  text: Phytohormone auxin and its directional transport mediate much of the remarkably
    plastic development of higher plants. Positive feedback between auxin signaling
    and transport is a prerequisite for (1) self-organizing processes, including vascular
    tissue formation, and (2) directional growth responses such as gravitropism. Here,
    we identify a mechanism by which auxin signaling directly targets PIN auxin transporters.
    Via the cell-surface AUXIN-BINDING PROTEIN1 (ABP1)-TRANSMEMBRANE KINASE 1 (TMK1)
    receptor module, auxin rapidly induces phosphorylation and thus stabilization
    of PIN2. Following gravistimulation, initial auxin asymmetry activates autophosphorylation
    of the TMK1 kinase. This induces TMK1 interaction with and phosphorylation of
    PIN2, stabilizing PIN2 at the lower root side, thus reinforcing asymmetric auxin
    flow for root bending. Upstream of TMK1 in this regulation, ABP1 acts redundantly
    with the root-expressed ABP1-LIKE 3 (ABL3) auxin receptor. Such positive feedback
    between cell-surface auxin signaling and PIN-mediated polar auxin transport is
    fundamental for robust root gravitropism and presumably for other self-organizing
    developmental phenomena.

  text: Conserved signaling cascades monitor protein-folding homeostasis to ensure
    proper cellular function. One of the evolutionary conserved key players is IRE1,
    which maintains endoplasmic reticulum (ER) homeostasis through the unfolded protein
    response (UPR). Upon accumulation of misfolded proteins in the ER, IRE1 forms
    clusters on the ER membrane to initiate UPR signaling. What regulates IRE1 cluster
    formation is not fully understood. Here, we show that the ER lumenal domain (LD)
    of human IRE1α forms biomolecular condensates in vitro. IRE1α LD condensates were
    stabilized both by binding to unfolded polypeptides as well as by tethering to
    model membranes, suggesting their role in assembling IRE1α into signaling-competent
    stable clusters. Molecular dynamics simulations indicated that weak multivalent
    interactions drive IRE1α LD clustering. Mutagenesis experiments identified disordered
    regions in IRE1α LD to control its clustering in vitro and in cells. Importantly,
    dysregulated clustering of IRE1α mutants led to defects in IRE1α signaling. Our
    results revealed that disordered regions in IRE1α LD control its clustering and
    suggest their role as a common strategy in regulating protein assembly on membranes.

  text: Autophagosomes are double-membraned vesicles that traffic harmful or unwanted
    cellular macromolecules to the vacuole for recycling. Although autophagosome biogenesis
    has been extensively studied, autophagosome maturation, i.e., delivery and fusion
    with the vacuole, remains largely unknown in plants. Here, we have identified
    an autophagy adaptor, CFS1, that directly interacts with the autophagosome marker
    ATG8 and localizes on both membranes of the autophagosome. Autophagosomes form
    normally in Arabidopsis thaliana cfs1 mutants, but their delivery to the vacuole
    is disrupted. CFS1’s function is evolutionarily conserved in plants, as it also
    localizes to the autophagosomes and plays a role in autophagic flux in the liverwort
    Marchantia polymorpha. CFS1 regulates autophagic flux by bridging autophagosomes
    with the multivesicular body-localized ESCRT-I component VPS23A, leading to the
    formation of amphisomes. Similar to CFS1-ATG8 interaction, disrupting the CFS1-VPS23A
    interaction blocks autophagic flux and renders plants sensitive to nitrogen starvation.
    Altogether, our results reveal a conserved vacuolar sorting hub that regulates
    autophagic flux in plants.

  text: The phytohormone auxin triggers transcriptional reprogramming through a well-characterized
    perception machinery in the nucleus. By contrast, mechanisms that underlie fast
    effects of auxin, such as the regulation of ion fluxes, rapid phosphorylation
    of proteins or auxin feedback on its transport, remain unclear1,2,3. Whether auxin-binding
    protein 1 (ABP1) is an auxin receptor has been a source of debate for decades1,4.
    Here we show that a fraction of Arabidopsis thaliana ABP1 is secreted and binds
    auxin specifically at an acidic pH that is typical of the apoplast. ABP1 and its
    plasma-membrane-localized partner, transmembrane kinase 1 (TMK1), are required
    for the auxin-induced ultrafast global phospho-response and for downstream processes
    that include the activation of H+-ATPase and accelerated cytoplasmic streaming.
    abp1 and tmk mutants cannot establish auxin-transporting channels and show defective
    auxin-induced vasculature formation and regeneration. An ABP1(M2X) variant that
    lacks the capacity to bind auxin is unable to complement these defects in abp1
    mutants. These data indicate that ABP1 is the auxin receptor for TMK1-based cell-surface
    signalling, which mediates the global phospho-response and auxin canalization.

  text: Ustilago maydis is a biotrophic phytopathogenic fungus that causes corn smut
    disease. As a well-established model system, U. maydis is genetically fully accessible
    with large omics datasets available and subject to various biological questions
    ranging from DNA-repair, RNA-transport, and protein secretion to disease biology.
    For many genetic approaches, tight control of transgene regulation is important.
    Here we established an optimised version of the Tetracycline-ON (TetON) system
    for U. maydis. We demonstrate the Tetracycline concentration-dependent expression
    of fluorescent protein transgenes and the system’s suitability for the induced
    expression of the toxic protein BCL2 Associated X-1 (Bax1). The Golden Gate compatible
    vector system contains a native minimal promoter from the mating factor a-1 encoding
    gene, mfa with ten copies of the tet-regulated operator (tetO) and a codon optimised
    Tet-repressor (tetR*) which is translationally fused to the native transcriptional
    corepressor Mql1 (UMAG_05501). The metabolism-independent transcriptional regulator
    system is functional both, in liquid culture as well as on solid media in the
    presence of the inducer and can become a useful tool for toxin-antitoxin studies,
    identification of antifungal proteins, and to study functions of toxic gene products
    in Ustilago maydis.

  text: Despite the growing interest in using chemical genetics in plant research,
    small molecule target identification remains a major challenge. The cellular thermal
    shift assay coupled with high-resolution mass spectrometry (CETSA MS) that monitors
    changes in the thermal stability of proteins caused by their interactions with
    small molecules, other proteins, or posttranslational modifications, allows the
    discovery of drug targets or the study of protein–metabolite and protein–protein
    interactions mainly in mammalian cells. To showcase the applicability of this
    method in plants, we applied CETSA MS to intact Arabidopsis thaliana cells and
    identified the thermal proteome of the plant-specific glycogen synthase kinase
    3 (GSK3) inhibitor, bikinin. A comparison between the thermal and the phosphoproteomes
    of bikinin revealed the auxin efflux carrier PIN-FORMED1 (PIN1) as a substrate
    of the Arabidopsis GSK3s that negatively regulate the brassinosteroid signaling.
    We established that PIN1 phosphorylation by the GSK3s is essential for maintaining
    its intracellular polarity that is required for auxin-mediated regulation of vascular
    patterning in the leaf, thus revealing cross-talk between brassinosteroid and
    auxin signaling.
