and development, we employed a forward genetic approach to screen for suppressors
    of the loss-of-function T-DNA insertion double mutant pdk1.1 pdk1.2 in Arabidopsis
    thaliana. Notably, the severe growth attenuation of pdk1.1 pdk1.2 was rescued
    by sop21 (suppressor of pdk1.1 pdk1.2), which harbours a loss-of-function mutation
    in PELOTA1 (PEL1). PEL1 is a homologue of mammalian PELOTA and yeast (Saccharomyces
    cerevisiae) DOM34p, which each form a heterodimeric complex with the GTPase HBS1
    (HSP70 SUBFAMILY B SUPPRESSOR1, also called SUPERKILLER PROTEIN7, SKI7), a protein
    that is responsible for ribosomal rescue and thereby assures the quality and fidelity
    of mRNA molecules during translation. Genetic analysis further revealed that a
    dysfunctional PEL1-HBS1 complex failed to degrade the T-DNA-disrupted PDK1 transcripts,
    which were truncated but functional, and thus rescued the growth and developmental
    defects of pdk1.1 pdk1.2. Our studies demonstrated the functionality of a homologous
    PELOTA-HBS1 complex and identified its essential regulatory role in plants, providing
    insights into the mechanism of mRNA quality control.

  text: "The phytohormone auxin and its directional transport through tissues are
    intensively studied. However, a mechanistic understanding of auxin-mediated feedback
    on endocytosis and polar distribution of PIN auxin transporters remains limited
    due to contradictory observations and interpretations. Here, we used state-of-the-art
    methods to reexamine the\r\nauxin effects on PIN endocytic trafficking. We used
    high auxin concentrations or longer treatments versus lower concentrations and
    shorter treatments of natural (IAA) and synthetic (NAA) auxins to distinguish
    between specific and nonspecific effects. Longer treatments of both auxins interfere
    with Brefeldin A-mediated intracellular PIN2 accumulation and also with general
    aggregation of endomembrane compartments. NAA treatment decreased the internalization
    of the endocytic tracer dye, FM4-64; however, NAA treatment also affected the
    number, distribution, and compartment identity of the early endosome/trans-Golgi
    network (EE/TGN), rendering the FM4-64 endocytic assays at high NAA concentrations
    unreliable. To circumvent these nonspecific effects of NAA and IAA affecting the
    endomembrane system, we opted for alternative approaches visualizing the endocytic
    events directly at the plasma membrane (PM). Using Total Internal Reflection Fluorescence
    (TIRF) microscopy, we saw no significant effects of IAA or NAA treatments on the
    incidence and dynamics of clathrin foci, implying that these treatments do not
    affect the overall endocytosis rate. However, both NAA and IAA at low concentrations
    rapidly and specifically promoted endocytosis of photo-converted PIN2 from the
    PM. These analyses identify a specific effect of NAA and IAA on PIN2 endocytosis,
    thus contributing to its\r\npolarity maintenance and furthermore illustrate that
    high auxin levels have nonspecific effects on trafficking and endomembrane compartments. "

  text: The TPLATE complex (TPC) is a key endocytic adaptor protein complex in plants.
    TPC in Arabidopsis (Arabidopsis thaliana) contains six evolutionarily conserved
    subunits and two plant-specific subunits, AtEH1/Pan1 and AtEH2/Pan1, although
    cytoplasmic proteins are not associated with the hexameric subcomplex in the cytoplasm.
    To investigate the dynamic assembly of the octameric TPC at the plasma membrane
    (PM), we performed state-of-the-art dual-color live cell imaging at physiological
    and lowered temperatures. Lowering the temperature slowed down endocytosis, thereby
    enhancing the temporal resolution of the differential recruitment of endocytic
    components. Under both normal and lowered temperature conditions, the core TPC
    subunit TPLATE and the AtEH/Pan1 proteins exhibited simultaneous recruitment at
    the PM. These results, together with co-localization analysis of different TPC
    subunits, allow us to conclude that TPC in plant cells is not recruited to the
    PM sequentially but as an octameric complex.

