| Abstract: | Different opinions about the origination of somaclonal variation, which is a very common phenomenon in plant tissue culture, exist, such as the activation of transposable elements and DNA methylation. A review about the progress achieved in this field since 1981 is presented in this paper. The genesis of somaclonal variation is discussed at both cytological level and molecular biological level. |
