The below mentioned article provides a study note on somatic embryogenesis. Somatic embryogenesis is the process in which a single cell or a small group of cells follow a developmental pathway that leads to reproducible regeneration of non-zygotic embryos which are capable of producing a complete plant. These non-zygotic embryos may originate directly from other organs or parthenogenetic embryos (without [...]
Let us make an in-depth study of the meaning, history, principles, protocols and importance of somatic embryogenesis. About Somatic Embryogenesis: What is Somatic Embryogenesis? In plant tissue culture, the developmental pathway of numerous well-organised, small embryoids resembling the zygotic embryos from the embryo genic potential somatic plant cell of the callus tissue or cells of suspension culture is known as [...]
The following points highlight the chemical and other factors affecting somatic embryogenesis. The chemical factors are: (a) Auxin (b) Cytokinin (c) Gibberellin and (d) Reduced Nitrogen. (1) Chemical Factors: a. Auxin: Somatic embryogenesis in carrot is a classic example. It is a two-step process. The carrot cells first develop into a callus tissue in the medium containing the auxin, namely [...]
