text: Reactive oxygen species (ROS) have been implicated in multiple signaling processes
in plants, but the underlying mechanisms and roles remain enigmatic. In this study,
we developed a method of live imaging of apoplastic ROS at the root surface. Distinct
signals, including auxin, extracellular adenosine triphosphate, and rapid alkalinization
factor 1 peptide, induce cytosolic calcium transients and apoplastic ROS bursts.
Genetic and optogenetic manipulations of Arabidopsis identified calcium transients
as necessary and sufficient for ROS bursts through activation of reduced nicotinamide
adenine dinucleotide phosphate (NADPH) oxidases RBOHC and RBOHF. Apoplastic ROS
bursts are not required, but they do limit gravity-induced root bending. Root
bending is sensed by the stretch-activated calcium channel MCA1, leading to NADPH
oxidase activation. The resulting ROS production stiffens cell walls to facilitate
soil penetration. Apoplastic ROS thus provides a means to balance tissue flexibility
and stiffness to navigate soil.

text: 'Super-resolution methods provide far better spatial resolution than the optical
diffraction limit of about half the wavelength of light (∼200-300 nm). Nevertheless,
they have yet to attain widespread use in plants, largely due to plants’ challenging
optical properties. Expansion microscopy improves effective resolution by isotropically
increasing the physical distances between sample structures while preserving relative
spatial arrangements and clearing the sample. However, its application to plants
has been hindered by the rigid, mechanically cohesive structure of plant tissues.
Here, we report on whole-mount expansion microscopy of thale cress (Arabidopsis
thaliana) root tissues (PlantEx), achieving a four-fold resolution increase over
conventional microscopy. Our results highlight the microtubule cytoskeleton organization
and interaction between molecularly defined cellular constituents. Combining PlantEx
with stimulated emission depletion (STED) microscopy, we increase nanoscale resolution
and visualize the complex organization of subcellular organelles from intact tissues
by example of the densely packed COPI-coated vesicles associated with the Golgi
apparatus and put these into a cellular structural context. Our results show that
expansion microscopy can be applied to increase effective imaging resolution in
Arabidopsis root specimens. '

text: Phytohormone auxin and its directional transport mediate much of the remarkably
plastic development of higher plants. Positive feedback between auxin signaling
and transport is a prerequisite for (1) self-organizing processes, including vascular
tissue formation, and (2) directional growth responses such as gravitropism. Here,
we identify a mechanism by which auxin signaling directly targets PIN auxin transporters.
Via the cell-surface AUXIN-BINDING PROTEIN1 (ABP1)-TRANSMEMBRANE KINASE 1 (TMK1)
receptor module, auxin rapidly induces phosphorylation and thus stabilization
of PIN2. Following gravistimulation, initial auxin asymmetry activates autophosphorylation
of the TMK1 kinase. This induces TMK1 interaction with and phosphorylation of
PIN2, stabilizing PIN2 at the lower root side, thus reinforcing asymmetric auxin
flow for root bending. Upstream of TMK1 in this regulation, ABP1 acts redundantly
with the root-expressed ABP1-LIKE 3 (ABL3) auxin receptor. Such positive feedback
between cell-surface auxin signaling and PIN-mediated polar auxin transport is
fundamental for robust root gravitropism and presumably for other self-organizing
developmental phenomena.

text: Phytohormone auxin and its directional transport mediate much of the remarkably
plastic development of higher plants. Positive feedback between auxin signaling
and transport is a key prerequisite for (i) self-organizing processes including
vascular tissue formation and (ii) directional growth responses such as gravitropism.
Here we identify a mechanism, by which auxin signaling directly targets PIN auxin
transporters. Via the cell-surface ABP1-TMK1 receptor module, auxin rapidly induces
phosphorylation and thus stabilization of PIN2. Following gravistimulation, initial
auxin asymmetry activates autophosphorylation of the TMK1 kinase. This induces
TMK1 interaction with and phosphorylation of PIN2, stabilizing PIN2 at the lower
root side, thus reinforcing asymmetric auxin flow for root bending. Upstream of
TMK1 in this regulation, ABP1 acts redundantly with the root-expressed ABP1-LIKE
auxin receptor ABL3. Such positive feedback between cell-surface auxin signaling
and PIN-mediated polar auxin transport is fundamental for robust root gravitropism
and presumably also for other self-organizing developmental phenomena.

- lang: eng
text: Clathrin-mediated endocytosis (CME) is an essential process of cargo uptake
operating in all eukaryotes. In animals and yeast, BAR-SH3 domain proteins, endophilins
and amphiphysins, function at the conclusion of CME to recruit factors for vesicle
scission and uncoating. Arabidopsis thaliana contains the BAR-SH3 domain proteins
SH3P1–SH3P3, but their role is poorly understood. Here, we identify SH3Ps as functional
homologs of endophilin/amphiphysin. SH3P1–SH3P3 bind to discrete foci at the plasma
membrane (PM), and SH3P2 recruits late to a subset of clathrin-coated pits. The
SH3P2 PM recruitment pattern is nearly identical to its interactor, a putative
uncoating factor, AUXILIN-LIKE1. Notably, SH3P1–SH3P3 are required for most of
AUXILIN-LIKE1 recruitment to the PM. This indicates a plant-specific modification
of CME, where BAR-SH3 proteins recruit auxilin-like uncoating factors rather than
the uncoating phosphatases, synaptojanins. SH3P1–SH3P3 act redundantly in overall
CME with the plant-specific endocytic adaptor TPLATE complex but not due to an
SH3 domain in its TASH3 subunit.

text: Multiplexed fluorescence microscopy imaging is widely used in biomedical applications.
However, simultaneous imaging of multiple fluorophores can result in spectral
leaks and overlapping, which greatly degrades image quality and subsequent analysis.
Existing popular spectral unmixing methods are mainly based on computational intensive
linear models and the performance is heavily dependent on the reference spectra,
which may greatly preclude its further applications. In this paper, we propose
a deep learning-based blindly spectral unmixing method, termed AutoUnmix, to imitate
the physical spectral mixing process. A tranfer learning framework is further
devised to allow our AutoUnmix adapting to a variety of imaging systems without
retraining the network. Our proposed method has demonstrated real-time unmixing
capabilities, surpassing existing methods by up to 100-fold in terms of unmixing
speed. We further validate the reconstruction performance on both synthetic datasets
and biological samples. The unmixing results of AutoUnmix achieve a highest SSIM
of 0.99 in both three- and four-color imaging, with nearly up to 20% higher than
other popular unmixing methods. Due to the desirable property of data independency
and superior blind unmixing performance, we believe AutoUnmix is a powerful tool
to study the interaction process of different organelles labeled by multiple fluorophores.

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.
