The complete mitochondrial genome of Dysomma Anguillare (Anguilliformes, Synaphobranchidae) with phylogenetic consideration

Abstract In this study, the complete mitochondrial genome of Dysomma anguillare was obtained, which was 16,898 bp in length. It consists of 13 protein-coding genes, 2 ribosomal RNA genes, 22 transfer RNA genes, and a non-coding control region. The overall base composition of the genome is 33.19% for A, 22.9% for T, 28.1% for C, and 15.79% for G. In 13 protein-coding genes, two types of initiation codon (GTG, ATG) and five types of stop codons (AGG,TAA,TAG,TA, and T) were identified. The phylogenetic tree, which is based on complete mtDNA sequences, suggested that D. anguillare was closest to some species of Synaphobranchidae. This study could provide some basic information for further studies on population structure and molecular evolution of D. anguillare.
