text: Tropisms are among the most important growth responses for plant adaptation
to the surrounding environment. One of the most common tropisms is root gravitropism.
Root gravitropism enables the plant to anchor securely to the soil enabling the
absorption of water and nutrients. Most of the knowledge related to the plant
gravitropism has been acquired from the flowering plants, due to limited research
in non-seed plants. Limited research on non-seed plants is due in large part to
the lack of standard research methods. Here, we describe the experimental methods
to evaluate gravitropism in representative non-seed plant species, including the
non-vascular plant moss Physcomitrium patens, the early diverging extant vascular
plant lycophyte Selaginella moellendorffii and fern Ceratopteris richardii. In
addition, we introduce the methods used for statistical analysis of the root gravitropism
in non-seed plant species.

Ann Banks at Purdue University. This work was supported by funding from the European

text: The analysis of dynamic cellular processes such as plant cytokinesis stands
and falls with live-cell time-lapse confocal imaging. Conventional approaches
to time-lapse imaging of cell division in Arabidopsis root tips are tedious and
have low throughput. Here, we describe a protocol for long-term time-lapse simultaneous
imaging of multiple root tips on a vertical-stage confocal microscope with automated
root tracking. We also provide modifications of the basic protocol to implement
this imaging method in the analysis of genetic, pharmacological or laser ablation
wounding-mediated experimental manipulations. Our method dramatically improves
the efficiency of cell division time-lapse imaging by increasing the throughput,
while reducing the person-hour requirements of such experiments.

text: Plants develop new organs to adjust their bodies to dynamic changes in the
environment. How independent organs achieve anisotropic shapes and polarities
is poorly understood. To address this question, we constructed a mechano-biochemical
model for Arabidopsis root meristem growth that integrates biologically plausible
principles. Computer model simulations demonstrate how differential growth of
neighboring tissues results in the initial symmetry-breaking leading to anisotropic
root growth. Furthermore, the root growth feeds back on a polar transport network
of the growth regulator auxin. Model, predictions are in close agreement with
in vivo patterns of anisotropic growth, auxin distribution, and cell polarity,
as well as several root phenotypes caused by chemical, mechanical, or genetic
perturbations. Our study demonstrates that the combination of tissue mechanics
and polar auxin transport organizes anisotropic root growth and cell polarities
during organ outgrowth. Therefore, a mobile auxin signal transported through immobile
cells drives polarity and growth mechanics to coordinate complex organ development.

text: 'Machines enabled the Industrial Revolution and are central to modern technological
progress: A machine’s parts transmit forces, motion, and energy to one another
in a predetermined manner. Today’s engineering frontier, building artificial micromachines
that emulate the biological machinery of living organisms, requires faithful assembly
and energy consumption at the microscale. Here, we demonstrate the programmable
assembly of active particles into autonomous metamachines using optical templates.
Metamachines, or machines made of machines, are stable, mobile and autonomous
architectures, whose dynamics stems from the geometry. We use the interplay between
anisotropic force generation of the active colloids with the control of their
orientation by local geometry. This allows autonomous reprogramming of active
particles of the metamachines to achieve multiple functions. It permits the modular
assembly of metamachines by fusion, reconfiguration of metamachines and, we anticipate,
a shift in focus of self-assembly towards active matter and reprogrammable materials.'

text: Mutations affecting mTOR or RAS signaling underlie defined syndromes (the
so-called mTORopathies and RASopathies) with high risk for Autism Spectrum Disorder
(ASD). These syndromes show a broad variety of somatic phenotypes including cancers,
skin abnormalities, heart disease and facial dysmorphisms. Less well studied are
the neuropsychiatric symptoms such as ASD. Here, we assess the relevance of these
signalopathies in ASD reviewing genetic, human cell model, rodent studies and
clinical trials. We conclude that signalopathies have an increased liability for
ASD and that, in particular, ASD individuals with dysmorphic features and intellectual
disability (ID) have a higher chance for disruptive mutations in RAS- and mTOR-related
genes. Studies on rodent and human cell models confirm aberrant neuronal development
as the underlying pathology. Human studies further suggest that multiple hits
are necessary to induce the respective phenotypes. Recent clinical trials do only
report improvements for comorbid conditions such as epilepsy or cancer but not
for behavioral aspects. Animal models show that treatment during early development
can rescue behavioral phenotypes. Taken together, we suggest investigating the
differential roles of mTOR and RAS signaling in both human and rodent models,
and to test drug treatment both during and after neuronal development in the available
model systems

