Abstract
The Leiocassis crassilabris is an important economic fish in China, and is widely distributed in south China, e.g. Yangtze River, Pearl River, and Min River, so it is a good model to study population genetics and geological changes of these regions. In this study, the complete mitochondrial genome sequence of L. crassilabris has been obtained with PCR. The gene arrangement and composition L. crassilabris of mitochondrial genome sequence are similar to most of the other vertebrates’, which contains 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes and a non-coding control region with the total length of 16,530 bp. Except for eight tRNA and ND6 genes, other genes are encoded on heavy-strand (H-strand). Similar to most other vertebrates, the bias of G and C have universality in different region (genes). The complete mitochondrial genome sequence of L. crassilabris would contribute to better understand population genetics, conservation, biogeography, evolution of this lineage.
