Complete mitochondrial genome of brown-banded butterflyfish Chaetodon modestus (Chaetodontiformes, Chaetodontidae) and phylogenetic analysis

The complete mitochondrial genome of the Chaetodon modestus (Temminck and Schlegel, 1844) was first determined in this study, which is 16,490 bp in length, containing 13 protein-coding genes, two rRNA genes, and 22 tRNA. Out of 37 mitochondrial genes, except for ND6 and eight tRNA (Pro, Glu, Ser, Tyr, Cys, Asn, Ala, Gln) genes were encoded on the L-strand, the others were encoded on the H-strand. The overall base composition includes A (28.0%), T (28.7%), G (16.7%), ad C (26.6%). The phylogenetic tree was built using the maximum-likelihood approach to provide a relationship within Chaetodontidae, which might be valuable for species management.

Automated summary

The complete mitochondrial genome of Chaetodon modestus was determined for the first time in this study, revealing its gene length, number of protein-coding genes, and base composition. A phylogenetic tree was also constructed to study the relationship within Chaetodontidae.
