A central question in developmental biology concerns the mechanism of generation and maintenance of cell polarity, because these processes are essential for many cellular functions and multicellular development [1]. In plants, cell polarity has an additional role in mediating directional transport of the plant hormone auxin that is crucial for multiple developmental processes [2-4]. In addition, plant cells have a complex extracellular matrix, the cell wall [5, 6], whose role in regulating cellular processes, including cell polarity, is unexplored. We have found that polar distribution of PIN auxin transporters [7] in plant cells is maintained by connections between polar domains at the plasma membrane and the cell wall. Genetic and pharmacological interference with cellulose, the major component of the cell wall, or mechanical interference with the cell wall disrupts these connections and leads to increased lateral diffusion and loss of polar distribution of PIN transporters for the phytohormone auxin. Our results reveal a plant-specific mechanism for cell polarity maintenance and provide a conceptual framework for modulating cell polarity and plant development via endogenous and environmental manipulations of the cellulose-based extracellular matrix.

text: Phototropism is an adaptation response, through which plants grow towards
the light. It involves light perception and asymmetric distribution of the plant
hormone auxin. Here we identify a crucial part of the mechanism for phototropism,
revealing how light perception initiates auxin redistribution that leads to directional
growth. We show that light polarizes the cellular localization of the auxin efflux
carrier PIN3 in hypocotyl endodermis cells, resulting in changes in auxin distribution
and differential growth. In the dark, high expression and activity of the PINOID
(PID) kinase correlates with apolar targeting of PIN3 to all cell sides. Following
illumination, light represses PINOID transcription and PIN3 is polarized specifically
to the inner cell sides by GNOM ARF GTPase GEF (guanine nucleotide exchange factor)-dependent
trafficking. Thus, differential trafficking at the shaded and illuminated hypocotyl
side aligns PIN3 polarity with the light direction, and presumably redirects auxin
flow towards the shaded side, where auxin promotes growth, causing hypocotyls
to bend towards the light. Our results imply that PID phosphorylation-dependent
recruitment of PIN proteins into distinct trafficking pathways is a mechanism
to polarize auxin fluxes in response to different environmental and endogenous
cues.

text: PIN-FORMED (PIN)-dependent auxin transport is essential for plant development
and its modulation in response to the environment or endogenous signals. A NON-PHOTOTROPIC
HYPOCOTYL 3 (NPH3)-like protein, MACCHI-BOU 4 (MAB4), has been shown to control
PIN1 localization during organ formation, but its contribution is limited. The
Arabidopsis genome contains four genes, MAB4/ENP/NPY1-LIKE1 (MEL1), MEL2, MEL3
and MEL4, highly homologous to MAB4. Genetic analysis disclosed functional redundancy
between MAB4 and MEL genes in regulation of not only organ formation but also
of root gravitropism, revealing that NPH3 family proteins have a wider range of
functions than previously suspected. Multiple mutants showed severe reduction
in PIN abundance and PIN polar localization, leading to defective expression of
an auxin responsive marker DR5rev::GFP. Pharmacological analyses and fluorescence
recovery after photo-bleaching experiments showed that mel mutations increase
PIN2 internalization from the plasma membrane, but affect neither intracellular
PIN2 trafficking nor PIN2 lateral diffusion at the plasma membrane. Notably, all
MAB4 subfamily proteins show polar localization at the cell periphery in plants.
The MAB4 polarity was almost identical to PIN polarity. Our results suggest that
the MAB4 subfamily proteins specifically retain PIN proteins in a polarized manner
at the plasma membrane, thus controlling directional auxin transport and plant
development.

