Complete mitochondrial genome of Ochetobius elongatus (Cyprinidae, Leuciscinae)

Abstract

In this study, the complete mitochondrial genome of Ochetobius elongatus was first sequenced and annotated. The entire mitogenome is 16 613 bp in length and has a typical vertebrate mitochondrial genetic trait, consisting of 13 protein-coding genes, 22 transfer RNA genes, 2 ribosomal RNA genes and a control region. The overall nucleotide composition of O. elongatus mt genome is A: 30.96%, T: 25.38%, G: 16.26% and C: 27.40%, with the A + T content of 56.34%, showing an obvious anti-G bias. Phylogenetic analyses suggest that Leuciscinae formed a clade first and then clustered with Cultrinae. The complete mitochondrial genome of O. elongatus will benefit to a better understanding of population genetics, molecular systematics and stock evaluation, further serving the germplasm resources conservation and management of O. elongatus.
