text: Channelrhodopsin-2 (ChR2), one of the archea-type rhodopsins from green algae,
is a potentially useful optogenetic tool for restoring vision in patients with
photoreceptor degeneration, such as retinitis pigmentosa. If the ChR2 gene is
transferred to retinal ganglion cells (RGCs), which send visual information to
the brain, the RGCs may be repurposed to act as photoreceptors. In this study,
by using a transgenic rat expressing ChR2 specifically in the RGCs under the regulation
of a Thy-1.2 promoter, we tested the possibility that direct photoactivation of
RGCs could restore effective vision. Although the contrast sensitivities of the
optomotor responses of transgenic rats were similar to those observed in the wild-type
rats, they were enhanced for visual stimuli of low-spatial frequency after the
degeneration of native photoreceptors. This result suggests that the visual signals
derived from the ChR2-expressing RGCs were reinterpreted by the brain to form
behavior-related vision.

text: 'We consider N×N Hermitian random matrices with i.i.d. entries. The matrix
is normalized so that the average spacing between consecutive eigenvalues is of
order 1/N. We study the connection between eigenvalue statistics on microscopic
energy scales η≪1 and (de)localization properties of the eigenvectors. Under suitable
assumptions on the distribution of the single matrix elements, we first give an
upper bound on the density of states on short energy scales of order η∼log N/N.
We then prove that the density of states concentrates around the Wigner semicircle
law on energy scales η≫N−2/3. We show that most eigenvectors are fully delocalized
in the sense that their ℓp-norms are comparable with N1/p−1/2 for p≥2, and we
obtain the weaker bound N2/3(1/p−1/2) for all eigenvectors whose eigenvalues are
separated away from the spectral edges. We also prove that, with a probability
very close to one, no eigenvector can be localized. Finally, we give an optimal
bound on the second moment of the Green function. '

text: We propose a new approach for the study of the time evolution of a factorized
N-particle bosonic wave function with respect to a mean-field dynamics with a
bounded interaction potential. The new technique, which is based on the control
of the growth of the correlations among the particles, leads to quantitative bounds
on the difference between the many-particle Schrödinger dynamics and the one-particle
nonlinear Hartree dynamics. In particular the one-particle density matrix associated
with the solution to the N-particle Schrödinger equation is shown to converge
to the projection onto the one-dimensional sub-space spanned by the solution to
the Hartree equation with a speed of convergence of order 1/N for all fixed times.

text: We consider N × N Hermitian random matrices with independent identical distributed
entries. The matrix is normalized so that the average spacing between consecutive
eigenvalues is of order 1/N. Under suitable assumptions on the distribution of
the single matrix element, we prove that, away from the spectral edges, the density
of eigenvalues concentrates around the Wigner semicircle law on energy scales
n ≫ N -1 (log N) 8 . Up to the logarithmic factor, this is the smallest energy
scale for which the semicircle law may be valid. We also prove that for all eigenvalues
away from the spectral edges, the -tempℓ∞-norm of the corresponding eigenvectors
is of order O(N -1/2), modulo logarithmic corrections. The upper bound O(N -1/2)
implies that every eigenvector is completely delocalized, i.e., the maximum size
of the components of the eigenvector is of the same order as their average size.
In the Appendix, we include a lemma by J. Bourgain which removes one of our assumptions
on the distribution of the matrix elements.

text: We consider the evolution of N bosons interacting with a repulsive short range
pair potential in three dimensions. The potential is scaled according to the Gross-Pitaevskii
scaling, i.e. it is given by N 2 V(N(x i - x j )). We monitor the behaviour of
the solution to the N-particle Schrödinger equation in a spatial window where
two particles are close to each other. We prove that within this window a short-scale
interparticle structure emerges dynamically. The local correlation between the
particles is given by the two-body zero energy scattering mode. This is the characteristic
structure that was expected to form within a very short initial time layer and
to persist for all later times, on the basis of the validity of the Gross-Pitaevskii
equation for the evolution of the Bose-Einstein condensate. The zero energy scattering
mode emerges after an initial time layer where all higher energy modes disperse
out of the spatial window. We can prove the persistence of this structure up to
sufficiently small times before three-particle correlations could develop.

