We review our proof that in a scaling limit, the time evolution of a quantum particle in a static random environment leads to a diffusion equation. In particular, we discuss the role of Feynman graph expansions and of renormalization.

We consider random Schrödinger equations on R d for d ≽ 3 with a homogeneous Anderson–Poisson type random potential. Denote by λ the coupling constant and ψt the solution with initial data ψ0 . The space and time variables scale as x∼λ−2−ϰ/2 and t∼λ−2−ϰ with 0<ϰ<ϰ0(d) . We prove that, in the limit λ → 0, the expectation of the Wigner distribution of ψt converges weakly to the solution of a heat equation in the space variable x for arbitrary L 2 initial data.
The proof is based on analyzing the phase cancellations of multiple scatterings on the random potential by expanding the propagator into a sum of Feynman graphs. In this paper we consider the non-recollision graphs and prove that the amplitude of the non-ladder diagrams is smaller than their “naive size” by an extra λ c factor per non-(anti)ladder vertex for some c > 0. This is the first rigorous result showing that the improvement over the naive estimates on the Feynman graphs grows as a power of the small parameter with the exponent depending linearly on the number of vertices. This estimate allows us to prove the convergence of the perturbation series.

text: We study the dynamics of an electron weakly coupled to a phonon gas. The initial
state of the electron is the superposition of two spatially localized distant
bumps moving towards each other, and the phonons are in a thermal state. We investigate
the dynamics of the system in the kinetic regime and show that the time evolution
makes the non-diagonal terms of the density matrix of the electron decay, destroying
the interference between the two bumps. We show that such a damping effect is
exponential in time, and the related decay rate is proportional to the total scattering
cross section of the electron-phonon interaction.

text: Consider N bosons in a finite box Λ= [0,L]3⊂ R3 interacting via a two-body
non-negative soft potential V=λ V with V fixed and λ>0 small. We will take
the limit L,N→∞ by keeping the density =N/L3 fixed and small. We construct a variational
state, which gives an upper bound on the ground-state energy per particle ε, ε≤4πa
[1+ (128/15π) (a3) 1/2 Sλ] +O (2 ln ), as →0, with a constant satisfying 1≤ Sλ
≤1+Cλ. Here a is the scattering length of V and thus depends on λ. In comparison,
the prediction by Lee and Yang [Phys. Rev. 105, 1119 (1957)] and Lee, Huang, and
Yang [Phys. Rev. 106, 1135 (1957)] asserts that Sλ =1 independent of λ.

text: The collapse of turbulence, observable in shear flows at low Reynolds numbers,
raises the question if turbulence is generically of a transient nature or becomes
sustained at some critical point. Recent data have led to conflicting views with
the majority of studies supporting the model of turbulence turning into an attracting
state. Here we present lifetime measurements of turbulence in pipe flow spanning
8 orders of magnitude in time, drastically extending all previous investigations.
We show that no critical point exists in this regime and that in contrast to the
prevailing view the turbulent state remains transient. To our knowledge this is
the first observation of superexponential transients in turbulence, confirming
a conjecture derived from low-dimensional systems.

text: Telomeres in many eukaryotes are maintained by telomerase in whose absence
telomere shortening occurs. However, telomerase-deficient Arabidopsis thaliana
mutants (Attert -/-) show extremely low rates of telomere shortening per plant
generation (250-500 bp), which does not correspond to the expected outcome of
replicative telomere shortening resulting from ca. 1,000 meristem cell divisions
per seed-to-seed generation. To investigate the influence of the number of cell
divisions per seed-to-seed generation, Attert -/- mutant plants were propagated
from seeds coming either from the lower-most or the upper-most siliques (L- and
U-plants) and the length of their telomeres were followed over several generations.
The rate of telomere shortening was faster in U-plants, than in L-plants, as would
be expected from their higher number of cell divisions per generation. However,
this trend was observed only in telomeres whose initial length is relatively high
and the differences decreased with progressive general telomere shortening over
generations. But in generation 4, the L-plants frequently show a net telomere
elongation, while the U-plants fail to do so. We propose that this is due to the
activation of alternative telomere lengthening (ALT), a process which is activated
in early embryonic development in both U- and L-plants, but is overridden in U-plants
due to their higher number of cell divisions per generation. These data demonstrate
what so far has only been speculated, that in the absence of telomerase, the number
of cell divisions within one generation influences the control of telomere lengths.
These results also reveal a fast and efficient activation of ALT mechanism(s)
in response to the loss of telomerase activity and imply that ALT is probably
involved also in normal plant development.

