Reducing shade avoidance responses in a cereal crop. [PDF]

AoB Plants, 2017
Several researchers have hypothesized that shade avoidance behaviour is favoured by natural selection because it increases the fitness of individuals. Shade avoidance can be disadvantageous for crops, however, because it reduces allocation of resources to reproductive yield, increases the risk of lodging and reduces weed suppression.

Shade avoidance components and pathways in adult plants revealed by phenotypic profiling. [PDF]

PLoS Genetics, 2015
Shade from neighboring plants limits light for photosynthesis; as a consequence, plants have a variety of strategies to avoid canopy shade and compete with their neighbors for light. Collectively the response to foliar shade is called the shade avoidance

YUCCA auxin biosynthetic genes are required for Arabidopsis shade avoidance [PDF]

PeerJ, 2016
Plants respond to neighbor shade by increasing stem and petiole elongation. Shade, sensed by phytochrome photoreceptors, causes stabilization of PHYTOCHROME INTERACTING FACTOR proteins and subsequent induction of YUCCA auxin biosynthetic genes.

A genome-wide association study identifies variants underlying the Arabidopsis thaliana shade avoidance response. [PDF]

PLoS Genetics, 2012
Shade avoidance is an ecologically and molecularly well-understood set of plant developmental responses that occur when the ratio of red to far-red light (R:FR) is reduced as a result of foliar shade.

Light and jasmonic acid coordinately regulate the phosphate responses under shade and phosphate starvation conditions in Arabidopsis

Plant Direct, 2023
In the natural ecosystem, plants usually grow at high vegetation density for yield maximization. The high‐density planting triggers a variety of strategies to avoid canopy shade and competes with their neighbors for light and nutrition, which are ...

Photoreceptor crosstalk in shade avoidance [PDF]

Current Opinion in Plant Biology, 2016
Plants integrate a variety of environmental signals to determine the threat of competitor shading and use this information to initiate escape responses, termed shade avoidance. Photoreceptor-mediated light signals are central to this process. Encroaching vegetation is sensed as a reduction in the ratio of red to far-red wavebands (R:FR) by phytochromes.

MYCs and PIFs Act Independently in Arabidopsis Growth Regulation

G3: Genes, Genomes, Genetics, 2020
Plants have a variety of strategies to avoid canopy shade and compete with their neighbors for light, collectively called the shade avoidance syndrome (SAS).

Blue light regulated shade avoidance [PDF]

Plant Signaling & Behavior, 2012
Most plants grow in dense vegetation with the risk of being out-competed by neighboring plants. These neighbors can be detected not only through the depletion in light quantity that they cause, but also through the change in light quality, which plants perceive using specific photoreceptors. Both the reduction of the red:far-red ratio and the depletion

Molecular control of crop shade avoidance [PDF]

Current Opinion in Plant Biology, 2016
The shade avoidance response (SAR) in crops can be detrimental to yield, as precious carbon resources are redirected to stem or petiole elongation at the expense of biomass production. While breeding efforts have inadvertently attenuated this response in staple crops through correlated selection for yield at high density, it has not been eliminated ...

Early developmental responses to seedling environment modulate later plasticity to light spectral quality. [PDF]

PLoS ONE, 2012
Correlations between developmentally plastic traits may constrain the joint evolution of traits. In plants, both seedling de-etiolation and shade avoidance elongation responses to crowding and foliage shade are mediated by partially overlapping ...
