Complete mitochondrial genome of the river lamprey, Lampetra japonica (Petromyzontiformes, Petromyzonidae)

Abstract

The complete mitochondrial genome was sequenced from the river lamprey, Lampetra japonica. The genome sequence was 16,267 bp in size, and the gene order and contents were identical with the genera Lampetra reissneri. However, L. japonica has two control regions with different mitochondrial genomic organization compared to other previously reported fish mitochondrial genomes. Of 13 protein-coding genes (PCGs), 1 gene (CO1) had incomplete stop codon. The base composition of L. japonica showed anti-G bias (4.65%) on the third position of PCGs.
