Revisiting Coleoptera a + T-rich region: structural conservation, phylogenetic and phylogeographic approaches in mitochondrial control region of bioluminescent Elateridae species (Coleoptera).

The control region (CR) or A + T-rich region in Coleoptera mt genome is poorly characterized, including the Elateroidea bioluminescent species. Here, we provided the first attempt to characterize and compare the structure and organization of the CR of different species within Elateridae. We also revisited some sequenced Coleoptera CR and observed consensus T-stretches, non-conserved sequences near the stem-loop and unusual inner tRNAs-like sequences.
