text: "During bacterial cell division, the tubulin-homolog FtsZ forms a ring-like
structure at the center of the cell. This so-called Z-ring acts as a scaffold
recruiting several division-related proteins to mid-cell and plays a key role
in distributing proteins at the division site, a feature driven by the treadmilling
motion of FtsZ filaments around the septum. What regulates the architecture, dynamics
and stability of the Z-ring is still poorly understood, but FtsZ-associated proteins
(Zaps) are known to play an important role. \r\nAdvances in fluorescence microscopy
and in vitro reconstitution experiments have helped to shed light into some of
the dynamic properties of these complex systems, but methods that allow to collect
and analyze large quantitative data sets of the underlying polymer dynamics are
still missing.\r\nHere, using an in vitro reconstitution approach, we studied
how different Zaps affect FtsZ filament dynamics and organization into large-scale
patterns, giving special emphasis to the role of the well-conserved protein ZapA.
For this purpose, we use high-resolution fluorescence microscopy combined with
novel image analysis workfows to study pattern organization and polymerization
dynamics of active filaments. We quantified the influence of Zaps on FtsZ on three
diferent spatial scales: the large-scale organization of the membrane-bound filament
network, the underlying\r\npolymerization dynamics and the behavior of single
molecules.\r\nWe found that ZapA cooperatively increases the spatial order of
the filament network, binds only transiently to FtsZ filaments and has no effect
on filament length and treadmilling velocity. Our data provides a model for how
FtsZ-associated proteins can increase the precision and stability of the bacterial
cell division machinery in a\r\nswitch-like manner, without compromising filament
dynamics. Furthermore, we believe that our automated quantitative methods can
be used to analyze a large variety of dynamic cytoskeletal systems, using standard
time-lapse\r\nmovies of homogeneously labeled proteins obtained from experiments
in vitro or even inside the living cell.\r\n"

text: Cryo-electron microscopy (cryo-EM) of cellular specimens provides insights
into biological processes and structures within a native context. However, a major
challenge still lies in the efficient and reproducible preparation of adherent
cells for subsequent cryo-EM analysis. This is due to the sensitivity of many
cellular specimens to the varying seeding and culturing conditions required for
EM experiments, the often limited amount of cellular material and also the fragility
of EM grids and their substrate. Here, we present low-cost and reusable 3D printed
grid holders, designed to improve specimen preparation when culturing challenging
cellular samples directly on grids. The described grid holders increase cell culture
reproducibility and throughput, and reduce the resources required for cell culturing.
We show that grid holders can be integrated into various cryo-EM workflows, including
micro-patterning approaches to control cell seeding on grids, and for generating
samples for cryo-focused ion beam milling and cryo-electron tomography experiments.
Their adaptable design allows for the generation of specialized grid holders customized
to a large variety of applications.

text: The plant hormone auxin plays indispensable roles in plant growth and development.
An essential level of regulation in auxin action is the directional auxin transport
within cells. The establishment of auxin gradient in plant tissue has been attributed
to local auxin biosynthesis and directional intercellular auxin transport, which
both are controlled by various environmental and developmental signals. It is
well established that asymmetric auxin distribution in cells is achieved by polarly
localized PIN-FORMED (PIN) auxin efflux transporters. Despite the initial insights
into cellular mechanisms of PIN polarization obtained from the last decades, the
molecular mechanism and specific regulators mediating PIN polarization remains
elusive. In this thesis, we aim to find novel players in PIN subcellular polarity
regulation during Arabidopsis development. We first characterize the physiological
effect of piperonylic acid (PA) on Arabidopsis hypocotyl gravitropic bending and
PIN polarization. Secondly, we reveal the importance of SCFTIR1/AFB auxin signaling
pathway in shoot gravitropism bending termination. In addition, we also explore
the role of myosin XI complex, and actin cytoskeleton in auxin feedback regulation
on PIN polarity. In Chapter 1, we give an overview of the current knowledge about
PIN-mediated auxin fluxes in various plant tropic responses. In Chapter 2, we
study the physiological effect of PA on shoot gravitropic bending. Our results
show that PA treatment inhibits auxin-mediated PIN3 repolarization by interfering
with PINOID and PIN3 phosphorylation status, ultimately leading to hyperbending
hypocotyls. In Chapter 3, we provide evidence to show that the SCFTIR1/AFB nuclear
auxin signaling pathway is crucial and required for auxin-mediated PIN3 repolarization
and shoot gravitropic bending termination. In Chapter 4, we perform a phosphoproteomics
approach and identify the motor protein Myosin XI and its binding protein, the
MadB2 family, as an essential regulator of PIN polarity for auxin-canalization
related developmental processes. In Chapter 5, we demonstrate the vital role of
actin cytoskeleton in auxin feedback on PIN polarity by regulating PIN subcellular
trafficking. Overall, the data presented in this PhD thesis brings novel insights
into the PIN polar localization regulation that resulted in the (re)establishment
of the polar auxin flow and gradient in response to environmental stimuli during
plant development.

