Constitutive expression of APY2 promotes light-induced changes in SAUR50 and SAUR17 gene expression in the hook-cotyledon tissue of 4-day-old, etiolated seedlings. Relative expression levels of SAUR50 and SAUR17 (A) WT Ws in dark versus after 3 h of white light. B, WT Ws in dark versus APY2 OE in dark. The data represent average of 4–10 technical replicates of RNA extracted from tissue pooled from five independently grown plates of seedlings. * Denotes significantly different expression from the WT Ws expression level calibrator (P < 0.05, Student’s t test, error bars are se).
