title: Highly similar piggyBac transposase-like sequences from various Bactrocera (Diptera, Tephritidae) species.
abstract: The piggyBac transposable element is currently the vector of choice for transgenesis, enhancer trapping, gene discovery and gene function determination in both insects and mammals. However, the recent discovery of sequences with similarity to piggyBac in a wide diversity of organisms suggests that piggyBac may be horizontally transferred to distantly related species. This has raised concern on the wide-range application of piggyBac-based transformation vectors and their stability. In this paper, the presence of sequences homologous to the piggyBac transposase was investigated in 17 species belonging to six genera within the Tephritidae family, including many pest species for which transformation has already been achieved. piggyBac-like sequences, with a high degree of similarity to the original Trichoplusia ni transposase sequence were identified only in six species of the Bactrocera genus.