  text: Plants have a remarkable capacity to adjust their growth and development to
    elevated ambient temperatures. Increased elongation growth of roots, hypocotyls
    and petioles in warm temperatures are hallmarks of seedling thermomorphogenesis.
    In the last decade, significant progress has been made to identify the molecular
    signaling components regulating these growth responses. Increased ambient temperature
    utilizes diverse components of the light sensing and signal transduction network
    to trigger growth adjustments. However, it remains unknown whether temperature
    sensing and responses are universal processes that occur uniformly in all plant
    organs. Alternatively, temperature sensing may be confined to specific tissues
    or organs, which would require a systemic signal that mediates responses in distal
    parts of the plant. Here we show that Arabidopsis (Arabidopsis thaliana) seedlings
    show organ-specific transcriptome responses to elevated temperatures, and that
    thermomorphogenesis involves both autonomous and organ-interdependent temperature
    sensing and signaling. Seedling roots can sense and respond to temperature in
    a shoot-independent manner, whereas shoot temperature responses require both local
    and systemic processes. The induction of cell elongation in hypocotyls requires
    temperature sensing in cotyledons, followed by generation of a mobile auxin signal.
    Subsequently, auxin travels to the hypocotyl where it triggers local brassinosteroid-induced
    cell elongation in seedling stems, which depends upon a distinct, permissive temperature
    sensor in the hypocotyl.

  text: Polar auxin transport plays a pivotal role in plant growth and development.
    PIN auxin efflux carriers regulate directional auxin movement by establishing
    local auxin maxima, minima, and gradients that drive multiple developmental processes
    and responses to environmental signals. Auxin has been proposed to modulate its
    own transport by regulating subcellular PIN trafficking via processes such as
    clathrin-mediated PIN endocytosis and constitutive recycling. Here, we further
    investigated the mechanisms by which auxin affects PIN trafficking by screening
    auxin analogs and identified pinstatic acid (PISA) as a positive modulator of
    polar auxin transport in Arabidopsis thaliana. PISA had an auxin-like effect on
    hypocotyl elongation and adventitious root formation via positive regulation of
    auxin transport. PISA did not activate SCFTIR1/AFB signaling and yet induced PIN
    accumulation at the cell surface by inhibiting PIN internalization from the plasma
    membrane. This work demonstrates PISA to be a promising chemical tool to dissect
    the regulatory mechanisms behind subcellular PIN trafficking and auxin transport.

  text: Auxin steers numerous physiological processes in plants, making the tight
    control of its endogenous levels and spatiotemporal distribution a necessity.
    This regulation is achieved by different mechanisms, including auxin biosynthesis,
    metabolic conversions, degradation, and transport. Here, we introduce cis-cinnamic
    acid (c-CA) as a novel and unique addition to a small group of endogenous molecules
    affecting in planta auxin concentrations. c-CA is the photo-isomerization product
    of the phenylpropanoid pathway intermediate trans-CA (t-CA). When grown on c-CA-containing
    medium, an evolutionary diverse set of plant species were shown to exhibit phenotypes
    characteristic for high auxin levels, including inhibition of primary root growth,
    induction of root hairs, and promotion of adventitious and lateral rooting. By
    molecular docking and receptor binding assays, we showed that c-CA itself is neither
    an auxin nor an anti-auxin, and auxin profiling data revealed that c-CA does not
    significantly interfere with auxin biosynthesis. Single cell-based auxin accumulation
    assays showed that c-CA, and not t-CA, is a potent inhibitor of auxin efflux.
    Auxin signaling reporters detected changes in spatiotemporal distribution of the
    auxin response along the root of c-CA-treated plants, and long-distance auxin
    transport assays showed no inhibition of rootward auxin transport. Overall, these
    results suggest that the phenotypes of c-CA-treated plants are the consequence
    of a local change in auxin accumulation, induced by the inhibition of auxin efflux.
    This work reveals a novel mechanism how plants may regulate auxin levels and adds
    a novel, naturally occurring molecule to the chemical toolbox for the studies
    of auxin homeostasis.

