Interactions between auxin, microtubules and XTHs mediate green shade- induced petiole elongation in arabidopsis.

PLoS ONE, 2014
Plants are highly attuned to translating environmental changes to appropriate modifications in growth. Such phenotypic plasticity is observed in dense vegetations, where shading by neighboring plants, triggers rapid unidirectional shoot growth (shade ...

Phytochrome A elevates plant circadian-clock components to suppress shade avoidance in deep-canopy shade. [PDF]

Proc Natl Acad Sci U S A, 2021
Significance Plants can detect the proximity and density of neighboring vegetation using phytochrome photoreceptors. In shade-sensitive species, canopy cover drives stem elongation, facilitating light foraging. In deep shade, where resources are severely

SALT OVERLY SENSITIVE2 stabilizes phytochrome-interacting factors PIF4 and PIF5 to promote Arabidopsis shade avoidance.

The Plant Cell, 2023
Sun-loving plants trigger the shade avoidance syndrome (SAS) to compete against their neighbors for sunlight. Phytochromes are plant red (R) and far-red (FR) light photoreceptors that play a major role in perceiving the shading signals and triggering SAS.

The shade avoidance syndrome in Arabidopsis: the antagonistic role of phytochrome a and B differentiates vegetation proximity and canopy shade. [PDF]

PLoS ONE, 2014
Light limitation caused by dense vegetation is one of the greatest threats to plant survival in natural environments. Plants detect such neighboring vegetation as a reduction in the red to far-red ratio (R:FR) of the incoming light.

Understanding the Shade Tolerance Responses Through Hints From Phytochrome A-Mediated Negative Feedback Regulation in Shade Avoiding Plants

Frontiers in Plant Science, 2021
Based on how plants respond to shade, we typically classify them into two groups: shade avoiding and shade tolerance plants. Under vegetative shade, the shade avoiding species induce a series of shade avoidance responses (SARs) to outgrow their ...

UVR8 disrupts stabilisation of PIF5 by COP1 to inhibit plant stem elongation in sunlight

Nature Communications, 2019
UV-B light suppresses the shade avoidance response in plants by reducing the abundance of PIF transcription factors by an undefined mechanism. Here the authors show that UV-B perceived by the UVR8 receptor inhibits the shade avoidance response by ...

Tomato phyE is Required for Shade Avoidance in the Absence of phyB1 and phyB2.

Frontiers in Plant Science, 2016
The phytochrome (phy) family of red and far-red photoreceptors provides plants with critical information about their surrounding environment and can signal downstream developmental and physiological changes.

A combination of plasma membrane sterol biosynthesis and autophagy is required for shade-induced hypocotyl elongation

Nature Communications, 2022
Plants subject to vegetative shade receive a low quantity of blue light (LB) and a low ratio of red to far-red light (LFLR). Here the authors show that while LB induces autophagy, LFLR leads to changes in lipid metabolism, and propose that these ...

Multiple Loci Control Variation in Plasticity to Foliar Shade Throughout Development in Arabidopsis thaliana

G3: Genes, Genomes, Genetics, 2020
The shade avoidance response is a set of developmental changes exhibited by plants to avoid shading by competitors, and is an important model of adaptive plant plasticity.

Survey on heat avoidance behaviors of pedestrians waiting at traffic signals at intersections

City and Environment Interactions
The implementation of urban heat-mitigation measures, such as sunshades, mist spraying, cool pavements, street trees, and wall greening, is known to be effective in mitigating the thermal environment in outdoor spaces.
