text: 'Clathrin-mediated endocytosis (CME) regulates many aspects of plant development,
including hormone signaling and responses to environmental stresses. Despite the
importance of this process, the machinery that regulates CME in plants is largely
unknown. In mammals, the heterotetrameric ADAPTOR PROTEIN COMPLEX-2 (AP-2) is
required for the formation of clathrin-coated vesicles at the plasma membrane
(PM). Although the existence of AP-2 has been predicted in Arabidopsis thaliana,
the biochemistry and functionality of the complex is still uncharacterized. Here,
we identified all the subunits of the Arabidopsis AP-2 by tandem affinity purification
and found that one of the large AP-2 subunits, AP2A1, localized at the PM and
interacted with clathrin. Furthermore, endocytosis of the leucine-rich repeat
receptor kinase, BRASSINOSTEROID INSENSITIVE1 (BRI1), was shown to depend on AP-2.
Knockdown of the two Arabidopsis AP2A genes or overexpression of a dominant-negative
version of the medium AP-2 subunit, AP2M, impaired BRI1 endocytosis and enhanced
the brassinosteroid signaling. Our data reveal that the CME machinery in Arabidopsis
is evolutionarily conserved and that AP-2 functions in receptormediated endocytosis. '

text: The native auxin, indole-3-acetic acid (IAA), is a major regulator of plant
growth and development. Its nonuniform distribution between cells and tissues
underlies the spatiotemporal coordination of many developmental events and responses
to environmental stimuli. The regulation of auxin gradients and the formation
of auxin maxima/minima most likely involve the regulation of both metabolic and
transport processes. In this article, we have demonstrated that 2-oxindole-3-acetic
acid (oxIAA) is a major primary IAA catabolite formed in Arabidopsis thaliana
root tissues. OxIAA had little biological activity and was formed rapidly and
irreversibly in response to increases in auxin levels. We further showed that
there is cell type-specific regulation of oxIAA levels in the Arabidopsis root
apex. We propose that oxIAA is an important element in the regulation of output
from auxin gradients and, therefore, in the regulation of auxin homeostasis and
response mechanisms.

text: In plants, changes in local auxin concentrations can trigger a range of developmental
processes as distinct tissues respond differently to the same auxin stimulus.
However, little is known about how auxin is interpreted by individual cell types.
We performed a transcriptomic analysis of responses to auxin within four distinct
tissues of the Arabidopsis thaliana root and demonstrate that different cell types
show competence for discrete responses. The majority of auxin‐responsive genes
displayed a spatial bias in their induction or repression. The novel data set
was used to examine how auxin influences tissue‐specific transcriptional regulation
of cell‐identity markers. Additionally, the data were used in combination with
spatial expression maps of the root to plot a transcriptomic auxin‐response gradient
across the apical and basal meristem. The readout revealed a strong correlation
for thousands of genes between the relative response to auxin and expression along
the longitudinal axis of the root. This data set and comparative analysis provide
a transcriptome‐level spatial breakdown of the response to auxin within an organ
where this hormone mediates many aspects of development.

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: Establishment of the embryonic axis foreshadows the main body axis of adults
both in plants and in animals, but underlying mechanisms are considered distinct.
Plants utilize directional, cell-to-cell transport of the growth hormone auxin
[1, 2] to generate an asymmetric auxin response that specifies the embryonic apical-basal
axis [3-6]. The auxin flow directionality depends on the polarized subcellular
localization of PIN-FORMED (PIN) auxin transporters [7, 8]. It remains unknown
which mechanisms and spatial cues guide cell polarization and axis orientation
in early embryos. Herein, we provide conceptually novel insights into the formation
of embryonic axis in Arabidopsis by identifying a crucial role of localized tryptophan-dependent
auxin biosynthesis [9-12]. Local auxin production at the base of young embryos
and the accompanying PIN7-mediated auxin flow toward the proembryo are required
for the apical auxin response maximum and the specification of apical embryonic
structures. Later in embryogenesis, the precisely timed onset of localized apical
auxin biosynthesis mediates PIN1 polarization, basal auxin response maximum, and
specification of the root pole. Thus, the tight spatiotemporal control of distinct
local auxin sources provides a necessary, non-cell-autonomous trigger for the
coordinated cell polarization and subsequent apical-basal axis orientation during
embryogenesis and, presumably, also for other polarization events during postembryonic
plant life [13, 14].

text: The mode of action of auxin is based on its non-uniform distribution within
tissues and organs. Despite the wide use of several auxin analogues in research
and agriculture, little is known about the specificity of different auxin-related
transport and signalling processes towards these compounds. Using seedlings of
Arabidopsis thaliana and suspension-cultured cells of Nicotiana tabacum (BY-2),
the physiological activity of several auxin analogues was investigated, together
with their capacity to induce auxin-dependent gene expression, to inhibit endocytosis
and to be transported across the plasma membrane. This study shows that the specificity
criteria for different auxin-related processes vary widely. Notably, the special
behaviour of some synthetic auxin analogues suggests that they might be useful
tools in investigations of the molecular mechanism of auxin action. Thus, due
to their differential stimulatory effects on DR5 expression, indole-3-propionic
(IPA) and 2,4,5-trichlorophenoxy acetic (2,4,5-T) acids can serve in studies of
TRANSPORT INHIBITOR RESPONSE 1/AUXIN SIGNALLING F-BOX (TIR1/AFB)-mediated auxin
signalling, and 5-fluoroindole-3-acetic acid (5-F-IAA) can help to discriminate
between transcriptional and non-transcriptional pathways of auxin signalling.
The results demonstrate that the major determinants for the auxin-like physiological
potential of a particular compound are very complex and involve its chemical and
metabolic stability, its ability to distribute in tissues in a polar manner and
its activity towards auxin signalling machinery.