text: Many aspects of plant development, including patterning and tropisms, are
largely dependent on the asymmetric distribution of the plant signaling molecule
auxin. Auxin transport inhibitors (ATIs), which interfere with directional auxin
transport, have been essential tools in formulating this concept. However, despite
the use of ATIs in plant research for many decades, the mechanism of ATI action
has remained largely elusive. Using real-time live-cell microscopy, we show here
that prominent ATIs such as 2,3,5-triiodobenzoic acid (TIBA) and 2-(1-pyrenoyl)
benzoic acid (PBA) inhibit vesicle trafficking in plant, yeast, and mammalian
cells. Effects on micropinocytosis, rab5-labeled endosomal motility at the periphery
of HeLa cells and on fibroblast mobility indicate that ATIs influence actin cytoskeleton.
Visualization of actin cytoskeleton dynamics in plants, yeast, and mammalian cells
show that ATIs stabilize actin. Conversely, stabilizing actin by chemical or genetic
means interferes with endocytosis, vesicle motility, auxin transport, and plant
development, including auxin transport-dependent processes. Our results show that
a class of ATIs act as actin stabilizers and advocate that actin-dependent trafficking
of auxin transport components participates in the mechanism of auxin transport.
These studies also provide an example of how the common eukaryotic process of
actin-based vesicle motility can fulfill a plant-specific physiological role.

Cell polarity manifested by the polar cargo delivery to different plasma-membrane domains is a fundamental feature of multicellular organisms. Pathways for polar delivery have been identified in animals; prominent among them is transcytosis, which involves cargo movement between different sides of the cell [1]. PIN transporters are prominent polar cargoes in plants, whose polar subcellular localization determines the directional flow of the signaling molecule auxin [2, 3]. In this study, we address the cellular mechanisms of PIN polar targeting and dynamic polarity changes. We show that apical and basal PIN targeting pathways are interconnected but molecularly distinct by means of ARF GEF vesicle-trafficking regulators. Pharmacological or genetic interference with the Arabidopsis ARF GEF GNOM leads specifically to apicalization of basal cargoes such as PIN1. We visualize the translocation of PIN proteins between the opposite sides of polarized cells in vivo and show that this PIN transcytosis occurs by endocytic recycling and alternative recruitment of the same cargo molecules by apical and basal targeting machineries. Our data suggest that an ARF GEF-dependent transcytosis-like mechanism is operational in plants and provides a plausible mechanism to trigger changes in PIN polarity and hence auxin fluxes during embryogenesis and organogenesis.

Embryogenesis in Arabidopsis thaliana depends on the proper establishment and maintenance of local auxin accumulation. In the course of elucidating the connections between developmental progress and auxin distribution, several techniques have been developed to investigate spatial and temporal distribution of auxin response or accumulation in Arabidopsis embryos. This chapter reviews and describes two independent methods, the detection of the activity of auxin responsive transgenes and immunolocalization of auxin itself.

