text: Cryo-electron tomography combined with image processing by sub-tomogram averaging
is unique in its power to resolve the structures of proteins and macromolecular
complexes in situ. Limitations of the method, including the low signal to noise
ratio within individual images from cryo-tomographic datasets and difficulties
in determining the defocus at which the data was collected, mean that to date
the very best structures obtained by sub-tomogram averaging are limited to a resolution
of approximately 15. Å. Here, by optimizing data collection and defocus determination
steps, we have determined the structure of assembled Mason-Pfizer monkey virus
Gag protein using sub-tomogram averaging to a resolution of 8.5. Å. At this resolution
alpha-helices can be directly and clearly visualized. These data demonstrate for
the first time that high-resolution structural information can be obtained from
cryo-electron tomograms using sub-tomogram averaging. Sub-tomogram averaging has
the potential to allow detailed studies of unsolved and biologically relevant
structures under biologically relevant conditions.

text: Cell migration is commonly accompanied by protrusion of membrane ruffles and
lamellipodia. In two-dimensional migration, protrusion of these thin sheets of
cytoplasm is considered relevant to both exploration of new space and initiation
of nascent adhesion to the substratum. Lamellipodium formation can be potently
stimulated by Rho GTPases of the Rac subfamily, but alsoby RhoG or Cdc42. Here
we describe viable fibroblast cell lines geneticallydeficient for Rac1 that lack
detectable levels of Rac2 and Rac3. Rac-deficient cells were devoid of apparent
lamellipodia, but these structures were restored by expression of either Rac subfamily
member, but not by Cdc42 or RhoG. Cells deficient in Rac showed strong reduction
in wound closure and random cell migration and a notable loss of sensitivity to
a chemotactic gradient. Despite these defects, Rac-deficient cells were able to
spread, formed filopodia and established focal adhesions. Spreading in these cells
was achieved by the extension of filopodia followed by the advancement of cytoplasmic
veils between them. The number and size of focal adhesions as well as their intensity
were largely unaffected by genetic removal of Rac1. However, Rac deficiency increased
the mobility of different components in focal adhesions, potentially explaining
how Rac - although not essential - can contribute to focal adhesion assembly.
Together, our data demonstrate that Rac signaling is essential for lamellipodium
protrusion and for efficient cell migration, but not for spreading or filopodium
formation. Our findings also suggest that Rac GTPases are crucial to the establishment
or maintenance of polarity in chemotactic migration.

text: Lamellipodia are sheet-like protrusions formed during migration or phagocytosis
and comprise a network of actin filaments. Filament formation in this network
is initiated by nucleation/branching through the actin-related protein 2/3 (Arp2/3)
complex downstream of its activator, suppressor of cAMP receptor/WASP-family verprolin
homologous (Scar/WAVE), but the relative relevance of Arp2/3-mediated branching
versus actin filament elongation is unknown. Here we use instantaneous interference
with Arp2/3 complex function in live fibroblasts with established lamellipodia.
This allows direct examination of both the fate of elongating filaments upon instantaneous
suppression of Arp2/3 complex activity and the consequences of this treatment
on the dynamics of other lamellipodial regulators. We show that Arp2/3 complex
is an essential organizer of treadmilling actin filament arrays but has little
effect on the net rate of actin filament turnover at the cell periphery. In addition,
Arp2/3 complex serves as key upstream factor for the recruitment of modulators
of lamellipodia formation such as capping protein or cofilin. Arp2/3 complex is
thus decisive for filament organization and geometry within the network not only
by generating branches and novel filament ends, but also by directing capping
or severing activities to the lamellipodium. Arp2/3 complex is also crucial to
lamellipodia-based migration of keratocytes.

