Study Notes
Somatic Embryogenesis
- Somatic embryos are formed from somatic cells, which are non-reproductive cells that make up the majority of an organism's cells.
Role of Plant Growth Regulators
- Plant growth regulators (PGRs) play a crucial role in somatic embryogenesis as they stimulate the formation of somatic embryos by regulating cellular differentiation and growth.
Laboratory Production
- Somatic embryos are mainly produced in laboratory cultures, such as tissue culture or cell suspension cultures, for research and application purposes.
Significance of First Documentation
- The first documentation of somatic embryogenesis by Steward et al. and Reinert (1950s-1960s) was significant because it demonstrated the potential for plant cells to differentiate into embryos, challenging the traditional view that only fertilized eggs could give rise to embryos.
Definition of Somatic Embryogenesis
- Somatic embryogenesis is the process by which somatic cells develop into embryos, mimicking the process of zygotic embryogenesis, but without the fertilization of an egg cell.

Description
Test your knowledge about the artificial process of somatic embryogenesis, where plant embryos are derived from single somatic cells. Learn about the formation of somatic embryos from ordinary plant tissue and the manipulation of plant growth regulators in tissue culture medium.
