text: Plant morphogenesis relies exclusively on oriented cell expansion and division.
Nonetheless, the mechanism(s) determining division plane orientation remain elusive.
Here, we studied tissue healing after laser-assisted wounding in roots of Arabidopsis
thaliana and uncovered how mechanical forces stabilize and reorient the microtubule
cytoskeleton for the orientation of cell division. We identified that root tissue
functions as an interconnected cell matrix, with a radial gradient of tissue extendibility
causing predictable tissue deformation after wounding. This deformation causes
instant redirection of expansion in the surrounding cells and reorientation of
microtubule arrays, ultimately predicting cell division orientation. Microtubules
are destabilized under low tension, whereas stretching of cells, either through
wounding or external aspiration, immediately induces their polymerization. The
higher microtubule abundance in the stretched cell parts leads to the reorientation
of microtubule arrays and, ultimately, informs cell division planes. This provides
a long-sought mechanism for flexible re-arrangement of cell divisions by mechanical
forces for tissue reconstruction and plant architecture.

text: Wound healing in plant tissues, consisting of rigid cell wall-encapsulated
cells, represents a considerable challenge and occurs through largely unknown
mechanisms distinct from those in animals. Owing to their inability to migrate,
plant cells rely on targeted cell division and expansion to regenerate wounds.
Strict coordination of these wound-induced responses is essential to ensure efficient,
spatially restricted wound healing. Single-cell tracking by live imaging allowed
us to gain mechanistic insight into the wound perception and coordination of wound
responses after laser-based wounding in Arabidopsis root. We revealed a crucial
contribution of the collapse of damaged cells in wound perception and detected
an auxin increase specific to cells immediately adjacent to the wound. This localized
auxin increase balances wound-induced cell expansion and restorative division
rates in a dose-dependent manner, leading to tumorous overproliferation when the
canonical TIR1 auxin signaling is disrupted. Auxin and wound-induced turgor pressure
changes together also spatially define the activation of key components of regeneration,
such as the transcription regulator ERF115. Our observations suggest that the
wound signaling involves the sensing of collapse of damaged cells and a local
auxin signaling activation to coordinate the downstream transcriptional responses
in the immediate wound vicinity.

text: Multicellular development requires coordinated cell polarization relative
to body axes, and translation to oriented cell division 1–3 . In plants, it is
unknown how cell polarities are connected to organismal axes and translated to
division. Here, we identify Arabidopsis SOSEKI proteins that integrate apical–basal
and radial organismal axes to localize to polar cell edges. Localization does
not depend on tissue context, requires cell wall integrity and is defined by a
transferrable, protein-specific motif. A Domain of Unknown Function in SOSEKI
proteins resembles the DIX oligomerization domain in the animal Dishevelled polarity
regulator. The DIX-like domain self-interacts and is required for edge localization
and for influencing division orientation, together with a second domain that defines
the polar membrane domain. Our work shows that SOSEKI proteins locally interpret
global polarity cues and can influence cell division orientation. Furthermore,
this work reveals that, despite fundamental differences, cell polarity mechanisms
in plants and animals converge on a similar protein domain.

text: "A process of restorative patterning in plant roots correctly replaces eliminated
cells to heal local injuries despite the absence of cell migration, which underpins
wound healing in animals. \r\n\r\nPatterning in plants relies on oriented cell
divisions and acquisition of specific cell identities. Plants regularly endure
wounds caused by abiotic or biotic environmental stimuli and have developed extraordinary
abilities to restore their tissues after injuries. Here, we provide insight into
a mechanism of restorative patterning that repairs tissues after wounding. Laser-assisted
elimination of different cells in Arabidopsis root combined with live-imaging
tracking during vertical growth allowed analysis of the regeneration processes
in vivo. Specifically, the cells adjacent to the inner side of the injury re-activated
their stem cell transcriptional programs. They accelerated their progression through
cell cycle, coordinately changed the cell division orientation, and ultimately
acquired de novo the correct cell fates to replace missing cells. These observations
highlight existence of unknown intercellular positional signaling and demonstrate
the capability of specified cells to re-acquire stem cell programs as a crucial
part of the plant-specific mechanism of wound healing."

text: Plant organs are typically organized into three main tissue layers. The middle
ground tissue layer comprises the majority of the plant body and serves a wide
range of functions, including photosynthesis, selective nutrient uptake and storage,
and gravity sensing. Ground tissue patterning and maintenance in Arabidopsis are
controlled by a well-established gene network revolving around the key regulator
SHORT-ROOT (SHR). In contrast, it is completely unknown how ground tissue identity
is first specified from totipotent precursor cells in the embryo. The plant signaling
molecule auxin, acting through AUXIN RESPONSE FACTOR (ARF) transcription factors,
is critical for embryo patterning. The auxin effector ARF5/MONOPTEROS (MP) acts
both cell-autonomously and noncell-autonomously to control embryonic vascular
tissue formation and root initiation, respectively. Here we show that auxin response
and ARF activity cell-autonomously control the asymmetric division of the first
ground tissue cells. By identifying embryonic target genes, we show that MP transcriptionally
initiates the ground tissue lineage and acts upstream of the regulatory network
that controls ground tissue patterning and maintenance. Strikingly, whereas the
SHR network depends on MP, this MP function is, at least in part, SHR independent.
Our study therefore identifies auxin response as a regulator of ground tissue
specification in the embryonic root, and reveals that ground tissue initiation
and maintenance use different regulators and mechanisms. Moreover, our data provide
a framework for the simultaneous formation of multiple cell types by the same
transcriptional regulator.

text: Plants have the ability to continously generate new organs by maintaining
populations of stem cells throught their lives. The shoot apical meristem (SAM)
provides a stable environment for the maintenance of stem cells. All cells inside
the SAM divide, yet boundaries and patterns are maintained. Experimental evidence
indicates that patterning is independent of cell lineage, thus a dynamic self-regulatory
mechanism is required. A pivotal role in the organization of the SAM is played
by the WUSCHEL gene (WUS). An important question in this regard is that how WUS
expression is positioned in the SAM via a cell-lineage independent signaling mechanism.
In this study we demonstrate via mathematical modeling that a combination of an
inhibitor of the Cytokinin (CK) receptor, Arabidopsis histidine kinase 4 (AHK4)
and two morphogens originating from the top cell layer, can plausibly account
for the cell lineage-independent centering of WUS expression within SAM. Furthermore,
our laser ablation and microsurgical experiments support the hypothesis that patterning
in SAM occurs at the level of CK reception and signaling. The model suggests that
the interplay between CK signaling, WUS/CLV feedback loop and boundary signals
can account for positioning of the WUS expression, and provides directions for
further experimental investigation.

and Y. Deb for advice regarding the laser ablation experiments. We specially thank
Thomas Laux for stimulating discussions and support in the initial phase of this
project.

text: The visualization of hormonal signaling input and output is key to understanding
how multicellular development is regulated. The plant signaling molecule auxin
triggers many growth and developmental responses, but current tools lack the sensitivity
or precision to visualize these. We developed a set of fluorescent reporters that
allow sensitive and semiquantitative readout of auxin responses at cellular resolution
in Arabidopsis thaliana. These generic tools are suitable for any transformable
plant species.
