Abstract:
To better understand the phylogenetic status of the Sheatfish, Pterocryptis cochinchinensis, we determined its complete mitogenome sequence using polymerase chain reaction and the direct sequencing method. The complete mitogenome sequence was 16,501bp in length and contained 13 protein-coding genes, 2 rRNA genes, 22 tRNA genes, and 1 control region (D-loop), the gene was identical to typical vertebrate. This was the first report of the complete mitogenome sequence in genus Pterocryptis. Phylogenetic based on mitogenome sequences and cytb gene suggested that the Sheatfish formed the most basal branch having sister relationship with the clade containing all other analyzed genus Silurus fishes.
