Phytochrome-interacting factors directly suppress MIR156 expression to enhance shade-avoidance syndrome in Arabidopsis. [PDF]
Nat Commun, 2017 Abstract Plants have evolved a repertoire of strategies collectively termed the shade-avoidance syndrome to avoid shade from canopy and compete for light with their neighbors. However, the signaling mechanism governing the adaptive changes of adult plant architecture to shade is not well understood.

Regulatory Components of Shade Avoidance Syndrome
Advances in Botanical Research, 2010 Competition for light has an important impact on plant development. Plants sense the presence of nearby competitor vegetation as a change in the light quality, i.e. a reduced red to far-red ratio. The responses to shade are generally referred to as the shade avoidance syndrome (SAS), and involve various developmental changes aimed to outgrow the ...

The molecular analysis of the shade avoidance syndrome in the grasses has begun [PDF]
Journal of Experimental Botany, 2007 The shade avoidance syndrome (SAS) is a morphological and physiological response initiated by a decrease in light quantity and a change in light quality. Recent work in Arabidopsis thaliana has begun to define the molecular components of the SAS in a model dicot species, but little is known of these networks in agronomically important grasses.

DRACULA2 is a dynamic nucleoporin with a role in regulating the shade avoidance syndrome in Arabidopsis. [PDF]
Development (Cambridge, England), 2016 When plants grow in close proximity basic resources such as light can become limiting. Under such conditions plants respond to anticipate and/or adapt to the light shortage, a process known as the shade avoidance syndrome (SAS). Following genetic screening using a shade-responsive luciferase reporter line (PHYB:LUC), we identified DRACULA2 (DRA2 ...

The shade avoidance syndrome: multiple responses mediated by multiple phytochromes [PDF]
Plant, Cell and Environment, 1997 ABSTRACTIn recent years, the concept of shade avoidance has provided a functional meaning to the role of the phytochrome photoreceptor family in mature plants in their natural environment, and the question of which of these phytochromes is responsible for shade avoidance reactions has inevitably been raised.

Shade Avoidance Syndrome: A Colour Ratio Regulated Growth
Asian Journal of Soil Science and Plant NutritionWhen plants are exposed to the shade of another plant, they exhibit a set of responses called shade avoidance syndrome (SAS). The most remarkable trait observed in plants subjected to low R:FR are an upward reorientation of leaves (leaf hyponasty) and a rapid elongation of leaves and stems.

Genotype by environment interactions for the shade avoidance syndrome in the plant Antirrhinum majus , the snapdragon [PDF]
, 2018 Abstract A classical example of phenotypic plasticity in plants is the set of trait changes in response to shade, i.e. the shade avoidance syndrome. There is widespread evidence that plants in low light conditions often avoid shade by growing taller or by increasing their ...

The shade avoidance syndrome in Arabidopsis: a fundamental role for atypical basic helix–loop–helix proteins as transcriptional cofactors [PDF]
Plant Journal, 2011 SummaryThe shade avoidance syndrome (SAS) refers to a set of plant responses aimed at anticipating eventual shading by potential competitors. The SAS is initiated after perception of nearby vegetation as a reduction in the red to far‐red ratio (R:FR) of the incoming light.

The Plant Journal, 2013 SummaryThe shade avoidance syndrome (SAS) refers to a set of plant responses initiated after perception by the phytochromes of light with a reduced red to far‐red ratio, indicative of vegetation proximity or shade. These responses, including elongation growth, anticipate eventual shading from potential competitor vegetation by overgrowing neighboring ...
