text: 'One hallmark of plant cells is their cell wall. They protect cells against
the environment and high turgor and mediate morphogenesis through the dynamics
of their mechanical and chemical properties. The walls are a complex polysaccharidic
structure. Although their biochemical composition is well known, how the different
components organize in the volume of the cell wall and interact with each other
is not well understood and yet is key to the wall’s mechanical properties. To
investigate the ultrastructure of the plant cell wall, we imaged the walls of
onion (Allium cepa) bulbs in a near-native state via cryo-focused ion beam milling
(cryo-FIB milling) and cryo-electron tomography (cryo-ET). This allowed the high-resolution
visualization of cellulose fibers in situ. We reveal the coexistence of dense
fiber fields bathed in a reticulated matrix we termed “meshing,” which is more
abundant at the inner surface of the cell wall. The fibers adopted a regular bimodal
angular distribution at all depths in the cell wall and bundled according to their
orientation, creating layers within the cell wall. Concomitantly, employing homogalacturonan
(HG)-specific enzymatic digestion, we observed changes in the meshing, suggesting
that it is—at least in part—composed of HG pectins. We propose the following model
for the construction of the abaxial epidermal primary cell wall: the cell deposits
successive layers of cellulose fibers at −45° and +45° relative to the cell’s
long axis and secretes the surrounding HG-rich meshing proximal to the plasma
membrane, which then migrates to more distal regions of the cell wall.'

text: Empirical essays of fitness landscapes suggest that they may be rugged, that
is having multiple fitness peaks. Such fitness landscapes, those that have multiple
peaks, necessarily have special local structures, called reciprocal sign epistasis
(Poelwijk et al. in J Theor Biol 272:141–144, 2011). Here, we investigate the
quantitative relationship between the number of fitness peaks and the number of
reciprocal sign epistatic interactions. Previously, it has been shown (Poelwijk
et al. in J Theor Biol 272:141–144, 2011) that pairwise reciprocal sign epistasis
is a necessary but not sufficient condition for the existence of multiple peaks.
Applying discrete Morse theory, which to our knowledge has never been used in
this context, we extend this result by giving the minimal number of reciprocal
sign epistatic interactions required to create a given number of peaks.

text: "Background: Proper cerebral cortical development depends on the tightly orchestrated
migration of newly born neurons from the inner ventricular and subventricular
zones to the outer cortical plate. Any disturbance in this process during prenatal
stages may lead to neuronal migration disorders (NMDs), which can vary in extent
from focal to global. Furthermore, NMDs show a substantial comorbidity with other
neurodevelopmental disorders, notably autism spectrum disorders (ASDs). Our previous
work demonstrated focal neuronal migration defects in mice carrying loss-of-function
alleles of the recognized autism risk gene WDFY3. However, the cellular origins
of these defects in Wdfy3 mutant mice remain elusive and uncovering it will provide
critical insight into WDFY3-dependent disease pathology.\r\nMethods: Here, in
an effort to untangle the origins of NMDs in Wdfy3lacZ mice, we employed mosaic
analysis with double markers (MADM). MADM technology enabled us to genetically
distinctly track and phenotypically analyze mutant and wild-type cells concomitantly
in vivo using immunofluorescent techniques.\r\nResults: We revealed a cell autonomous
requirement of WDFY3 for accurate laminar positioning of cortical projection neurons
and elimination of mispositioned cells during early postnatal life. In addition,
we identified significant deviations in dendritic arborization, as well as synaptic
density and morphology between wild type, heterozygous, and homozygous Wdfy3 mutant
neurons in Wdfy3-MADM reporter mice at postnatal stages.\r\nLimitations: While
Wdfy3 mutant mice have provided valuable insight into prenatal aspects of ASD
pathology that remain inaccessible to investigation in humans, like most animal
models, they do not a perfectly replicate all aspects of human ASD biology. The
lack of human data makes it indeterminate whether morphological deviations described
here apply to ASD patients or some of the other neurodevelopmental conditions
associated with WDFY3 mutation.\r\nConclusions: Our genetic approach revealed
several cell autonomous requirements of WDFY3 in neuronal development that could
underlie the pathogenic mechanisms of WDFY3-related neurodevelopmental conditions.
The results are also consistent with findings in other ASD animal models and patients
and suggest an important role for WDFY3 in regulating neuronal function and interconnectivity
in postnatal life."

