Complete mitochondrial genome of the Asian pencil halfbeak Hyporhamphus intermedius (Beloniformes, Hemirhamphidae)

Abstract

The complete mitochondrial genome of Hyporhamphus intermedius was determined to be 16,720 bp in length with (A + T) content of 56.3%, and it consists of 13 protein-coding genes, 22 tRNAs, two ribosomal RNAs, and a control region. The gene composition and the structural arrangement of the H. intermedius complete mtDNA were identical to most of the other vertebrates. Interestingly, two tandem repeat units were identified across tRNA-Pro and control region (2*41 bp), while in most of the fishes the tandem repeat units are located in the control region. The molecular data we presented here could play a useful role to study the evolutionary relationships and population genetics of Hemirhamphidae fish.
