text: To adapt to the diverse array of biotic and abiotic cues, plants have evolved
sophisticated mechanisms to sense changes in environmental conditions and modulate
their growth. Growth-promoting hormones and defence signalling fine tune plant
development antagonistically. During host-pathogen interactions, this defence-growth
trade-off is mediated by the counteractive effects of the defence hormone salicylic
acid (SA) and the growth hormone auxin. Here we revealed an underlying mechanism
of SA regulating auxin signalling by constraining the plasma membrane dynamics
of PIN2 auxin efflux transporter in Arabidopsis thaliana roots. The lateral diffusion
of PIN2 proteins is constrained by SA signalling, during which PIN2 proteins are
condensed into hyperclusters depending on REM1.2-mediated nanodomain compartmentalisation.
Furthermore, membrane nanodomain compartmentalisation by SA or Remorin (REM) assembly
significantly suppressed clathrin-mediated endocytosis. Consequently, SA-induced
heterogeneous surface condensation disrupted asymmetric auxin distribution and
the resultant gravitropic response. Our results demonstrated a defence-growth
trade-off mechanism by which SA signalling crosstalked with auxin transport by
concentrating membrane-resident PIN2 into heterogeneous compartments.

text: "• The phenylpropanoid pathway serves a central role in plant metabolism,
providing numerous compounds involved in diverse physiological processes. Most
carbon entering the pathway is incorporated into lignin. Although several phenylpropanoid
pathway mutants show seedling growth arrest, the role for lignin in seedling growth
and development is unexplored.\r\n• We use complementary pharmacological and genetic
approaches to block CINNAMATE‐4‐HYDROXYLASE (C4H) functionality in Arabidopsis
seedlings and a set of molecular and biochemical techniques to investigate the
underlying phenotypes.\r\n• Blocking C4H resulted in reduced lateral rooting and
increased adventitious rooting apically in the hypocotyl. These phenotypes coincided
with an inhibition in auxin transport. The upstream accumulation in cis‐cinnamic
acid was found to likely cause polar auxin transport inhibition. Conversely, a
downstream depletion in lignin perturbed phloem‐mediated auxin transport. Restoring
lignin deposition effectively reestablished phloem transport and, accordingly,
auxin homeostasis.\r\n• Our results show that the accumulation of bioactive intermediates
and depletion in lignin jointly cause the aberrant phenotypes upon blocking C4H,
and demonstrate that proper deposition of lignin is essential for the establishment
of auxin distribution in seedlings. Our data position the phenylpropanoid pathway
and lignin in a new physiological framework, consolidating their importance in
plant growth and development."

text: Tropisms, growth responses to environmental stimuli such as light or gravity,
are spectacular examples of adaptive plant development. The plant hormone auxin
serves as a major coordinative signal. The PIN auxin exporters, through their
dynamic polar subcellular localizations, redirect auxin fluxes in response to
environmental stimuli and the resulting auxin gradients across organs underly
differential cell elongation and bending. In this review, we discuss recent advances
concerning regulations of PIN polarity during tropisms, focusing on PIN phosphorylation
and trafficking. We also cover how environmental cues regulate PIN actions during
tropisms, and a crucial role of auxin feedback on PIN polarity during bending
termination. Finally, the interactions between different tropisms are reviewed
to understand plant adaptive growth in the natural environment.

text: "Plant survival depends on vascular tissues, which originate in a self‐organizing
manner as strands of cells co‐directionally transporting the plant hormone auxin.
The latter phenomenon (also known as auxin canalization) is classically hypothesized
to be regulated by auxin itself via the effect of this hormone on the polarity
of its own intercellular transport. Correlative observations supported this concept,
but molecular insights remain limited.\r\nIn the current study, we established
an experimental system based on the model Arabidopsis thaliana, which exhibits
auxin transport channels and formation of vasculature strands in response to local
auxin application.\r\nOur methodology permits the genetic analysis of auxin canalization
under controllable experimental conditions. By utilizing this opportunity, we
confirmed the dependence of auxin canalization on a PIN‐dependent auxin transport
and nuclear, TIR1/AFB‐mediated auxin signaling. We also show that leaf venation
and auxin‐mediated PIN repolarization in the root require TIR1/AFB signaling.\r\nFurther
studies based on this experimental system are likely to yield better understanding
of the mechanisms underlying auxin transport polarization in other developmental
contexts."

text: "Root gravitropism is one of the most important processes allowing plant adaptation
to the land environment. Auxin plays a central role in mediating root gravitropism,
but how auxin contributes to gravitational perception and the subsequent response
is still unclear.\r\n\r\nHere, we showed that the local auxin maximum/gradient
within the root apex, which is generated by the PIN directional auxin transporters,
regulates the expression of three key starch granule synthesis genes, SS4, PGM
and ADG1, which in turn influence the accumulation of starch granules that serve
as a statolith perceiving gravity.\r\n\r\nMoreover, using the cvxIAA‐ccvTIR1 system,
we also showed that TIR1‐mediated auxin signaling is required for starch granule
formation and gravitropic response within root tips. In addition, axr3 mutants
showed reduced auxin‐mediated starch granule accumulation and disruption of gravitropism
within the root apex.\r\n\r\nOur results indicate that auxin‐mediated statolith
production relies on the TIR1/AFB‐AXR3‐mediated auxin signaling pathway. In summary,
we propose a dual role for auxin in gravitropism: the regulation of both gravity
perception and response."