text: Embryogenesis of Arabidopsis thaliana follows a nearly invariant cell division
pattern and provides an ideal system for studies of early plant development. However,
experimental manipulation with embryogenesis is difficult, as the embryo develops
deeply inside maternal tissues. Here, we present a method to culture zygotic Arabidopsis
embryos in vitro. It enables culturing for prolonged periods of time from the
first developmental stages on. The technique omits excision of the embryo by culturing
the entire ovule, which facilitates the manual procedure. It allows pharmacological
manipulation of embryo development and does not interfere with standard techniques
for localizing gene expression and protein localization in the cultivated embryos.

text: Plants exhibit an exceptional adaptability to different environmental conditions.
To a large extent, this adaptability depends on their ability to initiate and
form new organs throughout their entire postembryonic life. Plant shoot and root
systems unceasingly branch and form axillary shoots or lateral roots, respectively.
The first event in the formation of a new organ is specification of founder cells.
Several plant hormones, prominent among them auxin, have been implicated in the
acquisition of founder cell identity by differentiated cells, but the mechanisms
underlying this process are largely elusive. Here, we show that auxin and its
local accumulation in root pericycle cells is a necessary and sufficient signal
to respecify these cells into lateral root founder cells. Analysis of the alf4-1
mutant suggests that specification of founder cells and the subsequent activation
of cell division leading to primordium formation represent two genetically separable
events. Time-lapse experiments show that the activation of an auxin response is
the earliest detectable event in founder cell specification. Accordingly, local
activation of auxin response correlates absolutely with the acquisition of founder
cell identity and precedes the actual formation of a lateral root primordium through
patterned cell division. Local production and subsequent accumulation of auxin
in single pericycle cells induced by Cre-Lox-based activation of auxin synthesis
converts them into founder cells. Thus, auxin is the local instructive signal
that is sufficient for acquisition of founder cell identity and can be considered
a morphogenetic trigger in postembryonic plant organogenesis.

text: Lateral roots originate deep within the parental root from a small number
of founder cells at the periphery of vascular tissues and must emerge through
intervening layers of tissues. We describe how the hormone auxin, which originates
from the developing lateral root, acts as a local inductive signal which re-programmes
adjacent cells. Auxin induces the expression of a previously uncharacterized auxin
influx carrier LAX3 in cortical and epidermal cells directly overlaying new primordia.
Increased LAX3 activity reinforces the auxin-dependent induction of a selection
of cell-wall-remodelling enzymes, which are likely to promote cell separation
in advance of developing lateral root primordia.

text: During the development of multicellular organisms, organogenesis and pattern
formation depend on formative divisions to specify and maintain pools of stem
cells. In higher plants, these activities are essential to shape the final root
architecture because the functioning of root apical meristems and the de novo
formation of lateral roots entirely rely on it. We used transcript profiling on
sorted pericycle cells undergoing lateral root initiation to identify the receptor-like
kinase ACR4 of Arabidopsis as a key factor both in promoting formative cell divisions
in the pericycle and in constraining the number of these divisions once organogenesis
has been started. In the root tip meristem, ACR4 shows a similar action by controlling
cell proliferation activity in the columella cell lineage. Thus, ACR4 function
reveals a common mechanism of formative cell division control in the main root
tip meristem and during lateral root initiation.

text: The polar, sub-cellular localization of PIN auxin efflux carriers determines
the direction of intercellular auxin flow, thus defining the spatial aspect of
auxin signalling. Dynamic, transcytosis-like relocalizations of PIN proteins occur
in response to external and internal signals, integrating these signals into changes
in auxin distribution. Here, we examine the cellular and molecular mechanisms
of polar PIN delivery and transcytosis. The mechanisms of the ARF-GEF-dependent
polar targeting and transcytosis are well conserved and show little variations
among diverse Arabidopsis ecotypes consistent with their fundamental importance
in regulating plant development. At the cellular level, we refine previous findings
on the role of the actin cytoskeleton in apical and basal PIN targeting, and identify
a previously unknown role for microtubules, specifically in basal targeting. PIN
protein delivery to different sides of the cell is mediated by ARF-dependent trafficking
with a previously unknown complex level of distinct ARF-GEF vesicle trafficking
regulators. Our data suggest that alternative recruitment of PIN proteins by these
distinct pathways can account for cell type- and cargo-specific aspects of polar
targeting, as well as for polarity changes in response to different signals. The
resulting dynamic PIN positioning to different sides of cells defines a three-dimensional
pattern of auxin fluxes within plant tissues.

