text: Adventitious roots (AR) are de novo formed roots that emerge from any part
of the plant or from callus in tissue culture, except root tissue. The plant tissue
origin and the method by which they are induced determine the physiological properties
of emerged ARs. Hence, a standard method encompassing all types of AR does not
exist. Here we describe a method for the induction and analysis of AR that emerge
from the etiolated hypocotyl of dicot plants. The hypocotyl is formed during embryogenesis
and shows a determined developmental pattern which usually does not involve AR
formation. However, the hypocotyl shows propensity to form de novo roots under
specific circumstances such as removal of the root system, high humidity or flooding,
or during de-etiolation. The hypocotyl AR emerge from a pericycle-like cell layer
surrounding the vascular tissue of the central cylinder, which is reminiscent
to the developmental program of lateral roots. Here we propose an easy protocol
for in vitro hypocotyl AR induction from etiolated Arabidopsis seedlings.

text: Immunolocalization is a valuable tool for cell biology research that allows
to rapidly determine the localization and expression levels of endogenous proteins.
In plants, whole-mount in situ immunolocalization remains a challenging method,
especially in tissues protected by waxy layers and complex cell wall carbohydrates.
Here, we present a robust method for whole-mount in situ immunolocalization in
primary root meristems and lateral root primordia in Arabidopsis thaliana. For
good epitope preservation, fixation is done in an alkaline paraformaldehyde/glutaraldehyde
mixture. This fixative is suitable for detecting a wide range of proteins, including
integral transmembrane proteins and proteins peripherally attached to the plasma
membrane. From initiation until emergence from the primary root, lateral root
primordia are surrounded by several layers of differentiated tissues with a complex
cell wall composition that interferes with the efficient penetration of all buffers.
Therefore, immunolocalization in early lateral root primordia requires a modified
method, including a strong solvent treatment for removal of hydrophobic barriers
and a specific cocktail of cell wall-degrading enzymes. The presented method allows
for easy, reliable, and high-quality in situ detection of the subcellular localization
of endogenous proteins in primary and lateral root meristems without the need
of time-consuming crosses or making translational fusions to fluorescent proteins.

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: The plant hormone gibberellic acid (GA) is a crucial regulator of growth and
development. The main paradigm of GA signaling puts forward transcriptional regulation
via the degradation of DELLA transcriptional repressors. GA has also been shown
to regulate tropic responses by modulation of the plasma membrane incidence of
PIN auxin transporters by an unclear mechanism. Here we uncovered the cellular
and molecular mechanisms by which GA redirects protein trafficking and thus regulates
cell surface functionality. Photoconvertible reporters revealed that GA balances
the protein traffic between the vacuole degradation route and recycling back to
the cell surface. Low GA levels promote vacuolar delivery and degradation of multiple
cargos, including PIN proteins, whereas high GA levels promote their recycling
to the plasma membrane. This GA effect requires components of the retromer complex,
such as Sorting Nexin 1 (SNX1) and its interacting, microtubule (MT)-associated
protein, the Cytoplasmic Linker-Associated Protein (CLASP1). Accordingly, GA regulates
the subcellular distribution of SNX1 and CLASP1, and the intact MT cytoskeleton
is essential for the GA effect on trafficking. This GA cellular action occurs
through DELLA proteins that regulate the MT and retromer presumably via their
interaction partners Prefoldins (PFDs). Our study identified a branching of the
GA signaling pathway at the level of DELLA proteins, which, in parallel to regulating
transcription, also target by a nontranscriptional mechanism the retromer complex
acting at the intersection of the degradation and recycling trafficking routes.
By this mechanism, GA can redirect receptors and transporters to the cell surface,
thus coregulating multiple processes, including PIN-dependent auxin fluxes during
tropic responses.