text: "Background: Monoclonal antibodies (mAb), such as trastuzumab are a valuable
addition to breast cancer therapy.\r\nData obtained from neoadjuvant settings
revealed that antibody-dependent cell-mediated cytotoxicity (ADCC) is a\r\nmajor
mechanism of action for the mAb trastuzumab. Conflicting results still call into
question whether disease\r\nprogression, prolonged treatment or concomitant chemotherapy
influences ADCC and related immunological\r\nphenomena.\r\nMethods: We analyzed
the activity of ADCC and antibody-dependent cell-mediated phagocytosis (ADCP)
of\r\nperipheral blood mononuclear cells (PBMCs) from human epidermal growth factor
receptor 2 (HER2/neu) positive\r\nbreast cancer patients receiving trastuzumab
therapy either in an adjuvant (n = 13) or metastatic (n = 15) setting as\r\nwell
as from trastuzumab treatment-naive (t-naive) HER2/neu negative patients (n =
15). PBMCs from healthy volunteers\r\n(n = 24) were used as controls. ADCC and
ADCP activity was correlated with the expression of antibody binding\r\nFc-gamma
receptor (FcγR)I (CD64), FcγRII (CD32) and FcγRIII (CD16) on CD14+ (monocytes)
and CD56+ (NK) cells, as well as the expression of CD107a+ (LAMP-1) on CD56+ cells
and the total amount of CD4+CD25+FOXP3+ (Treg) cells. In metastatic patients,
markers were correlated with progression-free survival (PFS).\r\nResults: ADCC
activity was significantly down regulated in metastatic, adjuvant and t-naive
patient cohorts as compared to healthy controls. Reduced ADCC activity was inversely
correlated with the expression of CD107a on CD56+\r\ncells in adjuvant patients.
ADCC and ADCP activity of the patient cohorts were similar, regardless of treatment
duration\r\nor additional chemotherapy. PFS in metastatic patients inversely correlated
with the number of peripheral Treg cells.\r\nConclusion: The reduction of ADCC
in patients as compared to healthy controls calls for adjuvant strategies, such
as\r\nimmune-enhancing agents, to improve the activity of trastuzumab. However,
efficacy of trastuzumab-specific ADCC\r\nand ADCP appears not to be affected by
treatment duration, disease progression or concomitant chemotherapy. This\r\nfinding
supports the application of trastuzumab at any stage of the disease."

text: As sessile organisms, plants have to be able to adapt to a continuously changing
environment. Plants that perceive some of these changes as stress signals activate
signaling pathways to modulate their development and to enable them to survive.
The complex responses to environmental cues are to a large extent mediated by
plant hormones that together orchestrate the final plant response. The phytohormone
cytokinin is involved in many plant developmental processes. Recently, it has
been established that cytokinin plays an important role in stress responses, but
does not act alone. Indeed, the hormonal control of plant development and stress
adaptation is the outcome of a complex network of multiple synergistic and antagonistic
interactions between various hormones. Here, we review the recent findings on
the cytokinin function as part of this hormonal network. We focus on the importance
of the crosstalk between cytokinin and other hormones, such as abscisic acid,
jasmonate, salicylic acid, ethylene, and auxin in the modulation of plant development
and stress adaptation. Finally, the impact of the current research in the biotechnological
industry will be discussed.

text: The plant root system is essential for providing anchorage to the soil, supplying
minerals and water, and synthesizing metabolites. It is a dynamic organ modulated
by external cues such as environmental signals, water and nutrients availability,
salinity and others. Lateral roots (LRs) are initiated from the primary root post-embryonically,
after which they progress through discrete developmental stages which can be independently
controlled, providing a high level of plasticity during root system formation.
Within this review, main contributions are presented, from the classical forward
genetic screens to the more recent high-throughput approaches, combined with computer
model predictions, dissecting how LRs and thereby root system architecture is
established and developed.

