  text: Treating sick group members is a hallmark of collective disease defence in
    vertebrates and invertebrates alike. Despite substantial effects on pathogen fitness
    and epidemiology, it is still largely unknown how pathogens react to the selection
    pressure imposed by care intervention. Using social insects and pathogenic fungi,
    we here performed a serial passage experiment in the presence or absence of colony
    members, which provide social immunity by grooming off infectious spores from
    exposed individuals. We found specific effects on pathogen diversity, virulence
    and transmission. Under selection of social immunity, pathogens invested into
    higher spore production, but spores were less virulent. Notably, they also elicited
    a lower grooming response in colony members, compared with spores from the individual
    host selection lines. Chemical spore analysis suggested that the spores from social
    selection lines escaped the caregivers’ detection by containing lower levels of
    ergosterol, a key fungal membrane component. Experimental application of chemically
    pure ergosterol indeed induced sanitary grooming, supporting its role as a microbe-associated
    cue triggering host social immunity against fungal pathogens. By reducing this
    detection cue, pathogens were able to evade the otherwise very effective collective
    disease defences of their social hosts.

  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: "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: 'Clathrin-mediated endocytosis (CME) is a crucial cellular process implicated
    in many aspects of plant growth, development, intra- and inter-cellular signaling,
    nutrient uptake and pathogen defense. Despite these significant roles, little
    is known about the precise molecular details of how it functions in planta. In
    order to facilitate the direct quantitative study of plant CME, here we review
    current routinely used methods and present refined, standardized quantitative
    imaging protocols which allow the detailed characterization of CME at multiple
    scales in plant tissues. These include: (i) an efficient electron microscopy protocol
    for the imaging of Arabidopsis CME vesicles in situ, thus providing a method for
    the detailed characterization of the ultra-structure of clathrin-coated vesicles;
    (ii) a detailed protocol and analysis for quantitative live-cell fluorescence
    microscopy to precisely examine the temporal interplay of endocytosis components
    during single CME events; (iii) a semi-automated analysis to allow the quantitative
    characterization of global internalization of cargos in whole plant tissues; and
    (iv) an overview and validation of useful genetic and pharmacological tools to
    interrogate the molecular mechanisms and function of CME in intact plant samples.'

  text: In plants, clathrin mediated endocytosis (CME) represents the major route
    for cargo internalisation from the cell surface. It has been assumed to operate
    in an evolutionary conserved manner as in yeast and animals. Here we report characterisation
    of ultrastructure, dynamics and mechanisms of plant CME as allowed by our advancement
    in electron microscopy and quantitative live imaging techniques. Arabidopsis CME
    appears to follow the constant curvature model and the bona fide CME population
    generates vesicles of a predominantly hexagonal-basket type; larger and with faster
    kinetics than in other models. Contrary to the existing paradigm, actin is dispensable
    for CME events at the plasma membrane but plays a unique role in collecting endocytic
    vesicles, sorting of internalised cargos and directional endosome movement that
    itself actively promote CME events. Internalized vesicles display a strongly delayed
    and sequential uncoating. These unique features highlight the independent evolution
    of the plant CME mechanism during the autonomous rise of multicellularity in eukaryotes.

