Fig. 1

a The morphology of 1-week-old, 2-week-old, 3-week-old, and 4-week-old wild-type and p35S:AHL15 seedlings and plants grown in long day conditions (16 h photoperiod). b Two-week-old p35S:AHL15 Arabidopsis seedling with somatic embryos on the cotyledons (arrowheads). c, d Scanning electron micrographs showing torpedo stage somatic embryos on p35S:AHL15 cotyledons (c) or the secondary somatic embryos formed on a p35S:AHL15 primary somatic embryo (d). e The morphology of a 3-week-old AHL15 overexpression-induced embryonic mass following secondary SE. f The morphology of a 2-month-old embryonic mass formed from a p35S:AHL15 seedling. Size bars indicate 0.5 cm (a) and 1 mm (b–f). a–f Similar results were obtained from four independent experiments.