text: Advanced transcriptome sequencing has revealed that the majority of eukaryotic
genes undergo alternative splicing (AS). Nonetheless, little effort has been dedicated
to investigating the functional relevance of particular splicing events, even
those in the key developmental and hormonal regulators. Combining approaches of
genetics, biochemistry and advanced confocal microscopy, we describe the impact
of alternative splicing on the PIN7 gene in the model plant Arabidopsis thaliana.
PIN7 encodes a polarly localized transporter for the phytohormone auxin and produces
two evolutionarily conserved transcripts, PIN7a and PIN7b. PIN7a and PIN7b, differing
in a four amino acid stretch, exhibit almost identical expression patterns and
subcellular localization. We reveal that they are closely associated and mutually
influence each other's mobility within the plasma membrane. Phenotypic complementation
tests indicate that the functional contribution of PIN7b per se is minor, but
it markedly reduces the prominent PIN7a activity, which is required for correct
seedling apical hook formation and auxin-mediated tropic responses. Our results
establish alternative splicing of the PIN family as a conserved, functionally
relevant mechanism, revealing an additional regulatory level of auxin-mediated
plant development.

text: 'During the past decade, the scientific community and outside observers have
noted a concerning lack of rigor and transparency in preclinical research that
led to talk of a “reproducibility crisis” in the life sciences (Baker, 2016; Bespalov
& Steckler, 2018; Heddleston et al, 2021). Various measures have been proposed
to address the problem: from better training of scientists to more oversight to
expanded publishing practices such as preregistration of studies. The recently
published EQIPD (Enhancing Quality in Preclinical Data) System is, to date, the
largest initiative that aims to establish a systematic approach for increasing
the robustness and reliability of biomedical research (Bespalov et al, 2021).
However, promoting a cultural change in research practices warrants a broad adoption
of the Quality System and its underlying philosophy. It is here that academic
Core Facilities (CF), research service providers at universities and research
institutions, can make a difference. It is fair to assume that a significant fraction
of published data originated from experiments that were designed, run, or analyzed
in CFs. These academic services play an important role in the research ecosystem
by offering access to cutting-edge equipment and by developing and testing novel
techniques and methods that impact research in the academic and private sectors
alike (Bikovski et al, 2020). Equipment and infrastructure are not the only value:
CFs employ competent personnel with profound knowledge and practical experience
of the specific field of interest: animal behavior, imaging, crystallography,
genomics, and so on. Thus, CFs are optimally positioned to address concerns about
the quality and robustness of preclinical research.'

text: We study the overlaps between right and left eigenvectors for random matrices
of the spherical ensemble, as well as truncated unitary ensembles in the regime
where half of the matrix at least is truncated. These two integrable models exhibit
a form of duality, and the essential steps of our investigation can therefore
be performed in parallel. In every case, conditionally on all eigenvalues, diagonal
overlaps are shown to be distributed as a product of independent random variables
with explicit distributions. This enables us to prove that the scaled diagonal
overlaps, conditionally on one eigenvalue, converge in distribution to a heavy-tail
limit, namely, the inverse of a γ2 distribution. We also provide formulae for
the conditional expectation of diagonal and off-diagonal overlaps, either with
respect to one eigenvalue, or with respect to the whole spectrum. These results,
analogous to what is known for the complex Ginibre ensemble, can be obtained in
these cases thanks to integration techniques inspired from a previous work by
Forrester & Krishnapur.

