Mitochondrial genome of Silurus asotus (Teleostei: Siluriformes).

The complete mitogenome sequence of the Amur catfish Silurus asotus was determined using long PCRs. The genome was 16,528 bp in length and contained 13 protein-coding genes, 2 rRNA genes, 22 tRNA genes, and 1 control region; the gene composition and order of which was similar to most other vertebrates. The overall base composition of the heavy strand is 30.5% A, 25.8% T, 28.0% C, and 15.8% G, with an AT content of 56.3%. The mtDNA sequence of S. asotus shared 93.6% and 90.6% sequence identity with that of Silurus meridionalis and Silurus glanis. This mitogenome sequence data would play an important role in silurid catfish phylogenetics and siluriform catfish systematics in general.
