text: The primary cell wall is a fundamental plant constituent that is flexible
but sufficiently rigid to support the plant cell shape. Although many studies
have demonstrated that reactive oxygen species (ROS) serve as important signaling
messengers to modify the cell wall structure and affect cellular growth, the regulatory
mechanism underlying the spatial-temporal regulation of ROS activity for cell
wall maintenance remains largely unclear. Here, we demonstrate the role of the
Arabidopsis (Arabidopsis thaliana) multicopper oxidase-like protein skewed 5 (SKU5)
and its homolog SKU5-similar 1 (SKS1) in root cell wall formation through modulating
ROS homeostasis. Loss of SKU5 and SKS1 function resulted in aberrant division
planes, protruding cell walls, ectopic deposition of iron, and reduced nicotinamide
adeninedinucleotide phosphate (NADPH) oxidase-dependent ROS overproduction in
the root epidermis–cortex and cortex–endodermis junctions. A decrease in ROS level
or inhibition of NADPH oxidase activity rescued the cell wall defects of sku5
sks1 double mutants. SKU5 and SKS1 proteins were activated by iron treatment,
and iron over-accumulated in the walls between the root epidermis and cortex cell
layers of sku5 sks1. The glycosylphosphatidylinositol-anchored motif was crucial
for membrane association and functionality of SKU5 and SKS1. Overall, our results
identified SKU5 and SKS1 as regulators of ROS at the cell surface for regulation
of cell wall structure and root cell growth.

text: The 3′,5′-cyclic adenosine monophosphate (cAMP) is a versatile second messenger
in many mammalian signaling pathways. However, its role in plants remains not
well-recognized. Recent discovery of adenylate cyclase (AC) activity for transport
inhibitor response 1/auxin-signaling F-box proteins (TIR1/AFB) auxin receptors
and the demonstration of its importance for canonical auxin signaling put plant
cAMP research back into spotlight. This insight briefly summarizes the well-established
cAMP signaling pathways in mammalian cells and describes the turbulent and controversial
history of plant cAMP research highlighting the major progress and the unresolved
points. We also briefly review the current paradigm of auxin signaling to provide
a background for the discussion on the AC activity of TIR1/AFB auxin receptors
and its potential role in transcriptional auxin signaling as well as impact of
these discoveries on plant cAMP research in general.

text: Soluble chaperones residing in the endoplasmic reticulum (ER) play vitally
important roles in folding and quality control of newly synthesized proteins that
transiently pass through the ER en route to their final destinations. These soluble
residents of the ER are themselves endowed with an ER retrieval signal that enables
the cell to bring the escaped residents back from the Golgi. Here, by using purified
proteins, we showed that Nicotiana tabacum phytaspase, a plant aspartate-specific
protease, introduces two breaks at the C-terminus of the N. tabacum ER resident
calreticulin-3. These cleavages resulted in removal of either a dipeptide or a
hexapeptide from the C-terminus of calreticulin-3 encompassing part or all of
the ER retrieval signal. Consistently, expression of the calreticulin-3 derivative
mimicking the phytaspase cleavage product in Nicotiana benthamiana cells demonstrated
loss of the ER accumulation of the protein. Notably, upon its escape from the
ER, calreticulin-3 was further processed by an unknown protease(s) to generate
the free N-terminal (N) domain of calreticulin-3, which was ultimately secreted
into the apoplast. Our study thus identified a specific proteolytic enzyme capable
of precise detachment of the ER retrieval signal from a plant ER resident protein,
with implications for the further fate of the escaped resident.

