YABBY and the kan1 kan2 kan4 Cotyledon and Hypocotyl Outgrowths.

(A) and (B) In kan1 kan2 kan4 fil yab3 yab5 (k124fily35) (B), outgrowths (arrows) forming on the hypocotyl are similar in shape to kan1 kan2 kan4 (k124) (A) outgrowths (arrows) but do not reach the full length of the kan1 kan2 kan4 outgrowths. Three narrow cotyledons (cot) develop in kan1 kan2 kan4 fil yab3 yab5 plants (B). The cotyledons lack the outgrowths (asterisks) observed on the abaxial side of kan1 kan2 kan4 cotyledons (A).

(C) to (G) mRNA expression pattern of FIL in kan1 kan2 kan4 embryos. At the early (D) and late (E) heart stages, FIL expression in kan1 kan2 kan4 is similar to that in the wild type (C) and confined to the abaxial side of developing cotyledons. During the torpedo stage, FIL expression is seen throughout hypocotyl outgrowth primordia (arrow) (G) and on the abaxial side of the cotyledons, as in the wild type (F).
