text: The apical hook is a transiently formed structure that plays a protective
role when the germinating seedling penetrates through the soil towards the surface.
Crucial for proper bending is the local auxin maxima, which defines the concave
(inner) side of the hook curvature. As no sign of asymmetric auxin distribution
has been reported in embryonic hypocotyls prior to hook formation, the question
of how auxin asymmetry is established in the early phases of seedling germination
remains largely unanswered. Here, we analyzed the auxin distribution and expression
of PIN auxin efflux carriers from early phases of germination, and show that bending
of the root in response to gravity is the crucial initial cue that governs the
hypocotyl bending required for apical hook formation. Importantly, polar auxin
transport machinery is established gradually after germination starts as a result
of tight root-hypocotyl interaction and a proper balance between abscisic acid
and gibberellins.

text: Differential cell growth enables flexible organ bending in the presence of
environmental signals such as light or gravity. A prominent example of the developmental
processes based on differential cell growth is the formation of the apical hook
that protects the fragile shoot apical meristem when it breaks through the soil
during germination. Here, we combined in silico and in vivo approaches to identify
a minimal mechanism producing auxin gradient-guided differential growth during
the establishment of the apical hook in the model plant Arabidopsis thaliana.
Computer simulation models based on experimental data demonstrate that asymmetric
expression of the PIN-FORMED auxin efflux carrier at the concave (inner) versus
convex (outer) side of the hook suffices to establish an auxin maximum in the
epidermis at the concave side of the apical hook. Furthermore, we propose a mechanism
that translates this maximum into differential growth, and thus curvature, of
the apical hook. Through a combination of experimental and in silico computational
approaches, we have identified the individual contributions of differential cell
elongation and proliferation to defining the apical hook and reveal the role of
auxin-ethylene crosstalk in balancing these two processes. © 2016 American Society

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: '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: 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-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: 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.
