UGT76F1 affects BR-mediated hypocotyl elongation.

(a and c) The UGT76F1 overexpression lines reduced the sensitivity to BL. Seedlings were grown on media containing various concentrations of BL at 28°C for 4 d. Representative seedlings grown on either mock (0 nM BL) or BL (1–100 nM BL) media are shown in (a). (b and d) The ugt76f1 mutant lines reduced the sensitivity to PPZ. Seedlings were grown either on mock (0 nM PPZ) or PPZ (20–100 nM PPZ) at 28°C for 4 d. Data are means ± SD, n = 30. Significant difference was compared to respective WT. Student’s t-test was performed (**P < 0.01).
