text: 'Cell polarity is crucial for the coordinated development of all multicellular
organisms. In plants, this is exemplified by the PIN-FORMED (PIN) efflux carriers
of the phytohormone auxin: The polar subcellular localization of the PINs is instructive
to the directional intercellular auxin transport, and thus to a plethora of auxin-regulated
growth and developmental processes. Despite its importance, the regulation of
PIN polar subcellular localization remains poorly understood. Here, we have employed
advanced live-cell imaging techniques to study the roles of microtubules and actin
microfilaments in the establishment of apical polar localization of PIN2 in the
epidermis of the Arabidopsis root meristem. We report that apical PIN2 polarity
requires neither intact actin microfilaments nor microtubules, suggesting that
the primary spatial cue for polar PIN distribution is likely independent of cytoskeleton-guided
endomembrane trafficking.'

text: "An important adaptation during colonization of land by plants is gravitropic
growth of roots, which enabled roots to reach water and nutrients, and firmly
anchor plants in the ground. Here we provide insights into the evolution of an
efficient root gravitropic mechanism in the seed plants. Architectural innovation,
with gravity perception constrained in the root tips\r\nalong with a shootward
transport route for the phytohormone auxin, appeared only upon the emergence of
seed plants. Interspecies complementation and protein domain swapping revealed
functional innovations within the PIN family of auxin transporters leading to
the evolution of gravitropism-specific PINs. The unique apical/shootward subcellular
localization of PIN proteins is the major evolutionary innovation that connected
the anatomically separated sites of gravity perception and growth response via
the mobile auxin signal. We conclude that the crucial anatomical and functional
components emerged hand-in-hand to facilitate the evolution of fast gravitropic
response, which is one of the major adaptations of seed plants to dry land."

text: Plants have a remarkable capacity to adjust their growth and development to
elevated ambient temperatures. Increased elongation growth of roots, hypocotyls
and petioles in warm temperatures are hallmarks of seedling thermomorphogenesis.
In the last decade, significant progress has been made to identify the molecular
signaling components regulating these growth responses. Increased ambient temperature
utilizes diverse components of the light sensing and signal transduction network
to trigger growth adjustments. However, it remains unknown whether temperature
sensing and responses are universal processes that occur uniformly in all plant
organs. Alternatively, temperature sensing may be confined to specific tissues
or organs, which would require a systemic signal that mediates responses in distal
parts of the plant. Here we show that Arabidopsis (Arabidopsis thaliana) seedlings
show organ-specific transcriptome responses to elevated temperatures, and that
thermomorphogenesis involves both autonomous and organ-interdependent temperature
sensing and signaling. Seedling roots can sense and respond to temperature in
a shoot-independent manner, whereas shoot temperature responses require both local
and systemic processes. The induction of cell elongation in hypocotyls requires
temperature sensing in cotyledons, followed by generation of a mobile auxin signal.
Subsequently, auxin travels to the hypocotyl where it triggers local brassinosteroid-induced
cell elongation in seedling stems, which depends upon a distinct, permissive temperature
sensor in the hypocotyl.

text: The plant hormone auxin has crucial roles in almost all aspects of plant growth
and development. Concentrations of auxin vary across different tissues, mediating
distinct developmental outcomes and contributing to the functional diversity of
auxin. However, the mechanisms that underlie these activities are poorly understood.
Here we identify an auxin signalling mechanism, which acts in parallel to the
canonical auxin pathway based on the transport inhibitor response1 (TIR1) and
other auxin receptor F-box (AFB) family proteins (TIR1/AFB receptors)1,2, that
translates levels of cellular auxin to mediate differential growth during apical-hook
development. This signalling mechanism operates at the concave side of the apical
hook, and involves auxin-mediated C-terminal cleavage of transmembrane kinase
1 (TMK1). The cytosolic and nucleus-translocated C terminus of TMK1 specifically
interacts with and phosphorylates two non-canonical transcriptional repressors
of the auxin or indole-3-acetic acid (Aux/IAA) family (IAA32 and IAA34), thereby
regulating ARF transcription factors. In contrast to the degradation of Aux/IAA
transcriptional repressors in the canonical pathway, the newly identified mechanism
stabilizes the non-canonical IAA32 and IAA34 transcriptional repressors to regulate
gene expression and ultimately inhibit growth. The auxin–TMK1 signalling pathway
originates at the cell surface, is triggered by high levels of auxin and shares
a partially overlapping set of transcription factors with the TIR1/AFB signalling
pathway. This allows distinct interpretations of different concentrations of cellular
auxin, and thus enables this versatile signalling molecule to mediate complex
developmental outcomes.

