Selection‐mediated adaptive responses of native species to an invasive grass: Shade tolerance vs. shade avoidance

Functional Ecology
Studies suggesting that native plant species adapt to invasive species are accumulating, but we still have little evidence of native species performance recovery over time, following phenotypic selection by invaders. The following sequential evidence

TCP13 promotes shade avoidance syndrome-like responses by directly targeting a subset of shade-responsive gene promoters.

Journal of Experimental Botany, 2023
TCP13 belongs to a TCP subgroup implicated in the shade avoidance syndrome (SAS), but its exact role remains unclear. Here, we show TCP13 promotes the SAS-like response by enhancing hypocotyl elongation and suppressing flavonoid biosynthesis as a part of

Phytochrome‐interacting factors play shared and distinct roles in regulating shade avoidance responses in Populus trees

Plant, Cell and Environment
Plants adjust their growth and development in response to changing light caused by canopy shade. The molecular mechanisms underlying shade avoidance responses have been widely studied in Arabidopsis and annual crop species, yet the shade avoidance ...

Water shortage reduces PHYTOCHROME INTERACTING FACTOR 4, 5 and 3 expression and shade avoidance in Arabidopsis.

The Plant Journal
In agricultural crops, forests and grasslands, water deficit often occurs in the presence of cues from neighbouring vegetation. However, most studies have addressed separately the mechanisms of plant growth responses to these two aspects of the ...

The BBX7/8-CCA1/LHY transcription factor cascade promotes shade avoidance by activating PIF4.

New Phytologist
Sun-loving plants undergo shade avoidance syndrome (SAS) to compete with their neighbors for sunlight in shade conditions. Phytochrome B (phyB) plays a dominant role in sensing the shading signals (low red to far-red ratios) and triggering SAS.

Karrikin Signaling Regulates Hypocotyl Shade Avoidance Response by Modulating Auxin Homeostasis in Arabidopsis.

New Phytologist, 2022
Shade affects all aspects of plant growth and development, including seed germination, hypocotyl elongation, petiole growth, leaf hyponasty, and flowering time.

B-Box transcription factor BBX28 requires CONSTITUTIVE PHOTOMORPHOGENESIS1 to induce shade-avoidance response in Arabidopsis thaliana.

Plant Physiology
Shade avoidance syndrome is an important adaptive strategy. Under shade, major transcriptional rearrangements underlie the reallocation of resources to elongate vegetative structures and redefine the plant architecture to compete for photosynthesis ...

Sextuple knockouts of a highly conserved and coexpressed AUXIN/INDOLE-3-ACETIC ACID gene set confer shade avoidance-like responses in Arabidopsis.

Plant, Cell and Environment
AUXIN/INDOLE-3-ACETIC ACIDs are transcriptional repressors for auxin signalling. Aux/IAAs of Arabidopsis thaliana display some functional redundancy. The IAA3/SHY2 clade (IAA1, IAA2, IAA3 and IAA4) show strong sequence similarity, but no higher-order ...

GmCRY1s Modulate Gibberellin Metabolism to Regulate Soybean Shade Avoidance in Response to Reduced Blue Light.

Molecular Plant, 2020
Soybean as an important legume crop displays classic shade avoidance syndrome (SAS) including exaggerated stem elongation that leads to lodging and yield reduction under density farming conditions.
