Araucaria angustifolia tissues/organs used in this study.
Globular zygotic embryos (left, scale bar = 1 mm, and the megagametophyte (right, scale bar = 10 mm) (A); late cotyledonal zygotic embryo (B) and the corresponding megagametophyte (C); aciculas (D); abscisic acid (ABA)-responsive (E), ABA non-responsive (F) and mature ABA-responsive (G) embryogenic cell lines. Arrows indicate globular somatic embryos. Scale bars for panels b-g = 10 mm, 10 mm, 100 mm, 10 mm, 10 mm and 10 mm, respectively.
