apum24-2 and brx1-2 Mutants Have Similar Phenotypes.

(A) Photographs of shoots of 7-d-old seedlings (upper panel) and true leaves of 10-d-old seedlings (lower panel) of wild-type Arabidopsis, apum24-2, and the complemented line (Complemented), as well as the brx1-1 and brx1-2 mutants. Arrowheads indicate pointed leaves (upper panel) and serrated edge (lower panel). Bars = 1 mm.

(B) Time course of germination rates. The germination rates of 50 seeds were counted over time. Error bars indicate sd (n = 3).

(C) Photographs (upper panel) and quantification (lower panel) of primary root lengths of 7-d-old seedlings. Horizontal white lines were put on the tip of the primary roots. Error bars indicate sd (n = 7). Statistical significance was determined by ANOVA, followed by a Tukey-Kramer test. Means that are significantly different from each other (P < 0.05) are indicated by different letters. Bar = 1 cm.