text: PIN-FORMED (PIN) transporters mediate directional, intercellular movement
of the phytohormone auxin in land plants. To elucidate the evolutionary origins
of this developmentally crucial mechanism, we analysed the single PIN homologue
of a simple green alga Klebsormidium flaccidum. KfPIN functions as a plasma membrane-localized
auxin exporter in land plants and heterologous models. While its role in algae
remains unclear, PIN-driven auxin export is probably an ancient and conserved
trait within streptophytes.

text: Roots grow downwards parallel to the gravity vector, to anchor a plant in
soil and acquire water and nutrients, using a gravitropic mechanism dependent
on the asymmetric distribution of the phytohormone auxin. Recently, Chang et al.
demonstrate that asymmetric distribution of another phytohormone, cytokinin, directs
root growth towards higher water content.

text: During infection pathogens secrete small molecules, termed effectors, to manipulate
and control the interaction with their specific hosts. Both the pathogen and the
plant are under high selective pressure to rapidly adapt and co-evolve in what
is usually referred to as molecular arms race. Components of the host’s immune
system form a network that processes information about molecules with a foreign
origin and damage-associated signals, integrating them with developmental and
abiotic cues to adapt the plant’s responses. Both in the case of nucleotide-binding
leucine-rich repeat receptors and leucine-rich repeat receptor kinases interaction
networks have been extensively characterized. However, little is known on whether
pathogenic effectors form complexes to overcome plant immunity and promote disease.
Ustilago maydis, a biotrophic fungal pathogen that infects maize plants, produces
effectors that target hubs in the immune network of the host cell. Here we assess
the capability of U. maydis effector candidates to interact with each other, which
may play a crucial role during the infection process. Using a systematic yeast-two-hybrid
approach and based on a preliminary pooled screen, we selected 63 putative effectors
for one-on-one matings with a library of nearly 300 effector candidates. We found
that 126 of these effector candidates interacted either with themselves or other
predicted effectors. Although the functional relevance of the observed interactions
remains elusive, we propose that the observed abundance in complex formation between
effectors adds an additional level of complexity to effector research and should
be taken into consideration when studying effector evolution and function. Based
on this fundamental finding, we suggest various scenarios which could evolutionarily
drive the formation and stabilization of an effector interactome.

text: Clathrin-mediated endocytosis (CME) is a highly conserved and essential cellular
process in eukaryotic cells, but its dynamic and vital nature makes it challenging
to study using classical genetics tools. In contrast, although small molecules
can acutely and reversibly perturb CME, the few chemical CME inhibitors that have
been applied to plants are either ineffective or show undesirable side effects.
Here, we identify the previously described endosidin9 (ES9) as an inhibitor of
clathrin heavy chain (CHC) function in both Arabidopsis and human cells through
affinity-based target isolation, in vitro binding studies and X-ray crystallography.
Moreover, we present a chemically improved ES9 analog, ES9-17, which lacks the
undesirable side effects of ES9 while retaining the ability to target CHC. ES9
and ES9-17 have expanded the chemical toolbox used to probe CHC function, and
present chemical scaffolds for further design of more specific and potent CHC
inhibitors across different systems.

