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,

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: Glaciers in High Mountain Asia generate meltwater that supports the water
needs of 250 million people, but current knowledge of annual accumulation and
ablation is limited to sparse field measurements biased in location and glacier
size. Here, we present altitudinally-resolved specific mass balances (surface,
internal, and basal combined) for 5527 glaciers in High Mountain Asia for 2000–2016,
derived by correcting observed glacier thinning patterns for mass redistribution
due to ice flow. We find that 41% of glaciers accumulated mass over less than
20% of their area, and only 60% ± 10% of regional annual ablation was compensated
by accumulation. Even without 21st century warming, 21% ± 1% of ice volume will
be lost by 2100 due to current climatic-geometric imbalance, representing a reduction
in glacier ablation into rivers of 28% ± 1%. The ablation of glaciers in the Himalayas
and Tien Shan was mostly unsustainable and ice volume in these regions will reduce
by at least 30% by 2100. The most important and vulnerable glacier-fed river basins
(Amu Darya, Indus, Syr Darya, Tarim Interior) were supplied with >50% sustainable
glacier ablation but will see long-term reductions in ice mass and glacier meltwater
supply regardless of the Karakoram Anomaly.

text: Gene expression levels are influenced by multiple coexisting molecular mechanisms.
Some of these interactions such as those of transcription factors and promoters
have been studied extensively. However, predicting phenotypes of gene regulatory
networks (GRNs) remains a major challenge. Here, we use a well-defined synthetic
GRN to study in Escherichia coli how network phenotypes depend on local genetic
context, i.e. the genetic neighborhood of a transcription factor and its relative
position. We show that one GRN with fixed topology can display not only quantitatively
but also qualitatively different phenotypes, depending solely on the local genetic
context of its components. Transcriptional read-through is the main molecular
mechanism that places one transcriptional unit (TU) within two separate regulons
without the need for complex regulatory sequences. We propose that relative order
of individual TUs, with its potential for combinatorial complexity, plays an important
role in shaping phenotypes of GRNs.

text: We report the complete analysis of a deterministic model of deleterious mutations
and negative selection against them at two haploid loci without recombination.
As long as mutation is a weaker force than selection, mutant alleles remain rare
at the only stable equilibrium, and otherwise, a variety of dynamics are possible.
If the mutation-free genotype is absent, generally the only stable equilibrium
is the one that corresponds to fixation of the mutant allele at the locus where
it is less deleterious. This result suggests that fixation of a deleterious allele
that follows a click of the Muller’s ratchet is governed by natural selection,
instead of random drift.

text: 'Self-assembly of nanoparticles can be mediated by polymers, but has so far
led almost exclusively to nanoparticle aggregates that are amorphous. Here, we
employed Coulombic interactions to generate a range of composite materials from
mixtures of charged nanoparticles and oppositely charged polymers. The assembly
behavior of these nanoparticle/polymer composites depends on their order of addition:
polymers added to nanoparticles give rise to stable aggregates, but nanoparticles
added to polymers disassemble the initially formed aggregates. The amorphous aggregates
were transformed into crystalline ones by transiently increasing the ionic strength
of the solution. The morphology of the resulting crystals depended on the length
of the polymer: short polymer chains mediated the self-assembly of nanoparticles
into strongly faceted crystals, whereas long chains led to pseudospherical nanoparticle/polymer
assemblies, within which the crystalline order of nanoparticles was retained.'

text: The C-terminal domain (CTD) of the largest subunit of RNA polymerase II (Pol
II) is a regulatory hub for transcription and RNA processing. Here, we identify
PHD-finger protein 3 (PHF3) as a regulator of transcription and mRNA stability
that docks onto Pol II CTD through its SPOC domain. We characterize SPOC as a
CTD reader domain that preferentially binds two phosphorylated Serine-2 marks
in adjacent CTD repeats. PHF3 drives liquid-liquid phase separation of phosphorylated
Pol II, colocalizes with Pol II clusters and tracks with Pol II across the length
of genes. PHF3 knock-out or SPOC deletion in human cells results in increased
Pol II stalling, reduced elongation rate and an increase in mRNA stability, with
marked derepression of neuronal genes. Key neuronal genes are aberrantly expressed
in Phf3 knock-out mouse embryonic stem cells, resulting in impaired neuronal differentiation.
Our data suggest that PHF3 acts as a prominent effector of neuronal gene regulation
by bridging transcription with mRNA decay.

