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: 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: '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: 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.
