| Abstract: | Plasmid DNA clones containing repetitive DNA sequences were isolated from Hyoscyamus muticus and Nicotiana tabacum. Non cross-hybridizing probes from each species were used in a simple hybridization test with DNA isolated from presumptive somatic hybrids. This allowed unequivocal identification of DNA from both species in the hybrids. |
