Figure 2.

The Embryo Phenotype of kan1 kan2 kan4.

(A) and (B) Wild-type (A) and kan1 kan2 kan4 (k124) (B) early heart stage embryos. Periclinal cell divisions are already visible in the kan1 kan2 kan4 subepidermal layer (arrows).

(C) and (D) Cotyledons are at a more obtuse angle and the region that will give rise to the SAM is broader in kan1 kan2 kan4 embryos (D) than in wild-type embryos (C). Arrows in (D) indicate abnormal periclinal cell divisions that will give rise to the cotyledon and hypocotyl outgrowths.

(E) and (F) Torpedo stage kan1 kan2 kan4 embryo (F) with cotyledon (cot) and hypocotyl (hyp) outgrowths (arrows), which are lacking in the wild-type torpedo stage embryo (E).
