text: Dark-grown dicotyledonous seedlings form a hook-like structure at the top
of the hypocotyl, which is controlled by the hormones auxin and ethylene. Hook
formation is dependent on an auxin signal gradient, whereas hook exaggeration
is part of the triple response provoked by ethylene in dark-grown Arabidopsis
seedlings. Several other hormones and light are also known to be involved in hook
development, but the molecular mechanisms that lead to the initial installation
of an auxin gradient are still poorly understood. In this study, we aimed to unravel
the cross-talk between auxin and ethylene in the apical hook. Auxin measurements,
the expression pattern of the auxin reporter DR5::GUS and the localization of
auxin biosynthesis enzymes and influx carriers collectively indicate the necessity
for auxin biosynthesis and efficient auxin translocation from the cotyledons and
meristem into the hypocotyl in order to support proper hook development. Auxin
accumulation in the meristem and cotyledons and in the hypocotyl is increased
∼2-fold upon treatment with ethylene. In addition, a strong ethylene signal leads
to enhanced auxin biosynthesis at the inner side of the hook. Finally, mutant
analysis demonstrates that the auxin influx carrier LAX3 is indispensable for
proper hook formation, whereas the auxin influx carrier AUX1 is involved in the
hook exaggeration phenotype induced by ethylene.

text: Unlike locomotive organisms capable of actively approaching essential resources,
sessile plants must efficiently exploit their habitat for water and nutrients.
This involves root-mediated underground interactions allowing plants to adapt
to soils of diverse qualities. The root system of plants is a dynamic structure
that modulates primary root growth and root branching by continuous integration
of environmental inputs, such as nutrition availability, soil aeration, humidity,
or salinity. Root branching is an extremely flexible means to rapidly adjust the
overall surface of the root system and plants have evolved efficient control mechanisms,
including, firstly initiation, when and where to start lateral root formation;
secondly lateral root primordia organogenesis, during which the development of
primordia can be arrested for a certain time; and thirdly lateral root emergence.
Our review will focus on the most recent advances in understanding the molecular
mechanisms involved in the regulation of lateral root initiation and organogenesis
with the main focus on root system of the model plant Arabidopsis thaliana.

text: Nitrate is both a nitrogen source for higher plants and a signal molecule
regulating their development. In Arabidopsis, the NRT1.1 nitrate transporter is
crucial for nitrate signaling governing root growth, and has been proposed to
act as a nitrate sensor. However, the sensing mechanism is unknown. Herein we
show that NRT1.1 not only transports nitrate but also facilitates uptake of the
phytohormone auxin. Moreover, nitrate inhibits NRT1.1-dependent auxin uptake,
suggesting that transduction of nitrate signal by NRT1.1 is associated with a
modification of auxin transport. Among other effects, auxin stimulates lateral
root development. Mutation of NRT1.1 enhances both auxin accumulation in lateral
roots and growth of these roots at low, but not high, nitrate concentration. Thus,
we propose that NRT1.1 represses lateral root growth at low nitrate availability
by promoting basipetal auxin transport out of these roots. This defines a mechanism
connecting nutrient and hormone signaling during organ development.

text: Toxin–antitoxin (TA) systems are commonly found on bacterial plasmids. The
antitoxin inhibits toxin activity unless the system is lost from the cell. Then
the shorter lived antitoxin degrades and the cell becomes susceptible to the toxin.
Selection for plasmid-encoded TA systems was initially thought to result from
their reducing the number of plasmid-free cells arising during growth in monoculture.
However, modelling and experiments have shown that this mechanism can only explain
the success of plasmid TA systems under a restricted set of conditions. Previously,
we have proposed and tested an alternative model explaining the success of plasmid
TA systems as a consequence of competition occurring between plasmids during co-infection
of bacterial hosts. Here, we test a further prediction of this model, that competition
between plasmids will lead to the biased accumulation of TA systems on plasmids
relative to chromosomes. Transposon-encoded TA systems were added to populations
of plasmid-containing cells, such that TA systems could insert into either plasmids
or chromosomes. These populations were enriched for transposon-containing cells
and then incubated in environments that did, or did not, allow effective within-host
plasmid competition to occur. Changes in the ratio of plasmid- to chromosome-encoded
TA systems were monitored. In agreement with our model, we found that plasmid-encoded
TA systems had a competitive advantage, but only when host cells were sensitive
to the effect of TA systems. This result demonstrates that within-host competition
between plasmids can select for TA systems.