text: The rapid auxin-triggered growth of the Arabidopsis hypocotyls involves the
nuclear TIR1/AFB-Aux/IAA signaling and is accompanied by acidification of the
apoplast and cell walls (Fendrych et al., 2016). Here, we describe in detail the
method for analysis of the elongation and the TIR1/AFB-Aux/IAA-dependent auxin
response in hypocotyl segments as well as the determination of relative values
of the cell wall pH.

text: Auxin is unique among plant hormones due to its directional transport that
is mediated by the polarly distributed PIN auxin transporters at the plasma membrane.
The canalization hypothesis proposes that the auxin feedback on its polar flow
is a crucial, plant-specific mechanism mediating multiple self-organizing developmental
processes. Here, we used the auxin effect on the PIN polar localization in Arabidopsis
thaliana roots as a proxy for the auxin feedback on the PIN polarity during canalization.
We performed microarray experiments to find regulators of this process that act
downstream of auxin. We identified genes that were transcriptionally regulated
by auxin in an AXR3/IAA17- and ARF7/ARF19-dependent manner. Besides the known
components of the PIN polarity, such as PID and PIP5K kinases, a number of potential
new regulators were detected, among which the WRKY23 transcription factor, which
was characterized in more detail. Gain- and loss-of-function mutants confirmed
a role for WRKY23 in mediating the auxin effect on the PIN polarity. Accordingly,
processes requiring auxin-mediated PIN polarity rearrangements, such as vascular
tissue development during leaf venation, showed a higher WRKY23 expression and
required the WRKY23 activity. Our results provide initial insights into the auxin
transcriptional network acting upstream of PIN polarization and, potentially,
canalization-mediated plant development.

text: 'One of the key questions in understanding plant development is how single
cells behave in a larger context of the tissue. Therefore, it requires the observation
of the whole organ with a high spatial- as well as temporal resolution over prolonged
periods of time, which may cause photo-toxic effects. This protocol shows a plant
sample preparation method for light-sheet microscopy, which is characterized by
mounting the plant vertically on the surface of a gel. The plant is mounted in
such a way that the roots are submerged in a liquid medium while the leaves remain
in the air. In order to ensure photosynthetic activity of the plant, a custom-made
lighting system illuminates the leaves. To keep the roots in darkness the water
surface is covered with sheets of black plastic foil. This method allows long-term
imaging of plant organ development in standardized conditions. '

text: The phytohormone auxin is a major determinant and regulatory component important
for plant development. Auxin transport between cells is mediated by a complex
system of transporters such as AUX1/LAX, PIN, and ABCB proteins, and their localization
and activity is thought to be influenced by phosphatases and kinases. Flavonols
have been shown to alter auxin transport activity and changes in flavonol accumulation
in the Arabidopsis thaliana rol1-2 mutant cause defects in auxin transport and
seedling development. A new mutation in ROOTS CURL IN NPA 1 (RCN1), encoding a
regulatory subunit of the phosphatase PP2A, was found to suppress the growth defects
of rol1-2 without changing the flavonol content. rol1-2 rcn1-3 double mutants
show wild type-like auxin transport activity while levels of free auxin are not
affected by rcn1-3. In the rol1-2 mutant, PIN2 shows a flavonol-induced basal-to-apical
shift in polar localization which is reversed in the rol1-2 rcn1-3 to basal localization.
In vivo analysis of PINOID action, a kinase known to influence PIN protein localization
in a PP2A-antagonistic manner, revealed a negative impact of flavonols on PINOID
activity. Together, these data suggest that flavonols affect auxin transport by
modifying the antagonistic kinase/phosphatase equilibrium.

