An insert in the Hpy region of hscp in Heliothis virescens (Lepidoptera: Noctuidae) reveals a possible CORE-SINE of insects

초록

A new putative transposon was identified in the tobacco budworm, Heliothis virescens. This transposon was characterized as a full length CORE-SINE (65 bp of "CORE" core specific nucleotide short interspersed elements) that resembled sequences from three other lepidopterans and humans. In particular, the A-box and B-box regions of this sequence most closely conformed to the signature of CORE-SINEs from widely divergent species. This CORE-SINE was present as a polymorphism in a hypervariable region of the gene hscp, which is the target of pyrethroid insecticides and other xenobiotics in the nerve axon. We described this new putative transposon as Noct-1 due to its presence in a noctuid moth. This is the first description of a full-length CORE-SINE with the A-box, B-box, target site duplication, and candidate core domain from an insect.