text: Upon hormonal signaling, ovules develop as lateral organs from the placenta.
Ovule numbers ultimately determine the number of seeds that develop, and thereby
contribute to the final seed yield in crop plants. We demonstrate here that CUP-SHAPED
COTYLEDON 1 (CUC1), CUC2 and AINTEGUMENTA (ANT) have additive effects on ovule
primordia formation. We show that expression of the CUC1 and CUC2 genes is required
to redundantly regulate expression of PINFORMED1 (PIN1), which in turn is required
for ovule primordia formation. Furthermore, our results suggest that the auxin
response factor MONOPTEROS (MP/ARF5) may directly bind ANT, CUC1 and CUC2 and
promote their transcription. Based on our findings, we propose an integrative
model to describe the molecular mechanisms of the early stages of ovule development.

text: In Arabidopsis, lateral roots originate from pericycle cells deep within the
primary root. New lateral root primordia (LRP) have to emerge through several
overlaying tissues. Here, we report that auxin produced in new LRP is transported
towards the outer tissues where it triggers cell separation by inducing both the
auxin influx carrier LAX3 and cell-wall enzymes. LAX3 is expressed in just two
cell files overlaying new LRP. To understand how this striking pattern of LAX3
expression is regulated, we developed a mathematical model that captures the network
regulating its expression and auxin transport within realistic three-dimensional
cell and tissue geometries. Our model revealed that, for the LAX3 spatial expression
to be robust to natural variations in root tissue geometry, an efflux carrier
is required--later identified to be PIN3. To prevent LAX3 from being transiently
expressed in multiple cell files, PIN3 and LAX3 must be induced consecutively,
which we later demonstrated to be the case. Our study exemplifies how mathematical
models can be used to direct experiments to elucidate complex developmental processes.

text: Solid-state NMR provides insight into protein motion over time scales ranging
from picoseconds to seconds. While in solution state the methodology to measure
protein dynamics is well established, there is currently no such consensus protocol
for measuring dynamics in solids. In this article, we perform a detailed investigation
of measurement protocols for fast motions, i.e. motions ranging from picoseconds
to a few microseconds, which is the range covered by dipolar coupling and relaxation
experiments. We perform a detailed theoretical investigation how dipolar couplings
and relaxation data can provide information about amplitudes and time scales of
local motion. We show that the measurement of dipolar couplings is crucial for
obtaining accurate motional parameters, while systematic errors are found when
only relaxation data are used. Based on this realization, we investigate how the
REDOR experiment can provide such data in a very accurate manner. We identify
that with accurate rf calibration, and explicit consideration of rf field inhomogeneities,
one can obtain highly accurate absolute order parameters. We then perform joint
model-free analyses of 6 relaxation data sets and dipolar couplings, based on
previously existing, as well as new data sets on microcrystalline ubiquitin. We
show that nanosecond motion can be detected primarily in loop regions, and compare
solid-state data to solution-state relaxation and RDC analyses. The protocols
investigated here will serve as a useful basis towards the establishment of a
routine protocol for the characterization of ps–μs motions in proteins by solid-state
NMR.

text: The transition of proteins from their soluble functional state to amyloid
fibrils and aggregates is associated with the onset of several human diseases.
Protein aggregation often requires some structural reshaping and the subsequent
formation of intermolecular contacts. Therefore, the study of the conformation
of excited protein states and their ability to form oligomers is of primary importance
for understanding the molecular basis of amyloid fibril formation. Here, we investigated
the oligomerization processes that occur along the folding of the amyloidogenic
human protein β2-microglobulin. The combination of real-time two-dimensional NMR
data with real-time small-angle X-ray scattering measurements allowed us to derive
thermodynamic and kinetic information on protein oligomerization of different
conformational states populated along the folding pathways. In particular, we
could demonstrate that a long-lived folding intermediate (I-state) has a higher
propensity to oligomerize compared to the native state. Our data agree well with
a simple five-state kinetic model that involves only monomeric and dimeric species.
The dimers have an elongated shape with the dimerization interface located at
the apical side of β2-microglobulin close to Pro32, the residue that has a trans
conformation in the I-state and a cis conformation in the native (N) state. Our
experimental data suggest that partial unfolding in the apical half of the protein
close to Pro32 leads to an excited state conformation with enhanced propensity
for oligomerization. This excited state becomes more populated in the transient
I-state due to the destabilization of the native conformation by the trans-Pro32
configuration.

