The complete mitochondrial genome of Triplophysa erythraea (Huang et al. 2019) (Cypriniformes, Nemacheilidae)

Abstract

In this study, the complete mitochondrial genome of Triplophysa erythraea was determined for the first time. Results showed the mitogenome was 16 565 bp, including 2 ribosomal RNA genes, 22 transfer RNA genes, 13 protein-coding genes and 2 non-coding regions. The overall base composition of its mitochondrial genome was 28.9% A, 25.2% T, 28.7% C and 17.2% G. Phylogenetic tree revealed that Triplophysa erythraea had the closest relationship with Triplophysa xiangxiensis, which was also found in Xiangxi Tujia and Miao Nationality Autonomous Prefecture, Hunan province. In general, this study provided valuable information for conservation genetics analyses of Triplophysa erythraea and further displayed the evolution of species within the genus Triplophysa.
