Two piggyBac-like elements (PLEs) were identified in the cotton bollworm, Helicoverpa armigera, and were designated as HaPLE1 and HaPLE2. HaPLE1 is flanked by 16 bp inverted terminal repeats (ITRs) and the duplicated TTAA tetranucleotide, and contains an open reading frame (ORF) of 1794 bp with the presumed DDD domain, indicating that this element may be an(More)
PiggyBac-like elements (PLE) are widespread in variety of organisms, however, few of them are active or have an intact transposon structure. To further define the distribution PLEs in Lepidoptera, where the original active piggyBac IFP2 was discovered, and potentially isolate new functional elements, a survey for PLEs by PCR amplification and Southern dot(More)
