text: The plant hormone indole-acetic acid (auxin) is essential for many aspects
of plant development. Auxin-mediated growth regulation typically involves the
establishment of an auxin concentration gradient mediated by polarly localized
auxin transporters. The localization of auxin carriers and their amount at the
plasma membrane are controlled by membrane trafficking processes such as secretion,
endocytosis, and recycling. In contrast to endocytosis or recycling, how the secretory
pathway mediates the localization of auxin carriers is not well understood. In
this study we have used the differential cell elongation process during apical
hook development to elucidate the mechanisms underlying the post-Golgi trafficking
of auxin carriers in Arabidopsis. We show that differential cell elongation during
apical hook development is defective in Arabidopsis mutant echidna (ech). ECH
protein is required for the trans-Golgi network (TGN)-mediated trafficking of
the auxin influx carrier AUX1 to the plasma membrane. In contrast, ech mutation
only marginally perturbs the trafficking of the highly related auxin influx carrier
LIKE-AUX1-3 or the auxin efflux carrier PIN-FORMED-3, both also involved in hook
development. Electron tomography reveals that the trafficking defects in ech mutant
are associated with the perturbation of secretory vesicle genesis from the TGN.
Our results identify differential mechanisms for the post-Golgi trafficking of
de novo-synthesized auxin carriers to plasma membrane from the TGN and reveal
how trafficking of auxin influx carriers mediates the control of differential
cell elongation in apical hook development.

text: Cell-to-cell directional flow of the phytohormone auxin is primarily established
by polar localization of the PIN auxin transporters, a process tightly regulated
at multiple levels by auxin itself. We recently reported that, in the context
of strong auxin flows, activity of the vacuolar ZIFL1.1 transporter is required
for fine-tuning of polar auxin transport rates in the Arabidopsis root. In particular,
ZIFL1.1 function protects plasma-membrane stability of the PIN2 carrier in epidermal
root tip cells under conditions normally triggering PIN2 degradation. Here, we
show that ZIFL1.1 activity at the root tip also promotes PIN1 plasma-membrane
abundance in central cylinder cells, thus supporting the notion that ZIFL1.1 acts
as a general positive modulator of polar auxin transport in roots.

text: 'Intracellular protein routing is mediated by vesicular transport which is
tightly regulated in eukaryotes. The protein and lipid homeostasis depends on
coordinated delivery of de novo synthesized or recycled cargoes to the plasma
membrane by exocytosis and their subsequent removal by rerouting them for recycling
or degradation. Here, we report the characterization of protein affected trafficking
3 (pat3) mutant that we identified by an epifluorescence-based forward genetic
screen for mutants defective in subcellular distribution of Arabidopsis auxin
transporter PIN1–GFP. While pat3 displays largely normal plant morphology and
development in nutrient-rich conditions, it shows strong ectopic intracellular
accumulations of different plasma membrane cargoes in structures that resemble
prevacuolar compartments (PVC) with an aberrant morphology. Genetic mapping revealed
that pat3 is defective in vacuolar protein sorting 35A (VPS35A), a putative subunit
of the retromer complex that mediates retrograde trafficking between the PVC and
trans-Golgi network. Similarly, a mutant defective in another retromer subunit,
vps29, shows comparable subcellular defects in PVC morphology and protein accumulation.
Thus, our data provide evidence that the retromer components VPS35A and VPS29
are essential for normal PVC morphology and normal trafficking of plasma membrane
proteins in plants. In addition, we show that, out of the three VPS35 retromer
subunits present in Arabidopsis thaliana genome, the VPS35 homolog A plays a prevailing
role in trafficking to the lytic vacuole, presenting another level of complexity
in the retromer-dependent vacuolar sorting. '