text: 'Background: Genetic variation at the melanocortin-1 receptor (MC1R) gene
is correlated with melanin color variation in many birds. Feral pigeons (Columba
livia) show two major melanin-based colorations: a red coloration due to pheomelanic
pigment and a black coloration due to eumelanic pigment. Furthermore, within each
color type, feral pigeons display continuous variation in the amount of melanin
pigment present in the feathers, with individuals varying from pure white to a
full dark melanic color. Coloration is highly heritable and it has been suggested
that it is under natural or sexual selection, or both. Our objective was to investigate
whether MC1R allelic variants are associated with plumage color in feral pigeons.
Findings. We sequenced 888 bp of the coding sequence of MC1R among pigeons varying
both in the type, eumelanin or pheomelanin, and the amount of melanin in their
feathers. We detected 10 non-synonymous substitutions and 2 synonymous substitution
but none of them were associated with a plumage type. It remains possible that
non-synonymous substitutions that influence coloration are present in the short
MC1R fragment that we did not sequence but this seems unlikely because we analyzed
the entire functionally important region of the gene. Conclusions: Our results
show that color differences among feral pigeons are probably not attributable
to amino acid variation at the MC1R locus. Therefore, variation in regulatory
regions of MC1R or variation in other genes may be responsible for the color polymorphism
of feral pigeons.'

text: Understanding fitness landscapes, a conceptual depiction of the genotype-to-phenotype
relationship, is crucial to many areas of biology. Two aspects of fitness landscapes
are the focus of contemporary studies of molecular evolution. First, the local
shape of the fitness landscape defined by the contribution of individual alleles
to fitness that is independent of all genetic interactions. Second, the global,
multidimensional fitness landscape shape determined by how interactions between
alleles at different loci change each other’s fitness impact, or epistasis. In
explaining the high amino-acid usage (u), we focused on the global shape of the
fitness landscape, ignoring the perturbations at individual sites.

text: A survey of avifauna was carried out in the Mys Shmidta area, north Chukotka,
Russia from 8 June to 12 July 2011. A total of 90 species was recorded in the
area, which together with literature data made a final list of 104 species. For
several species this area is beyond the northern, north-eastern or north-western
limits of their known distribution. We collected new data for 19 globally or locally
threatened species. Tundra Swan Cygnus columbianus, Emperor Goose Anser canagica,
American Golden Plover Pluvialis dominica, Western Sandpiper Calidris mauri, Semipalmated
Sandpiper C. pusilla, Northern House Martin Delichon urbica and Barn Swallow Hirundo
rustica were all confirmed to be breeding. Breeding of Brent Goose Branta bernicla
nigricans, Spectacled Eider Somateria fischeri and Steller's Eider Polysticta
stelleri was judged to be 'very likely'. There was no evidence for breeding of
Ross's Gull Rhodostethia rosea despite several records. Two Eurasian Dotterels
Eudromias morinellus were recorded displaying for the first time in the area,
but the status of the species is unclear. The area is important for Snowy Owl
Nyctea scandiaca, and as moulting grounds for Emperor Goose. Canada Goose Branta
canadensis, Baikal Teal Anas formosa, Bar-tailed Godwit Limosa lapponica, Slaty-backed
Gull Larus schistisagus, Thayer's Gull L. thayeri, Black-headed Gull L. ridibundus,
White-tailed Eagle Haliaeetus albicilla, Steller's Sea Eagle H. pelagicus, Osprey
Pandion haliaetus, Arctic Warbler Phylloscopus borealis and House Sparrow Passer
domesticus are more likely to be rare vagrants or migrants. An observation of
a Pine Siskin Carduelis pinus is the first record for Eurasia.

