Complete mitochondrial genomes of the anadromous and resident forms of the lamprey Lethenteron camtschaticum

Abstract

The complete mitochondrial genomes were sequenced in anadromous and resident forms of the lamprey Lethenteron camtschaticum. The sizes of the genomes in the two isolates are 16,245 and 16,295 bp. The gene arrangement, base composition, and size of the two sequenced genomes are similar to the lamprey genomes previously published. The total sequence divergence between the two genomes is very low (0.14%), supporting conspecificity of the anadromous and resident forms of L. camtschaticum. Comparison of the genomes sequenced in the present work with other genomes of lampreys available in GenBank, reveals two distinct evolutionary lineages with a genera level of divergence among the lampreys of eastern Eurasia.
