text: Retroviruses assemble and bud from infected cells in an immature form and
require proteolytic maturation for infectivity. The CA (capsid) domains of the
Gag polyproteins assemble a protein lattice as a truncated sphere in the immature
virion. Proteolytic cleavage of Gag induces dramatic structural rearrangements;
a subset of cleaved CA subsequently assembles into the mature core, whose architecture
varies among retroviruses. Murine leukemia virus (MLV) is the prototypical γ-retrovirus
and serves as the basis of retroviral vectors, but the structure of the MLV CA
layer is unknown. Here we have combined X-ray crystallography with cryoelectron
tomography to determine the structures of immature and mature MLV CA layers within
authentic viral particles. This reveals the structural changes associated with
maturation, and, by comparison with HIV-1, uncovers conserved and variable features.
In contrast to HIV-1, most MLV CA is used for assembly of the mature core, which
adopts variable, multilayered morphologies and does not form a closed structure.
Unlike in HIV-1, there is similarity between protein–protein interfaces in the
immature MLV CA layer and those in the mature CA layer, and structural maturation
of MLV could be achieved through domain rotations that largely maintain hexameric
interactions. Nevertheless, the dramatic architectural change on maturation indicates
that extensive disassembly and reassembly are required for mature core growth.
The core morphology suggests that wrapping of the genome in CA sheets may be sufficient
to protect the MLV ribonucleoprotein during cell entry.

text: Plant organs are typically organized into three main tissue layers. The middle
ground tissue layer comprises the majority of the plant body and serves a wide
range of functions, including photosynthesis, selective nutrient uptake and storage,
and gravity sensing. Ground tissue patterning and maintenance in Arabidopsis are
controlled by a well-established gene network revolving around the key regulator
SHORT-ROOT (SHR). In contrast, it is completely unknown how ground tissue identity
is first specified from totipotent precursor cells in the embryo. The plant signaling
molecule auxin, acting through AUXIN RESPONSE FACTOR (ARF) transcription factors,
is critical for embryo patterning. The auxin effector ARF5/MONOPTEROS (MP) acts
both cell-autonomously and noncell-autonomously to control embryonic vascular
tissue formation and root initiation, respectively. Here we show that auxin response
and ARF activity cell-autonomously control the asymmetric division of the first
ground tissue cells. By identifying embryonic target genes, we show that MP transcriptionally
initiates the ground tissue lineage and acts upstream of the regulatory network
that controls ground tissue patterning and maintenance. Strikingly, whereas the
SHR network depends on MP, this MP function is, at least in part, SHR independent.
Our study therefore identifies auxin response as a regulator of ground tissue
specification in the embryonic root, and reveals that ground tissue initiation
and maintenance use different regulators and mechanisms. Moreover, our data provide
a framework for the simultaneous formation of multiple cell types by the same
transcriptional regulator.

text: Growing microtubules are protected from depolymerization by the presence of
a GTP or GDP/Pi cap. End-binding proteins of the EB1 family bind to the stabilizing
cap, allowing monitoring of its size in real time. The cap size has been shown
to correlate with instantaneous microtubule stability. Here we have quantitatively
characterized the properties of cap size fluctuations during steadystate growth
and have developed a theory predicting their timescale and amplitude from the
kinetics of microtubule growth and cap maturation. In contrast to growth speed
fluctuations, cap size fluctuations show a characteristic timescale, which is
defined by the lifetime of the cap sites. Growth fluctuations affect the amplitude
of cap size fluctuations; however, cap size does not affect growth speed, indicating
that microtubules are far from instability during most of their time of growth.
Our theory provides the basis for a quantitative understanding of microtubule
stability fluctuations during steady-state growth.

text: Humans routinely use conditionally cooperative strategies when interacting
in repeated social dilemmas. They are more likely to cooperate if others cooperated
before, and are ready to retaliate if others defected. To capture the emergence
of reciprocity, most previous models consider subjects who can only choose from
a restricted set of representative strategies, or who react to the outcome of
the very last round only. As players memorize more rounds, the dimension of the
strategy space increases exponentially. This increasing computational complexity
renders simulations for individuals with higher cognitive abilities infeasible,
especially if multiplayer interactions are taken into account. Here, we take an
axiomatic approach instead. We propose several properties that a robust cooperative
strategy for a repeated multiplayer dilemma should have. These properties naturally
lead to a unique class of cooperative strategies, which contains the classical
Win-Stay Lose-Shift rule as a special case. A comprehensive numerical analysis
for the prisoner's dilemma and for the public goods game suggests that strategies
of this class readily evolve across various memory-n spaces. Our results reveal
that successful strategies depend not only on how cooperative others were in the
past but also on the respective context of cooperation.