text: Local adaptation leads to differences between populations within a species.
In many systems, similar environmental contrasts occur repeatedly, sometimes driving
parallel phenotypic evolution. Understanding the genomic basis of local adaptation
and parallel evolution is a major goal of evolutionary genomics. It is now known
that by preventing the break-up of favourable combinations of alleles across multiple
loci, genetic architectures that reduce recombination, like chromosomal inversions,
can make an important contribution to local adaptation. However, little is known
about whether inversions also contribute disproportionately to parallel evolution.
Our aim here is to highlight this knowledge gap, to showcase existing studies,
and to illustrate the differences between genomic architectures with and without
inversions using simple models. We predict that by generating stronger effective
selection, inversions can sometimes speed up the parallel adaptive process or
enable parallel adaptation where it would be impossible otherwise, but this is
highly dependent on the spatial setting. We highlight that further empirical work
is needed, in particular to cover a broader taxonomic range and to understand
the relative importance of inversions compared to genomic regions without inversions.

text: "Objective: MazF is a sequence-specific endoribonuclease-toxin of the MazEF
toxin–antitoxin system. MazF cleaves single-stranded ribonucleic acid (RNA) regions
at adenine–cytosine–adenine (ACA) sequences in the bacterium Escherichia coli.
The MazEF system has been used in various biotechnology and synthetic biology
applications. In this study, we infer how ectopic mazF overexpression affects
production of heterologous proteins. To this end, we quantified the levels of
fluorescent proteins expressed in E. coli from reporters translated from the ACA-containing
or ACA-less messenger RNAs (mRNAs). Additionally, we addressed the impact of the
5′-untranslated region of these reporter mRNAs under the same conditions by comparing
expression from mRNAs that comprise (canonical mRNA) or lack this region (leaderless
mRNA).\r\nResults: Flow cytometry analysis indicates that during mazF overexpression,
fluorescent proteins are translated from the canonical as well as leaderless mRNAs.
Our analysis further indicates that longer mazF overexpression generally increases
the concentration of fluorescent proteins translated from ACA-less mRNAs, however
it also substantially increases bacterial population heterogeneity. Finally, our
results suggest that the strength and duration of mazF overexpression should be
optimized for each experimental setup, to maximize the heterologous protein production
and minimize the amount of phenotypic heterogeneity in bacterial populations,
which is unfavorable in biotechnological processes."

text: The mammalian hippocampal formation (HF) plays a key role in several higher
brain functions, such as spatial coding, learning and memory. Its simple circuit
architecture is often viewed as a trisynaptic loop, processing input originating
from the superficial layers of the entorhinal cortex (EC) and sending it back
to its deeper layers. Here, we show that excitatory neurons in layer 6b of the
mouse EC project to all sub-regions comprising the HF and receive input from the
CA1, thalamus and claustrum. Furthermore, their output is characterized by unique
slow-decaying excitatory postsynaptic currents capable of driving plateau-like
potentials in their postsynaptic targets. Optogenetic inhibition of the EC-6b
pathway affects spatial coding in CA1 pyramidal neurons, while cell ablation impairs
not only acquisition of new spatial memories, but also degradation of previously
acquired ones. Our results provide evidence of a functional role for cortical
layer 6b neurons in the adult brain.

text: Transcription of the ribosomal RNA precursor by RNA polymerase (Pol) I is
a major determinant of cellular growth, and dysregulation is observed in many
cancer types. Here, we present the purification of human Pol I from cells carrying
a genomic GFP fusion on the largest subunit allowing the structural and functional
analysis of the enzyme across species. In contrast to yeast, human Pol I carries
a single-subunit stalk, and in vitro transcription indicates a reduced proofreading
activity. Determination of the human Pol I cryo-EM reconstruction in a close-to-native
state rationalizes the effects of disease-associated mutations and uncovers an
additional domain that is built into the sequence of Pol I subunit RPA1. This
“dock II” domain resembles a truncated HMG box incapable of DNA binding which
may serve as a downstream transcription factor–binding platform in metazoans.
Biochemical analysis, in situ modelling, and ChIP data indicate that Topoisomerase
2a can be recruited to Pol I via the domain and cooperates with the HMG box domain–containing
factor UBF. These adaptations of the metazoan Pol I transcription system may allow
efficient release of positive DNA supercoils accumulating downstream of the transcription
bubble.

