As a rule, excised root of most species produce only root tissues in culture. Several point mutations have been observed; the majority of analysed spontaneous genetic variants from somatic cultures appear to have resulted from induction of aneuploidy, loss of interchanges or intra-chromosomal segment duplication, deletions or structural arrangements.
While root regeneration is promoted by an auxin, such as NAA naphthalene acetic acid. Genetic transformation Genetic transformation is the most recent aspect of plant cell and tissue culture that provides the mean of transfer of genes with desirable trait into host plants and recovery of transgenic plants [ 63 ].
The young embryos develop into mature embryos either in the same medium or on another medium. This surge is due to its relative ease of use and understanding. Cryobionomics is a new approach to study genetic stability in the cryopreserved plant materials [ 46 ].
Such, cultures are known as meristem culture. The embryos of Cuscuta reflexa, a total stem parasite, were also cultured. Rinse with sterile distilled water, turn upside down on a clean counter or paper towels and allow to dry.
These cultures were shaken generally which freed all the cell clusters into the medium Some developed into rooting clumps When these were transferred to the tubes containing a semi-solid medium, they gave rise to whole plant that flowered and set seeds. Along with the totipotent potential of plant cell, the capacity of cells to alter their metabolism, growth and development is also equally important and crucial to regenerate the entire plant [ 1 ].
The embryonic tissues can be cryopreserved for future use or for germplasm conservation [ 47 ].