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: 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: Flowering plants utilize small RNA molecules to guide DNA methyltransferases
to genomic sequences. This RNA-directed DNA methylation (RdDM) pathway preferentially
targets euchromatic transposable elements. However, RdDM is thought to be recruited
by methylation of histone H3 at lysine 9 (H3K9me), a hallmark of heterochromatin.
How RdDM is targeted to euchromatin despite an affinity for H3K9me is unclear.
Here we show that loss of histone H1 enhances heterochromatic RdDM, preferentially
at nucleosome linker DNA. Surprisingly, this does not require SHH1, the RdDM component
that binds H3K9me. Furthermore, H3K9me is dispensable for RdDM, as is CG DNA methylation.
Instead, we find that non-CG methylation is specifically associated with small
RNA biogenesis, and without H1 small RNA production quantitatively expands to
non-CG methylated loci. Our results demonstrate that H1 enforces the separation
of euchromatic and heterochromatic DNA methylation pathways by excluding the small
RNA-generating branch of RdDM from non-CG methylated heterochromatin.

text: De novo loss of function mutations in the ubiquitin ligase-encoding gene Cullin3
lead to autism spectrum disorder (ASD). In mouse, constitutive haploinsufficiency
leads to motor coordination deficits as well as ASD-relevant social and cognitive
impairments. However, induction of Cul3 haploinsufficiency later in life does
not lead to ASD-relevant behaviors, pointing to an important role of Cul3 during
a critical developmental window. Here we show that Cul3 is essential to regulate
neuronal migration and, therefore, constitutive Cul3 heterozygous mutant mice
display cortical lamination abnormalities. At the molecular level, we found that
Cul3 controls neuronal migration by tightly regulating the amount of Plastin3
(Pls3), a previously unrecognized player of neural migration. Furthermore, we
found that Pls3 cell-autonomously regulates cell migration by regulating actin
cytoskeleton organization, and its levels are inversely proportional to neural
migration speed. Finally, we provide evidence that cellular phenotypes associated
with autism-linked gene haploinsufficiency can be rescued by transcriptional activation
of the intact allele in vitro, offering a proof of concept for a potential therapeutic
approach for ASDs.

text: Inositol hexakisphosphate (IP6) is an assembly cofactor for HIV-1. We report
here that IP6 is also used for assembly of Rous sarcoma virus (RSV), a retrovirus
from a different genus. IP6 is ~100-fold more potent at promoting RSV mature capsid
protein (CA) assembly than observed for HIV-1 and removal of IP6 in cells reduces
infectivity by 100-fold. Here, visualized by cryo-electron tomography and subtomogram
averaging, mature capsid-like particles show an IP6-like density in the CA hexamer,
coordinated by rings of six lysines and six arginines. Phosphate and IP6 have
opposing effects on CA in vitro assembly, inducing formation of T = 1 icosahedrons
and tubes, respectively, implying that phosphate promotes pentamer and IP6 hexamer
formation. Subtomogram averaging and classification optimized for analysis of
pleomorphic retrovirus particles reveal that the heterogeneity of mature RSV CA
polyhedrons results from an unexpected, intrinsic CA hexamer flexibility. In contrast,
the CA pentamer forms rigid units organizing the local architecture. These different
features of hexamers and pentamers determine the structural mechanism to form
CA polyhedrons of variable shape in mature RSV particles.

text: The hexameric AAA-ATPase Drg1 is a key factor in eukaryotic ribosome biogenesis
and initiates cytoplasmic maturation of the large ribosomal subunit by releasing
the shuttling maturation factor Rlp24. Drg1 monomers contain two AAA-domains (D1
and D2) that act in a concerted manner. Rlp24 release is inhibited by the drug
diazaborine which blocks ATP hydrolysis in D2. The mode of inhibition was unknown.
Here we show the first cryo-EM structure of Drg1 revealing the inhibitory mechanism.
Diazaborine forms a covalent bond to the 2′-OH of the nucleotide in D2, explaining
its specificity for this site. As a consequence, the D2 domain is locked in a
rigid, inactive state, stalling the whole Drg1 hexamer. Resistance mechanisms
identified include abolished drug binding and altered positioning of the nucleotide.
Our results suggest nucleotide-modifying compounds as potential novel inhibitors
for AAA-ATPases.
