text: Gravitropism is a fundamental adaptive response in plants that enables directional
growth to optimize resource acquisition. In this study, we employed forward genetic
screening to identify Arabidopsis mutants with defective hypocotyl gravitropism
and isolated the short and agravitropic hypocotyl in dark1 (sad1) mutant, which
carries a point mutation (G110E) in the SAC1 gene encoding a phosphoinositide
phosphatase. Deficiency of SAC1 disrupted gravity-induced polar localization of
PIN3 in endodermal cells, impairing auxin redistribution and leading to hypocotyl
gravitropism defects. Subcellular localization analysis revealed that SAC1 is
partially localized to the PVC/tonoplast and participates in late endosomal trafficking.
The sac1 mutation leads to abnormal vacuolar morphology, which is associated with
defects in amyloplast sedimentation during the gravitropic response in Arabidopsis
shoots. We further revealed that SAC1 interacts with GRV2, a key regulator of
the late endocytic pathway, and that both proteins cooperatively regulate shoot
gravitropism. In summary, this study identified SAC1 as a regulator of shoot gravitropism,
revealing its important role in modulating vacuolar homeostasis, amyloplast sedimentation,
PIN3 trafficking, and auxin distribution. These findings provide insights into
the molecular mechanisms linking membrane transport to environmental adaptation
in plants.

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: Brassinosteroids are steroidal phytohormones that regulate plant development
and physiology, including adaptation to environmental stresses. Brassinosteroids
are synthesized in the cell interior but bind receptors at the cell surface, necessitating
a yet to be identified export mechanism. Here, we show that a member of the ATP-binding
cassette (ABC) transporter superfamily, ABCB19, functions as a brassinosteroid
exporter. We present its structure in both the substrate-unbound and the brassinosteroid-bound
states. Bioactive brassinosteroids are potent activators of ABCB19 ATP hydrolysis
activity, and transport assays showed that ABCB19 transports brassinosteroids.
In Arabidopsis thaliana, ABCB19 and its close homolog, ABCB1, positively regulate
brassinosteroid responses. Our results uncover an elusive export mechanism for
bioactive brassinosteroids that is tightly coordinated with brassinosteroid signaling.

text: The developmental plasticity of the root system plays an essential role in
the adaptation of plants to the environment. Among many other signals, auxin and
its directional, intercellular transport are critical in regulating root growth
and development. In particular, the PIN-FORMED2 (PIN2) auxin exporter acts as
a key regulator of root gravitropic growth. Multiple regulators have been reported
to be involved in PIN2-mediated root growth; however, our information remains
incomplete. Here, we identified ROWY Bro1-domain proteins as important regulators
of PIN2 sorting control. Genetic analysis revealed that Arabidopsis rowy1 single
mutants and higher-order rowy1 rowy2 rowy3 triple mutants presented a wavy root
growth phenotype. Cell biological experiments revealed that ROWY1 and PIN2 colocalized
to the apical side of the plasma membrane in the root epidermis and that ROWYs
are required for correct PM targeting of PIN2. In addition, ROWYs also affected
PIN3 protein abundance in the stele, suggesting the potential involvement of additional
PIN transporters as well as other proteins. A global transcriptome analysis revealed
that ROWY genes are involved in the Fe2+ availability perception pathway. This
work establishes ROWYs as important novel regulators of root gravitropic growth
by connecting micronutrient availability to the proper subcellular targeting of
PIN auxin transporters.

text: Lateral roots are typically maintained at non-vertical angles with respect
to gravity. These gravitropic setpoint angles are intriguing because their maintenance
requires that roots are able to effect growth response both with and against the
gravity vector, a phenomenon previously attributed to gravitropism acting against
an antigravitropic offset mechanism. Here we show how the components mediating
gravitropism in the vertical primary root—PINs and phosphatases acting upon them—are
reconfigured in their regulation such that lateral root growth at a range of angles
can be maintained. We show that the ability of Arabidopsis lateral roots to bend
both downward and upward requires the generation of auxin asymmetries and is driven
by angle-dependent variation in downward gravitropic auxin flux acting against
angle-independent upward, antigravitropic flux. Further, we demonstrate a symmetry
in auxin distribution in lateral roots at gravitropic setpoint angle that can
be traced back to a net, balanced polarization of PIN3 and PIN7 auxin transporters
in the columella. These auxin fluxes are shifted by altering PIN protein phosphoregulation
in the columella, either by introducing PIN3 phosphovariant versions or via manipulation
of levels of the phosphatase subunit PP2A/RCN1. Finally, we show that auxin, in
addition to driving lateral root directional growth, acts within the lateral root
columella to induce more vertical growth by increasing RCN1 levels, causing a
downward shift in PIN3 localization, thereby diminishing the magnitude of the
upward, antigravitropic auxin flux.