text: "Plant hormone auxin and its transport between cells belong to the most important\r\nmechanisms
controlling plant development. Auxin itself could change localization of PINs
and\r\nthereby control direction of its own flow. We performed an expression profiling
experiment\r\nin Arabidopsis roots to identify potential regulators of PIN polarity
which are transcriptionally\r\nregulated by auxin signalling. We identified several
novel regulators and performed a detailed\r\ncharacterization of the transcription
factor WRKY23 (At2g47260) and its role in auxin\r\nfeedback on PIN polarity. Gain-of-function
and dominant-negative mutants revealed that\r\nWRKY23 plays a crucial role in
mediating the auxin effect on PIN polarity. In concordance,\r\ntypical polar auxin
transport processes such as gravitropism and leaf vascular pattern\r\nformation
were disturbed by interfering with WRKY23 function.\r\nIn order to identify direct
targets of WRKY23, we performed consequential expression\r\nprofiling experiments
using a WRKY23 inducible gain-of-function line and dominant-negative\r\nWRKY23
line that is defunct in PIN re-arrangement. Among several genes mostly related
to\r\nthe groups of cell wall and defense process regulators, we identified LYSINE-HISTIDINE\r\nTRANSPORTER
1 (LHT1; At5g40780), a small amino acid permease gene from the amino\r\nacid/auxin
permease family (AAAP), we present its detailed characterisation in auxin feedback\r\non
PIN repolarization, identified its transcriptional regulation, we propose a potential\r\nmechanism
of its action. Moreover, we identified also a member of receptor-like protein\r\nkinase
LRR-RLK (LEUCINE-RICH REPEAT TRANSMEMBRANE PROTEIN KINASE PROTEIN 1;\r\nLRRK1;
At1g05700), which also affects auxin-dependent PIN re-arrangement. We described\r\nits
transcriptional behaviour, subcellular localization. Based on global expression
data, we\r\ntried to identify ligand responsible for mechanism of signalling and
suggest signalling partner\r\nand interactors. Additionally, we described role
of novel phytohormone group, strigolactone,\r\nin auxin-dependent PIN re-arrangement,
that could be a fundament for future studies in this\r\nfield.\r\nOur results
provide first insights into an auxin transcriptional network targeting PIN\r\nlocalization
and thus regulating plant development. We highlighted WRKY23 transcriptional\r\nnetwork
and characterised its mediatory role in plant development. We identified direct\r\neffectors
of this network, LHT1 and LRRK1, and describe their roles in PIN re-arrangement
and\r\nPIN-dependent auxin transport processes."

text: Auxin steers numerous physiological processes in plants, making the tight
control of its endogenous levels and spatiotemporal distribution a necessity.
This regulation is achieved by different mechanisms, including auxin biosynthesis,
metabolic conversions, degradation, and transport. Here, we introduce cis-cinnamic
acid (c-CA) as a novel and unique addition to a small group of endogenous molecules
affecting in planta auxin concentrations. c-CA is the photo-isomerization product
of the phenylpropanoid pathway intermediate trans-CA (t-CA). When grown on c-CA-containing
medium, an evolutionary diverse set of plant species were shown to exhibit phenotypes
characteristic for high auxin levels, including inhibition of primary root growth,
induction of root hairs, and promotion of adventitious and lateral rooting. By
molecular docking and receptor binding assays, we showed that c-CA itself is neither
an auxin nor an anti-auxin, and auxin profiling data revealed that c-CA does not
significantly interfere with auxin biosynthesis. Single cell-based auxin accumulation
assays showed that c-CA, and not t-CA, is a potent inhibitor of auxin efflux.
Auxin signaling reporters detected changes in spatiotemporal distribution of the
auxin response along the root of c-CA-treated plants, and long-distance auxin
transport assays showed no inhibition of rootward auxin transport. Overall, these
results suggest that the phenotypes of c-CA-treated plants are the consequence
of a local change in auxin accumulation, induced by the inhibition of auxin efflux.
This work reveals a novel mechanism how plants may regulate auxin levels and adds
a novel, naturally occurring molecule to the chemical toolbox for the studies
of auxin homeostasis.