text: Background:Auxin binding protein 1 (ABP1) is a putative auxin receptor and
its function is indispensable for plant growth and development. ABP1 has been
shown to be involved in auxin-dependent regulation of cell division and expansion,
in plasma-membrane-related processes such as changes in transmembrane potential,
and in the regulation of clathrin-dependent endocytosis. However, the ABP1-regulated
downstream pathway remains elusive.Methodology/Principal Findings:Using auxin
transport assays and quantitative analysis of cellular morphology we show that
ABP1 regulates auxin efflux from tobacco BY-2 cells. The overexpression of ABP1can
counterbalance increased auxin efflux and auxin starvation phenotypes caused by
the overexpression of PIN auxin efflux carrier. Relevant mechanism involves the
ABP1-controlled vesicle trafficking processes, including positive regulation of
endocytosis of PIN auxin efflux carriers, as indicated by fluorescence recovery
after photobleaching (FRAP) and pharmacological manipulations.Conclusions/Significance:The
findings indicate the involvement of ABP1 in control of rate of auxin transport
across plasma membrane emphasizing the role of ABP1 in regulation of PIN activity
at the plasma membrane, and highlighting the relevance of ABP1 for the formation
of developmentally important, PIN-dependent auxin gradients.

text: Plant-specific PIN-formed (PIN) efflux transporters for the plant hormone
auxin are required for tissue-specific directional auxin transport and cellular
auxin homeostasis. The Arabidopsis PIN protein family has been shown to play important
roles in developmental processes such as embryogenesis, organogenesis, vascular
tissue differentiation, root meristem patterning and tropic growth. Here we analyzed
roles of the less characterised Arabidopsis PIN6 auxin transporter. PIN6 is auxin-inducible
and is expressed during multiple auxin-regulated developmental processes. Loss
of pin6 function interfered with primary root growth and lateral root development.
Misexpression of PIN6 affected auxin transport and interfered with auxin homeostasis
in other growth processes such as shoot apical dominance, lateral root primordia
development, adventitious root formation, root hair outgrowth and root waving.
These changes in auxin-regulated growth correlated with a reduction in total auxin
transport as well as with an altered activity of DR5-GUS auxin response reporter.
Overall, the data indicate that PIN6 regulates auxin homeostasis during plant
development.

text: In order to establish a reference for analysis of the function of auxin and
the auxin biosynthesis regulators SHORT INTERNODE/ STYLISH (SHI/STY) during Physcomitrella
patens reproductive development, we have described male (antheridial) and female
(archegonial) development in detail, including temporal and positional information
of organ initiation. This has allowed us to define discrete stages of organ morphogenesis
and to show that reproductive organ development in P. patens is highly organized
and that organ phyllotaxis differs between vegetative and reproductive development.
Using the PpSHI1 and PpSHI2 reporter and knockout lines, the auxin reporters GmGH3pro:GUS
and PpPINApro:GFP-GUS, and the auxin-conjugating transgene PpSHI2pro:IAAL, we
could show that the PpSHI genes, and by inference also auxin, play important roles
for reproductive organ development in moss. The PpSHI genes are required for the
apical opening of the reproductive organs, the final differentiation of the egg
cell, and the progression of canal cells into a cell death program. The apical
cells of the archegonium, the canal cells, and the egg cell are also sites of
auxin responsiveness and are affected by reduced levels of active auxin, suggesting
that auxin mediates PpSHI function in the reproductive organs.

