text: Root gravitropic bending represents a fundamental aspect of terrestrial plant
physiology. Gravity is perceived by sedimentation of starch-rich plastids (statoliths)
to the bottom of the central root cap cells. Following gravity perception, intercellular
auxin transport is redirected downwards leading to an asymmetric auxin accumulation
at the lower root side causing inhibition of cell expansion, ultimately resulting
in downwards bending. How gravity-induced statoliths repositioning is translated
into asymmetric auxin distribution remains unclear despite PIN auxin efflux carriers
and the Negative Gravitropic Response of roots (NGR) proteins polarize along statolith
sedimentation, thus providing a plausible mechanism for auxin flow redirection.
In this study, using a functional NGR1-GFP construct, we visualized the NGR1 localization
on the statolith surface and plasma membrane (PM) domains in close proximity to
the statoliths, correlating with their movements. We determined that NGR1 binding
to these PM domains is indispensable for NGR1 functionality and relies on cysteine
acylation and adjacent polybasic regions as well as on lipid and sterol PM composition.
Detailed timing of the early events following graviperception suggested that both
NGR1 repolarization and initial auxin asymmetry precede the visible PIN3 polarization.
This discrepancy motivated us to unveil a rapid, NGR-dependent translocation of
PIN-activating AGCVIII kinase D6PK towards lower PMs of gravity-perceiving cells,
thus providing an attractive model for rapid redirection of auxin fluxes following
gravistimulation.

text: The GNOM (GN) Guanine nucleotide Exchange Factor for ARF small GTPases (ARF-GEF)
is among the best studied trafficking regulators in plants, playing crucial and
unique developmental roles in patterning and polarity. The current models place
GN at the Golgi apparatus (GA), where it mediates secretion/recycling, and at
the plasma membrane (PM) presumably contributing to clathrin-mediated endocytosis
(CME). The mechanistic basis of the developmental function of GN, distinct from
the other ARF-GEFs including its closest homologue GNOM-LIKE1 (GNL1), remains
elusive. Insights from this study largely extend the current notions of GN function.
We show that GN, but not GNL1, localizes to the cell periphery at long-lived structures
distinct from clathrin-coated pits, while CME and secretion proceed normally in
gn knockouts. The functional GN mutant variant GNfewerroots,
absent from the GA, suggests that the cell periphery is the major site of GN action
responsible for its developmental function. Following inhibition by Brefeldin
A, GN, but not GNL1, relocates to the PM likely on exocytic vesicles, suggesting
selective molecular associations en route to the cell periphery. A study of GN-GNL1
chimeric ARF-GEFs indicates that all GN domains contribute to the specific GN
function in a partially redundant manner. Together, this study offers significant
steps toward the elucidation of the mechanism underlying unique cellular and development
functions of GNOM.

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: '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.'

abstract:

text: With increasing urbanization and industrialization, the prevalence of inflammatory
bowel diseases (IBDs) has steadily been rising over the past two decades. IBD
involves flares of gastrointestinal (GI) inflammation accompanied by microbiota
perturbations. However, microbial mechanisms that trigger such flares remain elusive.
Here, we analyzed the association of the emerging pathogen atypical enteropathogenic
E. coli (aEPEC) with IBD disease activity. The presence of diarrheagenic E. coli
was assessed in stool samples from 630 IBD patients and 234 age- and sex-matched
controls without GI symptoms. Microbiota was analyzed with 16S ribosomal RNA gene
amplicon sequencing, and 57 clinical aEPEC isolates were subjected to whole-genome
sequencing and in vitro pathogenicity experiments including biofilm formation,
epithelial barrier function and the ability to induce pro-inflammatory signaling.
The presence of aEPEC correlated with laboratory, clinical and endoscopic disease
activity in ulcerative colitis (UC), as well as microbiota dysbiosis. In vitro,
aEPEC strains induce epithelial p21-activated kinases, disrupt the epithelial
barrier and display potent biofilm formation. The effector proteins espV and espG2
distinguish aEPEC cultured from UC and Crohn’s disease patients, respectively.
EspV-positive aEPEC harbor more virulence factors and have a higher pro-inflammatory
potential, which is counteracted by 5-ASA. aEPEC may tip a fragile immune–microbiota
homeostasis and thereby contribute to flares in UC. aEPEC isolates from UC patients
display properties to disrupt the epithelial barrier and to induce pro-inflammatory
signaling in vitro.

