[Creation and analysis of Brassica napus + Arabidopsis thaliana somatic hybrids possessing maize Spm/dSpm heterologous transposable system].

Functionally asymmetric somatic hybrids possessing heterologous transposable element Spm/dSpm were obtained following intertribal somatic hybridization between Brassica napus and transgenic Arabidopsis thaliana. Mobile genetic elements actively transposed in the hybrid genomes. Complete elimination of A. thaliana genome was not observed.