text: Auxin is the major plant hormone regulating growth and development (Friml,
2022). Forward genetic approaches in the model plant Arabidopsis thaliana have
identified major components of auxin signalling and established the canonical
mechanism mediating transcriptional and thus developmental reprogramming. In this
textbook view, TRANSPORT INHIBITOR RESPONSE 1 (TIR1)/AUXIN-SIGNALING F-BOX (AFBs)
are auxin receptors, which act as F-box subunits determining the substrate specificity
of the Skp1-Cullin1-F box protein (SCF) type E3 ubiquitin ligase complex. Auxin
acts as a “molecular glue” increasing the affinity between TIR1/AFBs and the Aux/IAA
repressors. Subsequently, Aux/IAAs are ubiquitinated and degraded, thus releasing
auxin transcription factors from their repression making them free to mediate
transcription of auxin response genes (Yu et al., 2022). Nonetheless, accumulating
evidence suggests existence of rapid, non-transcriptional responses downstream
of TIR1/AFBs such as auxin-induced cytosolic calcium (Ca2+) transients, plasma
membrane depolarization and apoplast alkalinisation, all converging on the process
of root growth inhibition and root gravitropism (Li et al., 2022). Particularly,
these rapid responses are mostly contributed by predominantly cytosolic AFB1,
while the long-term growth responses are mediated by mainly nuclear TIR1 and AFB2-AFB5
(Li et al., 2021; Prigge et al., 2020; Serre et al., 2021). How AFB1 conducts
auxin-triggered rapid responses and how it is different from TIR1 and AFB2-AFB5
remains elusive. Here, we compare the roles of TIR1 and AFB1 in transcriptional
and rapid responses by modulating their subcellular localization in Arabidopsis
and by testing their ability to mediate transcriptional responses when part of
the minimal auxin circuit reconstituted in yeast.

text: As a crucial nitrogen source, nitrate (NO3−) is a key nutrient for plants.
Accordingly, root systems adapt to maximize NO3− availability, a developmental
regulation also involving the phytohormone auxin. Nonetheless, the molecular mechanisms
underlying this regulation remain poorly understood. Here, we identify low-nitrate-resistant
mutant (lonr) in Arabidopsis (Arabidopsis thaliana), whose root growth fails to
adapt to low-NO3− conditions. lonr2 is defective in the high-affinity NO3− transporter
NRT2.1. lonr2 (nrt2.1) mutants exhibit defects in polar auxin transport, and their
low-NO3−-induced root phenotype depends on the PIN7 auxin exporter activity. NRT2.1
directly associates with PIN7 and antagonizes PIN7-mediated auxin efflux depending
on NO3− levels. These results reveal a mechanism by which NRT2.1 in response to
NO3− limitation directly regulates auxin transport activity and, thus, root growth.
This adaptive mechanism contributes to the root developmental plasticity to help
plants cope with changes in NO3− availability.

text: "Clathrin-mediated endocytosis (CME) is vital for the regulation of plant
growth and\r\ndevelopment by controlling plasma membrane protein composition and
cargo uptake. CME\r\nrelies on the precise recruitment control of protein regulators
for vesicle maturation and\r\nrelease. During the early stages of endocytosis,
an area of flat membrane is remodelled by\r\nproteins to create a spherical vesicle
against intracellular forces. After the Clathrin-coated\r\nvesicle (CCV) is fully
formed, scission machinery releases it from the plasma membrane,\r\nand cargo
proceeds for recycling or degradation through early endosomes / Trans Golgi\r\nnetwork.
Protein machineries that mediate membrane bending and vesicle release in plants\r\nare
unknown. However, studies show, that plant endocytosis is actin independent, thus\r\nindicating
that plants utilize a unique mechanism to mediate membrane bending against highturgor
pressure compared to other model systems. First, by using biochemical and advanced\r\nlive
microscopy approaches we investigate the TPLATE complex, a plant-specific\r\nendocytosis
protein complex. We found that TPLATE is peripherally associated with\r\nclathrin-coated
vesicles and localises at the rim of endocytosis events. Next, our study of\r\nplant
Dynamin-related protein 1C (DRP1C), which was hypothesised previously to play
a\r\nrole in vesicle release, shows the recruitment of the protein already at
the early stages of\r\nendocytosis. Moreover, DRP1C assembles into organised ring-like
structures and is able to\r\ninduce membrane deformation and tubulation, suggesting
its role also in membrane bending\r\nduring early CME. Based on the data from
mammalian and yeast systems, plant DynaminRelated Proteins 2 and SH3P2 protein
are strong candidates to be part of the plant vesicle\r\nscission machinery; however,
their precise role in plant CME has not been yet elucidated.\r\nHere, we characterised
DRP2s and SH3P2 roles in CME by combining high-resolution\r\nimaging of endocytic
events in vivo and protein characterisation. Although DRP2s and\r\nSH3P2 arrive
together during late CME and physically interact, genetic analysis using\r\n∆sh3p1,2,3
mutant and complementation with non-DRP2-interacting SH3P2 variants suggest\r\nthat
SH3P2 does not directly recruit DRP2s to the site of endocytosis. Summarising
our\r\nresearch, these observations provide new important insights into the mechanism
of plant\r\nCME and show that, despite plants posses many homologues of mammalian
and yeast CME\r\ncomponents, they do not necessarily act in the same manner. "