  text: 'The exocyst, a eukaryotic tethering complex, coregulates targeted exocytosis
    as an effector of small GTPases in polarized cell growth. In land plants, several
    exocyst subunits are encoded by double or triple paralogs, culminating in tens
    of EXO70 paralogs. Out of 23 Arabidopsis thaliana EXO70 isoforms, we analyzed
    seven isoforms expressed in pollen. Genetic and microscopic analyses of single
    mutants in EXO70A2, EXO70C1, EXO70C2, EXO70F1, EXO70H3, EXO70H5, and EXO70H6 genes
    revealed that only a loss-of-function EXO70C2 allele resulted in a significant
    male-specific transmission defect (segregation 40%:51%:9%) due to aberrant pollen
    tube growth. Mutant pollen tubes grown in vitro exhibited an enhanced growth rate
    and a decreased thickness of the tip cell wall, causing tip bursts. However, exo70C2
    pollen tubes could frequently recover and restart their speedy elongation, resulting
    in a repetitive stop-and-go growth dynamics. A pollenspecific depletion of the
    closest paralog, EXO70C1, using artificial microRNA in the exo70C2 mutant background,
    resulted in a complete pollen-specific transmission defect, suggesting redundant
    functions of EXO70C1 and EXO70C2. Both EXO70C1 and EXO70C2, GFP tagged and expressed
    under the control of their native promoters, localized in the cytoplasm of pollen
    grains, pollen tubes, and also root trichoblast cells. The expression of EXO70C2-GFP
    complemented the aberrant growth of exo70C2 pollen tubes. The absent EXO70C2 interactions
    with core exocyst subunits in the yeast two-hybrid assay, cytoplasmic localization,
    and genetic effect suggest an unconventional EXO70 function possibly as a regulator
    of exocytosis outside the exocyst complex. In conclusion, EXO70C2 is a novel factor
    contributing to the regulation of optimal tip growth of Arabidopsis pollen tubes. '

  text: 'Cytokinin is a phytohormone that is well known for its roles in numerous
    plant growth and developmental processes, yet it has also been linked to abiotic
    stress response in a less defined manner. Arabidopsis (Arabidopsis thaliana) Cytokinin
    Response Factor 6 (CRF6) is a cytokinin-responsive AP2/ERF-family transcription
    factor that, through the cytokinin signaling pathway, plays a key role in the
    inhibition of dark-induced senescence. CRF6 expression is also induced by oxidative
    stress, and here we show a novel function for CRF6 in relation to oxidative stress
    and identify downstream transcriptional targets of CRF6 that are repressed in
    response to oxidative stress. Analysis of transcriptomic changes in wild-type
    and crf6 mutant plants treated with H2O2 identified CRF6-dependent differentially
    expressed transcripts, many of which were repressed rather than induced. Moreover,
    many repressed genes also show decreased expression in 35S:CRF6 overexpressing
    plants. Together, these findings suggest that CRF6 functions largely as a transcriptional
    repressor. Interestingly, among the H2O2 repressed CRF6-dependent transcripts
    was a set of five genes associated with cytokinin processes: (signaling) ARR6,
    ARR9, ARR11, (biosynthesis) LOG7, and (transport) ABCG14. We have examined mutants
    of these cytokinin-associated target genes to reveal novel connections to oxidative
    stress. Further examination of CRF6-DNA interactions indicated that CRF6 may regulate
    its targets both directly and indirectly. Together, this shows that CRF6 functions
    during oxidative stress as a negative regulator to control this cytokinin-associated
    module of CRF6- dependent genes and establishes a novel connection between cytokinin
    and oxidative stress response.'

  text: 'Although cytokinins (CKs) affect a number of processes connected with chloroplasts,
    it has never been rigorously proven that chloroplasts contain CKs. We isolated
    intact chloroplasts from tobacco (Nicotiana tabacum L. cv SR1) and wheat (Triticum
    aestivum L. cv Ritmo) leaves and determined their CKs by liquid chromatography/tandem
    mass spectroscopy. Chloroplasts from both species contained a whole spectrum of
    CKs, including free bases (zeatin and isopentenyladenine), ribosides (zeatin riboside,
    and isopentenyladenosine), ribotides (isopentenyladenosine-5′-monophosphate, zeatin
    riboside-5′-monophosphate, and dihydrozeatin riboside-5′-monophosphate), and N-glucosides
    (zeatin-N 9-glucoside, dihydrozeatin-N 9-glucoside, zeatin-N 7-glucoside, and
    isopentenyladenine-N-glucosides). In chloroplasts there was a moderately higher
    relative amount of bases, ribosides, and ribotides than in leaves, and a significantly
    increased level ofN 9-glucosides of zeatin and dihydrozeatin. Tobacco and wheat
    chloroplasts were prepared from leaves at the end of either a dark or light period.
    After a dark period, chloroplasts accumulated more CKs than after a light period.
    The differences were moderate for free bases and ribosides, but highly significant
    for glucosides. Tobacco chloroplasts from dark-treated leaves contained zeatin
    riboside-O-glucoside and dihydrozeatin riboside-O-glucoside, as well as a relatively
    high CK oxidase activity. These data show that chloroplasts contain a whole spectrum
    of CKs and the enzymatic activity necessary for their metabolism. '