text: Directionality in the intercellular transport of the plant hormone auxin is
determined by polar plasma membrane localization of PIN-FORMED (PIN) auxin transport
proteins. However, apart from PIN phosphorylation at conserved motifs, no further
determinants explicitly controlling polar PIN sorting decisions have been identified.
Here we present Arabidopsis WAVY GROWTH 3 (WAV3) and closely related RING-finger
E3 ubiquitin ligases, whose loss-of-function mutants show a striking apical-to-basal
polarity switch in PIN2 localization in root meristem cells. WAV3 E3 ligases function
as essential determinants for PIN polarity, acting independently from PINOID/WAG-dependent
PIN phosphorylation. They antagonize ectopic deposition of de novo synthesized
PIN proteins already immediately following completion of cell division, presumably
via preventing PIN sorting into basal, ARF GEF-mediated trafficking. Our findings
reveal an involvement of E3 ligases in the selective targeting of apically localized
PINs in higher plants.

text: Among the most fascinated properties of the plant hormone auxin is its ability
to promote formation of its own directional transport routes. These gradually
narrowing auxin channels form from the auxin source toward the sink and involve
coordinated, collective polarization of individual cells. Once established, the
channels provide positional information, along which new vascular strands form,
for example, during organogenesis, regeneration, or leave venation. The main prerequisite
of this still mysterious auxin canalization mechanism is a feedback between auxin
signaling and its directional transport. This is manifested by auxin-induced re-arrangements
of polar, subcellular localization of PIN-FORMED (PIN) auxin exporters. Immanent
open questions relate to how position of auxin source and sink as well as tissue
context are sensed and translated into tissue polarization and how cells communicate
to polarize coordinately. Recently, identification of the first molecular players
opens new avenues into molecular studies of this intriguing example of self-organizing
plant development.

In addition, exciting topics such as PIN polarization in context of phyllotaxis,
shoot branching and termination of gravitropic bending, or role of additional auxin
transporters could not have been included owing to lack of space. This work was

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: "Cell and tissue polarization is fundamental for plant growth and morphogenesis.
The polar, cellular localization of Arabidopsis PIN‐FORMED (PIN) proteins is crucial
for their function in directional auxin transport. The clustering of PIN polar
cargoes within the plasma membrane has been proposed to be important for the maintenance
of their polar distribution. However, the more detailed features of PIN clusters
and the cellular requirements of cargo clustering remain unclear.\r\nHere, we
characterized PIN clusters in detail by means of multiple advanced microscopy
and quantification methods, such as 3D quantitative imaging or freeze‐fracture
replica labeling. The size and aggregation types of PIN clusters were determined
by electron microscopy at the nanometer level at different polar domains and at
different developmental stages, revealing a strong preference for clustering at
the polar domains.\r\nPharmacological and genetic studies revealed that PIN clusters
depend on phosphoinositol pathways, cytoskeletal structures and specific cell‐wall
components as well as connections between the cell wall and the plasma membrane.\r\nThis
study identifies the role of different cellular processes and structures in polar
cargo clustering and provides initial mechanistic insight into the maintenance
of polarity in plants and other systems."