text: "The development and growth of Arabidopsis thaliana is regulated by a combination
of genetic programing and also by the environmental influences. An important role
in these processes play the phytohormones and among them, auxin is crucial as
it controls many important functions. It is transported through the whole plant
body by creating local and temporal concentration maxima and minima, which have
an impact on the cell status, tissue and organ identity. Auxin has the property
to undergo a directional and finely regulated cell-to-cell transport, which is
enabled by the transport proteins, localized on the plasma membrane. An important
role in this process have the PIN auxin efflux proteins, which have an asymmetric/polar
subcellular localization and determine the directionality of the auxin transport.
During the last years, there were significant advances in understanding how the
trafficking molecular machineries function, including studies on molecular interactions,
function, subcellular localization and intracellular distribution. However, there
is still a lack of detailed characterization on the steps of endocytosis, exocytosis,
endocytic recycling and degradation. Due to this fact, I focused on the identification
of novel trafficking factors and better characterization of the intracellular
trafficking pathways. My PhD thesis consists of an introductory chapter, three
experimental chapters, a chapter containing general discussion, conclusions and
perspectives and also an appendix chapter with published collaborative papers.\r\nThe
first chapter is separated in two different parts: I start by a general introduction
to auxin biology and then I introduce the trafficking pathways in the model plant
Arabidopsis thaliana. Then, I explain also the phosphorylation-signals for polar
targeting and also the roles of the phytohormone strigolactone.\r\nThe second
chapter includes the characterization of bar1/sacsin mutant, which was identified
in a forward genetic screen for novel trafficking components in Arabidopsis thaliana,
where by the implementation of an EMS-treated pPIN1::PIN1-GFP marker line and
by using the established inhibitor of ARF-GEFs, Brefeldin A (BFA) as a tool to
study trafficking processes, we identified a novel factor, which is mediating
the adaptation of the plant cell to ARF-GEF inhibition. The mutation is in a previously
uncharacterized gene, encoding a very big protein that we, based on its homologies,
called SACSIN with domains suggesting roles as a molecular chaperon or as a component
of the ubiquitin-proteasome system. Our physiology and imaging studies revealed
that SACSIN is a crucial plant cell component of the adaptation to the ARF-GEF
inhibition.\r\nThe third chapter includes six subchapters, where I focus on the
role of the phytohormone strigolactone, which interferes with auxin feedback on
PIN internalization. Strigolactone moderates the polar auxin transport by increasing
the internalization of the PIN auxin efflux carriers, which reduces the canalization
related growth responses. In addition, I also studied the role of phosphorylation
in the strigolactone regulation of auxin feedback on PIN internalization. In this
chapter I also present my results on the MAX2-dependence of strigolactone-mediated
root growth inhibition and I also share my results on the auxin metabolomics profiling
after application of GR24.\r\nIn the fourth chapter I studied the effect of two
small molecules ES-9 and ES9-17, which were identified from a collection of small
molecules with the property to impair the clathrin-mediated endocytosis.\r\nIn
the fifth chapter, I discuss all my observations and experimental findings and
suggest alternative hypothesis to interpret my results.\r\nIn the appendix there
are three collaborative published projects. In the first, I participated in the
characterization of the role of ES9 as a small molecule, which is inhibitor of
clathrin- mediated endocytosis in different model organisms. In the second paper,
I contributed to the characterization of another small molecule ES9-17, which
is a non-protonophoric analog of ES9 and also impairs the clathrin-mediated endocytosis
not only in plant cells, but also in mammalian HeLa cells. Last but not least,
I also attach another paper, where I tried to establish the grafting method as
a technique in our lab to study canalization related processes."

text: Plasmodesmata (PD) are plant-specific membrane-lined channels that create
cytoplasmic and membrane continuities between adjacent cells, thereby facilitating
cell–cell communication and virus movement. Plant cells have evolved diverse mechanisms
to regulate PD plasticity in response to numerous environmental stimuli. In particular,
during defense against plant pathogens, the defense hormone, salicylic acid (SA),
plays a crucial role in the regulation of PD permeability in a callose-dependent
manner. Here, we uncover a mechanism by which plants restrict the spreading of
virus and PD cargoes using SA signaling by increasing lipid order and closure
of PD. We showed that exogenous SA application triggered the compartmentalization
of lipid raft nanodomains through a modulation of the lipid raft-regulatory protein,
Remorin (REM). Genetic studies, superresolution imaging, and transmission electron
microscopy observation together demonstrated that Arabidopsis REM1.2 and REM1.3
are crucial for plasma membrane nanodomain assembly to control PD aperture and
functionality. In addition, we also found that a 14-3-3 epsilon protein modulates
REM clustering and membrane nanodomain compartmentalization through its direct
interaction with REM proteins. This study unveils a molecular mechanism by which
the key plant defense hormone, SA, triggers membrane lipid nanodomain reorganization,
thereby regulating PD closure to impede virus spreading.
