Long noncoding RNA-mediated epigenetic regulation of auxin-related genes controls shade avoidance syndrome in Arabidopsis. [PDF]

EMBO J, 2023
The long noncoding RNA (lncRNA) AUXIN‐REGULATED PROMOTER LOOP (APOLO) recognizes a subset of target loci across the Arabidopsis thaliana genome by forming RNA–DNA hybrids (R‐loops) and modulating local three‐dimensional chromatin conformation.

ELONGATED HYPOCOTYL5 (HY5) and HY5 HOMOLOGUE (HYH) maintain shade avoidance suppression in UV-B. [PDF]

Plant J, 2023
SUMMARY Reductions in red to far‐red ratio (R:FR) provide plants with an unambiguous signal of vegetational shade and are monitored by phytochrome photoreceptors.

Making the most of canopy light: shade avoidance under a fluctuating spectrum and irradiance. [PDF]

J Exp Bot
In the field, plants face constantly changing light conditions caused by both atmospheric effects and neighbouring vegetation. This interplay creates a complex, fluctuating light environment within plant canopies.

The small-molecule pifithrin-α deactivates ETR1 to repress shade avoidance in <i>Arabidopsis</i>. [PDF]

Sci Adv
Shade avoidance syndrome (SAS) commonly occurs in plants sensing shading and the proximity of neighbors, leading to morphological and physiological changes that are detrimental to plant health and consequently crop yield.

Lights, location, action: shade avoidance signalling over spatial scales. [PDF]

J Exp Bot
Plants growing in dense vegetation need to flexibly position their photosynthetic organs to ensure optimal light capture in a competitive environment.

Functional Mapping of Genes Modulating Plant Shade Avoidance Using Leaf Traits. [PDF]

Plants (Basel), 2023
Shade avoidance syndrome (SAS) refers to a set of plant responses that increases light capture in dense stands. This process is crucial for plants in natural and agricultural environments as they compete for resources and avoid suboptimal conditions ...

Maize ZmWRKY28: a target to regulate shade avoidance response under high planting density. [PDF]

J Exp Bot, 2023
This article comments on: Zhang Z, Chen L, Yu J. 2023. Maize WRKY28 interacts with the DELLA protein D8 to affect skotomorphogenesis and participates in the regulation of shade avoidance and plant architecture. Journal of Experimental Botany74, 3122–3141.

Plant Morphology and a Phytochrome B Model Reveal That the Effects of Far-Red Light on Shade-Avoidance-Like Responses Persist Under High Light Intensity. [PDF]

Plant Cell Environ
Several studies have concluded that high photon flux density (PFD) attenuates the effects of the red (R; 600–699 nm) to far‐red (FR; 700–750 nm) light ratio on morphology.

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