text: "The development of the human brain occurs through a tightly regulated series
of dynamic and adaptive processes during prenatal and postnatal life. A disruption
of this strictly orchestrated series of events can lead to a number of neurodevelopmental
conditions, including Autism Spectrum Disorders (ASDs). ASDs are a very common,
etiologically and phenotypically heterogeneous group of disorders sharing the
core symptoms of social interaction and communication deficits and restrictive
and repetitive interests and behaviors. They are estimated to affect one in 59
individuals in the U.S. and, over the last three decades, mutations in more than
a hundred genetic loci have been convincingly linked to ASD pathogenesis. Yet,
for the vast majority of these ASD-risk genes their role during brain development
and precise molecular function still remain elusive.\r\nDe novo loss of function
mutations in the ubiquitin ligase-encoding gene Cullin 3 (CUL3) lead to ASD. In
the study described here, we used Cul3 mouse models to evaluate the consequences
of Cul3 mutations in vivo. Our results show that Cul3 heterozygous knockout mice
exhibit deficits in motor coordination as well as ASD-relevant social and cognitive
impairments. Cul3+/-, Cul3+/fl Emx1-Cre and Cul3fl/fl Emx1-Cre mutant brains display
cortical lamination abnormalities due to defective migration of post-mitotic excitatory
neurons, as well as reduced numbers of excitatory and inhibitory neurons. In line
with the observed abnormal cortical organization, Cul3 heterozygous deletion is
associated with decreased spontaneous excitatory and inhibitory activity in the
cortex. At the molecular level we show that Cul3 regulates cytoskeletal and adhesion
protein abundance in the mouse embryonic cortex. Abnormal regulation of cytoskeletal
proteins in Cul3 mutant neural cells results in atypical organization of the actin
mesh at the cell leading edge. Of note, heterozygous deletion of Cul3 in adult
mice does not induce the majority of the behavioral defects observed in constitutive
Cul3 haploinsufficient animals, pointing to a critical time-window for Cul3 deficiency.\r\nIn
conclusion, our data indicate that Cul3 plays a critical role in the regulation
of cytoskeletal proteins and neuronal migration. ASD-associated defects and behavioral
abnormalities are primarily due to dosage sensitive Cul3 functions at early brain
developmental stages."

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.

text: Global tissue tension anisotropy has been shown to trigger stereotypical cell
division orientation by elongating mitotic cells along the main tension axis.
Yet, how tissue tension elongates mitotic cells despite those cells undergoing
mitotic rounding (MR) by globally upregulating cortical actomyosin tension remains
unclear. We addressed this question by taking advantage of ascidian embryos, consisting
of a small number of interphasic and mitotic blastomeres and displaying an invariant
division pattern. We found that blastomeres undergo MR by locally relaxing cortical
tension at their apex, thereby allowing extrinsic pulling forces from neighboring
interphasic blastomeres to polarize their shape and thus division orientation.
Consistently, interfering with extrinsic forces by reducing the contractility
of interphasic blastomeres or disrupting the establishment of asynchronous mitotic
domains leads to aberrant mitotic cell division orientations. Thus, apical relaxation
during MR constitutes a key mechanism by which tissue tension anisotropy controls
stereotypical cell division orientation.

