The complete mitochondrial genome of Eleutheronema rhadinum was determined, revealing a potential molecular marker for species identification. Phylogenetic analysis showed a close clustering of species in the family Polynemidae.
The complete mitochondrial genome of Eleutheronema rhadinum was determined for the first time. The E. rhadinum mitogenome was 16,718 bp in length, comprising 13 protein coding genes (PCGs), 2 ribosomal RNAs (rRNAs), 22 transfer RNAs (tRNAs), 1 control region (CR), and 1 L-strand replication origin (O-L). The genome organization, and base composition were similar to other teleosts. An additional non-coding region detected in the HSL cluster, was with significant similarity to the nearby tRNA-Leu (CUN), which could be a useful marker for identifying E. rhadinum and Eleutheronema tetradactylum. Furthermore, phylogenetic analysis showed species in the family Polynemidae were well clustered together. But sister relationships between Polynemidae and Sciaenidae, Menidae plus Lactariidae were refused by present study.