text: Clathrin-mediated endocytosis (CME) is vital for the regulation of plant growth
and development by controlling plasma membrane protein composition and cargo uptake.
CME relies on the precise recruitment of regulators for vesicle maturation and
release. Homologues of components of mammalian vesicle scission are strong candidates
to be part of the scissin machinery in plants, but the precise roles of these
proteins in this process is not fully understood. Here, we characterised the roles
of Plant Dynamin-Related Proteins 2 (DRP2s) and SH3-domain containing protein
2 (SH3P2), the plant homologue to Dynamins’ recruiters, like Endophilin and Amphiphysin,
in the CME by combining high-resolution imaging of endocytic events in vivo and
characterisation of the purified proteins in vitro. Although DRP2s and SH3P2 arrive
similarly late during CME and physically interact, genetic analysis of the Dsh3p1,2,3
triple-mutant and complementation assays with non-SH3P2-interacting DRP2 variants
suggests that SH3P2 does not directly recruit DRP2s to the site of endocytosis.
These observations imply that despite the presence of many well-conserved endocytic
components, plants have acquired a distinct mechanism for CME. One Sentence Summary
In contrast to predictions based on mammalian systems, plant Dynamin-related proteins
2 are recruited to the site of Clathrin-mediated endocytosis independently of
BAR-SH3 proteins.

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: Calcium-dependent protein kinases (CPK) are key components of a wide array
of signaling pathways, translating stress and nutrient signaling into the modulation
of cellular processes such as ion transport and transcription. However, not much
is known about CPKs in endomembrane trafficking. Here, we screened for CPKs that
impact on root growth and gravitropism, by overexpressing constitutively active
forms of CPKs under the control of an inducible promoter in Arabidopsis thaliana.
We found that inducible overexpression of an constitutive active CPK30 (CA-CPK30)
resulted in a loss of root gravitropism and ectopic auxin accumulation in the
root tip. Immunolocalization revealed that CA-CPK30 roots have reduced PIN protein
levels, PIN1 polarity defects and impaired Brefeldin A (BFA)-sensitive trafficking.
Moreover, FM4-64 uptake was reduced, indicative of a defect in endocytosis. The
effects on BFA-sensitive trafficking were not specific to PINs, as BFA could not
induce aggregation of ARF1- and CHC-labeled endosomes in CA-CPK30. Interestingly,
the interference with BFA-body formation, could be reverted by increasing the
extracellular pH, indicating a pH-dependence of this CA-CPK30 effect. Altogether,
our data reveal an important role for CPK30 in root growth regulation and endomembrane
trafficking in Arabidopsis thaliana.