text: 'Many central synapses contain a single presynaptic active zone and a single
postsynaptic density. Vesicular release statistics at such “simple synapses” indicate
that they contain a small complement of docking sites where vesicles repetitively
dock and fuse. In this work, we investigate functional and morphological aspects
of docking sites at simple synapses made between cerebellar parallel fibers and
molecular layer interneurons. Using immunogold labeling of SDS-treated freeze-fracture
replicas, we find that Cav2.1 channels form several clusters per active zone with
about nine channels per cluster. The mean value and range of intersynaptic variation
are similar for Cav2.1 cluster numbers and for functional estimates of docking-site
numbers obtained from the maximum numbers of released vesicles per action potential.
Both numbers grow in relation with synaptic size and decrease by a similar extent
with age between 2 wk and 4 wk postnatal. Thus, the mean docking-site numbers
were 3.15 at 2 wk (range: 1–10) and 2.03 at 4 wk (range: 1–4), whereas the mean
numbers of Cav2.1 clusters were 2.84 at 2 wk (range: 1–8) and 2.37 at 4 wk (range:
1–5). These changes were accompanied by decreases of miniature current amplitude
(from 93 pA to 56 pA), active-zone surface area (from 0.0427 μm2 to 0.0234 μm2),
and initial success rate (from 0.609 to 0.353), indicating a tightening of synaptic
transmission with development. Altogether, these results suggest a close correspondence
between the number of functionally defined vesicular docking sites and that of
clusters of voltage-gated calcium channels. '

text: 'In antagonistic symbioses, such as host–parasite interactions, one population’s
success is the other’s loss. In mutualistic symbioses, such as division of labor,
both parties can gain, but they might have different preferences over the possible
mutualistic arrangements. The rates of evolution of the two populations in a symbiosis
are important determinants of which population will be more successful: Faster
evolution is thought to be favored in antagonistic symbioses (the “Red Queen effect”),
but disfavored in certain mutualistic symbioses (the “Red King effect”). However,
it remains unclear which biological parameters drive these effects. Here, we analyze
the effects of the various determinants of evolutionary rate: generation time,
mutation rate, population size, and the intensity of natural selection. Our main
results hold for the case where mutation is infrequent. Slower evolution causes
a long-term advantage in an important class of mutualistic interactions. Surprisingly,
less intense selection is the strongest driver of this Red King effect, whereas
relative mutation rates and generation times have little effect. In antagonistic
interactions, faster evolution by any means is beneficial. Our results provide
insight into the demographic evolution of symbionts. '

text: Individual computations and social interactions underlying collective behavior
in groups of animals are of great ethological, behavioral, and theoretical interest.
While complex individual behaviors have successfully been parsed into small dictionaries
of stereotyped behavioral modes, studies of collective behavior largely ignored
these findings; instead, their focus was on inferring single, mode-independent
social interaction rules that reproduced macroscopic and often qualitative features
of group behavior. Here, we bring these two approaches together to predict individual
swimming patterns of adult zebrafish in a group. We show that fish alternate between
an “active” mode, in which they are sensitive to the swimming patterns of conspecifics,
and a “passive” mode, where they ignore them. Using a model that accounts for
these two modes explicitly, we predict behaviors of individual fish with high
accuracy, outperforming previous approaches that assumed a single continuous computation
by individuals and simple metric or topological weighing of neighbors’ behavior.
At the group level, switching between active and passive modes is uncorrelated
among fish, but correlated directional swimming behavior still emerges. Our quantitative
approach for studying complex, multi-modal individual behavior jointly with emergent
group behavior is readily extensible to additional behavioral modes and their
neural correlates as well as to other species.

text: 'Polymicrobial infections constitute small ecosystems that accommodate several
bacterial species. Commonly, these bacteria are investigated in isolation. However,
it is unknown to what extent the isolates interact and whether their interactions
alter bacterial growth and ecosystem resilience in the presence and absence of
antibiotics. We quantified the complete ecological interaction network for 72
bacterial isolates collected from 23 individuals diagnosed with polymicrobial
urinary tract infections and found that most interactions cluster based on evolutionary
relatedness. Statistical network analysis revealed that competitive and cooperative
reciprocal interactions are enriched in the global network, while cooperative
interactions are depleted in the individual host community networks. A population
dynamics model parameterized by our measurements suggests that interactions restrict
community stability, explaining the observed species diversity of these communities.
We further show that the clinical isolates frequently protect each other from
clinically relevant antibiotics. Together, these results highlight that ecological
interactions are crucial for the growth and survival of bacteria in polymicrobial
infection communities and affect their assembly and resilience. '
