Abstract

The complete mitochondrial genome (mitogenome) was determined for the longfin dragonfish Tactostoma macropus, which is the first for the genus and the third within the family Stomiidae. The mitogenome sequence is 17,690 bp in length containing 2 ribosomal RNA genes, 22 transfer RNA genes, 13 protein-coding genes, and a control region, as in most fishes. The gene order of T. macropus showed an unreported deviation from the typical vertebrate one. Phylogenetic reconstruction using the maximum likelihood method placed T. macropus in the monophyletic Stomiiformes. Three stomiid species were recovered as a moderately supported clade in the phylogenetic tree.

Keywords: Deep-sea; gene rearrangement; mitogenome; pelagic fish.

Maximum likelihood (ML) phylogeny of 10 teleost fishes according to the concatenated amino-acid sequences of 13 protein-coding genes (3784 positions). Tactostoma macropus is shown in bold. Sequences were aligned separately for each gene using MAFFT version 7.047 (Katoh and Standley 2013) with default parameters. Ambiguously aligned positions were removed using Gblocks Server version 0.91b (Castresana 2000), with all options for less stringent selection. ML analysis was performed in RAxML version 7.2.6 (Stamatakis 2006) using mtREV + G model; nodal support was estimated by 1000 bootstrap replicates. DDBJ/EMBL/GenBank accession numbers are shown for published sequences.
