<i>brm</i> mutants show GA-related phenotypic traits and increased sensitivity to paclobutrazol.

<p>(A), Comparison of <i>brm-1</i> and <i>ga1-3</i> mutants grown on ½ MS medium for 18 days under long-day conditions. (B), Germination of the <i>brm-1</i> mutant is abolished in the presence of 10 µM PAC and rescued upon addition of exogenous gibberellin. The progeny of <i>brm-1/BRM</i> plants were analyzed 14 days after sowing. (C), Phenotype of <i>brm-1</i> plants grown for 25 days on 10 µM PAC after incubation of seeds with exogenous GA. (D), Germination assay of wild type, <i>brm-3</i> and <i>3xdella</i> (<i>rga/rgl1/rgl2</i>) lines. Seed coat rupture after 14 days was scored as germination. (E), Root elongation assay of wild type and <i>brm-3</i> plants grown for 12 days on PAC-containing medium. Bars in A, C and E = 5 mm.
