somaclonal variation

The major likely benefit of somaclonal variation in plant is improvement.

Different steps can be used to reduce somaclonal variation.

Somaclonal variation leads to the creation of additional genetic variability.

There are both benefits and disadvantages to somaclonal variation.

These are also used in somaclonal variation.

Somaclonal variation is the variation seen in plants that have been produced by plant tissue culture.

Other techniques by which humans modify food organisms include selective breeding and somaclonal variation.

In the case of plant tissue cells somaclonal variation may arise over long periods in culture.

He was co-contributor to the discovery that somaclonal variation occurs in plants and can be used for plant improvement.

It was developed through a process known as somaclonal variation, which entails growing plant shoots from cells in petri dishes.

Somaclonal variation is not restricted to, but is particularly common in, plants regenerated from callus.

The phenomenon of high variability in individuals from plant cell cultures or adventitious shoots has been named somaclonal variation.

Another way of reducing somaclonal variation is to avoid 2,4-D in the culture medium, as this hormone is known to introduce variation.

The recipe is used to promote somaclonal variation, the method of growing plants from a speck of tissue in a Petri dish.

The first is somaclonal variation, a characteristic recognised in cloned species which exhibit variation in genetic structure.

On the other hand, somaclonal variation provides a new range of material by expanding the gene pool of a particular species, with which plant breeders can experiment.

In the mid 1980s, DNAP attempted to use somaclonal variation with corn to produce buttery-tasting popcorn without the need to add butter.

Methods have also been developed for the control of contaminating microbes, early detection and elimination of somaclonal variation, reduction of labor and fixed costs in production etc.

It is well known that increasing numbers of subculture increases the likelihood of somaclonal variation, so the number of subcultures in micropropagation protocols should be kept to a minimum.

For example, Kunakh and Savchenko (1988) have reported somaclonal variation in two related stocks of maize, of which one displayed a greater variety of morphological features and adaptability.

Classical plant breeders also generate genetic diversity within a species by exploiting a process called somaclonal variation, which occurs in plants produced from tissue culture, particularly plants derived from callus.

Similarly, Larkin et al.(1988) have reported somaclonal variation in cultivars of wheat which produced a range of traits in mature individuals, including variation in resistance to the herbicide glyphosate.

Known as somaclonal variation, the method consists of removing tissue from a high-quality tomato, placing it in a petri dish filled with nutrients, and allowing the cells to reproduce and form new shoots.

A serious disadvantage of somaclonal variation occurs in operations which require clonal uniformity, as in the horticulture and forestry industries where tissue culture is employed for rapid propagation of elite genotypes.

The first method involving the meristems and induction of multiple shoots is the preferred method for the micropropagation industry since the risks of somaclonal variation (genetic variation induced in tissue culture) are minimal when compared to the other two methods.
