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: 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: 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: 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: Plant-specific PIN-formed (PIN) efflux transporters for the plant hormone
auxin are required for tissue-specific directional auxin transport and cellular
auxin homeostasis. The Arabidopsis PIN protein family has been shown to play important
roles in developmental processes such as embryogenesis, organogenesis, vascular
tissue differentiation, root meristem patterning and tropic growth. Here we analyzed
roles of the less characterised Arabidopsis PIN6 auxin transporter. PIN6 is auxin-inducible
and is expressed during multiple auxin-regulated developmental processes. Loss
of pin6 function interfered with primary root growth and lateral root development.
Misexpression of PIN6 affected auxin transport and interfered with auxin homeostasis
in other growth processes such as shoot apical dominance, lateral root primordia
development, adventitious root formation, root hair outgrowth and root waving.
These changes in auxin-regulated growth correlated with a reduction in total auxin
transport as well as with an altered activity of DR5-GUS auxin response reporter.
Overall, the data indicate that PIN6 regulates auxin homeostasis during plant
development.

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.

text: Lateral root (LR) formation is initiated when pericycle cells accumulate auxin,
thereby acquiring founder cell (FC) status and triggering asymmetric cell divisions,
giving rise to a new primordium. How this auxin maximum in pericycle cells builds
up and remains focused is not understood. We report that the endodermis plays
an active role in the regulation of auxin accumulation and is instructive for
FCs to progress during the LR initiation (LRI) phase. We describe the functional
importance of a PIN3 (PIN-formed) auxin efflux carrier-dependent hormone reflux
pathway between overlaying endodermal and pericycle FCs. Disrupting this reflux
pathway causes dramatic defects in the progress of FCs towards the next initiation
phase. Our data identify an unexpected regulatory function for the endodermis
in LRI as part of the fine-tuning mechanism that appears to act as a check point
in LR organogenesis after FCs are specified.

text: The apical-basal axis of the early plant embryo determines the body plan of
the adult organism. To establish a polarized embryonic axis, plants evolved a
unique mechanism that involves directional, cell-to-cell transport of the growth
regulator auxin. Auxin transport relies on PIN auxin transporters [1], whose polar
subcellular localization determines the flow directionality. PIN-mediated auxin
transport mediates the spatial and temporal activity of the auxin response machinery
[2-7] that contributes to embryo patterning processes, including establishment
of the apical (shoot) and basal (root) embryo poles [8]. However, little is known
of upstream mechanisms guiding the (re)polarization of auxin fluxes during embryogenesis
[9]. Here, we developed a model of plant embryogenesis that correctly generates
emergent cell polarities and auxin-mediated sequential initiation of apical-basal
axis of plant embryo. The model relies on two precisely localized auxin sources
and a feedback between auxin and the polar, subcellular PIN transporter localization.
Simulations reproduced PIN polarity and auxin distribution, as well as previously
unknown polarization events during early embryogenesis. The spectrum of validated
model predictions suggests that our model corresponds to a minimal mechanistic
framework for initiation and orientation of the apical-basal axis to guide both
embryonic and postembryonic plant development.

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.
