What is Gametoclonal variation?

Gametoclonal variation has been defined as the variation among plants regenerated from gametic cells in culture (Evans et al., 1984; Morrison and Evans, 1987).

What is somaclonal variation in plant biotechnology?

Somaclonal variation is the variation seen in plants that have been produced by plant tissue culture. Chromosomal rearrangements are an important source of this variation. Somaclonal variation is not restricted to, but is particularly common in, plants regenerated from callus.

What is the meaning of somaclonal variation?

The term somaclonal variation is defined as genetic variation that is present in plants regenerated from tissue cultures, either uncovered or induced by a tissue culture process (Larkin and Scowcroft, 1981).

What are the causes of somaclonal variation?

Cause of Somaclonal Variation The somaclonal variation developed due to physiological activity such as plant hormone, plant growth regulators, and culture conditions of the media. This type of variation caused when the sample expose a longer time in a particular conditions.

Why micropropagation is called clonal propagation?

Multiplication of genetically identical copies of a cultivar by asexual reproduction is called clonal propagation and a plant population derived from a single individual by asexual reproduction constitutes a clone.

What is micropropagation in plant tissue culture?

Micropropagation or tissue culture is the practice of rapidly multiplying plant stock material to produce many progeny plants, using modern plant tissue culture methods.

What is somaclonal variation Byjus?

A. Somaclonal variation is the variation seen in animal that have been produced by animal tissue culture.

What are Soma clones?

Somaclones are the plants that are produced through tissue culture and are genetically identical to the parent plant from which they are produced and cultured.

What are the advantages of somaclonal variation?

Advantages. The major likely benefit of somaclonal variation is plant/crop improvement. Somaclonal variation leads to the creation of additional genetic variability.

Who discovered somaclonal variation?

The term somaclonal variation was first coined by Larkin and Scowcraft in 1981. According to Scowcraft genetic variation occurring in tissue culture regenerated plants through somatic tissues are commonly referred as somaclonal variation.

Who is the father of tissue culture?

Gottlieb Haberlandt is known as the father of plant tissue culture.
