Functional analysis of PHYB polymorphisms in Arabidopsis thaliana collected in Patagonia
Frontiers in Plant Science, 2022 Arabidopsis thaliana shows a wide range of natural genetic variation in light responses. Shade avoidance syndrome is a strategy of major adaptive significance that includes seed germination, elongation of vegetative structures, leaf hyponasty, and ...

Temperature-dependent shade avoidance involves the receptor-like kinase ERECTA [PDF]
, 2012 Plants detect the presence of neighbouring vegetation by monitoring changes in the ratio of red (R) to farred (FR) wavelengths (R:FR) in ambient light.

The Arabidopsis Book, 2012 The presence of neighboring vegetation modifies the light environment experienced by plants, generating signals that are perceived by phytochromes and cryptochromes. These signals cause large changes in plant body form and function, including enhanced growth of the hypocotyl and petioles, a more erect position of the leaves and early flowering in ...

Phytochrome interacting factors 4 and 5 control seedling growth in changing light conditions by directly controlling auxin signaling. [PDF]
, 2012 Plant growth is strongly influenced by the presence of neighbors that compete for light resources. In response to vegetational shading shade-intolerant plants such as Arabidopsis display a suite of developmental responses known as the shade-avoidance ...

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 ...

Green Light Induces Shade Avoidance Symptoms [PDF]
Plant Physiology, 2011 Abstract Light quality and quantity affect plant adaptation to changing light conditions. Certain wavelengths in the visible and near-visible spectrum are known to have discrete effects on plant growth and development, and the effects of red, far-red, blue, and ultraviolet light have been well described.

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.

Shade delays flowering in Medicago sativa [PDF]
, 2019 Shade intolerant plants respond to the decrease in the red (R) to far-red light (FR) ratio (R:FR) occurring under shade by elongating stems and petioles and re-positioning leaves, in a race to out-compete neighbors for the sunlight resource.

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 ...

Palisade cell shape affects the light-induced chloroplast movements and leaf photosynthesis [PDF]
, 2018 Leaf photosynthesis is regulated by multiple factors that help the plant to adapt to fluctuating light conditions. Leaves of sun-light-grown plants are thicker and contain more columnar palisade cells than those of shade-grown plants.