text: Plant cell growth responds rapidly to various stimuli, adapting architecture
to environmental changes. Two major endogenous signals regulating growth are the
phytohormone auxin and the secreted peptides rapid alkalinization factors (RALFs).
Both trigger very rapid cellular responses and also exert long-term effects [Du
et al., Annu. Rev. Plant Biol. 71, 379–402 (2020); Blackburn et al., Plant Physiol.
182, 1657–1666 (2020)]. However, the way, in which these distinct signaling pathways
converge to regulate growth, remains unknown. Here, using vertical confocal microscopy
combined with a microfluidic chip, we addressed the mechanism of RALF action on
growth. We observed correlation between RALF1-induced rapid Arabidopsis thaliana
root growth inhibition and apoplast alkalinization during the initial phase of
the response, and revealed that RALF1 reversibly inhibits primary root growth
through apoplast alkalinization faster than within 1 min. This rapid apoplast
alkalinization was the result of RALF1-induced net H+ influx and was mediated
by the receptor FERONIA (FER). Furthermore, we investigated the cross-talk between
RALF1 and the auxin signaling pathways during root growth regulation. The results
showed that RALF-FER signaling triggered auxin signaling with a delay of approximately
1 h by up-regulating auxin biosynthesis, thus contributing to sustained RALF1-induced
growth inhibition. This biphasic RALF1 action on growth allows plants to respond
rapidly to environmental stimuli and also reprogram growth and development in
the long term.

text: Directionality in the intercellular transport of the plant hormone auxin is
determined by polar plasma membrane localization of PIN-FORMED (PIN) auxin transport
proteins. However, apart from PIN phosphorylation at conserved motifs, no further
determinants explicitly controlling polar PIN sorting decisions have been identified.
Here we present Arabidopsis WAVY GROWTH 3 (WAV3) and closely related RING-finger
E3 ubiquitin ligases, whose loss-of-function mutants show a striking apical-to-basal
polarity switch in PIN2 localization in root meristem cells. WAV3 E3 ligases function
as essential determinants for PIN polarity, acting independently from PINOID/WAG-dependent
PIN phosphorylation. They antagonize ectopic deposition of de novo synthesized
PIN proteins already immediately following completion of cell division, presumably
via preventing PIN sorting into basal, ARF GEF-mediated trafficking. Our findings
reveal an involvement of E3 ligases in the selective targeting of apically localized
PINs in higher plants.

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: 'Polar auxin transport is unique to plants and coordinates their growth and
development1,2. The PIN-FORMED (PIN) auxin transporters exhibit highly asymmetrical
localizations at the plasma membrane and drive polar auxin transport3,4; however,
their structures and transport mechanisms remain largely unknown. Here, we report
three inward-facing conformation structures of Arabidopsis thaliana PIN1: the
apo state, bound to the natural auxin indole-3-acetic acid (IAA), and in complex
with the polar auxin transport inhibitor N-1-naphthylphthalamic acid (NPA). The
transmembrane domain of PIN1 shares a conserved NhaA fold5. In the substrate-bound
structure, IAA is coordinated by both hydrophobic stacking and hydrogen bonding.
NPA competes with IAA for the same site at the intracellular pocket, but with
a much higher affinity. These findings inform our understanding of the substrate
recognition and transport mechanisms of PINs and set up a framework for future
research on directional auxin transport, one of the most crucial processes underlying
plant development.'

text: Plant root architecture flexibly adapts to changing nitrate (NO3−) availability
in the soil; however, the underlying molecular mechanism of this adaptive development
remains under-studied. To explore the regulation of NO3−-mediated root growth,
we screened for low-nitrate-resistant mutant (lonr) and identified mutants that
were defective in the NAC transcription factor NAC075 (lonr1) as being less sensitive
to low NO3− in terms of primary root growth. We show that NAC075 is a mobile transcription
factor relocating from the root stele tissues to the endodermis based on NO3−
availability. Under low-NO3− availability, the kinase CBL-interacting protein
kinase 1 (CIPK1) is activated, and it phosphorylates NAC075, restricting its movement
from the stele, which leads to the transcriptional regulation of downstream target
WRKY53, consequently leading to adapted root architecture. Our work thus identifies
an adaptive mechanism involving translocation of transcription factor based on
nutrient availability and leading to cell-specific reprogramming of plant root
growth.

