Hypocotyl Response to GR24^4DO, GR24^ent-5DS, or GR24^4DO Plus GR24^ent-5DS.

(A) Seedlings of Col-0 (wild type), smax1, smxl2, smax1 smxl2, and smxl6,7,8 triple mutant were grown on 0.5× MS media containing 100 nM of each compound for 4 d under continuous red light at 21°C. Values are means ± sd. Different letters indicate significant difference at P < 0.05 (n = 20 different plants, two-way ANOVA multiple comparison, Tukey test, three independent experiments; Supplemental Data Set).

(B) Seedlings of Col-0 (wild type), 35S:SMXL2D-GFP/Col-0, and 35S:SMXL6D-GFP/Col-0 were grown on 0.5× MS media containing 100 nM of each compound for 4 d under continuous red light at 21°C. Values are means ± sd. Different letters indicate significant difference at P < 0.05 (n = 15 different plants, two-way ANOVA multiple comparison, Tukey test, three independent experiments; Supplemental Data Set).

(C) Seedlings of 35S:SMXL2-GFP/Col-0, 35S:SMXL2-GFP/d14-1, and 35S:SMXL2-GFP/kai2-2 were grown on 0.5× MS media containing 100 nM of each compound for 4 d under continuous red light at 21°C. Values are means ± sd. Different letters indicate significant difference at P < 0.05 (n = 15 different plants, two-way ANOVA multiple comparison, Tukey test, three independent experiments; Supplemental Data Set).
