Abstract
Plasmid-based transposition assays were performed in develo** embryos of the Australian sheep blowfly Lucilia cuprina and the Queensland fruit fly Bactrocera tryoni, using the mariner transposable element from Drosophila mauritiana. Transposition products were recovered that were identical in structure to those recovered from D. melanogaster. Only sequences delimited by the mariner terminal repeats were transposed and all insertions occurred at TA residues, and duplicated these. These are the hallmarks of mariner transpositions observed in the chromosomes of D. melanogaster and D. mauritiana, indicating that the plasmid-based assays are accurate indicators of mariner transposition activity. The recovery of precise transposition products from L. cuprina and B. tryoni demonstrates that mariner should be capable of producing germline transformants in these species. The results obtained from these assays suggests that they will be extremely useful in determining if mariner can transpose in other non-drosophilid insects and for investigating factors that might affect mariner transposition frequency.
