| Abstract: | Intertribal somatic hybridization between wild type Brassica juncea (L.) Czern. & Coss. and transgenic A. thaliana L. has been carried out. Genome of A. thaliana plants contained heterologous transposable element Spm/dSpm, reporter GUS gene, selective genes for kanamycin- (npt II) and phosphinothricin (bar) resistance. Hybrid nature of obtained plants was confirmed with their morphology, GUS hystochemical assay, PCR-RFLP, RAPD and isozyme analyses. It was determined that heterologous transposable element Spm/dSpm is able to function in hybrid plants. There was no complete elimination of A. thaliana genetic material in the hybrids and the transgenes were stably maintained. |