text: Many key aspects of plant development are regulated by the polarized transport
of the phytohormone auxin. Cellular auxin efflux, the rate-limiting step in this
process, has been shown to rely on the coordinated action of PIN-formed (PIN)
and B-type ATP binding cassette (ABCB) carriers. Here, we report that polar auxin
transport in the Arabidopsis thaliana root also requires the action of a Major
Facilitator Superfamily (MFS) transporter, Zinc-Induced Facilitator-Like 1 (ZIFL1).
Sequencing, promoter-reporter, and fluorescent protein fusion experiments indicate
that the full-length ZIFL1.1 protein and a truncated splice isoform, ZIFL1.3,
localize to the tonoplast of root cells and the plasma membrane of leaf stomatal
guard cells, respectively. Using reverse genetics, we show that the ZIFL1.1 transporter
regulates various root auxin-related processes, while the ZIFL1.3 isoform mediates
drought tolerance by regulating stomatal closure. Auxin transport and immunolocalization
assays demonstrate that ZIFL1.1 indirectly modulates cellular auxin efflux during
shootward auxin transport at the root tip, likely by regulating plasma membrane
PIN2 abundance. Finally, heterologous expression in yeast revealed that ZIFL1.1
and ZIFL1.3 share H+-coupled K+ transport activity. Thus, by determining the subcellular
and tissue distribution of two isoforms, alternative splicing dictates a dual
function for the ZIFL1 transporter. We propose that this MFS carrier regulates
stomatal movements and polar auxin transport by modulating potassium and proton
fluxes in Arabidopsis cells.

text: Removal of cargos from the cell surface via endocytosis is an efficient mechanism
to regulate activities of plasma membrane (PM)-resident proteins, such as receptors
or transporters. Salicylic acid (SA) is an important plant hormone that is traditionally
associated with pathogen defense. Here, we describe an unanticipated effect of
SA on subcellular endocytic cycling of proteins. Both exogenous treatments and
endogenously enhanced SA levels repressed endocytosis of different PM proteins.
The SA effect on endocytosis did not involve transcription or known components
of the SA signaling pathway for transcriptional regulation. SA likely targets
an endocytic mechanism that involves the coat protein clathrin, because SA interfered
with the clathrin incidence at the PM and clathrin-deficient mutants were less
sensitive to the impact of SA on the auxin distribution and root bending during
the gravitropic response. By contrast, SA did not affect the ligand-induced endocytosis
of the FLAGELLIN SENSING2 (FLS2) receptor during pathogen responses. Our data
suggest that the established SA impact on transcription in plant immunity and
the nontranscriptional effect of SA on clathrin-mediated endocytosis are independent
mechanisms by which SA regulates distinct aspects of plant physiology.

text: PIN-FORMED (PIN) proteins localize asymmetrically at the plasma membrane and
mediate intercellular polar transport of the plant hormone auxin that is crucial
for a multitude of developmental processes in plants. PIN localization is under
extensive control by environmental or developmental cues, but mechanisms regulating
PIN localization are not fully understood. Here we show that early endosomal components
ARF GEF BEN1 and newly identified Sec1/Munc18 family protein BEN2 are involved
in distinct steps of early endosomal trafficking. BEN1 and BEN2 are collectively
required for polar PIN localization, for their dynamic repolarization, and consequently
for auxin activity gradient formation and auxin-related developmental processes
including embryonic patterning, organogenesis, and vasculature venation patterning.
These results show that early endosomal trafficking is crucial for cell polarity
and auxin-dependent regulation of plant architecture.

text: The phytohormone auxin regulates virtually every aspect of plant development.
To identify new genes involved in auxin activity, a genetic screen was performed
for Arabidopsis (Arabidopsis thaliana) mutants with altered expression of the
auxin-responsive reporter DR5rev:GFP. One of the mutants recovered in the screen,
designated as weak auxin response3 (wxr3), exhibits much lower DR5rev:GFP expression
when treated with the synthetic auxin 2,4-dichlorophenoxyacetic acid and displays
severe defects in root development. The wxr3 mutant decreases polar auxin transport
and results in a disruption of the asymmetric auxin distribution. The levels of
the auxin transporters AUXIN1 and PIN-FORMED are dramatically reduced in the wxr3
root tip. Molecular analyses demonstrate that WXR3 is ROOT ULTRAVIOLET B-SENSITIVE1
(RUS1), a member of the conserved Domain of Unknown Function647 protein family
found in diverse eukaryotic organisms. Our data suggest that RUS1/WXR3 plays an
essential role in the regulation of polar auxin transport by maintaining the proper
level of auxin transporters on the plasma membrane.