Efficient zero-knowledge proofs of knowledge for group homomorphisms are essential for numerous systems in applied cryptography. Especially, Σ-protocols for proving knowledge of discrete logarithms in known and hidden order groups are of prime importance. Yet, while these proofs can be performed very efficiently within groups of known order, for hidden order groups the respective proofs are far less efficient.
This paper shows strong evidence that this efficiency gap cannot be bridged. Namely, while there are efficient protocols allowing a prover to cheat only with negligibly small probability in the case of known order groups, we provide strong evidence that for hidden order groups this probability is bounded below by 1/2 for all efficient Σ-protocols not using common reference strings or the like.
We prove our results for a comprehensive class of Σ-protocols in the generic group model, and further strengthen them by investigating certain instantiations in the plain model.

text: "Zero-knowledge proofs of knowledge (ZK-PoK) are important building blocks
for numerous cryptographic applications. Although ZK-PoK have a high potential
impact, their real world deployment is typically hindered by their significant
complexity compared to other (non-interactive) crypto primitives. Moreover, their
design and implementation are time-consuming and error-prone.\n\nWe contribute
to overcoming these challenges as follows: We present a comprehensive specification
language and a compiler for ZK-PoK protocols based on Σ-protocols. The compiler
allows the fully automatic translation of an abstract description of a proof goal
into an executable implementation. Moreover, the compiler overcomes various restrictions
of previous approaches, e.g., it supports the important class of exponentiation
homomorphisms with hidden-order co-domain, needed for privacy-preserving applications
such as DAA. Finally, our compiler is certifying, in the sense that it automatically
produces a formal proof of the soundness of the compiled protocol for a large
class of protocols using the Isabelle/HOL theorem prover. \n"

text: "Efficient zero-knowledge proofs of knowledge (ZK-PoK) are basic\n building
blocks of many practical cryptographic applications such as\n identification
schemes, group signatures, and secure multi-party\n computation (SMPC). Currently,
first applications that essentially\n rely on ZK-PoKs are being deployed in the
real world. The most\n prominent example is the Direct Anonymous Attestation
(DAA)\n protocol, which was adopted by the Trusted Computing Group (TCG) \n and
implemented as one of the functionalities of the cryptographic \n chip Trusted
Platform Module (TPM).\n\nImplementing systems using ZK-PoK turns out to be challenging,\n
\ since ZK-PoK are significantly more complex than standard crypto\n primitives
(e.g., encryption and signature schemes). As a result, \n the design-implementation
cycles of ZK-PoK are time-consuming\n and error-prone.\n\nTo overcome this, we
present a compiler with corresponding languages \n for the automatic generation
of sound and efficient ZK-PoK based on \n Σ-protocols. The protocol designer
using our compiler formulates \n the goal of a ZK-PoK proof in a high-level protocol
specification language,\n which abstracts away unnecessary technicalities from
the designer. The\n compiler then automatically generates the protocol implementation
in \n Java code; alternatively, the compiler can output a description of the
\n protocol in LaTeX which can be used for documentation or verification."

text: Development in multicellular organisms depends on the ability of individual
cells to coordinate their behavior by means of small signaling molecules to form
correctly patterned tissues. In plants, a unique mechanism of directional transport
of the signaling molecule auxin between cells connects cell polarity and tissue
patterning and thus is required for many aspects of plant development. Direction
of auxin flow is determined by polar subcellular localization of PIN auxin efflux
transporters. Dynamic PIN polar localization results from the constitutive endocytic
cycling to and from the plasma membrane, but it is not well understood how this
mechanism connects to regulators of cell polarity. The Rho family small GTPases
ROPs/RACs are master regulators of cell polarity, however their role in regulating
polar protein trafficking and polar auxin transport has not been established.
Here, by analysis of mutants and transgenic plants, we show that the ROP interactor
and polarity regulator scaffold protein ICR1 is required for recruitment of PIN
proteins to the polar domains at the plasma membrane. icr1 mutant embryos and
plants display an a array of severe developmental aberrations that are caused
by compromised differential auxin distribution. ICR1 functions at the plasma membrane
where it is required for exocytosis but does not recycle together with PINs. ICR1
expression is quickly induced by auxin but is suppressed at the positions of stable
auxin maxima in the hypophysis and later in the embryonic and mature root meristems.
Our results imply that ICR1 is part of an auxin regulated positive feedback loop
realized by a unique integration of auxin-dependent transcriptional regulation
into ROP-mediated modulation of cell polarity. Thus, ICR1 forms an auxin-modulated
link between cell polarity, exocytosis, and auxin transport-dependent tissue patterning.