text: Endocytosis is a crucial mechanism by which eukaryotic cells internalize extracellular
and plasma membrane material, and it is required for a multitude of cellular and
developmental processes in unicellular and multicellular organisms. In animals
and yeast, the best characterized pathway for endocytosis depends on the function
of the vesicle coat protein clathrin. Clathrinmediated endocytosis has recently
been demonstrated also in plant cells, but its physiological and developmental
roles remain unclear. Here, we assessed the roles of the clathrin-mediated mechanism
of endocytosis in plants by genetic means. We interfered with clathrin heavy chain
(CHC) function through mutants and dominant-negative approaches in Arabidopsis
thaliana and established tools to manipulate clathrin function in a cell type-specific
manner. The chc2 single mutants and dominant-negative CHC1 (HUB) transgenic lines
were defective in bulk endocytosis as well as in internalization of prominent
plasma membrane proteins. Interference with clathrin-mediated endocytosis led
to defects in constitutive endocytic recycling of PIN auxin transporters and their
polar distribution in embryos and roots. Consistent with this, these lines had
altered auxin distribution patterns and associated auxin transport-related phenotypes,
such as aberrant embryo patterning, imperfect cotyledon specification, agravitropic
growth, and impaired lateral root organogenesis. Together, these data demonstrate
a fundamental role for clathrin function in cell polarity, growth, patterning,
and organogenesis in plants.

text: 'Background: Whereas the majority of animals develop toward a predetermined
body plan, plants show iterative growth and continually produce new organs and
structures from actively dividing meristems. This raises an intriguing question:
How are these newly developed organs patterned? In Arabidopsis embryos, radial
symmetry is broken by the bisymmetric specification of the cotyledons in the apical
domain. Subsequently, this bisymmetry is propagated to the root promeristem. Results:
Here we present a mutually inhibitory feedback loop between auxin and cytokinin
that sets distinct boundaries of hormonal output. Cytokinins promote the bisymmetric
distribution of the PIN-FORMED (PIN) auxin efflux proteins, which channel auxin
toward a central domain. High auxin promotes transcription of the cytokinin signaling
inhibitor AHP6, which closes the interaction loop. This bisymmetric auxin response
domain specifies the differentiation of protoxylem in a bisymmetric pattern. In
embryonic roots, cytokinin is required to translate a bisymmetric auxin response
in the cotyledons to a bisymmetric vascular pattern in the root promeristem. Conclusions:
Our results present an interactive feedback loop between hormonal signaling and
transport by which small biases in hormonal input are propagated into distinct
signaling domains to specify the vascular pattern in the root meristem. It is
an intriguing possibility that such a mechanism could transform radial patterns
and allow continuous vascular connections between other newly emerging organs.'

text: The phytohormone auxin is an important determinant of plant development. Directional
auxin flow within tissues depends on polar localization of PIN auxin transporters.
To explore regulation of PIN-mediated auxin transport, we screened for suppressors
of PIN1 overexpression (supo) and identified an inositol polyphosphate 1-phosphatase
mutant (supo1), with elevated inositol trisphosphate (InsP 3) and cytosolic Ca
2+ levels. Pharmacological and genetic increases in InsP 3 or Ca 2+ levels also
suppressed the PIN1 gain-of-function phenotypes and caused defects in basal PIN
localization, auxin transport and auxin-mediated development. In contrast, the
reductions in InsP 3 levels and Ca 2+ signaling antagonized the effects of the
supo1 mutation and disrupted preferentially apical PIN localization. InsP 3 and
Ca 2+ are evolutionarily conserved second messengers involved in various cellular
functions, particularly stress responses. Our findings implicate them as modifiers
of cell polarity and polar auxin transport, and highlight a potential integration
point through which Ca 2+ signaling-related stimuli could influence auxin-mediated
development.

text: The polarized transport of the phytohormone auxin [1], which is crucial for
the regulation of different stages of plant development [2, 3], depends on the
asymmetric plasma membrane distribution of the PIN-FORMED (PIN) auxin efflux carriers
[4, 5]. The PIN polar localization results from clathrin-mediated endocytosis
(CME) from the plasma membrane and subsequent polar recycling [6]. The Arabidopsis
genome encodes two groups of dynamin-related proteins (DRPs) that show homology
to mammalian dynamin - a protein required for fission of endocytic vesicles during
CME [7, 8]. Here we show by coimmunoprecipitation (coIP), bimolecular fluorescence
complementation (BiFC), and Förster resonance energy transfer (FRET) that members
of the DRP1 group closely associate with PIN proteins at the cell plate. Localization
and phenotypic analysis of novel drp1 mutants revealed a requirement for DRP1
function in correct PIN distribution and in auxin-mediated development. We propose
that rapid and specific internalization of PIN proteins mediated by the DRP1 proteins
and the associated CME machinery from the cell plate membranes during cytokinesis
is an important mechanism for proper polar PIN positioning in interphase cells.

