Comparison of the roles of auxin and cytokinin during RAM specification in zygotic and somatic embryos. The cells with green color represent established RAM niche in zygotic embryogenesis (ZE) and somatic embryogenesis (SE) respectively. The dashed lines stand for proposed molecular link but need to be further corroborated. S, Suspensor; LSC, Lens-Shaped Cell; BC, Basal Cell lineage; RSC, root stem cells of SE.
