Currently, the
term somaclonal variation is generally used to describe all
the variations from tissue culture. However, other
alternative terms such as 'protoclonal' or 'gametoclonal',
describing variation from protoplast and anther culture,
respectively, are also used (Karp, 1994). Somaclonal
variation is an important phenomenon that can be observed
at varying levels in plant tissue culture in both dicot (Brar &
Jain, 1998) and monocot families (Cheng et al., 1992;
Chang et al., 2003).