  text: 'Clathrin-Mediated Endocytosis (CME) is an aspect of cellular trafficking
    that is constantly regulated for mediating developmental and physiological responses.
    The main aim of my thesis is to decipher the basic mechanisms of CME and post-endocytic
    trafficking in the whole multicellular organ systems of Arabidopsis. The first
    chapter of my thesis describes the search for new components involved in CME.
    Tandem affinity purification was conducted using CLC and its interacting partners
    were identified. Amongst the identified proteins were the Auxilin-likes1 and 2
    (Axl1/2), putative uncoating factors, for which we made a full functional analysis.
    Over-expression of Axl1/2 causes extreme modifications in the dynamics of the
    machinery proteins and inhibition of endocytosis altogether. However the loss
    of function of the axl1/2 did not present any cellular or physiological phenotype,
    meaning Auxilin-likes do not form the major uncoating machinery. The second chapter
    of my thesis describes the establishment/utilisation of techniques to capture
    the dynamicity and the complexity of CME and post-endocytic trafficking. We have
    studied the development of endocytic pits at the PM – specifically, the mode of
    membrane remodeling during pit development and the role of actin in it, given
    plant cells possess high turgor pressure. Utilizing the improved z-resolution
    of TIRF and VAEM techniques, we captured the time-lapse of the endocytic events
    at the plasma membrane; and using particle detection software, we quantitatively
    analysed all the endocytic trajectories in an unbiased way to obtain the endocytic
    rate of the system. This together with the direct analysis of cargo internalisation
    from the PM provided an estimate on the endocytic potential of the cell. We also
    developed a methodology for ultrastructural analysis of different populations
    of Clathrin-Coated Structures (CCSs) in both PM and endomembranes in unroofed
    protoplasts. Structural analysis, together with the intensity profile of CCSs
    at the PM show that the mode of CCP development at the PM follows ‘Constant curvature
    model’; meaning that clathrin polymerisation energy is a major contributing factor
    of membrane remodeling. In addition, other analyses clearly show that actin is
    not required for membrane remodeling during invagination or any other step of
    CCP development, despite the prevalent high turgor pressure. However, actin is
    essential in orchestrating the post-endocytic trafficking of CCVs facilitating
    the EE formation. We also observed that the uncoating process post-endocytosis
    is not immediate; an alternative mechanism of uncoating – Sequential multi-step
    process – functions in the cell. Finally we also looked at one of the important
    physiological stimuli modulating the process – hormone, auxin. auxin has been
    known to influence CME before. We have made a detailed study on the concentration-time
    based effect of auxin on the machinery proteins, CCP development, and the specificity
    of cargoes endocytosed. To this end, we saw no general effect of auxin on CME
    at earlier time points. However, very low concentration of IAA, such as 50nM,
    accelerates endocytosis of specifically PIN2 through CME. Such a tight regulatory
    control with high specificity to PIN2 could be essential in modulating its polarity. '

  text: Clathrin-mediated endocytosis (CME) is a cellular trafficking process in which
    cargoes and lipids are internalized from the plasma membrane into vesicles coated
    with clathrin and adaptor proteins. CME is essential for many developmental and
    physiological processes in plants, but its underlying mechanism is not well characterised
    compared to that in yeast and animal systems. Here, we searched for new factors
    involved in CME in Arabidopsis thaliana by performing Tandem Affinity Purification
    of proteins that interact with clathrin light chain, a principal component of
    the clathrin coat. Among the confirmed interactors, we found two putative homologues
    of the clathrin-coat uncoating factor auxilin previously described in non-plant
    systems. Overexpression of AUXILIN-LIKE1 and AUXILIN-LIKE2 in A. thaliana caused
    an arrest of seedling growth and development. This was concomitant with inhibited
    endocytosis due to blocking of clathrin recruitment after the initial step of
    adaptor protein binding to the plasma membrane. By contrast, auxilin-like(1/2)
    loss-of-function lines did not present endocytosis-related developmental or cellular
    phenotypes under normal growth conditions. This work contributes to the on-going
    characterization of the endocytotic machinery in plants and provides a robust
    tool for conditionally and specifically interfering with CME in A. thaliana.

  text: n contrast with the wealth of recent reports about the function of μ-adaptins
    and clathrin adaptor protein (AP) complexes, there is very little information
    about the motifs that determine the sorting of membrane proteins within clathrin-coated
    vesicles in plants. Here, we investigated putative sorting signals in the large
    cytosolic loop of the Arabidopsis (Arabidopsis thaliana) PIN-FORMED1 (PIN1) auxin
    transporter, which are involved in binding μ-adaptins and thus in PIN1 trafficking
    and localization. We found that Phe-165 and Tyr-280, Tyr-328, and Tyr-394 are
    involved in the binding of different μ-adaptins in vitro. However, only Phe-165,
    which binds μA(μ2)- and μD(μ3)-adaptin, was found to be essential for PIN1 trafficking
    and localization in vivo. The PIN1:GFP-F165A mutant showed reduced endocytosis
    but also localized to intracellular structures containing several layers of membranes
    and endoplasmic reticulum (ER) markers, suggesting that they correspond to ER
    or ER-derived membranes. While PIN1:GFP localized normally in a μA (μ2)-adaptin
    mutant, it accumulated in big intracellular structures containing LysoTracker
    in a μD (μ3)-adaptin mutant, consistent with previous results obtained with mutants
    of other subunits of the AP-3 complex. Our data suggest that Phe-165, through
    the binding of μA (μ2)- and μD (μ3)-adaptin, is important for PIN1 endocytosis
    and for PIN1 trafficking along the secretory pathway, respectively.