text: "To understand how potential gene manipulations affect in vitro microglia,
we provide a set of short protocols to evaluate microglia identity and function.
We detail steps for immunostaining to determine microglia identity. We describe
three functional assays for microglia: phagocytosis, calcium response following
ATP stimulation, and cytokine expression upon inflammatory stimuli. We apply these
protocols to human induced-pluripotent-stem-cell (hiPSC)-derived microglia, but
they can be also applied to other in vitro microglial models including primary
mouse microglia.\r\nFor complete details on the use and execution of this protocol,
please refer to Bartalska et al. (2022).1"

text: Plant root architecture flexibly adapts to changing nitrate (NO3−) availability
in the soil; however, the underlying molecular mechanism of this adaptive development
remains under-studied. To explore the regulation of NO3−-mediated root growth,
we screened for low-nitrate-resistant mutant (lonr) and identified mutants that
were defective in the NAC transcription factor NAC075 (lonr1) as being less sensitive
to low NO3− in terms of primary root growth. We show that NAC075 is a mobile transcription
factor relocating from the root stele tissues to the endodermis based on NO3−
availability. Under low-NO3− availability, the kinase CBL-interacting protein
kinase 1 (CIPK1) is activated, and it phosphorylates NAC075, restricting its movement
from the stele, which leads to the transcriptional regulation of downstream target
WRKY53, consequently leading to adapted root architecture. Our work thus identifies
an adaptive mechanism involving translocation of transcription factor based on
nutrient availability and leading to cell-specific reprogramming of plant root
growth.

text: Germline determination is essential for species survival and evolution in
multicellular organisms. In most flowering plants, formation of the female germline
is initiated with specification of one megaspore mother cell (MMC) in each ovule;
however, the molecular mechanism underlying this key event remains unclear. Here
we report that spatially restricted auxin signaling promotes MMC fate in Arabidopsis.
Our results show that the microRNA160 (miR160) targeted gene ARF17 (AUXIN RESPONSE
FACTOR17) is required for promoting MMC specification by genetically interacting
with the SPL/NZZ (SPOROCYTELESS/NOZZLE) gene. Alterations of auxin signaling cause
formation of supernumerary MMCs in an ARF17- and SPL/NZZ-dependent manner. Furthermore,
miR160 and ARF17 are indispensable for attaining a normal auxin maximum at the
ovule apex via modulating the expression domain of PIN1 (PIN-FORMED1) auxin transporter.
Our findings elucidate the mechanism by which auxin signaling promotes the acquisition
of female germline cell fate in plants.

text: MicroRNA (miRNA) and RNA interference (RNAi) pathways rely on small RNAs produced
by Dicer endonucleases. Mammalian Dicer primarily supports the essential gene-regulating
miRNA pathway, but how it is specifically adapted to miRNA biogenesis is unknown.
We show that the adaptation entails a unique structural role of Dicer’s DExD/H
helicase domain. Although mice tolerate loss of its putative ATPase function,
the complete absence of the domain is lethal because it assures high-fidelity
miRNA biogenesis. Structures of murine Dicer⋅miRNA precursor complexes revealed
that the DExD/H domain has a helicase-unrelated structural function. It locks
Dicer in a closed state, which facilitates miRNA precursor selection. Transition
to a cleavage-competent open state is stimulated by Dicer-binding protein TARBP2.
Absence of the DExD/H domain or its mutations unlocks the closed state, reduces
substrate selectivity, and activates RNAi. Thus, the DExD/H domain structurally
contributes to mammalian miRNA biogenesis and underlies mechanistical partitioning
of miRNA and RNAi pathways.

text: ESCRT-III filaments are composite cytoskeletal polymers that can constrict
and cut cell membranes from the inside of the membrane neck. Membrane-bound ESCRT-III
filaments undergo a series of dramatic composition and geometry changes in the
presence of an ATP-consuming Vps4 enzyme, which causes stepwise changes in the
membrane morphology. We set out to understand the physical mechanisms involved
in translating the changes in ESCRT-III polymer composition into membrane deformation.
We have built a coarse-grained model in which ESCRT-III polymers of different
geometries and mechanical properties are allowed to copolymerise and bind to a
deformable membrane. By modelling ATP-driven stepwise depolymerisation of specific
polymers, we identify mechanical regimes in which changes in filament composition
trigger the associated membrane transition from a flat to a buckled state, and
then to a tubule state that eventually undergoes scission to release a small cargo-loaded
vesicle. We then characterise how the location and kinetics of polymer loss affects
the extent of membrane deformation and the efficiency of membrane neck scission.
Our results identify the near-minimal mechanical conditions for the operation
of shape-shifting composite polymers that sever membrane necks.

