Complete mitochondrial genome of the Sternaspis scutata (Sternaspidae, Annelida)

Abstract

IIn this study, the complete mitochondrial genome of the Sternaspis scutata wassequenced. The mitochondrial genome is 15 300 bp in length, containing 13 protein-coding sequences, 2 rRNAs, 21 tRNAs and 1 non-coding region. All these genes are in the heavy strand. Most protein-coding genes begin with an ATG codon, while NAD4L utilize ATT. The common termination codon is TAA, except for atp6 terminated with TAG, and cox2, atp8, nad2, nad6 terminated by incomplete codon T. Seen from the phylogenetic tree, Sternaspis scutata, Pista cristata and Terebellides stroemii from the same Order (Terebellida) clustered into one branch.
