HY5-dependent induction of ABCI20 and ABCI21 upon light exposure.
(a) Promoters of ABCI19, ABCI20 and ABCI21 contain HY5-responsive elements (ACGT containing elements and/or G-box).
(b) Relative transcript levels (mean values ± SD) of ABCI19, ABCI20 and ABCI21 in hy5–1 and the wild type (Ler) under various light/dark conditions. Gene expression levels were measured by qRT-PCR and normalized by the β–Tubulin 8 expression level. Asterisks indicate significant differences between Ler and hy5–1 (p < 0.05, Student’s t test), and hashtags indicate significant differences between light-exposed samples and dark control (p < 0.05, Student’s t test; N=2, n=3).
