The complete mitochondrial genome of Odontesthes sp. (Atheriniforms, Atherinopsidae)

AbstractIn this study, the complete mitochondrial genome of Odontesthes sp. has been studied first. The genome is 16,528 bp in length and contains 13 protein-coding genes, 22 tRNA genes, 2 ribosomal RNA genes and 1 putative control region. The mitochondrial genome of Odontesthes sp. had common features about gene arrangement and tRNA structures compared with those of other teleost fishes. The overall base composition of Odontesthes sp. is T 27.3%, C 29.4%, A 26.0% and G 17.3%, with a slight A + T bias of 53.3%. Meanwhile, the conserved motif 5′-GCCGG-3′ was determined in the origin of light-strand replication of Odontesthes sp. The mitochondrial genome of this species would play an important role in the phylogenetics of Atherinopsidae.
