text: Extracellular matrices (ECMs) are central to the advent of multicellular life,
and their mechanical propertiesare modulated by and impinge on intracellular signaling
pathways that regulate vital cellular functions. High spatial-resolution mapping
of mechanical properties in live cells is, however, extremely challenging. Thus,
our understanding of how signaling pathways process physiological signals to generate
appropriate mechanical responses is limited. We introduce fluorescence emission-Brillouin
scattering imaging (FBi), a method for the parallel and all-optical measurements
of mechanical properties and fluorescence at the submicrometer scale in living
organisms. Using FBi, we showed thatchanges in cellular hydrostatic pressure and
cytoplasm viscoelasticity modulate the mechanical signatures of plant ECMs. We
further established that the measured "stiffness" of plant ECMs is symmetrically
patternedin hypocotyl cells undergoing directional growth. Finally, application
of this method to Arabidopsis thaliana with photoreceptor mutants revealed that
red and far-red light signals are essential modulators of ECM viscoelasticity.
By mapping the viscoelastic signatures of a complex ECM, we provide proof of principlefor
the organism-wide applicability of FBi for measuring the mechanical outputs of
intracellular signaling pathways. As such, our work has implications for investigations
of mechanosignaling pathways and developmental biology.

text: Plants are continuously exposed to a myriad of external signals such as fluctuating
nutrients availability, drought, heat, cold, high salinity, or pathogen/pest attacks
that can severely affect their development, growth, and fertility. As sessile
organisms, plants must therefore be able to sense and rapidly react to these external
inputs, activate efficient responses, and adjust development to changing conditions.
In recent years, significant progress has been made towards understanding the
molecular mechanisms underlying the intricate and complex communication between
plants and the environment. It is now becoming increasingly evident that hormones
have an important regulatory role in plant adaptation and defense mechanisms.

text: Lateral root primordia (LRP) originate from pericycle stem cells located deep
within parental root tissues. LRP emerge through overlying root tissues by inducing
auxin-dependent cell separation and hydraulic changes in adjacent cells. The auxin-inducible
auxin influx carrier LAX3 plays a key role concentrating this signal in cells
overlying LRP. Delimiting LAX3 expression to two adjacent cell files overlying
new LRP is crucial to ensure that auxin-regulated cell separation occurs solely
along their shared walls. Multiscale modeling has predicted that this highly focused
pattern of expression requires auxin to sequentially induce auxin efflux and influx
carriers PIN3 and LAX3, respectively. Consistent with model predictions, we report
that auxin-inducible LAX3 expression is regulated indirectly by AUXIN RESPONSE
FACTOR 7 (ARF7). Yeast one-hybrid screens revealed that the LAX3 promoter is bound
by the transcription factor LBD29, which is a direct target for regulation by
ARF7. Disrupting auxin-inducible LBD29 expression or expressing an LBD29-SRDX
transcriptional repressor phenocopied the lax3 mutant, resulting in delayed lateral
root emergence. We conclude that sequential LBD29 and LAX3 induction by auxin
is required to coordinate cell separation and organ emergence.

text: Synchronized tissue polarization during regeneration or de novo vascular tissue
formation is a plant-specific example of intercellular communication and coordinated
development. According to the canalization hypothesis, the plant hormone auxin
serves as polarizing signal that mediates directional channel formation underlying
the spatio-temporal vasculature patterning. A necessary part of canalization is
a positive feedback between auxin signaling and polarity of the intercellular
auxin flow. The cellular and molecular mechanisms of this process are still poorly
understood, not the least, because of a lack of a suitable model system. We show
that the main genetic model plant, Arabidopsis (Arabidopsis thaliana) can be used
to study the canalization during vascular cambium regeneration and new vasculature
formation. We monitored localized auxin responses, directional auxin-transport
channels formation, and establishment of new vascular cambium polarity during
regenerative processes after stem wounding. The increased auxin response above
and around the wound preceded the formation of PIN1 auxin transporter-marked channels
from the primarily homogenous tissue and the transient, gradual changes in PIN1
localization preceded the polarity of newly formed vascular tissue. Thus, Arabidopsis
is a useful model for studies of coordinated tissue polarization and vasculature
formation after wounding allowing for genetic and mechanistic dissection of the
canalization hypothesis.

