UVR8 variants show defective transcriptional regulation of <i>RUP1</i> and <i>RUP2</i> by photomorphogenic UV-B.

<p>(A–B) qRT-PCR analysis of <i>RUP1</i> (A) and <i>RUP2</i> (B) in 4-day-old seedlings grown under −UV-B and +UV-B. Data are shown as mean ± SD; n = 3. (C–D) qRT-PCR analysis of <i>RUP1</i> (C) and <i>RUP2</i> (D) in 4-day-old seedlings transferred from −UV-B to +UV-B and harvested at indicated time points. Data are shown as mean ± SD; n = 3.