text: Models of transcriptional regulation that assume equilibrium binding of transcription
factors have been less successful at predicting gene expression from sequence
in eukaryotes than in bacteria. This could be due to the non-equilibrium nature
of eukaryotic regulation. Unfortunately, the space of possible non-equilibrium
mechanisms is vast and predominantly uninteresting. The key question is therefore
how this space can be navigated efficiently, to focus on mechanisms and models
that are biologically relevant. In this review, we advocate for the normative
role of theory—theory that prescribes rather than just describes—in providing
such a focus. Theory should expand its remit beyond inferring mechanistic models
from data, towards identifying non-equilibrium gene regulatory schemes that may
have been evolutionarily selected, despite their energy consumption, because they
are precise, reliable, fast, or otherwise outperform regulation at equilibrium.
We illustrate our reasoning by toy examples for which we provide simulation code.

text: 'Polygenic adaptation is thought to be ubiquitous, yet remains poorly understood.
Here, we model this process analytically, in the plausible setting of a highly
polygenic, quantitative trait that experiences a sudden shift in the fitness optimum.
We show how the mean phenotype changes over time, depending on the effect sizes
of loci that contribute to variance in the trait, and characterize the allele
dynamics at these loci. Notably, we describe the two phases of the allele dynamics:
The first is a rapid phase, in which directional selection introduces small frequency
differences between alleles whose effects are aligned with or opposed to the shift,
ultimately leading to small differences in their probability of fixation during
a second, longer phase, governed by stabilizing selection. As we discuss, key
results should hold in more general settings and have important implications for
efforts to identify the genetic basis of adaptation in humans and other species.'

text: The inadequate understanding of the mechanisms that reversibly convert molecular
sulfur (S) into lithium sulfide (Li2S) via soluble polysulfides
(PSs) formation impedes the development of high-performance lithium-sulfur (Li-S)
batteries with non-aqueous electrolyte solutions. Here, we use operando small
and wide angle X-ray scattering and operando small angle neutron scattering (SANS)
measurements to track the nucleation, growth and dissolution of solid deposits
from atomic to sub-micron scales during real-time Li-S cell operation. In particular,
stochastic modelling based on the SANS data allows quantifying the nanoscale phase
evolution during battery cycling. We show that next to nano-crystalline Li2S
the deposit comprises solid short-chain PSs particles. The analysis of the experimental
data suggests that initially, Li2S2
precipitates from the solution and then is partially converted via solid-state
electroreduction to Li2S. We further demonstrate that mass
transport, rather than electron transport through a thin passivating film, limits
the discharge capacity and rate performance in Li-S cells.

text: The development dynamics and self-organization of glandular branched epithelia
is of utmost importance for our understanding of diverse processes ranging from
normal tissue growth to the growth of cancerous tissues. Using single primary
murine pancreatic ductal adenocarcinoma (PDAC) cells embedded in a collagen matrix
and adapted media supplementation, we generate organoids that self-organize into
highly branched structures displaying a seamless lumen connecting terminal end
buds, replicating in vivo PDAC architecture. We identify distinct morphogenesis
phases, each characterized by a unique pattern of cell invasion, matrix deformation,
protein expression, and respective molecular dependencies. We propose a minimal
theoretical model of a branching and proliferating tissue, capturing the dynamics
of the first phases. Observing the interaction of morphogenesis, mechanical environment
and gene expression in vitro sets a benchmark for the understanding of self-organization
processes governing complex organoid structure formation processes and branching
morphogenesis.