text: Plants are able to modulate root growth and development to optimize their
nitrogen nutrition. In Arabidopsis (Arabidopsis thaliana), the adaptive root response
to nitrate (NO3 -) depends on the NRT1.1/NPF6.3 transporter/sensor. NRT1.1 represses
emergence of lateral root primordia (LRPs) at low concentration or absence of
NO3 - through its auxin transport activity that lowers auxin accumulation in LR.
However, these functional data strongly contrast with the known transcriptional
regulation of NRT1.1, which is markedly repressed in LRPs in the absence of NO3
-. To explain this discrepancy, we investigated in detail the spatiotemporal expression
pattern of the NRT1.1 protein during LRP development and combined local transcript
analysis with the use of transgenic lines expressing tagged NRT1.1 proteins. Our
results show that although NO3 - stimulates NRT1.1 transcription and probably
mRNA stability both in primary root tissues and in LRPs, it acts differentially
on protein accumulation, depending on the tissues considered with stimulation
in cortex and epidermis of the primary root and a strong repression in LRPs and
to a lower extent at the primary root tip. This demonstrates that NRT1.1 is strongly
regulated at the posttranscriptional level by tissue-specific mechanisms. These
mechanisms are crucial for controlling the large palette of adaptive responses
to NO3 - mediated by NRT1.1 as they ensure that the protein is present in the
proper tissue under the specific conditions where it plays a signaling role in
this particular tissue.

text: The impact of the plant hormone ethylene on seedling development has long
been recognized; however, its ecophysiological relevance is unexplored. Three
recent studies demonstrate that ethylene is a critical endogenous integrator of
various environmental signals including mechanical stress, light, and oxygen availability
during seedling germination and growth through the soil.

text: To sustain a lifelong ability to initiate organs, plants retain pools of undifferentiated
cells with a preserved prolif eration capacity. The root pericycle represents
a unique tissue with conditional meristematic activity, and its tight control
determines initiation of lateral organs. Here we show that the meristematic activity
of the pericycle is constrained by the interaction with the adjacent endodermis.
Release of these restraints by elimination of endo dermal cells by single-cell
ablation triggers the pericycle to re-enter the cell cycle. We found that endodermis
removal substitutes for the phytohormone auxin-dependent initiation of the pericycle
meristematic activity. However, auxin is indispensable to steer the cell division
plane orientation of new organ-defining divisions. We propose a dual, spatiotemporally
distinct role for auxin during lateral root initiation. In the endodermis, auxin
releases constraints arising from cell-to-cell interactions that compromise the
pericycle meristematic activity, whereas, in the pericycle, auxin defines the
orientation of the cell division plane to initiate lateral roots.

text: The asymmetric localization of proteins in the plasma membrane domains of
eukaryotic cells is a fundamental manifestation of cell polarity that is central
to multicellular organization and developmental patterning. In plants, the mechanisms
underlying the polar localization of cargo proteins are still largely unknown
and appear to be fundamentally distinct from those operating in mammals. Here,
we present a systematic, quantitative comparative analysis of the polar delivery
and subcellular localization of proteins that characterize distinct polar plasma
membrane domains in plant cells. The combination of microscopic analyses and computational
modeling revealed a mechanistic framework common to diverse polar cargos and underlying
the establishment and maintenance of apical, basal, and lateral polar domains
in plant cells. This mechanism depends on the polar secretion, constitutive endocytic
recycling, and restricted lateral diffusion of cargos within the plasma membrane.
Moreover, our observations suggest that polar cargo distribution involves the
individual protein potential to form clusters within the plasma membrane and interact
with the extracellular matrix. Our observations provide insights into the shared
cellular mechanisms of polar cargo delivery and polarity maintenance in plant
cells.

