The complete mitochondrial genome of Arius arius (Siluriformes: Ariidae)

摘要

The threadfin sea catfish (Arius arius ) belongs to the genus Arius in Ariidae. In this paper, we initially determined the complete mitochondrial genome of Arius arius . The mitochondrial genome is 16, 711?bp in length, with the base composition on the heavy strand: A – 29.67%, T – 25.38%, C – 29.70% and G – 15.25%. It has the typical vertebrate mitochondrial gene arrangement, including 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes and a control region. Phylogenetic analysis showed that A. arius was clustered into the order of Siluriformes, and closely related to species in the family of Siluridae. The present study would contribute to genetic resources conservation and systematics study of A. arius .
