Your question: Who first developed interspecific somatic hybrid?

It is a type of genetic modification in plants by which two distinct species of plants are fused together to form a new hybrid plant with the characteristics of both. It may be intraspecific, interspecific, intrageneric, and intergeneric. Somatic hybridization was first introduced by Carlson et al. in Nicotiana glauca.

What are interspecific somatic hybrids?

Abstract. Somatic hybrid plants between a dihaploid potato, BF15, and one of its wild tuber-bearing relatives, Solanum berthaultii, were produced after protoplast electrofusion with the objective of transferring insect resistance, which is associated with the presence of glandular hairs, into potato lines.

When was somatic hybridization invented?

This paper charts the origins of somatic hybridization and its rise and fall as a plant breeding technique. During the 1960s and 1970s, the creation of somatic hybrids through cell fusion promised a new era of crop improve- ment.

Who discovered protoplast fusion?

In 1974, Kao and Michayluk from Canada discovered another fusion inducing chemical polyethylene glycol (PEG) which is the most effective agent discovered so far. Many fusion experiments are performed by a polyethylene glycol. PEG induces protoplast aggregation and subsequent fusion.

How somatic hybrids are produced?

Somatic hybrids are formed by the fusion of nuclei and cytoplasm of two species. After the production of first somatic hybrids involving Nicotiana glauca and N. langsdorfi, various intraspecific, interspecific, and intergeneric somatic hybrids have been generated.

What are somatic hybrids give an example?

The plants produced from tissue culture are genetically identical to the original plant from which they are grown, so they are called somaclones. Example- Banana. Fusion of two somatic cells of different varieties is called somatic hybrids. Example- Pomato (Tomato hybrid + Potato hybrid)

Is potato a somatic hybrid?

Somatic hybridization has been used in potato to overcome the sexual barriers between the cultivated (Solanum tuberosum L.) and wild species.

What is called somatic hybridization?

Somatic hybridization is the technique that allows manipulation of the cellular genome by a process called protoplast fusion. It is a type of genetic modification in plants by which two distinct species of plants are fused together to form a new hybrid plant with the characteristics of both.

Is Pomato a somatic hybrid?

Pomato is the Potato and Tomato hybrid. … Pomato can be formed by somatic hybridization. The mechanism by which two separate species of plant protoplasts fuse together to form hybrids is known as somatic hybridization. Pomato is an example of allopolyploid.

What do mean by protoplast fusion?

Definition English: Somatic fusion, also called protoplast fusion, is a type of genetic modification in plants by which two distinct species of plants are fused together to form a new hybrid plant with the characteristics of both, a somatic hybrid.