text: 'Cytokinin is a phytohormone that is well known for its roles in numerous
plant growth and developmental processes, yet it has also been linked to abiotic
stress response in a less defined manner. Arabidopsis (Arabidopsis thaliana) Cytokinin
Response Factor 6 (CRF6) is a cytokinin-responsive AP2/ERF-family transcription
factor that, through the cytokinin signaling pathway, plays a key role in the
inhibition of dark-induced senescence. CRF6 expression is also induced by oxidative
stress, and here we show a novel function for CRF6 in relation to oxidative stress
and identify downstream transcriptional targets of CRF6 that are repressed in
response to oxidative stress. Analysis of transcriptomic changes in wild-type
and crf6 mutant plants treated with H2O2 identified CRF6-dependent differentially
expressed transcripts, many of which were repressed rather than induced. Moreover,
many repressed genes also show decreased expression in 35S:CRF6 overexpressing
plants. Together, these findings suggest that CRF6 functions largely as a transcriptional
repressor. Interestingly, among the H2O2 repressed CRF6-dependent transcripts
was a set of five genes associated with cytokinin processes: (signaling) ARR6,
ARR9, ARR11, (biosynthesis) LOG7, and (transport) ABCG14. We have examined mutants
of these cytokinin-associated target genes to reveal novel connections to oxidative
stress. Further examination of CRF6-DNA interactions indicated that CRF6 may regulate
its targets both directly and indirectly. Together, this shows that CRF6 functions
during oxidative stress as a negative regulator to control this cytokinin-associated
module of CRF6- dependent genes and establishes a novel connection between cytokinin

text: 'Plant sexual reproduction involves highly structured and specialized organs:
stamens (male) and gynoecia (female, containing ovules). These organs synchronously
develop within protective flower buds, until anthesis, via tightly coordinated
mechanisms that are essential for effective fertilization and production of viable
seeds. The phytohormone auxin is one of the key endogenous signalling molecules
controlling initiation and development of these, and other, plant organs. In particular,
its uneven distribution, resulting from tightly controlled production, metabolism
and directional transport, is an important morphogenic factor. In this review
we discuss how developmentally controlled and localized auxin biosynthesis and
transport contribute to the coordinated development of plants'' reproductive organs,
and their fertilized derivatives (embryos) via the regulation of auxin levels
and distribution within and around them. Current understanding of the links between
de novo local auxin biosynthesis, auxin transport and/or signalling is presented
to highlight the importance of the non-cell autonomous action of auxin production
on development and morphogenesis of reproductive organs and embryos. An overview
of transcription factor families, which spatiotemporally define local auxin production
by controlling key auxin biosynthetic enzymes, is also presented.'

text: Multiple plant developmental processes, such as lateral root development,
depend on auxin distribution patterns that are in part generated by the PIN-formed
family of auxin-efflux transporters. Here we propose that AUXIN RESPONSE FACTOR7
(ARF7) and the ARF7-regulated FOUR LIPS/MYB124 (FLP) transcription factors jointly
form a coherent feed-forward motif that mediates the auxin-responsive PIN3 transcription
in planta to steer the early steps of lateral root formation. This regulatory
mechanism might endow the PIN3 circuitry with a temporal 'memory' of auxin stimuli,
potentially maintaining and enhancing the robustness of the auxin flux directionality
during lateral root development. The cooperative action between canonical auxin
signalling and other transcription factors might constitute a general mechanism
by which transcriptional auxin-sensitivity can be regulated at a tissue-specific
level.

text: 'Plants are sessile organisms that are permanently restricted to their site
of germination. To compensate for their lack of mobility, plants evolved unique
mechanisms enabling them to rapidly react to ever changing environmental conditions
and flexibly adapt their postembryonic developmental program. A prominent demonstration
of this developmental plasticity is their ability to bend organs in order to reach
the position most optimal for growth and utilization of light, nutrients, and
other resources. Shortly after germination, dicotyledonous seedlings form a bended
structure, the so-called apical hook, to protect the delicate shoot meristem and
cotyledons from damage when penetrating through the soil. Upon perception of a
light stimulus, the apical hook rapidly opens and the photomorphogenic developmental
program is activated. After germination, plant organs are able to align their
growth with the light source and adopt the most favorable orientation through
bending, in a process named phototropism. On the other hand, when roots and shoots
are diverted from their upright orientation, they immediately detect a change
in the gravity vector and bend to maintain a vertical growth direction. Noteworthy,
despite the diversity of external stimuli perceived by different plant organs,
all plant tropic movements share a common mechanistic basis: differential cell
growth. In our review, we will discuss the molecular principles underlying various
tropic responses with the focus on mechanisms mediating the perception of external
signals, transduction cascades and downstream responses that regulate differential
cell growth and consequently, organ bending. In particular, we highlight common
and specific features of regulatory pathways in control of the bending of organs
and a role for the plant hormone auxin as a key regulatory component.'

