Abstract
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.