text: As soon as a seed germinates, plant growth relates to gravity to ensure that
the root penetrates the soil and the shoot expands aerially. Whereas mechanisms
of positive and negative orthogravitropism of primary roots and shoots are relatively
well understood [1-3], lateral organs often show more complex growth behavior
[4]. Lateral roots (LRs) seemingly suppress positive gravitropic growth and show
a defined gravitropic set-point angle (GSA) that allows radial expansion of the
root system (plagiotropism) [3, 4]. Despite its eminent importance for root architecture,
it so far remains completely unknown how lateral organs partially suppress positive
orthogravitropism. Here we show that the phytohormone auxin steers GSA formation
and limits positive orthogravitropism in LR. Low and high auxin levels/signaling
lead to radial or axial root systems, respectively. At a cellular level, it is
the auxin transport-dependent regulation of asymmetric growth in the elongation
zone that determines GSA. Our data suggest that strong repression of PIN4/PIN7
and transient PIN3 expression limit auxin redistribution in young LR columella
cells. We conclude that PIN activity, by temporally limiting the asymmetric auxin
fluxes in the tip of LRs, induces transient, differential growth responses in
the elongation zone and, consequently, controls root architecture.

text: Gravitropic bending of plant organs is mediated by an asymmetric signaling
of the plant hormone auxin between the upper and lower side of the respective
organ. Here, we show that also another plant hormone, gibberellic acid (GA), shows
asymmetric action during gravitropic responses. Immunodetection using an antibody
against GA and monitoring GA signaling output by downstream degradation of DELLA
proteins revealed an asymmetric GA distribution and response with the maximum
at the lower side of gravistimulated roots. Genetic or pharmacological manipulation
of GA levels or response affects gravity-mediated auxin redistribution and root
bending response. The higher GA levels at the lower side of the root correlate
with increased amounts of PIN-FORMED2 (PIN2) auxin transporter at the plasma membrane.
The observed increase in PIN2 stability is caused by a specific GA effect on trafficking
of PIN proteins to lytic vacuoles that presumably occurs downstream of brefeldin
A-sensitive endosomes. Our results suggest that asymmetric auxin distribution
instructive for gravity-induced differential growth is consolidated by the asymmetric
action of GA that stabilizes the PIN-dependent auxin stream along the lower side
of gravistimulated roots.

text: Plant architecture is influenced by the polar, cell-to-cell transport of auxin
that is primarily provided and regulated by plasma membrane efflux catalysts of
the PIN-FORMED and B family of ABC transporter (ABCB) classes. The latter were
shown to require the functionality of the FK506 binding protein42 TWISTED DWARF1
(TWD1), although underlying mechanisms are unclear. By genetic manipulation of
TWD1 expression, we show here that TWD1 affects shootward root auxin reflux and,
thus, downstream developmental traits, such as epidermal twisting and gravitropism
of the root. Using immunological assays, we demonstrate a predominant lateral,
mainly outward-facing, plasma membrane location for TWD1 in the root epidermis
characterized by the lateral marker ABC transporter G36/PLEIOTROPIC DRUG-RESISTANCE8/PENETRATION3.
At these epidermal plasma membrane domains, TWD1 colocalizes with nonpolar ABCB1.
In planta bioluminescence resonance energy transfer analysis was used to verify
specific ABC transporter B1 (ABCB1)-TWD1 interaction. Our data support a model
in which TWD1 promotes lateral ABCB-mediated auxin efflux via protein-protein
interaction at the plasma membrane, minimizing reflux from the root apoplast into
the cytoplasm.

