Abstract:
piggyBac-1_BM is a very young family of piggyBac transposons, characterized by 15-bp TIRs (one mismatch) and TTAA target-site duplications. The consensus sequence was reconstructed based on multiple alignment of 7 copies that are ~99.9% identical to the consensus). The transposase is probably incomplete due to deletion of its short N-terminus. Surprisingly, the complete piggyBac-1_BM DNA sequence is 88% identical to the planarian piggyBac-8_SM (Schmidtea mediterranea). The high nucleotide identity, including non-coding regions, between these transposons in two species diverged from their last common ancestor over 500 million years ago, is a first clear evidence of horizontal transfer of piggyBac transposons.
