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 ...

grassy tillers1 promotes apical dominance in maize and responds to shade signals in the grasses [PDF]

, 2011
The shape of a plant is largely determined by regulation of lateral branching. Branching architecture can vary widely in response to both genotype and environment, suggesting regulation by a complex interaction of autonomous genetic factors and external ...

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.

Shade Avoidance and Neighbor Detection

, 2019
Plants detect neighboring vegetation as potential competitors for resources. Vegetation proximity is perceived by changes in the red (R) to far-red (FR) ratio (R:FR) through the phytochrome photoreceptors. To face this challenge, many plants have evolved the strategy to avoid shade, displaying a series of responses known as the shade avoidance syndrome

Auxin and Gibberellins Are Required for the Receptor-Like Kinase ERECTA Regulated Hypocotyl Elongation in Shade Avoidance in Arabidopsis

Frontiers in Plant Science, 2018
Plants use shade avoidance strategy to escape the canopy shade when grown under natural conditions. Previous studies showed that the Arabidopsis receptor-like kinase ERECTA (ER) is involved in shade avoidance syndrome.

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.

Shade-induced RTFL/DVL peptides negatively regulate the shade response by directly interacting with BSKs in Arabidopsis

Nature Communications, 2023
For shade-intolerant species, shade light indicates the close proximity of neighboring plants and triggers the shade avoidance syndrome (SAS), which causes exaggerated growth and reduced crop yield.

Integration of Phytochrome and Cryptochrome Signals Determines Plant Growth during Competition for Light. [PDF]

, 2016
Plants in dense vegetation perceive their neighbors primarily through changes in light quality. Initially, the ratio between red (R) and far-red (FR) light decreases due to reflection of FR by plant tissue well before shading occurs.

Incidence and public health burden of sunburn among beachgoers in the United States. [PDF]

, 2020
The beach environment creates many barriers to effective sun protection, putting beachgoers at risk for sunburn, a well-established risk factor for skin cancer.