text: The distribution of the phytohormone auxin regulates many aspects of plant
development including growth response to gravity. Gravitropic root curvature involves
coordinated and asymmetric cell elongation between the lower and upper side of
the root, mediated by differential cellular auxin levels. The asymmetry in the
auxin distribution is established and maintained by a spatio-temporal regulation
of the PIN-FORMED (PIN) auxin transporter activity. We provide novel insights
into the complex regulation of PIN abundance and activity during root gravitropism.
We show that PIN2 turnover is differentially regulated on the upper and lower
side of gravistimulated roots by distinct but partially overlapping auxin feedback
mechanisms. In addition to regulating transcription and clathrin-mediated internalization,
auxin also controls PIN abundance at the plasma membrane by promoting their vacuolar
targeting and degradation. This effect of elevated auxin levels requires the activity
of SKP-Cullin-F-box TIR1/AFB (SCF TIR1/AFB)-dependent pathway. Importantly, also
suboptimal auxin levels mediate PIN degradation utilizing the same signalling
pathway. These feedback mechanisms are functionally important during gravitropic
response and ensure fine-tuning of auxin fluxes for maintaining as well as terminating
asymmetric growth.

text: Fertilization in flowering plants requires the temporal and spatial coordination
of many developmental processes, including pollen production, anther dehiscence,
ovule production, and pollen tube elongation. However, it remains elusive as to
how this coordination occurs during reproduction. Here, we present evidence that
endocytosis, involving heterotetrameric adaptor protein complex 2 (AP-2), plays
a crucial role in fertilization. An Arabidopsis thaliana mutant ap2m displays
multiple defects in pollen production and viability, as well as elongation of
staminal filaments and pollen tubes, all of which are pivotal processes needed
for fertilization. Of these abnormalities, the defects in elongation of staminal
filaments and pollen tubes were partially rescued by exogenous auxin. Moreover,
DR5rev:GFP (for green fluorescent protein) expression was greatly reduced in filaments
and anthers in ap2m mutant plants. At the cellular level, ap2m mutants displayed
defects in both endocytosis of N-(3-triethylammonium-propyl)-4- (4-diethylaminophenylhexatrienyl)
pyridinium dibromide, a lypophilic dye used as an endocytosis marker, and polar
localization of auxin-efflux carrier PIN FORMED2 (PIN2) in the stamen filaments.
Moreover, these defects were phenocopied by treatment with Tyrphostin A23, an
inhibitor of endocytosis. Based on these results, we propose that AP-2-dependent
endocytosis plays a crucial role in coordinating the multiple developmental aspects
of male reproductive organs by modulating cellular auxin level through the regulation
of the amount and polarity of PINs.

text: 'Clathrin-mediated endocytosis (CME) regulates many aspects of plant development,
including hormone signaling and responses to environmental stresses. Despite the
importance of this process, the machinery that regulates CME in plants is largely
unknown. In mammals, the heterotetrameric ADAPTOR PROTEIN COMPLEX-2 (AP-2) is
required for the formation of clathrin-coated vesicles at the plasma membrane
(PM). Although the existence of AP-2 has been predicted in Arabidopsis thaliana,
the biochemistry and functionality of the complex is still uncharacterized. Here,
we identified all the subunits of the Arabidopsis AP-2 by tandem affinity purification
and found that one of the large AP-2 subunits, AP2A1, localized at the PM and
interacted with clathrin. Furthermore, endocytosis of the leucine-rich repeat
receptor kinase, BRASSINOSTEROID INSENSITIVE1 (BRI1), was shown to depend on AP-2.
Knockdown of the two Arabidopsis AP2A genes or overexpression of a dominant-negative
version of the medium AP-2 subunit, AP2M, impaired BRI1 endocytosis and enhanced
the brassinosteroid signaling. Our data reveal that the CME machinery in Arabidopsis
is evolutionarily conserved and that AP-2 functions in receptormediated endocytosis. '

text: The native auxin, indole-3-acetic acid (IAA), is a major regulator of plant
growth and development. Its nonuniform distribution between cells and tissues
underlies the spatiotemporal coordination of many developmental events and responses
to environmental stimuli. The regulation of auxin gradients and the formation
of auxin maxima/minima most likely involve the regulation of both metabolic and
transport processes. In this article, we have demonstrated that 2-oxindole-3-acetic
acid (oxIAA) is a major primary IAA catabolite formed in Arabidopsis thaliana
root tissues. OxIAA had little biological activity and was formed rapidly and
irreversibly in response to increases in auxin levels. We further showed that
there is cell type-specific regulation of oxIAA levels in the Arabidopsis root
apex. We propose that oxIAA is an important element in the regulation of output
from auxin gradients and, therefore, in the regulation of auxin homeostasis and
response mechanisms.

