Identification and phylogenetic analysis of the mitochondrial genome of Hemibarbus labeo BML (Cypriniformes: Cyprinidae)

The complete mitochondrial genome ofHemibarbus labeoBML (Cypriniformes: Cyprinidae) is 16,612 bases in length. It consists of 22 tRNA genes, 13 protein-coding genes, 2 rRNA genes, and 1 non-coding region. Its overall nucleotide composition is A: 29.85%, G: 17.07%, T: 25.86%, and C: 27.23%, respectively, with an A + T rich feature (55.71%). The gene arrangement and organization of the mitogenome fromH. labeoBML were very similar to other Cyprinidae fishes. The phylogenetic analysis showed thatH. labeoBML clustered in genus Hemibarbus. These results will contribute to the taxonomy and conservation biology studies ofH. labeo.