text: A precise quantitative description of the ultrastructural characteristics
underlying biological mechanisms is often key to their understanding. This is
particularly true for dynamic extra- and intracellular filamentous assemblies,
playing a role in cell motility, cell integrity, cytokinesis, tissue formation
and maintenance. For example, genetic manipulation or modulation of actin regulatory
proteins frequently manifests in changes of the morphology, dynamics, and ultrastructural
architecture of actin filament-rich cell peripheral structures, such as lamellipodia
or filopodia. However, the observed ultrastructural effects often remain subtle
and require sufficiently large datasets for appropriate quantitative analysis.
The acquisition of such large datasets has been enabled by recent advances in
high-throughput cryo-electron tomography (cryo-ET) methods. This also necessitates
the development of complementary approaches to maximize the extraction of relevant
biological information. We have developed a computational toolbox for the semi-automatic
quantification of segmented and vectorized filamentous networks from pre-processed
cryo-electron tomograms, facilitating the analysis and cross-comparison of multiple
experimental conditions. GUI-based components simplify the processing of data
and allow users to obtain a large number of ultrastructural parameters describing
filamentous assemblies. We demonstrate the feasibility of this workflow by analyzing
cryo-ET data of untreated and chemically perturbed branched actin filament networks
and that of parallel actin filament arrays. In principle, the computational toolbox
presented here is applicable for data analysis comprising any type of filaments
in regular (i.e. parallel) or random arrangement. We show that it can ease the
identification of key differences between experimental groups and facilitate the
in-depth analysis of ultrastructural data in a time-efficient manner.

text: "Indirect reciprocity in evolutionary game theory is a prominent mechanism
for explaining the evolution of cooperation among unrelated individuals. In contrast
to direct reciprocity, which is based on individuals meeting repeatedly, and conditionally
cooperating by using their own experiences, indirect reciprocity is based on individuals’
reputations. If a player helps another, this increases the helper’s public standing,
benefitting them in the future. This lets cooperation in the population emerge
without individuals having to meet more than once. While the two modes of reciprocity
are intertwined, they are difficult to compare. Thus, they are usually studied
in isolation. Direct reciprocity can maintain cooperation with simple strategies,
and is robust against noise even when players do not remember more\r\nthan their
partner’s last action. Meanwhile, indirect reciprocity requires its successful
strategies, or social norms, to be more complex. Exhaustive search previously
identified eight such norms, called the “leading eight”, which excel at maintaining
cooperation. However, as the first result of this thesis, we show that the leading
eight break down once we remove the fundamental assumption that information is
synchronized and public, such that everyone agrees on reputations. Once we consider
a more realistic scenario of imperfect information, where reputations are private,
and individuals occasionally misinterpret or miss observations, the leading eight
do not promote cooperation anymore. Instead, minor initial disagreements can proliferate,
fragmenting populations into subgroups. In a next step, we consider ways to mitigate
this issue. We first explore whether introducing “generosity” can stabilize cooperation
when players use the leading eight strategies in noisy environments. This approach
of modifying strategies to include probabilistic elements for coping with errors
is known to work well in direct reciprocity. However, as we show here, it fails
for the more complex norms of indirect reciprocity. Imperfect information still
prevents cooperation from evolving. On the other hand, we succeeded to show in
this thesis that modifying the leading eight to use “quantitative assessment”,
i.e. tracking reputation scores on a scale beyond good and bad, and making overall
judgments of others based on a threshold, is highly successful, even when noise
increases in the environment. Cooperation can flourish when reputations\r\nare
more nuanced, and players have a broader understanding what it means to be “good.”
Finally, we present a single theoretical framework that unites the two modes of
reciprocity despite their differences. Within this framework, we identify a novel
simple and successful strategy for indirect reciprocity, which can cope with noisy
environments and has an analogue in direct reciprocity. We can also analyze decision
making when different sources of information are available. Our results help highlight
that for sustaining cooperation, already the most simple rules of reciprocity
can be sufficient."

text: Turbulence generally arises in shear flows if velocities and hence, inertial
forces are sufficiently large. In striking contrast, viscoelastic fluids can exhibit
disordered motion even at vanishing inertia. Intermediate between these cases,
a state of chaotic motion, “elastoinertial turbulence” (EIT), has been observed
in a narrow Reynolds number interval. We here determine the origin of EIT in experiments
and show that characteristic EIT structures can be detected across an unexpectedly
wide range of parameters. Close to onset, a pattern of chevron-shaped streaks
emerges in qualitative agreement with linear and weakly nonlinear theory. However,
in experiments, the dynamics remain weakly chaotic, and the instability can be
traced to far lower Reynolds numbers than permitted by theory. For increasing
inertia, the flow undergoes a transformation to a wall mode composed of inclined
near-wall streaks and shear layers. This mode persists to what is known as the
“maximum drag reduction limit,” and overall EIT is found to dominate viscoelastic
flows across more than three orders of magnitude in Reynolds number.

