Complete mitochondrial genome of Lophius litulon (Lophiiforms, Lophiidae) and comparison of light strand replication origin in Lophiidae

Abstract

In this study, the complete mitochondrial genome of yellow goosefish Lophius litulon (L. litulon) was determined. The genome was 16,431 bp in length, and comprised 13 protein-coding genes, 2 ribosomal RNA gene and 22 transfer RNA genes, with 2 main non-coding regions. Its gene order and composition was similar to most of the vertebrates. The overall base composition of L. litulon was 28.6% A; 29.1% C; 16.8% G; 25.5% T, with a slight AT bias of 54.1%. The origin of L-strand replication in L. litulon was located in a cluster of five tRNA genes (WANCY). Motif TCCGG was found in the origin of light strand replication (O_L) of L. litulon, which was common in other mitogenome of Lophiidae. This mitogenome data would play key role in future studying phylogenetic analysis of the Lophiidae.