text: The actin-related protein (Arp)2/3 complex nucleates branched actin filament
networks pivotal for cell migration, endocytosis and pathogen infection. Its activation
is tightly regulated and involves complex structural rearrangements and actin
filament binding, which are yet to be understood. Here, we report a 9.0 Å resolution
structure of the actin filament Arp2/3 complex branch junction in cells using
cryo-electron tomography and subtomogram averaging. This allows us to generate
an accurate model of the active Arp2/3 complex in the branch junction and its
interaction with actin filaments. Notably, our model reveals a previously undescribed
set of interactions of the Arp2/3 complex with the mother filament, significantly
different to the previous branch junction model. Our structure also indicates
a central role for the ArpC3 subunit in stabilizing the active conformation.

text: "Mosaic analysis with double markers (MADM) technology enables concomitant
fluorescent cell labeling and induction of uniparental chromosome disomy (UPD)
with single-cell resolution. In UPD, imprinted genes are either overexpressed
2-fold or are not expressed. Here, the MADM platform is utilized to probe imprinting
phenotypes at the transcriptional level. This protocol highlights major steps
for the generation and isolation of projection neurons and astrocytes with MADM-induced
UPD from mouse cerebral cortex for downstream single-cell and low-input sample
RNA-sequencing experiments.\r\n\r\nFor complete details on the use and execution

text: Metabolic adaptation is a critical feature of migrating cells. It tunes the
metabolic programs of migrating cells to allow them to efficiently exert their
crucial roles in development, inflammatory responses and tumor metastasis. Cell
migration through physically challenging contexts requires energy. However, how
the metabolic reprogramming that underlies in vivo cell invasion is controlled
is still unanswered. In my PhD project, I identify a novel conserved metabolic
shift in Drosophila melanogaster immune cells that by modulating their bioenergetic
potential controls developmentally programmed tissue invasion. We show that this
regulation requires a novel conserved nuclear protein, named Atossa. Atossa enhances
the transcription of a set of proteins, including an RNA helicase Porthos and
two metabolic enzymes, each of which increases the tissue invasion of leading
Drosophila macrophages and can rescue the atossa mutant phenotype. Porthos selectively
regulates the translational efficiency of a subset of mRNAs containing a 5’-UTR
cis-regulatory TOP-like sequence. These 5’TOPL mRNA targets encode mitochondrial-related
proteins, including subunits of mitochondrial oxidative phosphorylation (OXPHOS)
components III and V and other metabolic-related proteins. Porthos powers up mitochondrial
OXPHOS to engender a sufficient ATP supply, which is required for tissue invasion
of leading macrophages. Atossa’s two vertebrate orthologs rescue the invasion
defect. In my PhD project, I elucidate that Atossa displays a conserved developmental
metabolic control to modulate metabolic capacities and the cellular energy state,
through altered transcription and translation, to aid the tissue infiltration
of leading cells into energy demanding barriers.

text: Plants, like other multicellular organisms, survive through a delicate balance
between growth and defense against pathogens. Salicylic acid (SA) is a major defense
signal in plants, and the perception mechanism as well as downstream signaling
activating the immune response are known. Here, we identify a parallel SA signaling
that mediates growth attenuation. SA directly binds to A subunits of protein phosphatase
2A (PP2A), inhibiting activity of this complex. Among PP2A targets, the PIN2 auxin
transporter is hyperphosphorylated in response to SA, leading to changed activity
of this important growth regulator. Accordingly, auxin transport and auxin-mediated
root development, including growth, gravitropic response, and lateral root organogenesis,
are inhibited. This study reveals how SA, besides activating immunity, concomitantly
attenuates growth through crosstalk with the auxin distribution network. Further
analysis of this dual role of SA and characterization of additional SA-regulated
PP2A targets will provide further insights into mechanisms maintaining a balance
between growth and defense.