text: Spontaneous formation of colonies of bacteria or flocks of birds are examples
of self-organization in active living matter. Here, we demonstrate a form of self-organization
from nonequilibrium driving forces in a suspension of synthetic photoactivated
colloidal particles. They lead to two-dimensional "living crystals," which form,
break, explode, and re-form elsewhere. The dynamic assembly results from a competition
between self-propulsion of particles and an attractive interaction induced respectively
by osmotic and phoretic effects and activated by light. We measured a transition
from normal to giant-number fluctuations. Our experiments are quantitatively described
by simple numerical simulations. We show that the existence of the living crystals
is intrinsically related to the out-of-equilibrium collisions of the self-propelled
particles.

text: Internal tide driven mixing plays a key role in sustaining the deep ocean
stratification and meridional overturning circulation. Internal tides can be generated
by topographic horizontal scales ranging from hundreds of meters to tens of kilometers.
State of the art topographic products barely resolve scales smaller than ∼10 km
in the deep ocean. On these scales abyssal hills dominate ocean floor roughness.
The impact of abyssal hill roughness on internal‐tide generation is evaluated
in this study. The conversion of M2 barotropic to baroclinic tidal energy is calculated
based on linear wave theory both in real and spectral space using the Shuttle
Radar Topography Mission SRTM30_PLUS bathymetric product at 1/120° resolution
with and without the addition of synthetic abyssal hill roughness. Internal tide
generation by abyssal hills integrates to 0.1 TW globally or 0.03 TW when the
energy flux is empirically corrected for supercritical slope (i.e., ∼10% of the
energy flux due to larger topographic scales resolved in standard products in
both cases). The abyssal hill driven energy conversion is dominated by mid‐ocean
ridges, where abyssal hill roughness is large. Focusing on two regions located
over the Mid‐Atlantic Ridge and the East Pacific Rise, it is shown that regionally
linear theory predicts an increase of the energy flux due to abyssal hills of
up to 100% or 60% when an empirical correction for supercritical slopes is attempted.
Therefore, abyssal hills, unresolved in state of the art topographic products,
can have a strong impact on internal tide generation, especially over mid‐ocean
ridges.

text: "In this study the response of tropical precipitation extremes to warming
in organized convection is examined using a cloud-resolving model. Vertical shear
is imposed to organize the convection into squall lines. Earlier studies show
that in disorganized convection, the fractional increase of precipitation extremes
is similar to that of surface water vapor, which is substantially smaller than
the increase in column water vapor. It has been suggested that organized convection
could lead to stronger amplifications.\r\nRegardless of the strength of the shear,
amplifications of precipitation extremes in the cloud-resolving simulations are
comparable to those of surface water vapor and are substantially less than increases
in column water vapor. The results without shear and with critical shear, for
which the squall lines are perpendicular to the shear, are surprisingly similar
with a fractional rate of increase of precipitation extremes slightly smaller
than that of surface water vapor. Interestingly, the dependence on shear is nonmonotonic,
and stronger supercritical shear yields larger rates, close to or slightly larger
than surface humidity.\r\nA scaling is used to evaluate the thermodynamic and
dynamic contributions to precipitation extreme changes. To first order, they are
dominated by the thermodynamic component, which has the same magnitude for all
shears, close to the change in surface water vapor. The dynamic contribution plays
a secondary role and tends to weaken extremes without shear and with critical
shear, while it strengthens extremes with supercritical shear. These different
dynamic contributions for different shears are due to different responses of convective
mass fluxes in individual updrafts to warming."

text: We introduce a self-propelled colloidal hematite docker that can be steered
to a small particle cargo many times its size, dock, transport the cargo to a
remote location, and then release it. The self-propulsion and docking are reversible
and activated by visible light. The docker can be steered either by a weak uniform
magnetic field or by nanoscale tracks in a textured substrate. The light-activated
motion and docking originate from osmotic/phoretic particle transport in a concentration
gradient of fuel, hydrogen peroxide, induced by the photocatalytic activity of
the hematite. The docking mechanism is versatile and can be applied to various
materials and shapes. The hematite dockers are simple single-component particles
and are synthesized in bulk quantities. This system opens up new possibilities
for designing complex micrometer-size factories as well as new biomimetic systems.