text: In plants, changes in local auxin concentrations can trigger a range of developmental
processes as distinct tissues respond differently to the same auxin stimulus.
However, little is known about how auxin is interpreted by individual cell types.
We performed a transcriptomic analysis of responses to auxin within four distinct
tissues of the Arabidopsis thaliana root and demonstrate that different cell types
show competence for discrete responses. The majority of auxin‐responsive genes
displayed a spatial bias in their induction or repression. The novel data set
was used to examine how auxin influences tissue‐specific transcriptional regulation
of cell‐identity markers. Additionally, the data were used in combination with
spatial expression maps of the root to plot a transcriptomic auxin‐response gradient
across the apical and basal meristem. The readout revealed a strong correlation
for thousands of genes between the relative response to auxin and expression along
the longitudinal axis of the root. This data set and comparative analysis provide
a transcriptome‐level spatial breakdown of the response to auxin within an organ
where this hormone mediates many aspects of development.

text: The apical-basal axis of the early plant embryo determines the body plan of
the adult organism. To establish a polarized embryonic axis, plants evolved a
unique mechanism that involves directional, cell-to-cell transport of the growth
regulator auxin. Auxin transport relies on PIN auxin transporters [1], whose polar
subcellular localization determines the flow directionality. PIN-mediated auxin
transport mediates the spatial and temporal activity of the auxin response machinery
[2-7] that contributes to embryo patterning processes, including establishment
of the apical (shoot) and basal (root) embryo poles [8]. However, little is known
of upstream mechanisms guiding the (re)polarization of auxin fluxes during embryogenesis
[9]. Here, we developed a model of plant embryogenesis that correctly generates
emergent cell polarities and auxin-mediated sequential initiation of apical-basal
axis of plant embryo. The model relies on two precisely localized auxin sources
and a feedback between auxin and the polar, subcellular PIN transporter localization.
Simulations reproduced PIN polarity and auxin distribution, as well as previously
unknown polarization events during early embryogenesis. The spectrum of validated
model predictions suggests that our model corresponds to a minimal mechanistic
framework for initiation and orientation of the apical-basal axis to guide both
embryonic and postembryonic plant development.

text: Establishment of the embryonic axis foreshadows the main body axis of adults
both in plants and in animals, but underlying mechanisms are considered distinct.
Plants utilize directional, cell-to-cell transport of the growth hormone auxin
[1, 2] to generate an asymmetric auxin response that specifies the embryonic apical-basal
axis [3-6]. The auxin flow directionality depends on the polarized subcellular
localization of PIN-FORMED (PIN) auxin transporters [7, 8]. It remains unknown
which mechanisms and spatial cues guide cell polarization and axis orientation
in early embryos. Herein, we provide conceptually novel insights into the formation
of embryonic axis in Arabidopsis by identifying a crucial role of localized tryptophan-dependent
auxin biosynthesis [9-12]. Local auxin production at the base of young embryos
and the accompanying PIN7-mediated auxin flow toward the proembryo are required
for the apical auxin response maximum and the specification of apical embryonic
structures. Later in embryogenesis, the precisely timed onset of localized apical
auxin biosynthesis mediates PIN1 polarization, basal auxin response maximum, and
specification of the root pole. Thus, the tight spatiotemporal control of distinct
local auxin sources provides a necessary, non-cell-autonomous trigger for the
coordinated cell polarization and subsequent apical-basal axis orientation during
embryogenesis and, presumably, also for other polarization events during postembryonic
plant life [13, 14].