text: To adapt to the diverse array of biotic and abiotic cues, plants have evolved
sophisticated mechanisms to sense changes in environmental conditions and modulate
their growth. Growth-promoting hormones and defence signalling fine tune plant
development antagonistically. During host-pathogen interactions, this defence-growth
trade-off is mediated by the counteractive effects of the defence hormone salicylic
acid (SA) and the growth hormone auxin. Here we revealed an underlying mechanism
of SA regulating auxin signalling by constraining the plasma membrane dynamics
of PIN2 auxin efflux transporter in Arabidopsis thaliana roots. The lateral diffusion
of PIN2 proteins is constrained by SA signalling, during which PIN2 proteins are
condensed into hyperclusters depending on REM1.2-mediated nanodomain compartmentalisation.
Furthermore, membrane nanodomain compartmentalisation by SA or Remorin (REM) assembly
significantly suppressed clathrin-mediated endocytosis. Consequently, SA-induced
heterogeneous surface condensation disrupted asymmetric auxin distribution and
the resultant gravitropic response. Our results demonstrated a defence-growth
trade-off mechanism by which SA signalling crosstalked with auxin transport by
concentrating membrane-resident PIN2 into heterogeneous compartments.

text: The phytohormone auxin plays a central role in shaping plant growth and development.
With decades of genetic and biochemical studies, numerous core molecular components
and their networks, underlying auxin biosynthesis, transport, and signaling, have
been identified. Notably, protein phosphorylation, catalyzed by kinases and oppositely
hydrolyzed by phosphatases, has been emerging to be a crucial type of post-translational
modification, regulating physiological and developmental auxin output at all levels.
In this review, we comprehensively discuss earlier and recent advances in our
understanding of genetics, biochemistry, and cell biology of the kinases and phosphatases
participating in auxin action. We provide insights into the mechanisms by which
reversible protein phosphorylation defines developmental auxin responses, discuss
current challenges, and provide our perspectives on future directions involving
the integration of the control of protein phosphorylation into the molecular auxin
network.

text: Polar subcellular localization of the PIN exporters of the phytohormone auxin
is a key determinant of directional, intercellular auxin transport and thus a
central topic of both plant cell and developmental biology. Arabidopsis mutants
lacking PID, a kinase that phosphorylates PINs, or the MAB4/MEL proteins of unknown
molecular function display PIN polarity defects and phenocopy pin mutants, but
mechanistic insights into how these factors convey PIN polarity are missing. Here,
by combining protein biochemistry with quantitative live-cell imaging, we demonstrate
that PINs, MAB4/MELs, and AGC kinases interact in the same complex at the plasma
membrane. MAB4/MELs are recruited to the plasma membrane by the PINs and in concert
with the AGC kinases maintain PIN polarity through limiting lateral diffusion-based
escape of PINs from the polar domain. The PIN-MAB4/MEL-PID protein complex has
self-reinforcing properties thanks to positive feedback between AGC kinase-mediated
PIN phosphorylation and MAB4/MEL recruitment. We thus uncover the molecular mechanism
by which AGC kinases and MAB4/MEL proteins regulate PIN localization and plant
development.

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: Availability of the essential macronutrient nitrogen in soil plays a critical
role in plant growth, development, and impacts agricultural productivity. Plants
have evolved different strategies for sensing and responding to heterogeneous
nitrogen distribution. Modulation of root system architecture, including primary
root growth and branching, is among the most essential plant adaptions to ensure
adequate nitrogen acquisition. However, the immediate molecular pathways coordinating
the adjustment of root growth in response to distinct nitrogen sources, such as
nitrate or ammonium, are poorly understood. Here, we show that growth as manifested
by cell division and elongation is synchronized by coordinated auxin flux between
two adjacent outer tissue layers of the root. This coordination is achieved by
nitrate‐dependent dephosphorylation of the PIN2 auxin efflux carrier at a previously
uncharacterized phosphorylation site, leading to subsequent PIN2 lateralization
and thereby regulating auxin flow between adjacent tissues. A dynamic computer
model based on our experimental data successfully recapitulates experimental observations.
Our study provides mechanistic insights broadening our understanding of root growth
mechanisms in dynamic environments.

