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.

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-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.

Effect of Temperature Variation and Blue and Red LEDs on the Elongation of Arugula and Mustard Microgreens

Horticulturae, 2023
Recent studies using LED lighting at low to modest intensity have indicated that compared with red light, blue light can promote plant elongation in many crops as a shade avoidance response despite varying sensitivity with light environments, plant ...

High planting density induces the expression of GA3-oxidase in leaves and GA mediated stem elongation in bioenergy sorghum

Scientific Reports, 2021
The stems of bioenergy sorghum hybrids at harvest are > 4 m long, contain > 40 internodes and account for ~ 80% of harvested biomass. In this study, bioenergy sorghum hybrids were grown at four planting densities (~ 20,000 to 132,000 plants/ha) under ...

Variation in plastic responses to light results from selection in different competitive environments-A game theoretical approach using virtual plants.

PLoS Computational Biology, 2019
Phenotypic plasticity is a vital strategy for plants to deal with changing conditions by inducing phenotypes favourable in different environments. Understanding how natural selection acts on variation in phenotypic plasticity in plants is therefore a ...

Identification of GA20ox2 as a target of ATHB2 and TCP13 during shade response

Frontiers in Plant Science, 2023
The shade avoidance syndrome (SAS) is a collective adaptive response of plants under shade highlighted by characteristic phenotypes such as hypocotyl elongation, which is largely mediated by concerted actions of auxin and GA.

Arabidopsis DNA topoisomerase I alpha is required for adaptive response to light and flower development

Biology Open, 2017
DNA topoisomerase I alpha (TOP1α) plays a specific role in Arabidopsis thaliana development and is required for stem cell regulation in shoot and floral meristems.

Functional Characterization of the Maize Phytochrome-Interacting Factors PIF4 and PIF5

Frontiers in Plant Science, 2018
Phytochrome-interacting factors (PIFs) play important roles in photomorphogenesis, the shade avoidance response, and other aspects of plant growth and development.
