Red light regulation of APY levels during de-etiolation across seedling organs. APY mRNAs and APY proteins accumulate in fast growing tissues, such as the hypocotyl of etiolated seedlings (Wu et al., 2007). After short times of red light (R) irradiation, hypocotyl growth is arrested, which coincides with the suppression of APY levels in this organ (Wu et al., 2007). R treatment promotes a gradual increase in APY proteins in the apical hook and cotyledons, which matches the dynamics of hook opening and cotyledon expansion. Root growth is initially attenuated by R (Correll and Kiss, 2005) but then enhanced at later points (Kircher and Schopfer, 2012). Coincidentally, R lowers APY proteins levels after 6–12 h of treatment, but both gene expression and protein accumulation are upregulated after 24 h. Tissues where APY transcripts and proteins were measured are enclosed with dotted lines. Created with BioRender.com.