text: The rate, polarity, and symmetry of the flow of the plant hormone auxin are
determined by the polar cellular localization of PIN-FORMED (PIN) auxin efflux
carriers. Flavonoids, a class of secondary plant metabolites, have been suspected
to modulate auxin transport and tropic responses. Nevertheless, the identity of
specific flavonoid compounds involved and their molecular function and targets
in vivo are essentially unknown. Here we show that the root elongation zone of
agravitropic pin2/eir1/wav6/agr1 has an altered pattern and amount of flavonol
glycosides. Application of nanomolar concentrations of flavonols to pin2 roots
is sufficient to partially restore root gravitropism. By employing a quantitative
cell biological approach, we demonstrate that flavonoids partially restore the
formation of lateral auxin gradients in the absence of PIN2. Chemical complementation
by flavonoids correlates with an asymmetric distribution of the PIN1 protein.
pin2 complementation probably does not result from inhibition of auxin efflux,
as supply of the auxin transport inhibitor N-1-naphthylphthalamic acid failed
to restore pin2 gravitropism. We propose that flavonoids promote asymmetric PIN
shifts during gravity stimulation, thus redirecting basipetal auxin streams necessary
for root bending. © 2008 by The American Society for Biochemistry and Molecular

text: All eukaryotic cells present at the cell surface a specific set of plasma
membrane proteins that modulate responses to internal and external cues and whose
activity is also regulated by protein degradation. We characterized the lytic
vacuole-dependent degradation of membrane proteins in Arabidopsis thaliana by
means of in vivo visualization of vacuolar targeting combined with quantitative
protein analysis. We show that the vacuolar targeting pathway is used by multiple
cargos including PIN-FORMED (PIN) efflux carriers for the phytohormone auxin.
In vivo visualization of PIN2 vacuolar targeting revealed its differential degradation
in response to environmental signals, such as gravity. In contrast to polar PIN
delivery to the basal plasma membrane, which depends on the vesicle trafficking
regulator ARF-GEF GNOM, PIN sorting to the lytic vacuolar pathway requires additional
brefeldin A-sensitive ARF-GEF activity. Furthermore, we identified putative retromer
components SORTING NEXIN1 (SNX1) and VACUOLAR PROTEIN SORTING29 (VPS29) as important
factors in this pathway and propose that the retromer complex acts to retrieve
PIN proteins from a late/pre-vacuolar compartment back to the recycling pathways.
Our data suggest that ARF GEF- and retromer-dependent processes regulate PIN sorting
to the vacuole in an antagonistic manner and illustrate instrumentalization of
this mechanism for fine-tuning the auxin fluxes during gravitropic response.

text: Plant development is characterized by a profound phenotypic plasticity that
often involves redefining of the developmental fate and polarity of cells within
differentiated tissues. The plant hormone auxin and its directional intercellular
transport play a major role in these processes because they provide positional
information and link cell polarity with tissue patterning. This plant-specific
mechanism of transport-dependent auxin gradients depends on subcellular dynamics
of auxin transport components, in particular on endocytic recycling and polar
targeting. Recent insights into these cellular processes in plants have revealed
important parallels to yeast and animal systems, including clathrin-dependent
endocytosis, retromer function, and transcytosis, but have also emphasized unique
features of plant cells such as diversity of polar targeting pathways; integration
of environmental signals into subcellular trafficking; and the link between endocytosis,
cell polarity, and cell fate specification. We review these advances and focus
on the translation of the subcellular dynamics to the regulation of whole-plant
development.
