Complete mitogenomes of Guinean angelfish (Holacanthus africanus) and Rock beauty (Holacanthus tricolor) (Teleostei: Pomacanthidae).

In this study, we used the next-generation sequencing method to deduce two complete mitogenomes of Guinean angelfish (Holacanthus africanus) and Rock beauty (Holacanthus tricolor) for the first time. The assembled mitogenome, consisting of 16,819 bp and 16,625 bp in length, shows 87% similarity with each other. Both mitogenomes follow the typical vertebrate arrangement, including 13 protein-coding genes, 22 transfer RNAs, 2 ribosomal RNAs genes, and a non-coding control region of D-loop. The D-loop contains 1107 bp in H. africanus and 905 bp in H. tricolor and is located between tRNA-Pro and tRNA-Phe. The overall GC content is 46.2% for H. africanus and 45.6% for H. tricolor. The complete mitogenome of Guinean angelfish and Rock beauty deduced in this study provides essential and important DNA molecular data for further phylogenetic and evolutionary analysis for marine angelfish.
