title: The complete mitochondrial genome sequence of Eleutheronema tetradactylum (Mugiliformes: Polynemidae) and phylogenetic studies of Mugiliformes.
abstract: To date, there has been much disagreement concerning the taxonomic status of Eleutheronema. In this study, the complete mitogenome sequence of Eleutheronema tetradactylum was determined and a Maximum Likelihood (ML) tree was constructed based on concatenated nucleotide sequences of 12 mitochondrial protein-coding genes. The complete mitogenome sequence is 16 490 bp in length, containing 13 protein-coding genes, two rRNA genes, 22 tRNA genes, a putative control region (CR), and a light-strand replication origin (OL). The overall base composition is 27.1% A, 26.0% T, 29.9% C, and 17.0% G, with a slight AT bias (53.1%), similar to most teleostean fishes. All protein-coding genes share the start codon ATG, except for COI, which begins with GTG. Most of them have TAA or TAG as the stop codon, while COII uses AGA, ND4 uses AGG and Cytb uses an incomplete stop codon T--. These results are expected to provide useful molecular data for phylogenetic studies of Polynemidae and Perciformes.
