text: The plant-signaling molecule auxin triggers fast and slow cellular responses
across land plants and algae. The nuclear auxin pathway mediates gene expression
and controls growth and development in land plants, but this pathway is absent
from algal sister groups. Several components of rapid responses have been identified
in Arabidopsis, but it is unknown if these are part of a conserved mechanism.
We recently identified a fast, proteome-wide phosphorylation response to auxin.
Here, we show that this response occurs across 5 land plant and algal species
and converges on a core group of shared targets. We found conserved rapid physiological
responses to auxin in the same species and identified rapidly accelerated fibrosarcoma
(RAF)-like protein kinases as central mediators of auxin-triggered phosphorylation
across species. Genetic analysis connects this kinase to both auxin-triggered
protein phosphorylation and rapid cellular response, thus identifying an ancient
mechanism for fast auxin responses in the green lineage.

text: Much of plant development depends on cell-to-cell redistribution of the plant
hormone auxin, which is facilitated by the plasma membrane (PM) localized PIN
FORMED (PIN) proteins. Auxin export activity, developmental roles, subcellular
trafficking, and polarity of PINs have been well studied, but their structure
remains elusive besides a rough outline that they contain two groups of 5 alpha-helices
connected by a large hydrophilic loop (HL). Here, we focus on the PIN1 HL as we
could produce it in sufficient quantities for biochemical investigations to provide
insights into its secondary structure. Circular dichroism (CD) studies revealed
its nature as an intrinsically disordered protein (IDP), manifested by the increase
of structure content upon thermal melting. Consistent with IDPs serving as interaction
platforms, PIN1 loops homodimerize. PIN1 HL cytoplasmic overexpression in Arabidopsis
disrupts early endocytic trafficking of PIN1 and PIN2 and causes defects in the
cotyledon vasculature formation. In summary, we demonstrate that PIN1 HL has an
intrinsically disordered nature, which must be considered to gain further structural
insights. Some secondary structures may form transiently during pairing with known
and yet-to-be-discovered interactors.

text: Strigolactones (SLs) are a class of phytohormones that regulate plant shoot
branching and adventitious root development. However, little is known regarding
the role of SLs in controlling the behavior of the smallest unit of the organism,
the single cell. Here, taking advantage of a classic single-cell model offered
by the cotton (Gossypium hirsutum) fiber cell, we show that SLs, whose biosynthesis
is fine-tuned by gibberellins (GAs), positively regulate cell elongation and cell
wall thickness by promoting the biosynthesis of very-long-chain fatty acids (VLCFAs)
and cellulose, respectively. Furthermore, we identified two layers of transcription
factors (TFs) involved in the hierarchical regulation of this GA-SL crosstalk.
The top-layer TF GROWTH-REGULATING FACTOR 4 (GhGRF4) directly activates expression
of the SL biosynthetic gene DWARF27 (D27) to increase SL accumulation in fiber
cells and GAs induce GhGRF4 expression. SLs induce the expression of four second-layer
TF genes (GhNAC100-2, GhBLH51, GhGT2, and GhB9SHZ1), which transmit SL signals
downstream to two ketoacyl-CoA synthase genes (KCS) and three cellulose synthase
(CesA) genes by directly activating their transcription. Finally, the KCS and
CesA enzymes catalyze the biosynthesis of very long chain fatty acids and cellulose,
respectively, to regulate development of high-grade cotton fibers. In addition
to providing a theoretical basis for cotton fiber improvement, our results shed
light on SL signaling in plant development at the single-cell level.

text: The phytohormone auxin triggers transcriptional reprogramming through a well-characterized
perception machinery in the nucleus. By contrast, mechanisms that underlie fast
effects of auxin, such as the regulation of ion fluxes, rapid phosphorylation
of proteins or auxin feedback on its transport, remain unclear1,2,3. Whether auxin-binding
protein 1 (ABP1) is an auxin receptor has been a source of debate for decades1,4.
Here we show that a fraction of Arabidopsis thaliana ABP1 is secreted and binds
auxin specifically at an acidic pH that is typical of the apoplast. ABP1 and its
plasma-membrane-localized partner, transmembrane kinase 1 (TMK1), are required
for the auxin-induced ultrafast global phospho-response and for downstream processes
that include the activation of H+-ATPase and accelerated cytoplasmic streaming.
abp1 and tmk mutants cannot establish auxin-transporting channels and show defective
auxin-induced vasculature formation and regeneration. An ABP1(M2X) variant that
lacks the capacity to bind auxin is unable to complement these defects in abp1
mutants. These data indicate that ABP1 is the auxin receptor for TMK1-based cell-surface
signalling, which mediates the global phospho-response and auxin canalization.

text: "Blood – this is what animals use to heal wounds fast and efficient. Plants
do not have blood circulation and their cells cannot move. However, plants have
evolved remarkable capacities to regenerate tissues and organs preventing further
damage. In my PhD research, I studied the wound healing in the Arabidopsis root.
I used a UV laser to ablate single cells in the root tip and observed the consequent
wound healing. Interestingly, the inner adjacent cells induced a\r\ndivision plane
switch and subsequently adopted the cell type of the killed cell to replace it.
We termed this form of wound healing “restorative divisions”. This initial observation
triggered the questions of my PhD studies: How and why do cells orient their division
planes, how do they feel the wound and why does this happen only in inner adjacent
cells.\r\nFor answering these questions, I used a quite simple experimental setup:
5 day - old seedlings were stained with propidium iodide to visualize cell walls
and dead cells; ablation was carried out using a special laser cutter and a confocal
microscope. Adaptation of the novel vertical microscope system made it possible
to observe wounds in real time. This revealed that restorative divisions occur
at increased frequency compared to normal divisions. Additionally,\r\nthe major
plant hormone auxin accumulates in wound adjacent cells and drives the expression
of the wound-stress responsive transcription factor ERF115. Using this as a marker
gene for wound responses, we found that an important part of wound signalling
is the sensing of the collapse of the ablated cell. The collapse causes a radical
pressure drop, which results in strong tissue deformations. These deformations
manifest in an invasion of the now free spot specifically by the inner adjacent
cells within seconds, probably because of higher pressure of the inner tissues.
Long-term imaging revealed that those deformed cells continuously expand towards
the wound hole and that this is crucial for the restorative division. These wound-expanding
cells exhibit an abnormal, biphasic polarity of microtubule arrays\r\nbefore the
division. Experiments inhibiting cell expansion suggest that it is the biphasic
stretching that induces those MT arrays. Adapting the micromanipulator aspiration
system from animal scientists at our institute confirmed the hypothesis that stretching
influences microtubule stability. In conclusion, this shows that microtubules
react to tissue deformation\r\nand this facilitates the observed division plane
switch. This puts mechanical cues and tensions at the most prominent position
for explaining the growth and wound healing properties of plants. Hence, it shines
light onto the importance of understanding mechanical signal transduction. "

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.