text: Autophagosomes are double-membraned vesicles that traffic harmful or unwanted
cellular macromolecules to the vacuole for recycling. Although autophagosome biogenesis
has been extensively studied, autophagosome maturation, i.e., delivery and fusion
with the vacuole, remains largely unknown in plants. Here, we have identified
an autophagy adaptor, CFS1, that directly interacts with the autophagosome marker
ATG8 and localizes on both membranes of the autophagosome. Autophagosomes form
normally in Arabidopsis thaliana cfs1 mutants, but their delivery to the vacuole
is disrupted. CFS1’s function is evolutionarily conserved in plants, as it also
localizes to the autophagosomes and plays a role in autophagic flux in the liverwort
Marchantia polymorpha. CFS1 regulates autophagic flux by bridging autophagosomes
with the multivesicular body-localized ESCRT-I component VPS23A, leading to the
formation of amphisomes. Similar to CFS1-ATG8 interaction, disrupting the CFS1-VPS23A
interaction blocks autophagic flux and renders plants sensitive to nitrogen starvation.
Altogether, our results reveal a conserved vacuolar sorting hub that regulates
autophagic flux in plants.

text: Germline determination is essential for species survival and evolution in
multicellular organisms. In most flowering plants, formation of the female germline
is initiated with specification of one megaspore mother cell (MMC) in each ovule;
however, the molecular mechanism underlying this key event remains unclear. Here
we report that spatially restricted auxin signaling promotes MMC fate in Arabidopsis.
Our results show that the microRNA160 (miR160) targeted gene ARF17 (AUXIN RESPONSE
FACTOR17) is required for promoting MMC specification by genetically interacting
with the SPL/NZZ (SPOROCYTELESS/NOZZLE) gene. Alterations of auxin signaling cause
formation of supernumerary MMCs in an ARF17- and SPL/NZZ-dependent manner. Furthermore,
miR160 and ARF17 are indispensable for attaining a normal auxin maximum at the
ovule apex via modulating the expression domain of PIN1 (PIN-FORMED1) auxin transporter.
Our findings elucidate the mechanism by which auxin signaling promotes the acquisition
of female germline cell fate in plants.

text: The phytohormone auxin is the major coordinative signal in plant development1,
mediating transcriptional reprogramming by a well-established canonical signalling
pathway. TRANSPORT INHIBITOR RESPONSE 1 (TIR1)/AUXIN-SIGNALING F-BOX (AFB) auxin
receptors are F-box subunits of ubiquitin ligase complexes. In response to auxin,
they associate with Aux/IAA transcriptional repressors and target them for degradation
via ubiquitination2,3. Here we identify adenylate cyclase (AC) activity as an
additional function of TIR1/AFB receptors across land plants. Auxin, together
with Aux/IAAs, stimulates cAMP production. Three separate mutations in the AC
motif of the TIR1 C-terminal region, all of which abolish the AC activity, each
render TIR1 ineffective in mediating gravitropism and sustained auxin-induced
root growth inhibition, and also affect auxin-induced transcriptional regulation.
These results highlight the importance of TIR1/AFB AC activity in canonical auxin
signalling. They also identify a unique phytohormone receptor cassette combining
F-box and AC motifs, and the role of cAMP as a second messenger in plants.