text: The directional transport of the plant hormone auxin is a unique process mediating
a wide variety of developmental processes. Auxin movement between cells depends
on AUX1/LAX, PGP and PIN protein families that mediate auxin transport across
the plasma membrane. The directionality of auxin flow within tissues is largely
determined by polar, subcellular localization of PIN auxin efflux carriers. PIN
proteins undergo rapid subcellular dynamics that is important for the process
of auxin transport and its directionality. Furthermore, various environmental
and endogenous signals can modulate trafficking and polarity of PIN proteins and
by this mechanism change auxin distribution. Thus, the subcellular dynamics of
auxin transport proteins represents an important interface between cellular processes
and development of the whole plant. This review summarizes our recent contributions
to the field of PIN trafficking and auxin transport regulation. © 2009 Elsevier

text: The plant hormone auxin plays a crucial role in regulating plant development
and plant architecture. The directional auxin distribution within tissues depends
on PIN transporters that are polarly localized on the plasmamembrane. The PINpolarity
and the resulting auxin flow directionality aremediated by the antagonistic actions
of PINOID kinase and protein phosphatase 2A. However, the contributionof the PINphosphorylationto
the polar PINsortingis still unclear. Here, we identified an evolutionarily conserved
phosphorylation site within the central hydrophilic loop of PIN proteins that
is important for the apical and basal polar PIN localizations. Inactivation of
the phosphorylation site in PIN1(Ala) resulted in a predominantly basal targeting
and increased the auxinflowto the root tip. In contrast, the outcome of the phosphomimic
PIN1(Asp) manipulation was a constitutive, PINOID-independent apical targeting
of PIN1 and an increased auxin flow in the opposite direction. Furthermore, the
PIN1(Asp) functionally replaced PIN2 in its endogenous expression domain, revealing
that the phosphorylation-dependent polarity regulation contributes to functional
diversification within the PIN family. Our data suggest that PINOID-independent
PIN phosphorylation at one single site is adequate to change the PIN polarity
and, consequently, to redirect auxin fluxes between cells and provide the conceptual
possibility and means to manipulate auxin-dependent plant development and architecture.

text: The apical hook of dark-grown Arabidopsis seedlings is a simple structure
that develops soon after germination to protect the meristem tissues during emergence
through the soil and that opens upon exposure to light. Differential growth at
the apical hook proceeds in three sequential steps that are regulated by multiple
hormones, principally auxin and ethylene. We show that the progress of the apical
hook through these developmental phases depends on the dynamic, asymmetric distribution
of auxin, which is regulated by auxin efflux carriers of the PIN family. Several
PIN proteins exhibited specific, partially overlapping spatial and temporal expression
patterns, and their subcellular localization suggested auxin fluxes during hook
development. Genetic manipulation of individual PIN activities interfered with
different stages of hook development, implying that specific combinations of PIN
genes are required for progress of the apical hook through the developmental phases.
Furthermore, ethylene might modulate apical hook development by prolonging the
formation phase and strongly suppressing the maintenance phase. This ethylene
effect is in part mediated by regulation of PIN-dependent auxin efflux and auxin
signaling.

