text: Availability of the essential macronutrient nitrogen in soil plays a critical
role in plant growth, development, and impacts agricultural productivity. Plants
have evolved different strategies for sensing and responding to heterogeneous
nitrogen distribution. Modulation of root system architecture, including primary
root growth and branching, is among the most essential plant adaptions to ensure
adequate nitrogen acquisition. However, the immediate molecular pathways coordinating
the adjustment of root growth in response to distinct nitrogen sources, such as
nitrate or ammonium, are poorly understood. Here, we show that growth as manifested
by cell division and elongation is synchronized by coordinated auxin flux between
two adjacent outer tissue layers of the root. This coordination is achieved by
nitrate‐dependent dephosphorylation of the PIN2 auxin efflux carrier at a previously
uncharacterized phosphorylation site, leading to subsequent PIN2 lateralization
and thereby regulating auxin flow between adjacent tissues. A dynamic computer
model based on our experimental data successfully recapitulates experimental observations.
Our study provides mechanistic insights broadening our understanding of root growth
mechanisms in dynamic environments.

text: Plants as non-mobile organisms constantly integrate varying environmental
signals to flexibly adapt their growth and development. Local fluctuations in
water and nutrient availability, sudden changes in temperature or other abiotic
and biotic stresses can trigger changes in the growth of plant organs. Multiple
mutually interconnected hormonal signaling cascades act as essential endogenous
translators of these exogenous signals in the adaptive responses of plants. Although
the molecular backbones of hormone transduction pathways have been identified,
the mechanisms underlying their interactions are largely unknown. Here, using
genome wide transcriptome profiling we identify an auxin and cytokinin cross-talk
component; SYNERGISTIC ON AUXIN AND CYTOKININ 1 (SYAC1), whose expression in roots
is strictly dependent on both of these hormonal pathways. We show that SYAC1 is
a regulator of secretory pathway, whose enhanced activity interferes with deposition
of cell wall components and can fine-tune organ growth and sensitivity to soil
pathogens.

text: In agricultural systems, nitrate is the main source of nitrogen available
for plants. Besides its role as a nutrient, nitrate has been shown to act as a
signal molecule for plant growth, development and stress responses. In Arabidopsis,
the NRT1.1 nitrate transceptor represses lateral root (LR) development at low
nitrate availability by promoting auxin basipetal transport out of the LR primordia
(LRPs). In addition, our present study shows that NRT1.1 acts as a negative regulator
of the TAR2 auxin biosynthetic gene expression in the root stele. This is expected
to repress local auxin biosynthesis and thus to reduce acropetal auxin supply
to the LRPs. Moreover, NRT1.1 also negatively affects expression of the LAX3 auxin
influx carrier, thus preventing cell wall remodeling required for overlying tissues
separation during LRP emergence. Both NRT1.1-mediated repression of TAR2 and LAX3
are suppressed at high nitrate availability, resulting in the nitrate induction
of TAR2 and LAX3 expression that is required for optimal stimulation of LR development
by nitrate. Altogether, our results indicate that the NRT1.1 transceptor coordinately
controls several crucial auxin-associated processes required for LRP development,
and as a consequence that NRT1.1 plays a much more integrated role than previously
anticipated in regulating the nitrate response of root system architecture.

text: Seeds derive from ovules upon fertilization and therefore the total number
of ovules determines the final seed yield, a fundamental trait in crop plants.
Among the factors that co-ordinate the process of ovule formation, the transcription
factors CUP-SHAPED COTYLEDON 1 (CUC1) and CUC2 and the hormone cytokinin (CK)
have a particularly prominent role. Indeed, the absence of both CUC1 and CUC2
causes a severe reduction in ovule number, a phenotype that can be rescued by
CK treatment. In this study, we combined CK quantification with an integrative
genome-wide target identification approach to select Arabidopsis genes regulated
by CUCs that are also involved in CK metabolism. We focused our attention on the
functional characterization of UDP-GLUCOSYL TRANSFERASE 85A3 (UGT85A3) and UGT73C1,
which are up-regulated in the absence of CUC1 and CUC2 and encode enzymes able
to catalyse CK inactivation by O-glucosylation. Our results demonstrate a role
for these UGTs as a link between CUCs and CK homeostasis, and highlight the importance
of CUCs and CKs in the determination of seed yield.