text: Membrane traffic at the trans-Golgi network (TGN) is crucial for correctly
distributing various membrane proteins to their destination. Polarly localized
auxin efflux proteins, including PIN-FORMED1 (PIN1), are dynamically transported
between the endosomes and the plasma membrane (PM) in the plant cells. The intracellular
trafficking of PIN1 protein is sensitive to a fungal toxin brefeldin A (BFA),
which is known to inhibit guanine-nucleotide exchange factors for ADP ribosylation
factors (ARF GEFs) such as GNOM. However, the molecular details of the BFA-sensitive
trafficking pathway have not been revealed fully. In a previous study, we have
identified an Arabidopsis mutant BFA-visualized endocytic trafficking defective
3 (ben3) which exhibited reduced sensitivity to BFA in terms of BFA-induced intracellular
PIN1 agglomeration. Here, we show that BEN3 encodes a member of BIG family ARF
GEFs, BIG2. Fluorescent proteins tagged BEN3/BIG2 co-localized with markers for
TGN / early endosome (EE). Inspection of conditionally induced de novo synthesized
PIN1 confirmed that its secretion to the PM is BFA-sensitive and established BEN3/BIG2
as a crucial component of this BFA action at the level of TGN/EE. Furthermore,
ben3 mutation alleviated BFA-induced agglomeration of another TGN-localized ARF
GEF BEN1/MIN7. Taken together our results suggest that BEN3/BIG2 is an ARF GEF
component, which confers BFA sensitivity to the TGN/EE in Arabidopsis.

text: 'The exocyst, a eukaryotic tethering complex, coregulates targeted exocytosis
as an effector of small GTPases in polarized cell growth. In land plants, several
exocyst subunits are encoded by double or triple paralogs, culminating in tens
of EXO70 paralogs. Out of 23 Arabidopsis thaliana EXO70 isoforms, we analyzed
seven isoforms expressed in pollen. Genetic and microscopic analyses of single
mutants in EXO70A2, EXO70C1, EXO70C2, EXO70F1, EXO70H3, EXO70H5, and EXO70H6 genes
revealed that only a loss-of-function EXO70C2 allele resulted in a significant
male-specific transmission defect (segregation 40%:51%:9%) due to aberrant pollen
tube growth. Mutant pollen tubes grown in vitro exhibited an enhanced growth rate
and a decreased thickness of the tip cell wall, causing tip bursts. However, exo70C2
pollen tubes could frequently recover and restart their speedy elongation, resulting
in a repetitive stop-and-go growth dynamics. A pollenspecific depletion of the
closest paralog, EXO70C1, using artificial microRNA in the exo70C2 mutant background,
resulted in a complete pollen-specific transmission defect, suggesting redundant
functions of EXO70C1 and EXO70C2. Both EXO70C1 and EXO70C2, GFP tagged and expressed
under the control of their native promoters, localized in the cytoplasm of pollen
grains, pollen tubes, and also root trichoblast cells. The expression of EXO70C2-GFP
complemented the aberrant growth of exo70C2 pollen tubes. The absent EXO70C2 interactions
with core exocyst subunits in the yeast two-hybrid assay, cytoplasmic localization,
and genetic effect suggest an unconventional EXO70 function possibly as a regulator
of exocytosis outside the exocyst complex. In conclusion, EXO70C2 is a novel factor
contributing to the regulation of optimal tip growth of Arabidopsis pollen tubes. '

text: Plants are sessile organisms rooted in one place. The soil resources that
plants require are often distributed in a highly heterogeneous pattern. To aid
foraging, plants have evolved roots whose growth and development are highly responsive
to soil signals. As a result, 3D root architecture is shaped by myriad environmental
signals to ensure resource capture is optimised and unfavourable environments
are avoided. The first signals sensed by newly germinating seeds — gravity and
light — direct root growth into the soil to aid seedling establishment. Heterogeneous
soil resources, such as water, nitrogen and phosphate, also act as signals that
shape 3D root growth to optimise uptake. Root architecture is also modified through
biotic interactions that include soil fungi and neighbouring plants. This developmental
plasticity results in a ‘custom-made’ 3D root system that is best adapted to forage
for resources in each soil environment that a plant colonises.

