What is the Difference Between Organogenesis and Somatic Embryogenesis

The major difference between organogenesis and somatic embryogenesis is that organogenesis is the process which generates plant organs including shoot and root from vegetative tissue while somatic embryogenesis is the process which generates embryonic callus from vegetative tissue.

What is somatic embryogenesis and organogenesis?

Organogenesis involves inducing the vegetative tissue to form organs (shoot or root) which eventually develop into a complete plantlet (small but whole plant), while, somatic embryogenesis is to induce a piece of somatic (vegetative) tissue to develop an embryogenic callus, leading to the formation of a somatic embryo ...

What is the meaning of somatic embryogenesis?

Somatic embryogenesis is defined as the propagation of the embryo or plant from single or a group of vegetative cells. In plants there are two types of cells, vegetative, and germ cells. Somatic embryos are formed from vegetative cells that are not involved in the development of embryos.

What is organogenesis in plants?

Several tissues are organized together to form an organ, such as leaves, roots, flowers and the vascular system. The process of initiation and development of an organ is called organogenesis. In plant tissue culture, inducing organogenesis is an important way to regenerate plants from the culture.

What are the types of organogenesis?

There are three ways of organogenesis (by which adventitious organs form): (1) from the callus culture, (2) from an explant, and (3) from the axillary bud. The organogenesis by axillary bud development can be used to regenerate the whole plant from some types of tissue culture.

What is somatic embryogenesis and its importance?

Somatic embryogenesis is an artificial process in which a plant or embryo is derived from a single somatic cell. ... 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.

Why is somatic embryogenesis important?

In woody plants, somatic embryogenesis plays a critical role in clonal propagation and is a powerful tool for synthetic seed production, germplasm conservation, and cryopreservation. A key step in somatic embryogenesis is the transition of cell fate from a somatic cell to embryo cell.

What does somatic mean?

1 : of, relating to, or affecting the body especially as distinguished from the germplasm. 2 : of or relating to the wall of the body : parietal.

What are the factors affecting somatic embryogenesis?

Factors Affecting Somatic Embryogenesis

• Explant. The choice of explant depends on the species of plant to be induced for embryogenesis. ...
• Genotype. The genotypic variation between the plants also affects the process of embryogenesis. ...
• Growth Regulators. ...
• Nitrogen Source. ...
• Polyamines.

What is the meaning of somatic cell?

A somatic cell is any cell of the body except sperm and egg cells. Somatic cells are diploid, meaning that they contain two sets of chromosomes, one inherited from each parent. Mutations in somatic cells can affect the individual, but they are not passed on to offspring.

How does organogenesis occur?

Organogenesis is the process by which the three germ tissue layers of the embryo, which are the ectoderm, endoderm, and mesoderm, develop into the internal organs of the organism. For example, some cells in the ectoderm will express the genes specific to skin cells. ...

Where does organogenesis occur?

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.

What are germinal layers?

Germ layer, any of three primary cell layers, formed in the earliest stages of embryonic development, consisting of the endoderm (inner layer), the ectoderm (outer layer), and the mesoderm (middle layer). ...
