Fig. 1. A comparison of wild-type and bodenlos or monopteros seedlings and embryos. (A) Wild-type embryo. (B) Phenotype of a bodenlos (bdl) embryo. (Note that the phenotype of monopteros [mp] is identical to that of bodenlos [bdl].) Both bdl and mp mutants show a defect in the division plane of the hypophyseal cell (red arrows), and have defects in root formation, although both proteins accumulate in the cells above the hypophyseal cell (green outline in A). Scale bar: 25 µm. Fig. 1 courtesy of D. Weijers (Wageningen University, Wageningen, The Netherlands).
