Analysis of the complete mitochondrial genome sequence of Japanese butterflyfish, Chaetodon nippon (Chaetodontiformes, Chaetodontidae)

Japanese butterflyfish (Chaetodon nippon) belong to the family Chaetodontidae and order Chaetodontiformes. It has circular mitochondrial genome of 16,507 bp in length with 55.4% of A + T content and has 37 genes, including 22 tRNA, 2 rRNA, and 13 protein-coding genes, in addition to a control region. The results of phylogenetic analysis indicated that the C. nippon, C. wiebeli, C. auripes, C. auriga, C. octofasciatus, C. speculum, and C. modestus are closely related to each other. The findings of this study will provide useful genetic information for further phylogenetic and taxonomic classifications of Chaetodontidae.

Automated summary

This study investigated the mitochondrial genome of the Japanese butterflyfish (Chaetodon nippon). The genome was found to be 16,507 bp in length with 55.4% A + T content, and contained 37 genes. Phylogenetic analysis revealed a close relationship between C. nippon and six other species. These findings provide valuable genetic information for phylogenetic and taxonomic classifications of the Chaetodontidae family.