text: As reported in a number of recent studies, turbulence in pipe flow is transient
for Re<2000 and the flow eventually always returns to the laminar state. Generally,
the lifetime of turbulence has been observed to increase rapidly with Reynolds
number but there is currently no accord on the exact scaling behaviour. In particular,
it is not clear whether a critical point exists where turbulence becomes sustained
or if it remains transient. We here aim to clarify if these conflicting results
may have been caused by the different experimental and numerical protocols used
to trigger turbulence in these studies.

text: In pipe flow at low Reynolds number, decay of localized disturbances is observed.
As the Reynolds number is increased, the question emerges whether the life time
of these disturbances diverges at a finite Reynolds number or remains transient.
In the current investigation we determine their life time quantitatively from
pressure measurements, while in previous investigations the distance over which
a structure survives has been determined. The obtained results confirm that the
life time of localized disturbances does not diverge in the range of Reynolds
numbers covered in the current experiment.

Plants exhibit an amazing developmental flexibility. Plant embryogenesis results in the establishment of a simple apical-basal axis represented by apical shoot and basal root meristems. Later, during postembryonic growth, shaping of the plant body continues by the formation and activation of numerous adjacent meristems that give rise to lateral shoot branches, leaves, flowers, or lateral roots. This developmental plasticity reflects an important feature of the plant's life strategy based on the rapid reaction to different environmental stimuli, such as temperature fluctuations, availability of nutrients, light or water and response resulting in modulation of developmental programs. Plant hormones are important endogenous factors for the integration of these environmental inputs and regulation of plant development. After a period of studies focused primarily on single hormonal pathways that enabled us to understand the hormone perception and signal transduction mechanisms, it became obvious that the developmental output mediated by a single hormonal pathway is largely modified through a whole network of interactions with other hormonal pathways. In this review, we will summarize recent knowledge on hormonal networks that regulate the development and growth of root with focus on the hormonal interactions that shape the root apical meristem.

text: Lateral root formation is a major determinant of root systems architecture.
The degree of root branching impacts the efficiency of water uptake, acquisition
of nutrients and anchorage by plants. Understanding the regulation of lateral
root development is therefore of vital agronomic importance. The molecular and
cellular basis of lateral root formation has been most extensively studied in
the plant model Arabidopsis thaliana (Arabidopsis). Significant progress has recently
been made in identifying many new Arabidopsis genes that regulate lateral root
initiation, patterning and emergence processes. We review how these studies have
revealed that the plant hormone auxin represents a common signal that integrates
these distinct yet interconnected developmental processes.

We describe a new implementation of the Edmonds’s algorithm for computing a perfect matching of minimum cost, to which we refer as Blossom V. A key feature of our implementation is a combination of two ideas that were shown to be effective for this problem: the “variable dual updates” approach of Cook and Rohe (INFORMS J Comput 11(2):138–148, 1999) and the use of priority queues. We achieve this by maintaining an auxiliary graph whose nodes correspond to alternating trees in the Edmonds’s algorithm. While our use of priority queues does not improve the worst-case complexity, it appears to lead to an efficient technique. In the majority of our tests Blossom V outperformed previous implementations of Cook and Rohe (INFORMS J Comput 11(2):138–148, 1999) and Mehlhorn and Schäfer (J Algorithmics Exp (JEA) 7:4, 2002), sometimes by an order of magnitude. We also show that for large VLSI instances it is beneficial to update duals by solving a linear program, contrary to a conjecture by Cook and Rohe.