text: The phytohormone auxin is vital to plant growth and development. A unique
property of auxin among all other plant hormones is its cell-to-cell polar transport
that requires activity of polarly localized PIN-FORMED (PIN) auxin efflux transporters.
Despite the substantial molecular insight into the cellular PIN polarization,
the mechanistic understanding for developmentally and environmentally regulated
PIN polarization is scarce. The long-standing belief that auxin modulates its
own transport by means of a positive feedback mechanism has inspired both experimentalists
and theoreticians for more than two decades. Recently, theoretical models for
auxin-dependent patterning in plants include the feedback between auxin transport
and the PIN protein localization. These computer models aid to assess the complexity
of plant development by testing and predicting plausible scenarios for various
developmental processes that occur in planta. Although the majority of these models
rely on purely heuristic principles, the most recent mechanistic models tentatively
integrate biologically testable components into known cellular processes that
underlie the PIN polarity regulation. The existing and emerging computational
approaches to describe PIN polarization are presented and discussed in the light
of recent experimental data on the PIN polar targeting.

Plants take up iron from the soil using the IRON-REGULATED TRANSPORTER 1 (IRT1) high-affinity iron transporter at the root surface. Sophisticated regulatory mechanisms allow plants to tightly control the levels of IRT1, ensuring optimal absorption of essential but toxic iron. Here, we demonstrate that overexpression of Arabidopsis thaliana IRT1 leads to constitutive IRT1 protein accumulation, metal overload, and oxidative stress. IRT1 is unexpectedly found in trans-Golgi network/early endosomes of root hair cells, and its levels and localization are unaffected by iron nutrition. Using pharmacological approaches, we show that IRT1 cycles to the plasma membrane to perform iron and metal uptake at the cell surface and is sent to the vacuole for proper turnover. We also prove that IRT1 is monoubiquitinated on several cytosol-exposed residues in vivo and that mutation of two putative monoubiquitination target residues in IRT1 triggers stabilization at the plasma membrane and leads to extreme lethality. Together, these data suggest a model in which monoubiquitin-dependent internalization/sorting and turnover keep the plasma membrane pool of IRT1 low to ensure proper iron uptake and to prevent metal toxicity. More generally, our work demonstrates the existence of monoubiquitin-dependent trafficking to lytic vacuoles in plants and points to proteasome-independent turnover of plasma membrane proteins.

text: Summary Gravitropism aligns plant growth with gravity. It involves gravity
perception and the asymmetric distribution of the phytohormone auxin. Here we
provide insights into the mechanism for hypocotyl gravitropic growth. We show
that the Arabidopsis thaliana PIN3 auxin transporter is required for the asymmetric
auxin distribution for the gravitropic response. Gravistimulation polarizes PIN3
to the bottom side of hypocotyl endodermal cells, which correlates with an increased
auxin response at the lower hypocotyl side. Both PIN3 polarization and hypocotyl
bending require the activity of the trafficking regulator GNOM and the protein
kinase PINOID. Our data suggest that gravity-induced PIN3 polarization diverts
the auxin flow to mediate the asymmetric distribution of auxin for gravitropic
shoot bending.

text: Root system architecture depends on lateral root (LR) initiation that takes
place in a relatively narrow developmental window (DW). Here, we analyzed the
role of auxin gradients established along the parent root in defining this DW
for LR initiation. Correlations between auxin distribution and response, and spatiotemporal
control of LR initiation were analyzed in Arabidopsis thaliana and tomato (Solanum
lycopersicum). In both Arabidopsis and tomato roots, a well defined zone, where
auxin content and response are minimal, demarcates the position of a DW for founder
cell specification and LR initiation. We show that in the zone of auxin minimum
pericycle cells have highest probability to become founder cells and that auxin
perception via the TIR1/AFB pathway, and polar auxin transport, are essential
for the establishment of this zone. Altogether, this study reveals that the same
morphogen-like molecule, auxin, can act simultaneously as a morphogenetic trigger
of LR founder cell identity and as a gradient-dependent signal defining positioning
of the founder cell specification. This auxin minimum zone might represent an
important control mechanism ensuring the LR initiation steadiness and the acropetal
LR initiation pattern. © 2011 The Authors. New Phytologist © 2011 New Phytologist