text: In animals, the interface between organism and environment is constituted
by the epithelium [1]. In plants, the exchange of nutrients and signals between
root and soil is crucial for their survival, but the cellular mechanisms underlying
the epithelium-like function and specific localization of proteins to the root
surface have not been identified [2]. Here we analyze the mechanism of polar delivery
to the root-soil interface of the proteins BOR4, ABCG37, and PEN3, which transport
nutrients [2], transport plant hormones, and are required for pathogen defense
[3], respectively. The simultaneous visualization of these proteins and the apical
and basal cargos in a single cell demonstrates that the outermost cell side represents
an additional polar domain. Delivery to this outer polar domain depends on ARF
GEF [4] and actin [5-8] function but does not require known molecular components
of the apical or basal targeting. The outer polar delivery is, in contrast to
known basal and apical cargos [9, 10], mediated by the polar secretion. Our findings
show that the outermost cell membranes of roots define an additional polar domain
in plant cells along with a specific, previously uncharacterized, polar targeting
mechanism that is important for defining the functional, epithelium-like root-soil
interface.

text: Remarkable progress in various techniques of in vivo fluorescence microscopy
has brought an urgent need for reliable markers for tracking cellular structures
and processes. The goal of this manuscript is to describe unexplored effects of
the FM (Fei Mao) styryl dyes, which are widely used probes that label processes
of endocytosis and vesicle trafficking in eukaryotic cells. Although there are
few reports on the effect of styryl dyes on membrane fluidity and the activity
of mammalian receptors, FM dyes have been considered as reliable tools for tracking
of plant endocytosis. Using plasma membrane-localized transporters for the plant
hormone auxin in tobacco BY-2 and Arabidopsis thaliana cell suspensions, we show
that routinely used concentrations of FM 4-64 and FM 5-95 trigger transient re-localization
of these proteins, and FM 1-43 affects their activity. The active process of re-localization
is blocked neither by inhibitors of endocytosis nor by cytoskeletal drugs. It
does not occur in A. thaliana roots and depends on the degree of hydrophobicity
(lipophilicity) of a particular FM dye. Our results emphasize the need for circumspection
during in vivo studies of membrane proteins performed using simultaneous labelling
with FM dyes.

text: Differential distribution of the plant hormone auxin within tissues mediates
a variety of developmental processes. Cellular auxin levels are determined by
metabolic processes including synthesis, degradation, and (de)conjugation, as
well as by auxin transport across the plasma membrane. Whereas transport of free
auxins such as naturally occurring indole-3-acetic acid (IAA) is well characterized,
little is known about the transport of auxin precursors and metabolites. Here,
we identify amutation in the ABCG37 gene of Arabidopsis that causes the polar
auxin transport inhibitor sensitive1 (pis1) phenotype manifested by hypersensitivity
to auxinic compounds. ABCG37 encodes the pleiotropic drug resistance transporter
that transports a range of synthetic auxinic compounds as well as the endogenous
auxin precursor indole-3-butyric acid (IBA), but not free IAA. ABCG37 and its
homolog ABCG36 act redundantly at outermost root plasma membranes and,unlike established
IAA transporters from the PIN and ABCB families, transport IBA out of the cells.
Our findings explore possible novel modes of regulating auxin homeostasis and
plant development by means of directional transport of the auxin precursor IBA
and presumably also other auxin metabolites.

text: The stem cell niche in the root meristem is critical for the development of
the plant root system. The plant hormone auxin acts as a versatile trigger in
many developmental processes, including the regulation of root growth, but its
role in the control of the stem cell activity remains largely unclear. Here we
show that local auxin levels, determined by biosynthesis and intercellular transport,
mediate maintenance or differentiation of distal stem cells in the Arabidopsis
thaliana roots. Genetic analysis shows that auxin acts upstream of the major regulators
of the stem cell activity, the homeodomain transcription factor WOX5, and the
AP-2 transcription factor PLETHORA. Auxin signaling for differentiation of distal
stem cells requires the transcriptional repressor IAA17/AXR3 as well as the ARF10
and ARF16 auxin response factors. ARF10 and ARF16 activities repress the WOX5
transcription and restrict it to the quiescent center, where WOX5, in turn, is
needed for the activity of PLETHORA. Our investigations reveal that long-distance
auxin signals act upstream of the short-range network of transcriptional factors
to mediate the differentiation of distal stem cells in roots.