text: Recent experiments have shown that spreading epithelial sheets exhibit a long-range
coordination of motility forces that leads to a buildup of tension in the tissue,
which may enhance cell division and the speed of wound healing. Furthermore, the
edges of these epithelial sheets commonly show finger-like protrusions whereas
the bulk often displays spontaneous swirls of motile cells. To explain these experimental
observations, we propose a simple flocking-type mechanism, in which cells tend
to align their motility forceswith their velocity. Implementing this idea in amechanical
tissue simulation, the proposed model gives rise to efficient spreading and can
explain the experimentally observed long-range alignment of motility forces in
highly disordered patterns, as well as the buildup of tensile stress throughout
the tissue. Our model also qualitatively reproduces the dependence of swirl size
and swirl velocity on cell density reported in experiments and exhibits an undulation
instability at the edge of the spreading tissue commonly observed in vivo. Finally,
we study the dependence of colony spreading speed on important physical and biological
parameters and derive simple scaling relations that show that coordination of
motility forces leads to an improvement of the wound healing process for realistic
tissue parameters.

text: Nucleosome remodelers of the DDM1/Lsh family are required for DNA methylation
of transposable elements, but the reason for this is unknown. How DDM1 interacts
with other methylation pathways, such as small-RNA-directed DNA methylation (RdDM),
which is thought to mediate plant asymmetric methylation through DRM enzymes,
is also unclear. Here, we show that most asymmetric methylation is facilitated
by DDM1 and mediated by the methyltransferase CMT2 separately from RdDM. We find
that heterochromatic sequences preferentially require DDM1 for DNA methylation
and that this preference depends on linker histone H1. RdDM is instead inhibited
by heterochromatin and absolutely requires the nucleosome remodeler DRD1. Together,
DDM1 and RdDM mediate nearly all transposon methylation and collaborate to repress
transposition and regulate the methylation and expression of genes. Our results
indicate that DDM1 provides DNA methyltransferases access to H1-containing heterochromatin
to allow stable silencing of transposable elements in cooperation with the RdDM
pathway.

text: Arabidopsis thaliana endosperm, a transient tissue that nourishes the embryo,
exhibits extensive localized DNA demethylation on maternally inherited chromosomes.
Demethylation mediates parent-of-origin–specific (imprinted) gene expression but
is apparently unnecessary for the extensive accumulation of maternally biased
small RNA (sRNA) molecules detected in seeds. Endosperm DNA in the distantly related
monocots rice and maize is likewise locally hypomethylated, but whether this hypomethylation
is generally parent-of-origin specific is unknown. Imprinted expression of sRNA
also remains uninvestigated in monocot seeds. Here, we report high-coverage sequencing
of the Kitaake rice cultivar that enabled us to show that localized hypomethylation
in rice endosperm occurs solely on the maternal genome, preferring regions of
high DNA accessibility. Maternally expressed imprinted genes are enriched for
hypomethylation at putative promoter regions and transcriptional termini and paternally
expressed genes at promoters and gene bodies, mirroring our recent results in
A. thaliana. However, unlike in A. thaliana, rice endosperm sRNA populations are
dominated by specific strong sRNA-producing loci, and imprinted 24-nt sRNAs are
expressed from both parental genomes and correlate with hypomethylation. Overlaps
between imprinted sRNA loci and imprinted genes expressed from opposite alleles
suggest that sRNAs may regulate genomic imprinting. Whereas sRNAs in seedling
tissues primarily originate from small class II (cut-and-paste) transposable elements,
those in endosperm are more uniformly derived, including sequences from other
transposon classes, as well as genic and intergenic regions. Our data indicate
that the endosperm exhibits a unique pattern of sRNA expression and suggest that
localized hypomethylation of maternal endosperm DNA is conserved in flowering
plants.