text: Carrier-dependent, intercellular auxin transport is central to the developmental
patterning of higher plants (tracheophytes). The evolution of this polar auxin
transport might be linked to the translocation of some PIN auxin efflux carriers
from their presumably ancestral localization at the endoplasmic reticulum (ER)
to the polar domains at the plasma membrane. Here we propose an eventually ancient
mechanism of intercellular auxin distribution by ER-localized auxin transporters
involving intracellular auxin retention and switch-like release from the ER. The
proposed model integrates feedback circuits utilizing the conserved nuclear auxin
signaling for the regulation of PIN transcription and a hypothetical ER-based
signaling for the regulation of PIN-dependent transport activity at the ER. Computer
simulations of the model revealed its plausibility for generating auxin channels
and localized auxin maxima highlighting the possibility of this alternative mechanism
for polar auxin transport.

text: Cytokinin is an important regulator of plant growth and development. In Arabidopsis
thaliana, the two-component phosphorelay mediated through a family of histidine
kinases and response regulators is recognized as the principal cytokinin signal
transduction mechanism activating the complex transcriptional response to control
various developmental processes. Here, we identified an alternative mode of cytokinin
action that uses endocytic trafficking as a means to direct plant organogenesis.
This activity occurs downstream of known cytokinin receptors but through a branch
of the cytokinin signaling pathway that does not involve transcriptional regulation.
We show that cytokinin regulates endocytic recycling of the auxin efflux carrier
PINFORMED1 (PIN1) by redirecting it for lytic degradation in vacuoles. Stimulation
of the lytic PIN1 degradation is not a default effect for general downregulation
of proteins from plasma membranes, but a specific mechanism to rapidly modulate
the auxin distribution in cytokinin-mediated developmental processes.

text: Cell polarity reflected by asymmetric distribution of proteins at the plasma
membrane is a fundamental feature of unicellular and multicellular organisms.
It remains conceptually unclear how cell polarity is kept in cell wall-encapsulated
plant cells. We have used super-resolution and semi-quantitative live-cell imaging
in combination with pharmacological, genetic, and computational approaches to
reveal insights into the mechanism of cell polarity maintenance in Arabidopsis
thaliana. We show that polar-competent PIN transporters for the phytohormone auxin
are delivered to the center of polar domains by super-polar recycling. Within
the plasma membrane, PINs are recruited into non-mobile membrane clusters and
their lateral diffusion is dramatically reduced, which ensures longer polar retention.
At the circumventing edges of the polar domain, spatially defined internalization
of escaped cargos occurs by clathrin-dependent endocytosis. Computer simulations
confirm that the combination of these processes provides a robust mechanism for
polarity maintenance in plant cells. Moreover, our study suggests that the regulation
of lateral diffusion and spatially defined endocytosis, but not super-polar exocytosis
have primary importance for PIN polarity maintenance.

text: Endomembrane trafficking relies on the coordination of a highly complex, dynamic
network of intracellular vesicles. Understanding the network will require a dissection
of cargo and vesicle dynamics at the cellular level in vivo. This is also a key
to establishing a link between vesicular networks and their functional roles in
development. We used a high-content intracellular screen to discover small molecules
targeting endomembrane trafficking in vivo in a complex eukaryote, Arabidopsis
thaliana. Tens of thousands of molecules were prescreened and a selected subset
was interrogated against a panel of plasma membrane (PM) and other endomembrane
compartment markers to identify molecules that altered vesicle trafficking. The
extensive image dataset was transformed by a flexible algorithm into a marker-by-phenotype-by-treatment
time matrix and revealed groups of molecules that induced similar subcellular
fingerprints (clusters). This matrix provides a platform for a systems view of
trafficking. Molecules from distinct clusters presented avenues and enabled an
entry point to dissect recycling at the PM, vacuolar sorting, and cell-plate maturation.
Bioactivity in human cells indicated the value of the approach to identifying
small molecules that are active in diverse organisms for biology and drug discovery.