text: Development of vascular tissue is a remarkable example of intercellular communication
and coordinated development involving hormonal signaling and tissue polarity.
Thus far, studies on vascular patterning and regeneration have been conducted
mainly in trees—woody plants—with a well-developed layer of vascular cambium and
secondary tissues. Trees are difficult to use as genetic models, i.e., due to
long generation time, unstable environmental conditions, and lack of available
mutants and transgenic lines. Therefore, the use of the main genetic model plant
Arabidopsis thaliana (L.) Heynh., with a wealth of available marker and transgenic
lines, provides a unique opportunity to address molecular mechanism of vascular
tissue formation and regeneration. With specific treatments, the tiny weed Arabidopsis
can serve as a model to understand the growth of mighty trees and interconnect
a tree physiology with molecular genetics and cell biology of Arabidopsis.

text: "One of the key questions in understanding plant development is how single
cells behave in a larger context of the tissue. Therefore, it requires the observation
of the whole organ with a high spatial- as well as temporal resolution over prolonged
periods of time, which may cause photo-toxic effects. This protocol shows a plant
sample preparation method for light-sheet microscopy, which is characterized by
mounting the plant vertically on the surface of a gel. The plant is mounted in
such a way that the roots are submerged in a liquid medium while the leaves remain
in the air. In order to ensure photosynthetic activity of the plant, a custom-made
lighting system illuminates the leaves. To keep the roots in darkness the water
surface is covered with sheets of black plastic foil. This method allows long-term
imaging of plant organ development in standardized conditions. \r\nThe Video is

text: In this review, we summarize the different biosynthesis-related pathways that
contribute to the regulation of endogenous auxin in plants. We demonstrate that
all known genes involved in auxin biosynthesis also have a role in root formation,
from the initiation of a root meristem during embryogenesis to the generation
of a functional root system with a primary root, secondary lateral root branches
and adventitious roots. Furthermore, the versatile adaptation of root development
in response to environmental challenges is mediated by both local and distant
control of auxin biosynthesis. In conclusion, auxin homeostasis mediated by spatial
and temporal regulation of auxin biosynthesis plays a central role in determining
root architecture.

text: Plant organs are typically organized into three main tissue layers. The middle
ground tissue layer comprises the majority of the plant body and serves a wide
range of functions, including photosynthesis, selective nutrient uptake and storage,
and gravity sensing. Ground tissue patterning and maintenance in Arabidopsis are
controlled by a well-established gene network revolving around the key regulator
SHORT-ROOT (SHR). In contrast, it is completely unknown how ground tissue identity
is first specified from totipotent precursor cells in the embryo. The plant signaling
molecule auxin, acting through AUXIN RESPONSE FACTOR (ARF) transcription factors,
is critical for embryo patterning. The auxin effector ARF5/MONOPTEROS (MP) acts
both cell-autonomously and noncell-autonomously to control embryonic vascular
tissue formation and root initiation, respectively. Here we show that auxin response
and ARF activity cell-autonomously control the asymmetric division of the first
ground tissue cells. By identifying embryonic target genes, we show that MP transcriptionally
initiates the ground tissue lineage and acts upstream of the regulatory network
that controls ground tissue patterning and maintenance. Strikingly, whereas the
SHR network depends on MP, this MP function is, at least in part, SHR independent.
Our study therefore identifies auxin response as a regulator of ground tissue
specification in the embryonic root, and reveals that ground tissue initiation
and maintenance use different regulators and mechanisms. Moreover, our data provide
a framework for the simultaneous formation of multiple cell types by the same
transcriptional regulator.

