Abstract:
piggyBac-N1_BM is a relatively old family of nonautonomous piggyBac transposons, characterized by 15-bp TIRs (one mismatch) and TTAA target-site duplications. The consensus sequence was reconstructed based on multiple alignment of 25 copies that are ~93% identical to the consensus). The genome contains ~200 copies of piggyBac-N1_Bm that are ~90% identical to the consensus. The complete piggyBac-N1_BM DNA sequence is 88% identical to the planarian piggyBac-15_SM (Schmidtea mediterranea). piggyBac-N1_BM is a nonautonomous deletion derivate of piggyBac-15_SM (pos. 1-196, 2312-2356). The high nucleotide identity, including non-coding regions, between these transposons in two species diverged from their last common ancestor over 500 million years is a clear evidence of horizontal transfer of piggyBac transposons.