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.'

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: With more than 80 members worldwide, the Orthobunyavirus genus in the Peribunyaviridae
family is a large genus of enveloped RNA viruses, many of which are emerging pathogens
in humans and livestock. How orthobunyaviruses (OBVs) penetrate and infect mammalian
host cells remains poorly characterized. Here, we investigated the entry mechanisms
of the OBV Germiston (GERV). Viral particles were visualized by cryo-electron
microscopy and appeared roughly spherical with an average diameter of 98 nm. Labeling
of the virus with fluorescent dyes did not adversely affect its infectivity and
allowed the monitoring of single particles in fixed and live cells. Using this
approach, we found that endocytic internalization of bound viruses was asynchronous
and occurred within 30-40 min. The virus entered Rab5a+ early endosomes and, subsequently,
late endosomal vacuoles containing Rab7a but not LAMP-1. Infectious entry did
not require proteolytic cleavage, and endosomal acidification was sufficient and
necessary for viral fusion. Acid-activated penetration began 15-25 min after initiation
of virus internalization and relied on maturation of early endosomes to late endosomes.
The optimal pH for viral membrane fusion was slightly below 6.0, and penetration
was hampered when the potassium influx was abolished. Overall, our study provides
real-time visualization of GERV entry into host cells and demonstrates the importance
of late endosomal maturation in facilitating OBV penetration.

text: Several promising strategies based on combining or cycling different antibiotics
have been proposed to increase efficacy and counteract resistance evolution, but
we still lack a deep understanding of the physiological responses and genetic
mechanisms that underlie antibiotic interactions and the clinical applicability
of these strategies. In antibiotic-exposed bacteria, the combined effects of physiological
stress responses and emerging resistance mutations (occurring at different time
scales) generate complex and often unpredictable dynamics. In this Review, we
present our current understanding of bacterial cell physiology and genetics of
responses to antibiotics. We emphasize recently discovered mechanisms of synergistic
and antagonistic drug interactions, hysteresis in temporal interactions between
antibiotics that arise from microbial physiology and interactions between antibiotics
and resistance mutations that can cause collateral sensitivity or cross-resistance.
We discuss possible connections between the different phenomena and indicate relevant
research directions. A better and more unified understanding of drug and genetic
interactions is likely to advance antibiotic therapy.

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.

conducive to their replication. Here we show that replication factories of rotaviruses
represent protein‐RNA condensates that are formed via liquid–liquid phase separation
of the viroplasm‐forming proteins NSP5 and rotavirus RNA chaperone NSP2. Upon
mixing, these proteins readily form condensates at physiologically relevant low
micromolar concentrations achieved in the cytoplasm of virus‐infected cells. Early
infection stage condensates could be reversibly dissolved by 1,6‐hexanediol, as
well as propylene glycol that released rotavirus transcripts from these condensates.
During the early stages of infection, propylene glycol treatments reduced viral
replication and phosphorylation of the condensate‐forming protein NSP5. During
late infection, these condensates exhibited altered material properties and became
resistant to propylene glycol, coinciding with hyperphosphorylation of NSP5. Some
aspects of the assembly of cytoplasmic rotavirus replication factories mirror
the formation of other ribonucleoprotein granules. Such viral RNA‐rich condensates
that support replication of multi‐segmented genomes represent an attractive target
for developing novel therapeutic approaches.

