title: Characteristics and phylogenetic studies of complete mitochondrial DNA based on the ricefield eel (Monopterus albus) from four different areas.
abstract: In this study, we cloned and sequenced the complete mitochondrial DNA of ricefield eel populations from four different areas (Guizhou province, Guangxi province, Hunan province, and Guangdong province) in China. The mitochondrial genome was 16,622 bp in length and deposited in the GenBank with accession numbers KP779622-KP779625. The organizations of the complete mitogenomes of the four ricefield eel were similar to those of other teleost species which contained 13 protein-coding genes, two rRNA genes, and 22 tRNA genes, as well as a putative control region (CR). Most of these genes were encoded on the H-strand, except for the ND6 and eight tRNA genes, all other genes were encoded on the H-strand. Phylogenetic analyses using N-J computational algorithms showed that the ricefield eel was clustered with Mastacembelus armatus (KJ184553) and they belong to Synbranchiformes. The four ricefield eel populations could be divided into two groups: Guangxi province and the other population cluster together.
