Expert Answer
Somatic cell hybridisation involves the fusion of somatic or body cells from two different varieties of a species or even from two different species.
Process of Somatic Cell Hybridisation
- Cell walls of somatic cells are removed by the use of certain chemical and enzymes to form protoplasts.
- The protoplasts are then fused either by chemicals or by a very brief high-voltage electric current to form a fused nucleus called heterokaryon.
- The protoplasts are then cultured and treated chemically to regenerate cell walls.
- They begin to divide and produce plantlets.
- Examples of plants propagated through somatic cell hybridisation: Potato, tomato, wheat, rye.
