text: To understand the function of neuronal circuits, it is crucial to disentangle
the connectivity patterns within the network. However, most tools currently used
to explore connectivity have low throughput, low selectivity, or limited accessibility.
Here, we report the development of an improved packaging system for the production
of the highly neurotropic RVdGenvA-CVS-N2c rabies viral vectors, yielding titers
orders of magnitude higher with no background contamination, at a fraction of
the production time, while preserving the efficiency of transsynaptic labeling.
Along with the production pipeline, we developed suites of ‘starter’ AAV and bicistronic
RVdG-CVS-N2c vectors, enabling retrograde labeling from a wide range of neuronal
populations, tailored for diverse experimental requirements. We demonstrate the
power and flexibility of the new system by uncovering hidden local and distal
inhibitory connections in the mouse hippocampal formation and by imaging the functional
properties of a cortical microcircuit across weeks. Our novel production pipeline
provides a convenient approach to generate new rabies vectors, while our toolkit
flexibly and efficiently expands the current capacity to label, manipulate and
image the neuronal activity of interconnected neuronal circuits in vitro and in
vivo.

text: DNA methylation plays essential homeostatic functions in eukaryotic genomes.
In animals, DNA methylation is also developmentally regulated and, in turn, regulates
development. In the past two decades, huge research effort has endorsed the understanding
that DNA methylation plays a similar role in plant development, especially during
sexual reproduction. The power of whole-genome sequencing and cell isolation techniques,
as well as bioinformatics tools, have enabled recent studies to reveal dynamic
changes in DNA methylation during germline development. Furthermore, the combination
of these technological advances with genetics, developmental biology and cell
biology tools has revealed functional methylation reprogramming events that control
gene and transposon activities in flowering plant germlines. In this review, we
discuss the major advances in our knowledge of DNA methylation dynamics during
male and female germline development in flowering plants.

text: Confining molecules within well-defined nanosized spaces can profoundly alter
their physicochemical characteristics. For example, the controlled aggregation
of chromophores into discrete oligomers has been shown to tune their optical properties
whereas encapsulation of reactive species within molecular hosts can increase
their stability. The resazurin/resorufin pair has been widely used for detecting
redox processes in biological settings; yet, how tight confinement affects the
properties of these two dyes remains to be explored. Here, we show that a flexible
PdII6L4 coordination
cage can efficiently encapsulate both resorufin and resazurin in the form of dimers,
dramatically modulating their optical properties. Furthermore, binding within
the cage significantly decreases the reduction rate of resazurin to resorufin,
and the rate of the subsequent reduction of resorufin to dihydroresorufin. During
our studies, we also found that upon dilution, the PdII6L4
cage disassembles to afford PdII2L2
species, which lacks the ability to form inclusion complexes – a process that
can be reversed upon the addition of the strongly binding resorufin/resazurin
guests. We expect that the herein disclosed ability of a water-soluble cage to
reversibly modulate the optical and chemical properties of a molecular redox probe
will expand the versatility of synthetic fluorescent probes in biologically relevant
environments.

text: Molecular confinement effects can profoundly alter the physicochemical properties
of the confined species. A plethora of organic molecules were encapsulated within
the cavities of supramolecular hosts, and the impact of the cavity size and polarity
was widely investigated. However, the extent to which the properties of the confined
guests can be affected by the symmetry of the cage─which dictates the shape of
the cavity─remains to be understood. Here we show that cage symmetry has a dramatic
effect on the equilibrium between two isomers of the encapsulated spiropyran guests.
Working with two Pd-based coordination cages featuring similarly sized but differently
shaped hydrophobic cavities, we found a highly selective stabilization of the
isomer whose shape matches that of the cavity of the cage. A Td-symmetric cage
stabilized the spiropyrans’ colorless form and rendered them photochemically inert.
In contrast, a D2h-symmetric cage favored the colored isomer, while maintaining
reversible photoswitching between the two states of the encapsulated spiropyrans.
We also show that the switching kinetics strongly depend on the substitution pattern
on the spiropyran scaffold. This finding was used to fabricate a time-sensitive
information storage medium with tunable lifetimes of the encoded messages.

text: Confinement within molecular cages can dramatically modify the physicochemical
properties of the encapsulated guest molecules, but such host-guest complexes
have mainly been studied in a static context. Combining confinement effects with
fast guest exchange kinetics could pave the way toward stimuli-responsive supramolecular
systems—and ultimately materials—whose desired properties could be tailored “on
demand” rapidly and reversibly. Here, we demonstrate rapid guest exchange between
inclusion complexes of an open-window coordination cage that can simultaneously
accommodate two guest molecules. Working with two types of guests, anthracene
derivatives and BODIPY dyes, we show that the former can substantially modify
the optical properties of the latter upon noncovalent heterodimer formation. We
also studied the light-induced covalent dimerization of encapsulated anthracenes
and found large effects of confinement on reaction rates. By coupling the photodimerization
with the rapid guest exchange, we developed a new way to modulate fluorescence
using external irradiation.