text: Auxin and cytokinin are key endogenous regulators of plant development. Although
cytokinin-mediated modulation of auxin distribution is a developmentally crucial
hormonal interaction, its molecular basis is largely unknown. Here we show a direct
regulatory link between cytokinin signalling and the auxin transport machinery
uncovering a mechanistic framework for cytokinin-auxin cross-talk. We show that
the CYTOKININ RESPONSE FACTORS (CRFs), transcription factors downstream of cytokinin
perception, transcriptionally control genes encoding PIN-FORMED (PIN) auxin transporters
at a specific PIN CYTOKININ RESPONSE ELEMENT (PCRE) domain. Removal of this cis-regulatory
element effectively uncouples PIN transcription from the CRF-mediated cytokinin
regulation and attenuates plant cytokinin sensitivity. We propose that CRFs represent
a missing cross-talk component that fine-tunes auxin transport capacity downstream
of cytokinin signalling to control plant development.

text: The prominent and evolutionarily ancient role of the plant hormone auxin is
the regulation of cell expansion. Cell expansion requires ordered arrangement
of the cytoskeleton but molecular mechanisms underlying its regulation by signalling
molecules including auxin are unknown. Here we show in the model plant Arabidopsis
thaliana that in elongating cells exogenous application of auxin or redistribution
of endogenous auxin induces very rapid microtubule re-orientation from transverse
to longitudinal, coherent with the inhibition of cell expansion. This fast auxin
effect requires auxin binding protein 1 (ABP1) and involves a contribution of
downstream signalling components such as ROP6 GTPase, ROP-interactive protein
RIC1 and the microtubule-severing protein katanin. These components are required
for rapid auxin-and ABP1-mediated re-orientation of microtubules to regulate cell
elongation in roots and dark-grown hypocotyls as well as asymmetric growth during
gravitropic responses.

text: Plant embryogenesis is regulated by differential distribution of the plant
hormone auxin. However, the cells establishing these gradients during microspore
embryogenesis remain to be identified. For the first time, we describe, using
the DR5 or DR5rev reporter gene systems, the GFP- and GUS-based auxin biosensors
to monitor auxin during Brassica napus androgenesis at cellular resolution in
the initial stages. Our study provides evidence that the distribution of auxin
changes during embryo development and depends on the temperature-inducible in
vitro culture conditions. For this, microspores (mcs) were induced to embryogenesis
by heat treatment and then subjected to genetic modification via Agrobacterium
tumefaciens. The duration of high temperature treatment had a significant influence
on auxin distribution in isolated and in vitro-cultured microspores and on microspore-derived
embryo development. In the “mild” heat-treated (1 day at 32 °C) mcs, auxin localized
in a polar way already at the uni-nucleate microspore, which was critical for
the initiation of embryos with suspensor-like structure. Assuming a mean mcs radius
of 20 μm, endogenous auxin content in a single cell corresponded to concentration
of 1.01 μM. In mcs subjected to a prolonged heat (5 days at 32 °C), although auxin
concentration increased dozen times, auxin polarization was set up at a few-celled
pro-embryos without suspensor. Those embryos were enclosed in the outer wall called
the exine. The exine rupture was accompanied by the auxin gradient polarization.
Relative quantitative estimation of auxin, using time-lapse imaging, revealed
that primordia possess up to 1.3-fold higher amounts than those found in the root
apices of transgenic MDEs in the presence of exogenous auxin. Our results show,
for the first time, which concentration of endogenous auxin coincides with the
first cell division and how the high temperature interplays with auxin, by what
affects delay early establishing microspore polarity. Moreover, we present how
the local auxin accumulation demonstrates the apical–basal axis formation of the
androgenic embryo and directs the axiality of the adult haploid plant.

