Somatic embryogenesis has served as a model to understand the physiological and biochemical events that occur during plant developmental processes as well as a component to biotechnological advancement. [4] The first documentation of somatic embryogenesis was by Steward et al. in 1958 and Reinert in 1959 with carrot cell suspension cultures. [5 ...
Plant embryonic development, also plant embryogenesis, is a process that occurs after the fertilization of an ovule to produce a fully developed plant embryo. This is a pertinent stage in the plant life cycle that is followed by dormancy and germination . [ 1 ]
Organogenesis is the phase of embryonic development that starts at the end of gastrulation and continues until birth. During organogenesis, the three germ layers formed from gastrulation (the ectoderm, endoderm, and mesoderm) form the internal organs of the organism. [1] The endoderm of vertebrates produces tissue within the lungs, thyroid, and ...
The latter phase has been modelled using the ABC model, which describes the biological basis of the process from the perspective of molecular and developmental genetics.

The entire process of embryogenesis can be described with the aid of two maps: an embryo map, a temporal sequence of 3-dimensional images of the developing embryo, showing the location of cells of the many cell types present in the embryo at a given time, and an embryogenic tree, a diagram showing how the cell types are derived from each other ...
The callus growth and its organogenesis or embryogenesis can be referred into three different stages. Stage I: Rapid production of callus after placing the explants in culture medium Stage II: The callus is transferred to other medium containing growth regulators for the induction of adventitious organs.
An embryo is the initial stage of development for a multicellular organism.In organisms that reproduce sexually, embryonic development is the part of the life cycle that begins just after fertilization of the female egg cell by the male sperm cell.
Somatic embryogenesis is a method that has the potential to be several times higher in multiplication rates and is amenable to handling in liquid culture systems like bioreactors. Some explants, like the root tip , are hard to isolate and are contaminated with soil microflora that becomes problematic during the tissue culture process.