text: Biological systems are the sum of their dynamic three-dimensional (3D) parts.
Therefore, it is critical to study biological structures in 3D and at high resolution
to gain insights into their physiological functions. Electron microscopy of metal
replicas of unroofed cells and isolated organelles has been a key technique to
visualize intracellular structures at nanometer resolution. However, many of these
methods require specialized equipment and personnel to complete them. Here, we
present novel accessible methods to analyze biological structures in unroofed
cells and biochemically isolated organelles in 3D and at nanometer resolution,
focusing on Arabidopsis clathrin-coated vesicles (CCVs). While CCVs are essential
trafficking organelles, their detailed structural information is lacking due to
their poor preservation when observed via classical electron microscopy protocols
experiments. First, we establish a method to visualize CCVs in unroofed cells
using scanning transmission electron microscopy tomography, providing sufficient
resolution to define the clathrin coat arrangements. Critically, the samples are
prepared directly on electron microscopy grids, removing the requirement to use
extremely corrosive acids, thereby enabling the use of this method in any electron
microscopy lab. Secondly, we demonstrate that this standardized sample preparation
allows the direct comparison of isolated CCV samples with those visualized in
cells. Finally, to facilitate the high-throughput and robust screening of metal
replicated samples, we provide a deep learning analysis method to screen the “pseudo
3D” morphologies of CCVs imaged with 2D modalities. Collectively, our work establishes
accessible ways to examine the 3D structure of biological samples and provide
novel insights into the structure of plant CCVs.

text: Ustilago maydis is a biotrophic phytopathogenic fungus that causes corn smut
disease. As a well-established model system, U. maydis is genetically fully accessible
with large omics datasets available and subject to various biological questions
ranging from DNA-repair, RNA-transport, and protein secretion to disease biology.
For many genetic approaches, tight control of transgene regulation is important.
Here we established an optimised version of the Tetracycline-ON (TetON) system
for U. maydis. We demonstrate the Tetracycline concentration-dependent expression
of fluorescent protein transgenes and the system’s suitability for the induced
expression of the toxic protein BCL2 Associated X-1 (Bax1). The Golden Gate compatible
vector system contains a native minimal promoter from the mating factor a-1 encoding
gene, mfa with ten copies of the tet-regulated operator (tetO) and a codon optimised
Tet-repressor (tetR*) which is translationally fused to the native transcriptional
corepressor Mql1 (UMAG_05501). The metabolism-independent transcriptional regulator
system is functional both, in liquid culture as well as on solid media in the
presence of the inducer and can become a useful tool for toxin-antitoxin studies,
identification of antifungal proteins, and to study functions of toxic gene products
in Ustilago maydis.

text: The synthetic strigolactone (SL) analog, rac-GR24, has been instrumental in
studying the role of SLs as well as karrikins because it activates the receptors
DWARF14 (D14) and KARRIKIN INSENSITIVE 2 (KAI2) of their signaling pathways, respectively.
Treatment with rac-GR24 modifies the root architecture at different levels, such
as decreasing the lateral root density (LRD), while promoting root hair elongation
or flavonol accumulation. Previously, we have shown that the flavonol biosynthesis
is transcriptionally activated in the root by rac-GR24 treatment, but, thus far,
the molecular players involved in that response have remained unknown. To get
an in-depth insight into the changes that occur after the compound is perceived
by the roots, we compared the root transcriptomes of the wild type and the more
axillary growth2 (max2) mutant, affected in both SL and karrikin signaling pathways,
with and without rac-GR24 treatment. Quantitative reverse transcription (qRT)-PCR,
reporter line analysis and mutant phenotyping indicated that the flavonol response
and the root hair elongation are controlled by the ELONGATED HYPOCOTYL 5 (HY5)
and MYB12 transcription factors, but HY5, in contrast to MYB12, affects the LRD
as well. Furthermore, we identified the transcription factors TARGET OF MONOPTEROS
5 (TMO5) and TMO5 LIKE1 as negative and the Mediator complex as positive regulators
of the rac-GR24 effect on LRD. Altogether, hereby, we get closer toward understanding
the molecular mechanisms that underlay the rac-GR24 responses in the root.