text: In plants, clathrin mediated endocytosis (CME) represents the major route
for cargo internalisation from the cell surface. It has been assumed to operate
in an evolutionary conserved manner as in yeast and animals. Here we report characterisation
of ultrastructure, dynamics and mechanisms of plant CME as allowed by our advancement
in electron microscopy and quantitative live imaging techniques. Arabidopsis CME
appears to follow the constant curvature model and the bona fide CME population
generates vesicles of a predominantly hexagonal-basket type; larger and with faster
kinetics than in other models. Contrary to the existing paradigm, actin is dispensable
for CME events at the plasma membrane but plays a unique role in collecting endocytic
vesicles, sorting of internalised cargos and directional endosome movement that
itself actively promote CME events. Internalized vesicles display a strongly delayed
and sequential uncoating. These unique features highlight the independent evolution
of the plant CME mechanism during the autonomous rise of multicellularity in eukaryotes.

text: The eukaryotic endomembrane system is controlled by small GTPases of the Rab
family, which are activated at defined times and locations in a switch-like manner.
While this switch is well understood for an individual protein, how regulatory
networks produce intracellular activity patterns is currently not known. Here,
we combine in vitro reconstitution experiments with computational modeling to
study a minimal Rab5 activation network. We find that the molecular interactions
in this system give rise to a positive feedback and bistable collective switching
of Rab5. Furthermore, we find that switching near the critical point is intrinsically
stochastic and provide evidence that controlling the inactive population of Rab5
on the membrane can shape the network response. Notably, we demonstrate that collective
switching can spread on the membrane surface as a traveling wave of Rab5 activation.
Together, our findings reveal how biochemical signaling networks control vesicle
trafficking pathways and how their nonequilibrium properties define the spatiotemporal
organization of the cell.

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.

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: Plants as non-mobile organisms constantly integrate varying environmental
signals to flexibly adapt their growth and development. Local fluctuations in
water and nutrient availability, sudden changes in temperature or other abiotic
and biotic stresses can trigger changes in the growth of plant organs. Multiple
mutually interconnected hormonal signaling cascades act as essential endogenous
translators of these exogenous signals in the adaptive responses of plants. Although
the molecular backbones of hormone transduction pathways have been identified,
the mechanisms underlying their interactions are largely unknown. Here, using
genome wide transcriptome profiling we identify an auxin and cytokinin cross-talk
component; SYNERGISTIC ON AUXIN AND CYTOKININ 1 (SYAC1), whose expression in roots
is strictly dependent on both of these hormonal pathways. We show that SYAC1 is
a regulator of secretory pathway, whose enhanced activity interferes with deposition
of cell wall components and can fine-tune organ growth and sensitivity to soil
pathogens.

text: 'Scientific research is to date largely restricted to wealthy laboratories
in developed nations due to the necessity of complex and expensive equipment.
This inequality limits the capacity of science to be used as a diplomatic channel.
Maker movements use open-source technologies including additive manufacturing
(3D printing) and laser cutting, together with low-cost computers for developing
novel products. This movement is setting the groundwork for a revolution, allowing
scientific equipment to be sourced at a fraction of the cost and has the potential
to increase the availability of equipment for scientists around the world. Science
education is increasingly recognized as another channel for science diplomacy.
In this perspective, we introduce the idea that the Maker movement and open-source
technologies have the potential to revolutionize science, technology, engineering
and mathematics (STEM) education worldwide. We present an open-source STEM didactic
tool called SCOPES (Sparking Curiosity through Open-source Platforms in Education
and Science). SCOPES is self-contained, independent of local resources, and cost-effective.
SCOPES can be adapted to communicate complex subjects from genetics to neurobiology,
perform real-world biological experiments and explore digitized scientific samples.
We envision such platforms will enhance science diplomacy by providing a means
for scientists to share their findings with classrooms and for educators to incorporate
didactic concepts into STEM lessons. By providing students the opportunity to
design, perform, and share scientific experiments, students also experience firsthand
the benefits of a multinational scientific community. We provide instructions
on how to build and use SCOPES on our webpage: http://scopeseducation.org.'