text: In plants, the multistep phosphorelay (MSP) pathway mediates a range of regulatory
processes, including those activated by cytokinins. The crosstalk between cytokinin
response and light is known for a long time. However, the molecular mechanism
underlying the interactionbetween light and cytokinin signaling remains elusive.
In the screen for upstream regulators we identified a LONG PALE HYPOCOTYL (LPH)
gene whose activity is indispensable for spatiotemporally correct expression of
CYTOKININ INDEPENDENT-1 (CKI1), encoding the constitutively active sensor histidine
kinase that activates MSP signaling. lph is a new allele of HEME OXYGENASE 1 (HY1)
which encodes the key protein in the biosynthesis of phytochromobilin, a cofactor
of photoconvertiblephytochromes. Our analysis confirmed the light-dependent regulation
oftheCKI1 expression pattern. We show that CKI1 expression is under the control
of phytochrome A (phyA), functioning as a dual (both positive and negative) regulator
of CKI1 expression, presumably via the phyA-regulated transcription factors PHYTOCHROME
INTERACTING FACTOR 3 (PIF3) and CIRCADIAN CLOCK ASSOCIATED 1 (CCA1). Changes in
CKI1 expression observed in lph/hy1-7 and phy mutants correlatewithmisregulation
of MSP signaling, changedcytokinin sensitivity and developmental aberrations,previously
shown to be associated with cytokinin and/or CKI1 action. Besides that, we demonstrate
novel role of phyA-dependent CKI1 expression in the hypocotyl elongation and hook
development during skotomorphogenesis. Based on these results, we propose that
the light-dependent regulation of CKI1 provides a plausible mechanistic link underlying
the well-known interaction between light- and cytokinin-controlled plant development.

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: 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 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: 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.

text: Upon hormonal signaling, ovules develop as lateral organs from the placenta.
Ovule numbers ultimately determine the number of seeds that develop, and thereby
contribute to the final seed yield in crop plants. We demonstrate here that CUP-SHAPED
COTYLEDON 1 (CUC1), CUC2 and AINTEGUMENTA (ANT) have additive effects on ovule
primordia formation. We show that expression of the CUC1 and CUC2 genes is required
to redundantly regulate expression of PINFORMED1 (PIN1), which in turn is required
for ovule primordia formation. Furthermore, our results suggest that the auxin
response factor MONOPTEROS (MP/ARF5) may directly bind ANT, CUC1 and CUC2 and
promote their transcription. Based on our findings, we propose an integrative
model to describe the molecular mechanisms of the early stages of ovule development.

text: The architecture of a plant's root system, established postembryonically,
results from both coordinated root growth and lateral root branching. The plant
hormones auxin and cytokinin are central endogenous signaling molecules that regulate
lateral root organogenesis positively and negatively, respectively. Tight control
and mutual balance of their antagonistic activities are particularly important
during the early phases of lateral root organogenesis to ensure continuous lateral
root initiation (LRI) and proper development of lateral root primordia (LRP).
Here, we show that the early phases of lateral root organogenesis, including priming
and initiation, take place in root zones with a repressed cytokinin response.
Accordingly, ectopic overproduction of cytokinin in the root basal meristem most
efficiently inhibits LRI. Enhanced cytokinin responses in pericycle cells between
existing LRP might restrict LRI near existing LRP and, when compromised, ectopic
LRI occurs. Furthermore, our results demonstrate that young LRP are more sensitive
to perturbations in the cytokinin activity than are developmentally more advanced
primordia. We hypothesize that the effect of cytokinin on the development of primordia
possibly depends on the robustness and stability of the auxin gradient.
