The mitochondrial genome of Spualiobarbus curriculus of Pearl River.

Spualiobarbus curriculus is an important economic species in China. In this study, the complete mitochondrial genome of S. curriculus collected from three parts of Pearl River is cloned and analyzed. The complete sequence includes 22 tRNA genes, two rRNA genes, 13 protein-coding genes, and a D-loop region. The composition of nucleic acid is calculated and it is similar to the known S. curriculus mtDNA. The diversities of sequences and the phylogenetic tree approve that there is high similarity with the one of Yangtze, but there is geographic differences between the sequences. The complete mtDNA genome sequence would contribute to studying phylogenetics in S. curriculus and gemplasm protection of aquatic animal in Pearl River.