text: De novo protein synthesis is required for synapse modifications underlying
stable memory encoding. Yet neurons are highly compartmentalized cells and how
protein synthesis can be regulated at the synapse level is unknown. Here, we characterize
neuronal signaling complexes formed by the postsynaptic scaffold GIT1, the mechanistic
target of rapamycin (mTOR) kinase, and Raptor that couple synaptic stimuli to
mTOR-dependent protein synthesis; and identify NMDA receptors containing GluN3A
subunits as key negative regulators of GIT1 binding to mTOR. Disruption of GIT1/mTOR
complexes by enhancing GluN3A expression or silencing GIT1 inhibits synaptic mTOR
activation and restricts the mTOR-dependent translation of specific activity-regulated
mRNAs. Conversely, GluN3A removal enables complex formation, potentiates mTOR-dependent
protein synthesis, and facilitates the consolidation of associative and spatial
memories in mice. The memory enhancement becomes evident with light or spaced
training, can be achieved by selectively deleting GluN3A from excitatory neurons
during adulthood, and does not compromise other aspects of cognition such as memory
flexibility or extinction. Our findings provide mechanistic insight into synaptic
translational control and reveal a potentially selective target for cognitive
enhancement.

text: 'Nitrogen is an essential macronutrient determining plant growth, development
and affecting agricultural productivity. Root, as a hub that perceives and integrates
local and systemic signals on the plant’s external and endogenous nitrogen resources,
communicates with other plant organs to consolidate their physiology and development
in accordance with actual nitrogen balance. Over the last years, numerous studies
demonstrated that these comprehensive developmental adaptations rely on the interaction
between pathways controlling nitrogen homeostasis and hormonal networks acting
globally in the plant body. However, molecular insights into how the information
about the nitrogen status is translated through hormonal pathways into specific
developmental output are lacking. In my work, I addressed so far poorly understood
mechanisms underlying root-to-shoot communication that lead to a rapid re-adjustment
of shoot growth and development after nitrate provision. Applying a combination
of molecular, cell, and developmental biology approaches, genetics and grafting
experiments as well as hormonal analytics, I identified and characterized an unknown
molecular framework orchestrating shoot development with a root nitrate sensory
system. '

text: Bacteria-host interactions represent a continuous trade-off between benefit
and risk. Thus, the host immune response is faced with a non-trivial problem –
accommodate beneficial commensals and remove harmful pathogens. This is especially
difficult as molecular patterns, such as lipopolysaccharide or specific surface
organelles such as pili, are conserved in both, commensal and pathogenic bacteria.
Type 1 pili, tightly regulated by phase variation, are considered an important
virulence factor of pathogenic bacteria as they facilitate invasion into host
cells. While invasion represents a de facto passive mechanism for pathogens to
escape the host immune response, we demonstrate a fundamental role of type 1 pili
as active modulators of the innate and adaptive immune response.

text: A high-resolution structure of trimeric cyanobacterial Photosystem I (PSI)
from Thermosynechococcus elongatus was reported as the first atomic model of PSI
almost 20 years ago. However, the monomeric PSI structure has not yet been reported
despite long-standing interest in its structure and extensive spectroscopic characterization
of the loss of red chlorophylls upon monomerization. Here, we describe the structure
of monomeric PSI from Thermosynechococcus elongatus BP-1. Comparison with the
trimer structure gave detailed insights into monomerization-induced changes in
both the central trimerization domain and the peripheral regions of the complex.
Monomerization-induced loss of red chlorophylls is assigned to a cluster of chlorophylls
adjacent to PsaX. Based on our findings, we propose a role of PsaX in the stabilization
of red chlorophylls and that lipids of the surrounding membrane present a major
source of thermal energy for uphill excitation energy transfer from red chlorophylls
to P700.

