The complete mitochondrial genome of Schizopygopsis pylzovi (Teleostei, Cyprinidae, Schizopygopsis)

Abstract

Schizopygopsis pylzovi, an endemic species in the Qinghai-Tibetan Plateau, has a unique ability to adapt to the extreme ecological condition of the plateau. In this study, we successfully sequenced the first mitochondrial genome of S. pylzovi. The mitogenome is 16,814 bp in length, containing 13 protein-coding genes, 2 rRNA genes, 22 tRNA genes and a control region (D-loop). The overall base composition of the heavy strand (H-strand) is 28.3% A, 26.1% C, 18.6% G, and 27.0% T, with a slight AT bias of 55.3%. Most of the genes are encoded on H-strand, except for eight tRNAs (tRNA^Gln, tRNA^Ala, tRNA^Asn, tRNA^Cys, tRNA^Tyr, tRNA^Ser, tRNA^Glu and tRNA^Pro) and ND6 genes.