text: Beginning from a limited pool of progenitors, the mammalian cerebral cortex
forms highly organized functional neural circuits. However, the underlying cellular
and molecular mechanisms regulating lineage transitions of neural stem cells (NSCs)
and eventual production of neurons and glia in the developing neuroepithelium
remains unclear. Methods to trace NSC division patterns and map the lineage of
clonally related cells have advanced dramatically. However, many contemporary
lineage tracing techniques suffer from the lack of cellular resolution of progeny
cell fate, which is essential for deciphering progenitor cell division patterns.
Presented is a protocol using mosaic analysis with double markers (MADM) to perform
in vivo clonal analysis. MADM concomitantly manipulates individual progenitor
cells and visualizes precise division patterns and lineage progression at unprecedented
single cell resolution. MADM-based interchromosomal recombination events during
the G2-X phase of mitosis, together with temporally inducible CreERT2, provide
exact information on the birth dates of clones and their division patterns. Thus,
MADM lineage tracing provides unprecedented qualitative and quantitative optical
readouts of the proliferation mode of stem cell progenitors at the single cell
level. MADM also allows for examination of the mechanisms and functional requirements
of candidate genes in NSC lineage progression. This method is unique in that comparative
analysis of control and mutant subclones can be performed in the same tissue environment
in vivo. Here, the protocol is described in detail, and experimental paradigms
to employ MADM for clonal analysis and lineage tracing in the developing cerebral
cortex are demonstrated. Importantly, this protocol can be adapted to perform
MADM clonal analysis in any murine stem cell niche, as long as the CreERT2 driver
is present.

text: 'Cells navigating through complex tissues face a fundamental challenge: while
multiple protrusions explore different paths, the cell needs to avoid entanglement.
How a cell surveys and then corrects its own shape is poorly understood. Here,
we demonstrate that spatially distinct microtubule dynamics regulate amoeboid
cell migration by locally promoting the retraction of protrusions. In migrating
dendritic cells, local microtubule depolymerization within protrusions remote
from the microtubule organizing center triggers actomyosin contractility controlled
by RhoA and its exchange factor Lfc. Depletion of Lfc leads to aberrant myosin
localization, thereby causing two effects that rate-limit locomotion: (1) impaired
cell edge coordination during path finding and (2) defective adhesion resolution.
Compromised shape control is particularly hindering in geometrically complex microenvironments,
where it leads to entanglement and ultimately fragmentation of the cell body.
We thus demonstrate that microtubules can act as a proprioceptive device: they
sense cell shape and control actomyosin retraction to sustain cellular coherence.'

text: Eukaryotic cells migrate by coupling the intracellular force of the actin
cytoskeleton to the environment. While force coupling is usually mediated by transmembrane
adhesion receptors, especially those of the integrin family, amoeboid cells such
as leukocytes can migrate extremely fast despite very low adhesive forces1. Here
we show that leukocytes cannot only migrate under low adhesion but can also transmit
forces in the complete absence of transmembrane force coupling. When confined
within three-dimensional environments, they use the topographical features of
the substrate to propel themselves. Here the retrograde flow of the actin cytoskeleton
follows the texture of the substrate, creating retrograde shear forces that are
sufficient to drive the cell body forwards. Notably, adhesion-dependent and adhesion-independent
migration are not mutually exclusive, but rather are variants of the same principle
of coupling retrograde actin flow to the environment and thus can potentially
operate interchangeably and simultaneously. As adhesion-free migration is independent
of the chemical composition of the environment, it renders cells completely autonomous
in their locomotive behaviour.