text: A key attribute of persistent or recurring bacterial infections is the ability
of the pathogen to evade the host’s immune response. Many Enterobacteriaceae express
type 1 pili, a pre-adapted virulence trait, to invade host epithelial cells and
establish persistent infections. However, the molecular mechanisms and strategies
by which bacteria actively circumvent the immune response of the host remain poorly
understood. Here, we identified CD14, the major co-receptor for lipopolysaccharide
detection, on dendritic cells as a previously undescribed binding partner of FimH,
the protein located at the tip of the type 1 pilus of Escherichia coli. The FimH
amino acids involved in CD14 binding are highly conserved across pathogenic and
non-pathogenic strains. Binding of pathogenic bacteria to CD14 lead to reduced
dendritic cell migration and blunted expression of co-stimulatory molecules, both
rate-limiting factors of T cell activation. While defining an active molecular
mechanism of immune evasion by pathogens, the interaction between FimH and CD14
represents a potential target to interfere with persistent and recurrent infections,
such as urinary tract infections or Crohn’s disease.

text: Mosaic analysis with double markers (MADM) technology enables the generation
of genetic mosaic tissue in mice. MADM enables concomitant fluorescent cell labeling
and introduction of a mutation of a gene of interest with single-cell resolution.
This protocol highlights major steps for the generation of genetic mosaic tissue
and the isolation and processing of respective tissues for downstream histological
analysis. For complete details on the use and execution of this protocol, please

text: To survive elevated temperatures, ectotherms adjust the fluidity of membranes
by fine-tuning lipid desaturation levels in a process previously described to
be cell autonomous. We have discovered that, in Caenorhabditis elegans, neuronal
heat shock factor 1 (HSF-1), the conserved master regulator of the heat shock
response (HSR), causes extensive fat remodeling in peripheral tissues. These changes
include a decrease in fat desaturase and acid lipase expression in the intestine
and a global shift in the saturation levels of plasma membrane’s phospholipids.
The observed remodeling of plasma membrane is in line with ectothermic adaptive
responses and gives worms a cumulative advantage to warm temperatures. We have
determined that at least 6 TAX-2/TAX-4 cyclic guanosine monophosphate (cGMP) gated
channel expressing sensory neurons, and transforming growth factor ß (TGF-β)/bone
morphogenetic protein (BMP) are required for signaling across tissues to modulate
fat desaturation. We also find neuronal hsf-1 is not only sufficient but also
partially necessary to control the fat remodeling response and for survival at
warm temperatures. This is the first study to show that a thermostat-based mechanism
can cell nonautonomously coordinate membrane saturation and composition across
tissues in a multicellular animal.

text: Molecular chaperones are central to cellular protein homeostasis. Dynamic
disorder is a key feature of the complexes of molecular chaperones and their client
proteins, and it facilitates the client release towards a folded state or the
handover to downstream components. The dynamic nature also implies that a given
chaperone can interact with many different client proteins, based on physico-chemical
sequence properties rather than on structural complementarity of their (folded)
3D structure. Yet, the balance between this promiscuity and some degree of client
specificity is poorly understood. Here, we review recent atomic-level descriptions
of chaperones with client proteins, including chaperones in complex with intrinsically
disordered proteins, with membrane-protein precursors, or partially folded client
proteins. We focus hereby on chaperone-client interactions that are independent
of ATP. The picture emerging from these studies highlights the importance of dynamics
in these complexes, whereby several interaction types, not only hydrophobic ones,
contribute to the complex formation. We discuss these features of chaperone-client
complexes and possible factors that may contribute to this balance of promiscuity
and specificity.

text: Off-chain protocols (channels) are a promising solution to the scalability
and privacy challenges of blockchain payments. Current proposals, however, require
synchrony assumptions to preserve the safety of a channel, leaking to an adversary
the exact amount of time needed to control the network for a successful attack.
In this paper, we introduce Brick, the first payment channel that remains secure
under network asynchrony and concurrently provides correct incentives. The core
idea is to incorporate the conflict resolution process within the channel by introducing
a rational committee of external parties, called wardens. Hence, if a party wants
to close a channel unilaterally, it can only get the committee’s approval for
the last valid state. Additionally, Brick provides sub-second latency because
it does not employ heavy-weight consensus. Instead, Brick uses consistent broadcast
to announce updates and close the channel, a light-weight abstraction that is
powerful enough to preserve safety and liveness to any rational parties. We formally
define and prove for Brick the properties a payment channel construction should
fulfill. We also design incentives for Brick such that honest and rational behavior
aligns. Finally, we provide a reference implementation of the smart contracts
in Solidity.
