Somaclonal variation ppt sites

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. Chromosomal rearrangements are an important source of this variation. Genetic variations in plants that have been produced by plant tissue culture and can be detected as genetic or phenotypic traits. Basic Features of Somaclonal Variations Variations for Karyotype, isozyme characteristics and morphology in somaclones may also observed. Feb 13,  · Sources of variations detected in plant tissue culture. Tissue culture is an efficient method of clonal propagation; however, the resulting regenerants often has a number of somaclonal variations (Larkin and Scowcroft ).These somaclonal variations are mainly caused by newly generated mutations arising from tissue culture process (Sato et al. b).Cited by:

Advantages Somaclonal variations are stable and occur at high frequencies. Somaclonal variations may show novel mutations. Can be performed in all types of cells, ie; vegetatively or sexually or asexually propagated plants. Somaclonal variations may reduce two years the time required for the release of new variety compared to mutation breeding. 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. The term somaclonal variation is a phenomenon of broad taxonomic occurrence, reported for species of different ploidy levels, and for outcrossing and inbreeding, vegetatively and seed propagated, and cultivated and non-cultivated plants. - Somaclonal variation It is the genetic modification occurring both in the PPT Presentation Summary: Somaclonal variation It is the genetic modification occurring both in the cell and in the tissue due to the use of in vitro technique PLANT BREEDING METHOD. 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. Chromosomal rearrangements are an important source of this variation. ADVERTISEMENTS: In this article, we will discuss about the possible mechanisms causing somaclonal variations. What is Somaclonal Variation? Plants derived from tissue culture has been variously referred to as somaclones or calliclones or protoclones and the variations displayed by such plants are simply called ‘somaclonal varia­tion’.somaclonal variations by Aisha Ashraf Department of botany, University of punjab Lahore, Pakistan- authorSTREAM Presentation. pigeonpea. The extent 01 Somaclonal variation as seen from tho following standard the intergenic spacer of rRNA genes located at the sites of nucleolar organizer regions (Nor loci). Accepted as poster presentation at Congress. Section 1 Concept and selection of plant somatic clone variation. Somaclonal variation can pose a serious problem in any .. This implies that variation may be generated from different locations of the genome. Genetic variations in plants thathave been produced by plant tissueculture and can be detected asgenetic or phenotypic traits.