text: Plant-parasitic nematodes are destructive plant pathogens that cause significant
yield losses. They induce highly specialized feeding sites (NFS) in infected plant
roots from which they withdraw nutrients. In order to establish these NFS, it
is thought that the nematodes manipulate the molecular and physiological pathways
of their hosts. Evidence is accumulating that the plant signalling molecule auxin
is involved in the initiation and development of the feeding sites of sedentary
plant-parasitic nematodes. Intercellular transport of auxin is essential for various
aspects of plant growth and development. Here, we analysed the spatial and temporal
expression of PIN auxin transporters during the early events of NFS establishment
using promoter-GUS/GFP fusion lines. Additionally, single and double pin mutants
were used in infection studies to analyse the role of the different PIN proteins
during cyst nematode infection. Based on our results, we postulate a model in
which PIN1-mediated auxin transport is needed to deliver auxin to the initial
syncytial cell, whereas PIN3 and PIN4 distribute the accumulated auxin laterally
and are involved in the radial expansion of the NFS. Our data demonstrate that
cyst nematodes are able to hijack the auxin distribution network in order to facilitate
the infection process. © 2009 Grunewald et al

text: "\n\nAuxin transport is mediated at the cellular level by three independent
mechanisms that are characterised by the PIN-formed (PIN), P-glycoprotein (ABCB/PGP)
and AUX/LAX transport proteins. The PIN and ABCB transport proteins, best represented
by PIN1 and ABCB19 (PGP19), have been shown to coordinately regulate auxin efflux.
When PIN1 and ABCB19 coincide on the plasma membrane, their interaction enhances
the rate and specificity of auxin efflux and the dynamic cycling of PIN1 is reduced.
However, ABCB19 function is not regulated by the dynamic cellular trafficking
mechanisms that regulate PIN1 in apical tissues, as localisation of ABCB19 on
the plasma membrane was not inhibited by short-term treatments with latrunculin
B, oryzalin, brefeldin A (BFA) or wortmannin - all of which have been shown to
alter PIN1 and/or PIN2 plasma membrane localisation. When taken up by endocytosis,
the styryl dye FM4-64 labels diffuse rather than punctuate intracellular bodies
in abcb19 (pgp19), and some aggregations of PIN1 induced by short-term BFA treatment
did not disperse after BFA washout in abcb19. Although the subcellular localisations
of ABCB19 and PIN1 in the reciprocal mutant backgrounds were like those in wild
type, PIN1 plasma membrane localisation in abcb19 roots was more easily perturbed
by the detergent Triton X-100, but not other non-ionic detergents. ABCB19 is stably
associated with sterol/sphingolipid-enriched membrane fractions containing BIG/TIR3
and partitions into Triton X-100 detergent-resistant membrane (DRM) fractions.
In the wild type, PIN1 was also present in DRMs, but was less abundant in abcb19
DRMs. These observations suggested a rationale for the observed lack of auxin
transport activity when PIN1 is expressed in a non-plant heterologous system.
PIN1 was therefore expressed in Schizosaccharomyces pombe, which has plant-like
sterol-enriched microdomains, and catalysed auxin transport in these cells. These
data suggest that ABCB19 stabilises PIN1 localisation at the plasma membrane in
discrete cellular subdomains where PIN1 and ABCB19 expression overlaps. "

text: Endocytic vesicle trafficking is crucial for regulating activity and localization
of plasma membrane components, but the process is still poorly genetically defined
in plants. Membrane proteins of the PIN-FORMED (PIN) family exhibit polar localization
in plant cells and facilitate cellular efflux of the plant hormone auxin, thereby
regulating multiple developmental processes [1, 2]. PIN proteins undergo constitutive
endocytosis and GNOM ARF GEF-dependent recycling [3-5], and their localization
is under extensive regulation by developmental and environmental cues [6-9]. We
designed a fluorescence imaging-based screen to identify Arabidopsis thaliana
mutants defective in internalization of proteins including PINs from the plasma
membrane. We identified three mutant loci, BFA-visualized endocytic trafficking
defective1 (ben1) through ben3 that do not efficiently accumulate PIN1-GFP in
intracellular compartments after inhibition of recycling and secretion by fungal
toxin brefeldin A (BFA). Fine mapping revealed that BEN1 encodes an ARF GEF vesicle
trafficking regulator from the functionally uncharacterized BIG class. ben1 mutant
has been previously implicated in pathogen response [10] and shows cell polarity,
BFA sensitivity, and growth defects. BEN1 is involved in endocytosis of plasma
membrane proteins and localizes to early endocytic compartments distinct from
GNOM-positive endosomes. Our results identify BEN1 as the ARF GEF mediating early
endosomal traffic.