text: Synapses of glutamatergic mossy fibers (MFs) onto cerebellar unipolar brush
cells (UBCs) generate slow excitatory (ON) or inhibitory (OFF) postsynaptic responses
dependent on the complement of glutamate receptors expressed on the UBC’s large
dendritic brush. Using mouse brain slice recording and computational modeling
of synaptic transmission, we found that substantial glutamate is maintained in
the UBC synaptic cleft, sufficient to modify spontaneous firing in OFF UBCs and
tonically desensitize AMPARs of ON UBCs. The source of this ambient glutamate
was spontaneous, spike-independent exocytosis from the MF terminal, and its level
was dependent on activity of glutamate transporters EAAT1–2. Increasing levels
of ambient glutamate shifted the polarity of evoked synaptic responses in ON UBCs
and altered the phase of responses to in vivo-like synaptic activity. Unlike classical
fast synapses, receptors at the UBC synapse are virtually always exposed to a
significant level of glutamate, which varies in a graded manner during transmission.

text: Copper (Cu) is a redox-active micronutrient that is both essential and toxic.
Its cellular homeostasis is critical for supporting cuproprotein maturation while
avoiding excessive oxidative stress. The Cu importer CcoA is the prototype of
the widespread CalT subfamily of the MFS-type transporters. Hence, understanding
its molecular mechanism of function is significant. Here, we show that CcoA undergoes
a thiol:disulfide oxidoreduction cycle, which is important for its Cu import activity.

text: Biotrophic plant pathogens secrete effector proteins to manipulate the host
physiology. Effectors suppress defenses and induce an environment favorable to
disease development. Sequence-based prediction of effector function is impeded
by their rapid evolution rate. In the maize pathogen Ustilago maydis,
effector-coding genes frequently organize in clusters. Here we describe the functional
characterization of the pleiades, a cluster of ten
effector genes, by analyzing the micro- and macroscopic phenotype of the cluster
deletion and expressing these proteins in planta. Deletion
of the pleiades leads to strongly impaired virulence
and accumulation of reactive oxygen species (ROS) in infected tissue. Eight of
the Pleiades suppress the production of ROS upon perception of pathogen associated
molecular patterns (PAMPs). Although functionally redundant, the Pleiades target
different host components. The paralogs Taygeta1 and Merope1 suppress ROS production
in either the cytoplasm or nucleus, respectively. Merope1 targets and promotes
the auto-ubiquitination activity of RFI2, a conserved family of E3 ligases that
regulates the production of PAMP-triggered ROS burst in plants.

text: Understanding interactions between antibiotics used in combination is an important
theme in microbiology. Using the interactions between the antifolate drug trimethoprim
and the ribosome-targeting antibiotic erythromycin in Escherichia coli as a model,
we applied a transcriptomic approach for dissecting interactions between two antibiotics
with different modes of action. When trimethoprim and erythromycin were combined,
the transcriptional response of genes from the sulfate reduction pathway deviated
from the dominant effect of trimethoprim on the transcriptome. We successfully
altered the drug interaction from additivity to suppression by increasing the
sulfate level in the growth environment and identified sulfate reduction as an
important metabolic determinant that shapes the interaction between the two drugs.
Our work highlights the potential of using prioritization of gene expression patterns
as a tool for identifying key metabolic determinants that shape drug-drug interactions.
We further demonstrated that the sigma factor-binding protein gene crl shapes
the interactions between the two antibiotics, which provides a rare example of
how naturally occurring variations between strains of the same bacterial species
can sometimes generate very different drug interactions.

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: 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: Mammalian circadian rhythms are generated by a transcription-based feedback
loop in which CLOCK:BMAL1 drives transcription of its repressors (PER1/2, CRY1/2),
which ultimately interact with CLOCK:BMAL1 to close the feedback loop with ~24
hr periodicity. Here we pinpoint a key difference between CRY1 and CRY2 that underlies
their differential strengths as transcriptional repressors. Both cryptochromes
bind the BMAL1 transactivation domain similarly to sequester it from coactivators
and repress CLOCK:BMAL1 activity. However, we find that CRY1 is recruited with
much higher affinity to the PAS domain core of CLOCK:BMAL1, allowing it to serve
as a stronger repressor that lengthens circadian period. We discovered a dynamic
serine-rich loop adjacent to the secondary pocket in the photolyase homology region
(PHR) domain that regulates differential binding of cryptochromes to the PAS domain
core of CLOCK:BMAL1. Notably, binding of the co-repressor PER2 remodels the serine
loop of CRY2, making it more CRY1-like and enhancing its affinity for CLOCK:BMAL1.
