    Abstract

    © Springer Science+Business Media, LLC, part of Springer Nature 2019. Plants detect neighboring vegetation as potential competitors for resources. Vegetation proximity is perceived by changes in the red (R) to far-red (FR) ratio (R:FR) through the phytochrome photoreceptors. To face this challenge, many plants have evolved the strategy to avoid shade, displaying a series of responses known as the shade avoidance syndrome (SAS). The SAS responses have been mostly studied at the seedling stage, and cover hypocotyl elongation as well as cotyledon and primary leaf expansion. In adult stages, SAS responses include an increase in petiole elongation and a decrease in leaf expansion, and an increase in plant height. Thus, the analysis of these responses provides a valuable and simple way to study how vegetation proximity affects plant development in both seedlings and adult plants. Here we describe a simple protocol to simulate shade in the laboratory and to evaluate these responses. Overall, our protocol can be easily used to expand the set of SAS responses of plants at different stages of development.