text: Postembryonic de novo organogenesis represents an important competence evolved
in plants that allows their physiological and developmental adaptation to changing
environmental conditions. The phytohormones auxin and cytokinin (CK) are important
regulators of the developmental fate of pluripotent plant cells. However, the
molecular nature of their interaction(s) in control of plant organogenesis is
largely unknown. Here, we show that CK modulates auxin-induced organogenesis (AIO)
via regulation of the efflux-dependent intercellular auxin distribution. We used
the hypocotyl explants-based in vitro system to study the mechanism underlying
de novo organogenesis. We show that auxin, but not CK, is capable of triggering
organogenesis in hypocotyl explants. The AIO is accompanied by endogenous CK production
and tissue-specific activation of CK signaling. CK affects differential auxin
distribution, and the CK-mediated modulation of organogenesis is simulated by
inhibition of polar auxin transport. CK reduces auxin efflux from cultured tobacco
cells and regulates expression of auxin efflux carriers from the PIN family in
hypocotyl explants. Moreover, endogenous CK levels influence PIN transcription
and are necessary to maintain intercellular auxin distribution in planta. Based
on these findings, we propose a model in which auxin acts as a trigger of the
organogenic processes, whose output is modulated by the endogenously produced
CKs. We propose that an important mechanism of this CK action is its effect on
auxin distribution via regulation of expression of auxin efflux carriers.

text: 'Plant development is governed by signaling molecules called phytohormones.
Typically, in certain developmental processes more than 1 hormone is implicated
and, thus, coordination of their overlapping activities is crucial for correct
plant development. However, molecular mechanisms underlying the hormonal crosstalk
are only poorly understood. Multiple hormones including cytokinin and auxin have
been implicated in the regulation of root development. Here we dissect the roles
of cytokinin in modulating growth of the primary root. We show that cytokinin
effect on root elongation occurs through ethylene signaling whereas cytokinin
effect on the root meristem size involves ethylene-independent modulation of transport-dependent
asymmetric auxin distribution. Exogenous or endogenous modification of cytokinin
levels and cytokinin signaling lead to specific changes in transcription of several
auxin efflux carrier genes from the PIN family having a direct impact on auxin
efflux from cultured cells and on auxin distribution in the root apex. We propose
a novel model for cytokinin action in regulating root growth: Cytokinin influences
cell-to-cell auxin transport by modification of expression of several auxin transport
components and thus modulates auxin distribution important for regulation of activity
and size of the root meristem.'

text: The dynamic, differential distribution of the hormone auxin within plant tissues
controls an impressive variety of developmental processes, which tailor plant
growth and morphology to environmental conditions. Various environmental and endogenous
signals can be integrated into changes in auxin distribution through their effects
on local auxin biosynthesis and intercellular auxin transport. Individual cells
interpret auxin largely by a nuclear signaling pathway that involves the F box
protein TIR1 acting as an auxin receptor. Auxin-dependent TIR1 activity leads
to ubiquitination-based degradation of transcriptional repressors and complex
transcriptional reprogramming. Thus, auxin appears to be a versatile trigger of
preprogrammed developmental changes in plant cells.

text: As multicellular organisms, plants, like animals, use endogenous signaling
molecules to coordinate their own physiology and development. To compensate for
the absence of a cardiovascular system, plants have evolved specialized transport
pathways to distribute signals and nutrients. The main transport streams include
the xylem flow of the nutrients from the root to the shoot and the phloem flow
of materials from the photosynthetic active tissues. These long-distance transport
processes are complemented by several intercellular transport mechanisms (apoplastic,
symplastic and transcellular transport). A prominent example of transcellular
flow is transport of the phytohormone auxin within tissues. The process is mediated
by influx and efflux carriers, whose polar localization in the plasma membrane
determines the directionality of the flow. This polar auxin transport generates
auxin maxima and gradients within tissues that are instrumental in the diverse
regulation of various plant developmental processes, including embryogenesis,
organogenesis, vascular tissue formation and tropisms.
