TcBBM overexpression in cacao leads to spontaneous direct somatic embryogenesis. A. 35S::TcBBM cacao embryo over-expressing TcBBM going through the process of spontaneous direct somatic embryogenesis. B. Further development of same E12-Ω-CaMV-35S::TcBBM cacao embryo (14 days after image on A). C. E12-Ω-CaMV-35S::TcBBM explant after 14 days of being subjected to hormone induced somatic embryogenesis. D. SCA6 wild-type cacao embryo showing normal cotyledon development and no spontaneous embryo regeneration. Image scale bars = 1 mm.