text: Directional intercellular transport of the phytohormone auxin mediated by
PIN FORMED (PIN) efflux carriers plays essential roles in both coordinating patterning
processes and integrating multiple external cues by rapidly redirecting auxin
fluxes. Multilevel regulations of PIN activity under internal and external cues
are complicated; however, the underlying molecular mechanism remains elusive.
Here we demonstrate that 3’-Phosphoinositide-Dependent Protein Kinase1 (PDK1),
which is conserved in plants and mammals, functions as a molecular hub integrating
the upstream lipid signalling and the downstream substrate activity through phosphorylation.
Genetic analysis uncovers that loss-of-function Arabidopsis mutant pdk1.1 pdk1.2
exhibits a plethora of abnormalities in organogenesis and growth, due to the defective
PIN-dependent auxin transport. Further cellular and biochemical analyses reveal
that PDK1 phosphorylates D6 Protein Kinase to facilitate its activity towards
PIN proteins. Our studies establish a lipid-dependent phosphorylation cascade
connecting membrane composition-based cellular signalling with plant growth and
patterning by regulating morphogenetic auxin fluxes.

text: Cell polarity is a fundamental feature of all multicellular organisms. In
plants, prominent cell polarity markers are PIN auxin transporters crucial for
plant development. To identify novel components involved in cell polarity establishment
and maintenance, we carried out a forward genetic screening with PIN2:PIN1-HA;pin2
Arabidopsis plants, which ectopically express predominantly basally localized
PIN1 in the root epidermal cells leading to agravitropic root growth. From the
screen, we identified the regulator of PIN polarity 12 (repp12) mutation, which
restored gravitropic root growth and caused PIN1-HA polarity switch from basal
to apical side of root epidermal cells. Complementation experiments established
the repp12 causative mutation as an amino acid substitution in Aminophospholipid
ATPase3 (ALA3), a phospholipid flippase with predicted function in vesicle formation.
ala3 T-DNA mutants show defects in many auxin-regulated processes, in asymmetric
auxin distribution and in PIN trafficking. Analysis of quintuple and sextuple
mutants confirmed a crucial role of ALA proteins in regulating plant development
and in PIN trafficking and polarity. Genetic and physical interaction studies
revealed that ALA3 functions together with GNOM and BIG3 ARF GEFs. Taken together,
our results identified ALA3 flippase as an important interactor and regulator
of ARF GEF functioning in PIN polarity, trafficking and auxin-mediated development.

text: Spontaneously arising channels that transport the phytohormone auxin provide
positional cues for self-organizing aspects of plant development such as flexible
vasculature regeneration or its patterning during leaf venation. The auxin canalization
hypothesis proposes a feedback between auxin signaling and transport as the underlying
mechanism, but molecular players await discovery. We identified part of the machinery
that routes auxin transport. The auxin-regulated receptor CAMEL (Canalization-related
Auxin-regulated Malectin-type RLK) together with CANAR (Canalization-related Receptor-like
kinase) interact with and phosphorylate PIN auxin transporters. camel and canar
mutants are impaired in PIN1 subcellular trafficking and auxin-mediated PIN polarization,
which macroscopically manifests as defects in leaf venation and vasculature regeneration
after wounding. The CAMEL-CANAR receptor complex is part of the auxin feedback
that coordinates polarization of individual cells during auxin canalization.

text: The widely used non-steroidal anti-inflammatory drugs (NSAIDs) are derivatives
of the phytohormone salicylic acid (SA). SA is well known to regulate plant immunity
and development, whereas there have been few reports focusing on the effects of
NSAIDs in plants. Our studies here reveal that NSAIDs exhibit largely overlapping
physiological activities to SA in the model plant Arabidopsis. NSAID treatments
lead to shorter and agravitropic primary roots and inhibited lateral root organogenesis.
Notably, in addition to the SA-like action, which in roots involves binding to
the protein phosphatase 2A (PP2A), NSAIDs also exhibit PP2A-independent effects.
Cell biological and biochemical analyses reveal that many NSAIDs bind directly
to and inhibit the chaperone activity of TWISTED DWARF1, thereby regulating actin
cytoskeleton dynamics and subsequent endosomal trafficking. Our findings uncover
an unexpected bioactivity of human pharmaceuticals in plants and provide insights
into the molecular mechanism underlying the cellular action of this class of anti-inflammatory
compounds.
