Complete genome sequence of the mitochondrial DNA of the river lamprey, Lethenteron japonicum

Mitochondrial DNA. 2015;26(6):863-4. doi: 10.3109/19401736.2013.861432. Epub 2014 Jan 10.


Lampreys are eel-like jawless fishes evolutionarily positioned between invertebrates and vertebrates, and have been used as model organisms to explore vertebrate evolution. In this study we determined the complete genome sequence of the mitochondrial DNA of the Japanese river lamprey, Lethenteron japonicum, using next-generation sequencers. The sequence was 16,272 bp in length. The gene content and order were identical to those of the sea lamprey, Petromyzon marinus, which has been the reference among lamprey species. However, the sequence similarity was less than 90%, suggesting the need for the whole-genome sequencing of L. japonicum.
