The complete mitochondrial genome of Thryssa hamiltonii (Engraulinae, Engranlidae, Clupeoidei) and phylogenetic studies of Clupeoidei

Abstract

The complete mitochondrial genome of Thryssa hamiltonii has been determined. The whole sequence was 16,894 bp in length and included 13 protein-coding genes, 22 transfer RNA genes, two ribosomal RNA genes and one control region (D-loop). The overall base composition is A 30.77%, C 27.97%, G 16.25%, T 25.01%, with a slightly A + T bias of 55.78%. With the exception of ND6 and eight tRNA genes, all other mitochondrial genes are encoded on the heavy strand. Three tandem repeat sequences were observed in the control region. Phylogenetic tree was constructed based on 13 protein-coding genes sequences of 21 clupeoidei species, and the result showed that T. hamiltonii is most closely related to T. dussumieri. These mitogenome sequence data will be useful for population genetics and phylogenetic analysis of the Clupeoidei.