text: In multicellular organisms, morphogenesis relies on a strict coordination
in time and space of cell proliferation and differentiation. In contrast to animals,
plant development displays continuous organ formation and adaptive growth responses
during their lifespan relying on a tight coordination of cell proliferation. How
developmental signals interact with the plant cell-cycle machinery is largely
unknown. Here, we characterize plant A2-type cyclins, a small gene family of mitotic
cyclins, and show how they contribute to the fine-tuning of local proliferation
during plant development. Moreover, the timely repression of CYCA2;3 expression
in newly formed guard cells is shown to require the stomatal transcription factors
FOUR LIPS/MYB124 and MYB88, providing a direct link between developmental programming
and cell-cycle exit in plants. Thus, transcriptional downregulation of CYCA2s
represents a critical mechanism to coordinate proliferation during plant development.

text: Subcellular trafficking is required for a multitude of functions in eukaryotic
cells. It involves regulation of cargo sorting, vesicle formation, trafficking
and fusion processes at multiple levels. Adaptor protein (AP) complexes are key
regulators of cargo sorting into vesicles in yeast and mammals but their existence
and function in plants have not been demonstrated. Here we report the identification
of the protein-affected trafficking 4 (pat4) mutant defective in the putative
δ subunit of the AP-3 complex. pat4 and pat2, a mutant isolated from the same
GFP imaging-based forward genetic screen that lacks a functional putative AP-3
β, as well as dominant negative AP-3 μ transgenic lines display undistinguishable
phenotypes characterized by largely normal morphology and development, but strong
intracellular accumulation of membrane proteins in aberrant vacuolar structures.
All mutants are defective in morphology and function of lytic and protein storage
vacuoles (PSVs) but show normal sorting of reserve proteins to PSVs. Immunoprecipitation
experiments and genetic studies revealed tight functional and physical associations
of putative AP-3 β and AP-3 δ subunits. Furthermore, both proteins are closely
linked with putative AP-3 μ and σ subunits and several components of the clathrin
and dynamin machineries. Taken together, these results demonstrate that AP complexes,
similar to those in other eukaryotes, exist in plants, and that AP-3 plays a specific
role in the regulation of biogenesis and function of vacuoles in plant cells.

text: 'Multicellular organisms depend on cell production, cell fate specification,
and correct patterning to shape their adult body. In plants, auxin plays a prominent
role in the timely coordination of these different cellular processes. A well-studied
example is lateral root initiation, in which auxin triggers founder cell specification
and cell cycle activation of xylem pole–positioned pericycle cells. Here, we report
that the E2Fa transcription factor of Arabidopsis thaliana is an essential component
that regulates the asymmetric cell division marking lateral root initiation. Moreover,
we demonstrate that E2Fa expression is regulated by the LATERAL ORGAN BOUNDARY
DOMAIN18/LATERAL ORGAN BOUNDARY DOMAIN33 (LBD18/LBD33) dimer that is, in turn,
regulated by the auxin signaling pathway. LBD18/LBD33 mediates lateral root organogenesis
through E2Fa transcriptional activation, whereas E2Fa expression under control
of the LBD18 promoter eliminates the need for LBD18. Besides lateral root initiation,
vascular patterning is disrupted in E2Fa knockout plants, similarly as it is affected
in auxin signaling and lbd mutants, indicating that the transcriptional induction
of E2Fa through LBDs represents a general mechanism for auxin-dependent cell cycle
activation. Our data illustrate how a conserved mechanism driving cell cycle entry
has been adapted evolutionarily to connect auxin signaling with control of processes
determining plant architecture. '

text: Endocytosis in plants has an essential role not only for basic cellular functions
but also for growth and development, hormonal signaling and communication with
the environment including nutrient delivery, toxin avoidance, and pathogen defense.
The major endocytic mechanism in plants depends on the coat protein clathrin.
It starts by clathrin-coated vesicle formation at the plasma membrane, where specific
cargoes are recognized and packaged for internalization. Recently, genetic, biochemical
and advanced microscopy studies provided initial insights into mechanisms and
roles of clathrin-mediated endocytosis in plants. Here we summarize the present
state of knowledge and compare mechanisms of clathrin-mediated endocytosis in
plants with animal and yeast paradigms as well as review plant-specific regulations
and roles of this process.