text: Muskelin (Mkln1) is implicated in neuronal function, regulating plasma membrane
receptor trafficking. However, its influence on intrinsic brain activity and corresponding
behavioral processes remains unclear. Here we show that murine Mkln1
knockout causes non-habituating locomotor activity, increased exploratory drive,
and decreased locomotor response to amphetamine. Muskelin deficiency impairs social
novelty detection while promoting the retention of spatial reference memory and
fear extinction recall. This is strongly mirrored in either weaker or stronger
resting-state functional connectivity between critical circuits mediating locomotor
exploration and cognition. We show that Mkln1 deletion
alters dendrite branching and spine structure, coinciding with enhanced AMPAR-mediated
synaptic transmission but selective impairment in synaptic potentiation maintenance.
We identify muskelin at excitatory synapses and highlight its role in regulating
dendritic spine actin stability. Our findings point to aberrant spine actin modulation
and changes in glutamatergic synaptic function as critical mechanisms that contribute
to the neurobehavioral phenotype arising from Mkln1
ablation.

text: Upon the initiation of collective cell migration, the cells at the free edge
are specified as leader cells; however, the mechanism underlying the leader cell
specification remains elusive. Here, we show that lamellipodial extension after
the release from mechanical confinement causes sustained extracellular signal-regulated
kinase (ERK) activation and underlies the leader cell specification. Live-imaging
of Madin-Darby canine kidney (MDCK) cells and mouse epidermis through the use
of Förster resonance energy transfer (FRET)-based biosensors showed that leader
cells exhibit sustained ERK activation in a hepatocyte growth factor (HGF)-dependent
manner. Meanwhile, follower cells exhibit oscillatory ERK activation waves in
an epidermal growth factor (EGF) signaling-dependent manner. Lamellipodial extension
at the free edge increases the cellular sensitivity to HGF. The HGF-dependent
ERK activation, in turn, promotes lamellipodial extension, thereby forming a positive
feedback loop between cell extension and ERK activation and specifying the cells
at the free edge as the leader cells. Our findings show that the integration of
physical and biochemical cues underlies the leader cell specification during collective
cell migration.

text: Biological systems are the sum of their dynamic three-dimensional (3D) parts.
Therefore, it is critical to study biological structures in 3D and at high resolution
to gain insights into their physiological functions. Electron microscopy of metal
replicas of unroofed cells and isolated organelles has been a key technique to
visualize intracellular structures at nanometer resolution. However, many of these
methods require specialized equipment and personnel to complete them. Here, we
present novel accessible methods to analyze biological structures in unroofed
cells and biochemically isolated organelles in 3D and at nanometer resolution,
focusing on Arabidopsis clathrin-coated vesicles (CCVs). While CCVs are essential
trafficking organelles, their detailed structural information is lacking due to
their poor preservation when observed via classical electron microscopy protocols
experiments. First, we establish a method to visualize CCVs in unroofed cells
using scanning transmission electron microscopy tomography, providing sufficient
resolution to define the clathrin coat arrangements. Critically, the samples are
prepared directly on electron microscopy grids, removing the requirement to use
extremely corrosive acids, thereby enabling the use of this method in any electron
microscopy lab. Secondly, we demonstrate that this standardized sample preparation
allows the direct comparison of isolated CCV samples with those visualized in
cells. Finally, to facilitate the high-throughput and robust screening of metal
replicated samples, we provide a deep learning analysis method to screen the “pseudo
3D” morphologies of CCVs imaged with 2D modalities. Collectively, our work establishes
accessible ways to examine the 3D structure of biological samples and provide
novel insights into the structure of plant CCVs.

text: 'Dose–response relationships are a general concept for quantitatively describing
biological systems across multiple scales, from the molecular to the whole-cell
level. A clinically relevant example is the bacterial growth response to antibiotics,
which is routinely characterized by dose–response curves. The shape of the dose–response
curve varies drastically between antibiotics and plays a key role in treatment,
drug interactions, and resistance evolution. However, the mechanisms shaping the
dose–response curve remain largely unclear. Here, we show in Escherichia coli
that the distinctively shallow dose–response curve of the antibiotic trimethoprim
is caused by a negative growth-mediated feedback loop: Trimethoprim slows growth,
which in turn weakens the effect of this antibiotic. At the molecular level, this
feedback is caused by the upregulation of the drug target dihydrofolate reductase
(FolA/DHFR). We show that this upregulation is not a specific response to trimethoprim
but follows a universal trend line that depends primarily on the growth rate,
irrespective of its cause. Rewiring the feedback loop alters the dose–response
curve in a predictable manner, which we corroborate using a mathematical model
of cellular resource allocation and growth. Our results indicate that growth-mediated
feedback loops may shape drug responses more generally and could be exploited
to design evolutionary traps that enable selection against drug resistance.'
