Complete mitochondrial genome and phylogenetic analysis of (Teleostei, Cypriniformes, Cyprinidae).

In this study, we aimed to sequence and annotate the complete mtDNA genome sequence of , which were collected from Luosuojiang River in Menglun area, Yunnan Province, China. The mitochondrial genome was 16,592 bp in length, comprising 13 protein-coding genes (PCGs), 22 transfer RNA genes (tRNAs), two ribosomal RNA genes (rRNAs), and two non-coding regions (origin of L-strand replication and control region). The whole genome contained C (26.5%), A (32.5%), T (25.3%), and G (15.7%), with an obvious A + T bias (57.8%). Based on the concatenated amino acids sequences of 13 PCGs of and other 22 fishes, a phylogenetic tree was reconstructed using the maximum-likelihood method. The result of phylogenetic analysis supported a close relationship between and . The fundamental genetic data of would be useful for conservation and phylogeny.
