Mitochondrial genome of Acrossocheilus parallens (Osteichthyes: Cyprinidae).
Genus Acorssocheilus includes approximately 24 valid species, 19 of which are endemic to China. The complete mitogenome of A. parallens is 16,588 bp long and includes 13 protein-coding genes, 22 tRNA genes (ranging from 67 bp in tRNA(Cys) to 76 bp in tRNA(Leu) and tRNA(Lys)), 2 rRNA genes (955 bp in 12S rRNA and 1675 bp in 16S rRNA), and 1 control region (CR). Only ND6 and other eight tRNA genes are encoded on the L-strand while most of these genes are located in the H-strand. Resolving taxonomic uncertainties and defining evolutionary divergence in this genus are important contributions to cladogenesis in cyprinid fishes in East Asia.