text: The thesis encompasses several topics of plant cell biology which were studied
in the model plant Arabidopsis thaliana. Chapter 1 concerns the plant hormone
auxin and its polar transport through cells and tissues. The highly controlled,
directional transport of auxin is facilitated by plasma membrane-localized transporters.
Transporters from the PIN family direct auxin transport due to their polarized
localizations at cell membranes. Substantial effort has been put into research
on cellular trafficking of PIN proteins, which is thought to underlie their polar
distribution. I participated in a forward genetic screen aimed at identifying
novel regulators of PIN polarity. The screen yielded several genes which may be
involved in PIN polarity regulation or participate in polar auxin transport by
other means. Chapter 2 focuses on the endomembrane system, with particular attention
to clathrin-mediated endocytosis. The project started with identification of several
proteins that interact with clathrin light chains. Among them, I focused on two
putative homologues of auxilin, which in non-plant systems is an endocytotic factor
known for uncoating clathrin-coated vesicles in the final step of endocytosis.
The body of my work consisted of an in-depth characterization of transgenic A.
thaliana lines overexpressing these putative auxilins in an inducible manner.
Overexpression of these proteins leads to an inhibition of endocytosis, as documented
by imaging of cargoes and clathrin-related endocytic machinery. An extension of
this work is an investigation into a concept of homeostatic regulation acting
between distinct transport processes in the endomembrane system. With auxilin
overexpressing lines, where endocytosis is blocked specifically, I made observations
on the mutual relationship between two opposite trafficking processes of secretion
and endocytosis. In Chapter 3, I analyze cortical microtubule arrays and their
relationship to auxin signaling and polarized growth in elongating cells. In plants,
microtubules are organized into arrays just below the plasma membrane, and it
is thought that their function is to guide membrane-docked cellulose synthase
complexes. These, in turn, influence cell wall structure and cell shape by directed
deposition of cellulose fibres. In elongating cells, cortical microtubule arrays
are able to reorient in relation to long cell axis, and these reorientations have
been linked to cell growth and to signaling of growth-regulating factors such
as auxin or light. In this chapter, I am addressing the causal relationship between
microtubule array reorientation, growth, and auxin signaling. I arrive at a model
where array reorientation is not guided by auxin directly, but instead is only
controlled by growth, which, in turn, is regulated by auxin.

text: Roots navigate through soil integrating environmental signals to orient their
growth. The Arabidopsis root is a widely used model for developmental, physiological
and cell biological studies. Live imaging greatly aids these efforts, but the
horizontal sample position and continuous root tip displacement present significant
difficulties. Here, we develop a confocal microscope setup for vertical sample
mounting and integrated directional illumination. We present TipTracker – a custom
software for automatic tracking of diverse moving objects usable on various microscope
setups. Combined, this enables observation of root tips growing along the natural
gravity vector over prolonged periods of time, as well as the ability to induce
rapid gravity or light stimulation. We also track migrating cells in the developing
zebrafish embryo, demonstrating the utility of this system in the acquisition
of high-resolution data sets of dynamic samples. We provide detailed descriptions
of the tools enabling the easy implementation on other microscopes.

text: The asymmetric localization of proteins in the plasma membrane domains of
eukaryotic cells is a fundamental manifestation of cell polarity that is central
to multicellular organization and developmental patterning. In plants, the mechanisms
underlying the polar localization of cargo proteins are still largely unknown
and appear to be fundamentally distinct from those operating in mammals. Here,
we present a systematic, quantitative comparative analysis of the polar delivery
and subcellular localization of proteins that characterize distinct polar plasma
membrane domains in plant cells. The combination of microscopic analyses and computational
modeling revealed a mechanistic framework common to diverse polar cargos and underlying
the establishment and maintenance of apical, basal, and lateral polar domains
in plant cells. This mechanism depends on the polar secretion, constitutive endocytic
recycling, and restricted lateral diffusion of cargos within the plasma membrane.
Moreover, our observations suggest that polar cargo distribution involves the
individual protein potential to form clusters within the plasma membrane and interact
with the extracellular matrix. Our observations provide insights into the shared
cellular mechanisms of polar cargo delivery and polarity maintenance in plant
cells.
