Mitochondrial genome of Psenopsis anomala (Pacific rudderfish) and structure schema comparison of control region in Stromateoidei

Abstract

In this study, the complete mitochondrial genome of Psenopsis anomala (Perciformes, Centrolophidae) was first determined. The mitochondrial DNA was 16,509 base pairs in length. The overall base composition of P. anomala is A 28.4%, C 27.5%, G 16.6% and T 27.5%, with a slight A + T bias of 55.9%. It consists of 22 tRNA genes, 2 ribosomal RNA genes, 13 protein-coding genes and 2 main non-coding regions (the origin of the light strand replication and the putative control region), in which the genes structure and order are similar to most other vertebrates. These mitogenome sequence data would play an important role in population genetics and phylogenetic analysis of the Centrolophidae.