text: "A species distributed across diverse environments may adapt to local conditions.
We ask how quickly such a species changes its range in response to changed conditions.
Szép et al. (Szép E, Sachdeva H, Barton NH. 2021 Polygenic local adaptation in
metapopulations: a stochastic eco-evolutionary model. Evolution75, 1030–1045 (doi:10.1111/evo.14210))
used the infinite island model to find the stationary distribution of allele frequencies
and deme sizes. We extend this to find how a metapopulation responds to changes
in carrying capacity, selection strength, or migration rate when deme sizes are
fixed. We further develop a ‘fixed-state’ approximation. Under this approximation,
polymorphism is only possible for a narrow range of habitat proportions when selection
is weak compared to drift, but for a much wider range otherwise. When rates of
selection or migration relative to drift change in a single deme of the metapopulation,
the population takes a time of order m−1 to reach the new equilibrium. However,
even with many loci, there can be substantial fluctuations in net adaptation,
because at each locus, alleles randomly get lost or fixed. Thus, in a finite metapopulation,
variation may gradually be lost by chance, even if it would persist in an infinite
metapopulation. When conditions change across the whole metapopulation, there
can be rapid change, which is predicted well by the fixed-state approximation.
This work helps towards an understanding of how metapopulations extend their range
across diverse environments.\r\nThis article is part of the theme issue ‘Species’
ranges in the face of changing environments (Part II)’."

text: Redox mediators could catalyse otherwise slow and energy-inefficient cycling
of Li–S and Li–O2 batteries by shuttling electrons or holes between the electrode
and the solid insulating storage materials. For mediators to work efficiently
they need to oxidize the solid with fast kinetics but with the lowest possible
overpotential. However, the dependence of kinetics and overpotential is unclear,
which hinders informed improvement. Here, we find that when the redox potentials
of mediators are tuned via, for example, Li+ concentration in the electrolyte,
they exhibit distinct threshold potentials, where the kinetics accelerate several-fold
within a range as small as 10 mV. This phenomenon is independent of types of mediator
and electrolyte. The acceleration originates from the overpotentials required
to activate fast Li+/e− extraction and the following chemical step at specific
abundant surface facets. Efficient redox catalysis at insulating solids therefore
requires careful consideration of the surface conditions of the storage materials
and electrolyte-dependent redox potentials, which may be tuned by salt concentrations
or solvents.

text: Mutations in the chromodomain helicase DNA-binding 8 (CHD8) gene are a frequent
cause of autism spectrum disorder (ASD). While its phenotypic spectrum often encompasses
macrocephaly, implicating cortical abnormalities, how CHD8 haploinsufficiency
affects neurodevelopmental is unclear. Here, employing human cerebral organoids,
we find that CHD8 haploinsufficiency disrupted neurodevelopmental trajectories
with an accelerated and delayed generation of, respectively, inhibitory and excitatory
neurons that yields, at days 60 and 120, symmetrically opposite expansions in
their proportions. This imbalance is consistent with an enlargement of cerebral
organoids as an in vitro correlate of patients’ macrocephaly. Through an isogenic
design of patient-specific mutations and mosaic organoids, we define genotype-phenotype
relationships and uncover their cell-autonomous nature. Our results define cell-type-specific
CHD8-dependent molecular defects related to an abnormal program of proliferation
and alternative splicing. By identifying cell-type-specific effects of CHD8 mutations,
our study uncovers reproducible developmental alterations that may be employed
for neurodevelopmental disease modeling.

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: The actin-homologue FtsA is essential for E. coli cell division, as it links
FtsZ filaments in the Z-ring to transmembrane proteins. FtsA is thought to initiate
cell constriction by switching from an inactive polymeric to an active monomeric
conformation, which recruits downstream proteins and stabilizes the Z-ring. However,
direct biochemical evidence for this mechanism is missing. Here, we use reconstitution
experiments and quantitative fluorescence microscopy to study divisome activation
in vitro. By comparing wild-type FtsA with FtsA R286W, we find that this hyperactive
mutant outperforms FtsA WT in replicating FtsZ treadmilling dynamics, FtsZ filament
stabilization and recruitment of FtsN. We could attribute these differences to
a faster exchange and denser packing of FtsA R286W below FtsZ filaments. Using
FRET microscopy, we also find that FtsN binding promotes FtsA self-interaction.
We propose that in the active divisome FtsA and FtsN exist as a dynamic copolymer
that follows treadmilling filaments of FtsZ.

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: Studies of protein fitness landscapes reveal biophysical constraints guiding
protein evolution and empower prediction of functional proteins. However, generalisation
of these findings is limited due to scarceness of systematic data on fitness landscapes
of proteins with a defined evolutionary relationship. We characterized the fitness
peaks of four orthologous fluorescent proteins with a broad range of sequence
divergence. While two of the four studied fitness peaks were sharp, the other
two were considerably flatter, being almost entirely free of epistatic interactions.
Mutationally robust proteins, characterized by a flat fitness peak, were not optimal
templates for machine-learning-driven protein design – instead, predictions were
more accurate for fragile proteins with epistatic landscapes. Our work paves insights
for practical application of fitness landscape heterogeneity in protein engineering.

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,

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.
