| evidence for interspecific transfer of the transposable element mariner between drosophila and zaprionus. | the transposable element mariner occurs widely in the melanogaster species group of drosophila. however, in drosophilids outside of the melanogaster species group, sequences showing strong dna hybridization with mariner are found only in the genus zaprionus. the mariner sequence obtained from zaprionus tuberculatus is 97% identical with that from drosophila mauritiana, a member of the melanogaster species subgroup, whereas a mariner sequence isolated from drosophila tsacasi is only 92% identical ... | 1991 | 1664000 |
