Abstract:
piggyBac-15_SM is a family of piggyBac transposons, characterized by 14-bp TIRs (2 mismatches) and TTAA target-site duplications. The consensus sequence was reconstructed based on multiple alignment of 10 copies, which are ~97% identical to the consensus sequence. The silkworm genome contains >100 copies of the 242-bp nonautonomous piggyBac-N1_BM transposons, which is a deletion derivate of piggyBac-15_SM. These transposons are 93% identical to each other. Given that planarians and insects have split from their last common ancestor more than 500 million years ago, evolution of these two families of piggyBac included horizontal transfer.
