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

Abstract

The complete mitochondrial genome of Thryssa setirostris has been determined. The whole sequence was 16,926 bp in length and included 13 protein-coding genes, 22 transfer RNA genes, 2 ribosomal RNA genes, and 1 control region (D-loop). The overall base composition is A 29.88%, C 29.23%, G 16.77%, T 24.02%, with a slightly A + T bias of 54%. With the exception of ND6 and eight tRNA genes, all other mitochondrial genes are encoded on the heavy strand. Phylogenetic tree was constructed based on 13 protein-coding genes sequences of 21 clupeoidei species, and the result showed that T. setirostris is most closely related to T. dussumieri. These mitogenome sequence data will be useful for population genetics and phylogenetic analysis of the Clupeoidei.
