Abstract

Abstract: The complete mitogenomes of two lampreys with complex taxonomic histories, the Korean lamprey ( Lethenteron morii ) and the American brook lamprey ( L. appendix ) were determined. Three-nt length difference between two genomes occurred on tRNA-Ser2 and control region 2. Except for 3 indel sites, there are 58 variable sites between two genomes which occurred on 11 of the 13 protein-coding genes (aside from COX3 and ND3 ) and 2 of rRNAs, tRNAs, control regions and intergenic regions. Among these sites, 15 sites are non-synonymous substitution sites occurred on 8 protein-coding genes including COX1-COX2, ND1-ND2, ND4-ND6 and ATPase6 . Control region 1 contains 4 consecutive 39-nt repetitive strings and a 26-nt repetitive string in control region 2 is repeated 3.8 times in both lampreys. The observed level of similarity between nucleotide sequences (99.62%) implies the Korean lamprey and American brook lamprey are very close relatives and should be assigned into the same taxonomic genus.
