Shade Avoidance Components and Pathways in Adult Plants Revealed by Phenotypic Profiling

Abstract: 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 syndrome (SAS). The SAS includes elongation of a variety of organs, acceleration of flowering time, and additional physiological responses, which are seen throughout the plant life cycle. However, current mechanistic knowledge is mainly limited to shade-induce… Show more

“…The importance of multiple hormones in shade-regulated morphogenesis prompted us to focus on GO terms associated with hormone responses (Tao et al, 2008;Hornitschek et al, 2012;Li et al, 2012;Bou-Torrent et al, 2014;Procko et al, 2014;Nozue et al, 2015). Consistent with the early role of auxin in this process, the term response to auxin was significantly overrepresented among genes upregulated by shade both in hypocotyls and cotyledons at all time points of our analysis ( Figure 2C).…”

“…In the sun (high R/FR ratio), active phyB inhibits several elongation-promoting bHLH factors from the Phytochrome Interaction Family (PIF; de Leivar and Monte, 2014). Low R/FR releases phyB-mediated inhibition of several PIFs, leading to shade-induced elongation of hypocotyls and petioles (Lorrain et al, 2008;Keller et al, 2011;Leivar et al, 2012;Li et al, 2012;de Wit et al, 2015;Mizuno et al, 2015;Nozue et al, 2015). Shade-induced auxin biosynthesis in the cotyledons and young leaves followed by transport of the phytohormone into the hypocotyl is considered essential to trigger hypocotyl elongation (Steindler et al, 1999;Tao et al, 2008;Keuskamp et al, 2010;de Wit et al, 2014;Procko et al, 2014Procko et al, , 2016.…”
