BBX7 and BBX8 redundantly act downstream of HY5 to positively regulate plant freezing tolerance. A–C, Freezing phenotypes (A), survival rates (B), and ion leakage (C) of Col-0, the bbx7 bbx8 double mutant, and bbx7 bbx8 BBX7#1, bbx7 bbx8 BBX8#1 complementation lines. D–F, Freezing phenotypes (D), survival rates (E), and ion leakage (F) of Col-0, BBX7-Myc and BBX8-Myc overexpression lines. G–I, Freezing phenotypes (G), survival rates (H), and ion leakage (I) of Col-0, hy5-215, hy5-215 BBX7-Myc, and hy5-215 BBX8-Myc transgenic lines. In (B, C, E, F, H, and I), data are means of three independent experiments ± sem (n = 30). Asterisks indicate significant differences compared with Col-0 under the same treatment (*P < 0.05, **P < 0.01, Student’s t test).