text: Division of the Arabidopsis zygote defines two fundamentally different developmental
domains, the proembryo and suspensor. The resulting boundary separates domain-specific
gene expression, and a signal originating from the proembryo instructs the suspensor
to generate the root stem cell niche. While root induction is known to require
the phytohormone auxin and the Auxin Response Factor MONOPTEROS, it has remained
largely elusive how the two domains involved in this process are initially specified.
Here, we show that the GATA factor HANABA TARANU (HAN) is required to position
the inductive proembryo boundary. Mutations in HAN cause a coordinated apical
shift of gene expression patterns, revealing that HAN regulates transcription
in the basal proembryo. Key auxin transporters are affected as early as the 8
cell stage, resulting in apical redistribution of auxin. Remarkably, han embryos
eventually organize a root independent of MONOPTEROS and the suspensor around
a new boundary marked by the auxin maximum.

text: Plant vacuoles are essential multifunctional organelles largely distinct from
similar organelles in other eukaryotes. Embryo protein storage vacuoles and the
lytic vacuoles that perform a general degradation function are the best characterized,
but little is known about the biogenesis and transition between these vacuolar
types. Here, we designed a fluorescent marker- based forward genetic screen in
Arabidopsis thaliana and identified a protein affected trafficking2 (pat2) mutant,
whose lytic vacuoles display altered morphology and accumulation of proteins.
Unlike other mutants affecting the vacuole, pat2 is specifically defective in
the biogenesis, identity, and function of lytic vacuoles but shows normal sorting
of proteins to storage vacuoles. PAT2 encodes a putative β-subunit of adaptor
protein complex 3 (AP-3) that can partially complement the corresponding yeast
mutant. Manipulations of the putative AP-3 β adaptin functions suggest a plant-specific
role for the evolutionarily conserved AP-3 β in mediating lytic vacuole performance
and transition of storage into the lytic vacuoles independently of the main prevacuolar
compartment-based trafficking route.

text: Development of plants and their adaptive capacity towards ever‐changing environmental
conditions largely depend on the spatial distribution of the plant hormone auxin.
At the cellular level, various internal and external signals are translated into
specific changes in the polar, subcellular localization of auxin transporters
from the PIN family thereby directing and redirecting the intercellular fluxes
of auxin. The current model of polar targeting of PIN proteins towards different
plasma membrane domains encompasses apolar secretion of newly synthesized PINs
followed by endocytosis and recycling back to the plasma membrane in a polarized
manner. In this review, we follow the subcellular march of the PINs and highlight
the cellular and molecular mechanisms behind polar foraging and subcellular trafficking
pathways. Also, the entry points for different signals and regulations including
by auxin itself will be discussed within the context of morphological and developmental
consequences of polar targeting and subcellular trafficking.

text: Polar membrane cargo delivery is crucial for establishing cell polarity and
for directional transport processes. In plants, polar trafficking mediates the
dynamic asymmetric distribution of PIN FORMED (PIN) carriers, which drive polar
cell-to-cell transport of the hormone auxin, thereby generating auxin maxima and
minima that control development. The Arabidopsis PINOID (PID) protein kinase instructs
apical PIN localization by phosphorylating PINs. Here, we identified the PID homologs
WAG1 and WAG2 as new PIN polarity regulators. We show that the AGC3 kinases PID,
WAG1 and WAG2, and not other plant AGC kinases, instruct recruitment of PINs into
the apical recycling pathway by phosphorylating the middle serine in three conserved
TPRXS(N/S) motifs within the PIN central hydrophilic loop. Our results put forward
a model by which apolarly localized PID, WAG1 and WAG2 phosphorylate PINs at the
plasma membrane after default non-polar PIN secretion, and trigger endocytosis-dependent
apical PIN recycling. This phosphorylation-triggered apical PIN recycling competes
with ARF-GEF GNOM-dependent basal recycling to promote apical PIN localization.
In planta, expression domains of PID, WAG1 and WAG2 correlate with apical localization
of PINs in those cell types, indicating the importance of these kinases for apical
PIN localization. Our data show that by directing polar PIN localization and PIN-mediated
polar auxin transport, the three AGC3 kinases redundantly regulate cotyledon development,
root meristem size and gravitropic response, indicating their involvement in both
programmed and adaptive plant development.