text: Germination of Arabidopsis seeds in darkness induces apical hook development,
based on a tightly regulated differential growth coordinated by a multiple hormone
cross-talk. Here, we endeavoured to clarify the function of brassinosteroids (BRs)
and cross-talk with ethylene in hook development. An automated infrared imaging
system was developed to study the kinetics of hook development in etiolated Arabidopsis
seedlings. To ascertain the photomorphogenic control of hook opening, the system
was equipped with an automatic light dimmer. We demonstrate that ethylene and
BRs are indispensable for hook formation and maintenance. Ethylene regulation
of hook formation functions partly through BRs, with BR feedback inhibition of
ethylene action. Conversely, BR-mediated extension of hook maintenance functions
partly through ethylene. Furthermore, we revealed that a short light pulse is
sufficient to induce rapid hook opening. Our dynamic infrared imaging system allows
high-resolution, kinetic imaging of up to 112 seedlings in a single experimental
run. At this high throughput, it is ideally suited to rapidly gain insight in
pathway networks. We demonstrate that BRs and ethylene cooperatively regulate
apical hook development in a phase-dependent manner. Furthermore, we show that
light is a predominant regulator of hook opening, inhibiting ethylene- and BR-mediated
postponement of hook opening.

text: The plant hormones auxin and cytokinin mutually coordinate their activities
to control various aspects of development [1-9], and their crosstalk occurs at
multiple levels [10, 11]. Cytokinin-mediated modulation of auxin transport provides
an efficient means to regulate auxin distribution in plant organs. Here, we demonstrate
that cytokinin does not merely control the overall auxin flow capacity, but might
also act as a polarizing cue and control the auxin stream directionality during
plant organogenesis. Cytokinin enhances the PIN-FORMED1 (PIN1) auxin transporter
depletion at specific polar domains, thus rearranging the cellular PIN polarities
and directly regulating the auxin flow direction. This selective cytokinin sensitivity
correlates with the PIN protein phosphorylation degree. PIN1 phosphomimicking
mutations, as well as enhanced phosphorylation in plants with modulated activities
of PIN-specific kinases and phosphatases, desensitize PIN1 to cytokinin. Our results
reveal conceptually novel, cytokinin-driven polarization mechanism that operates
in developmental processes involving rapid auxin stream redirection, such as lateral
root organogenesis, in which a gradual PIN polarity switch defines the growth
axis of the newly formed organ.

text: The Balkan Peninsula, characterized by high rates of endemism, is recognised
as one of the most diverse and species-rich areas of Europe. However, little is
known about the origin of Balkan endemics. The present study addresses the phylogenetic
position of the Balkan endemic Ranunculus wettsteinii, as well as its taxonomic
status and relationship with the widespread R. parnassiifolius, based on nuclear
DNA (internal transcribed spacer, ITS) and plastid regions (rpl32-trnL, rps16-trnQ,
trnK-matK and ycf6-psbM). Maximum parsimony and Bayesian inference analyses revealed
a well-supported clade formed by accessions of R. wettsteinii. Furthermore, our
phylogenetic and network analyses supported previous hypotheses of a likely allopolyploid
origin for R. wettsteinii between R. montenegrinus and R. parnassiifolius, with
the latter as the maternal parent.

text: As soon as a seed germinates, plant growth relates to gravity to ensure that
the root penetrates the soil and the shoot expands aerially. Whereas mechanisms
of positive and negative orthogravitropism of primary roots and shoots are relatively
well understood [1-3], lateral organs often show more complex growth behavior
[4]. Lateral roots (LRs) seemingly suppress positive gravitropic growth and show
a defined gravitropic set-point angle (GSA) that allows radial expansion of the
root system (plagiotropism) [3, 4]. Despite its eminent importance for root architecture,
it so far remains completely unknown how lateral organs partially suppress positive
orthogravitropism. Here we show that the phytohormone auxin steers GSA formation
and limits positive orthogravitropism in LR. Low and high auxin levels/signaling
lead to radial or axial root systems, respectively. At a cellular level, it is
the auxin transport-dependent regulation of asymmetric growth in the elongation
zone that determines GSA. Our data suggest that strong repression of PIN4/PIN7
and transient PIN3 expression limit auxin redistribution in young LR columella
cells. We conclude that PIN activity, by temporally limiting the asymmetric auxin
fluxes in the tip of LRs, induces transient, differential growth responses in
the elongation zone and, consequently, controls root architecture.
