Abstract
In this study, we cloned and sequenced the complete mitochondrial genome of Odontobutis sinensis. The genome was found to be 17,441 bp in size with a mostly conserved structural organization when compared with that of other teleost fish. It contained 37 genes (13 protein-coding genes, 22 transfer RNA genes and two ribosomal RNA genes) and two main non-coding regions (the control region and the origin of the light strand replication). Rearrangements of tRNAs (tRNA-Ser, tRNA-Leu, tRNA-His) and three additional longer non-coding regions (51 bp, 622 bp and 66 bp, respectively) were present between the ND4 and ND5 genes. Within the control region, one 322 bp long tandem repeat area (7*46 bp) and some typical conserved domains were identified. The molecular data here we presented could play a useful role to study the evolutionary relationships and population genetics of the Odontobutidae.
