Abstract
In this study, the complete mitochondrial genome of a hybrid, which was produced by sexual hybridization of Leiocassis longirostris (♀) and Pelteobagrus fulvidraco (♂), was obtained. The complete mitochondrial genome is 16 534 bp in length, including the typical structure of 22 transfer RNA genes, 13 protein-coding genes, 2 ribosomal RNA genes and the non-coding control region. Twenty-one site differences were found in overall length compared with the known mitochondrial sequence of L. Longirostris. About 2 site differences were located in rRNAs, 1 in tRNA, 4 in the control region and 14 in protein-coding genes. Furthermore, 14 variable bases of the protein-coding regions resulted in five variable amino acids, which were located in the ND1, ND2, COX3, ND4 and ND5, respectively.
