Abstract
In this study, the complete mitochondrial genome of Chionodraco rastrospinosus was obtained, which was 17598 bp including 2 ribosomal RNAs, 13 protein-coding genes, 22 transfer RNAs, and a non-coding control region. The length of D-loop was 1332 bp and its contents of A, T, C, and G were 30.3%, 27.6%, 26.8%, and 15.3%. The complete mtDNA sequences of C. rastrospinosus and other 14 species were used to reconstruct the phylogenetic tree, suggested that C. rastrospinosus was closest to two species of Chionodraco. The study would provide a basic data for further research on population structure, conservation genetics and molecular evolution of C. rastrospinosus.
