Particular gene order and complete mitochondrial genome of Ariosoma meeki (Congridae, Ariosoma)

Ariosoma meeki (A. meeki) is a demersal and carnivorous fish species belongs to the family Congridae. Some wild populations of A. meeki are in danger because of the overfishing and environmental pollution. In order to better understand the germplasm resources, the complete mitochondrial genome of A....

Sumario:Ariosoma meeki (A. meeki) is a demersal and carnivorous fish species belongs to the family Congridae. Some wild populations of A. meeki are in danger because of the overfishing and environmental pollution. In order to better understand the germplasm resources, the complete mitochondrial genome of A. meeki was firstly determined in this study. The complete mitochondrial genome is 16,404 nucleotides, comprising 12 protein-coding genes, 2 ribosomal RNA genes, 20 tRNA genes, and 2 main non-coding regions, but ND6 and two tRNA genes were not found in the A. meeki mitogenome. The A. meeki mitogenome was currently the first member of Ariosoma genus with gene and tRNA deletion. In addition, phylogenetic analysis result demonstrated that A. meeki and A. shiroanago were clustered in a clade and formed a sister relationship.
