The Complete Mitochondrial Genome of Plectorhinchus Chaetodonoides (Perciformes: Haemulidae)

Abstract

Plectorhinchus chaetodonoides Lacepède, 1801 is a widespread multicolored sweetlips fish found in the Indo-West Pacific Ocean where its appearance and color patterns drastically change during growth. In this study, the whole mitochondrial genome of P. chaetodonoides was sequenced which revealed it is 16,546 bp long and contains 13 protein-coding genes, 22 transfer RNA (tRNA) genes, two ribosomal RNA (rRNA) genes, and one noncoding regulatory region. The GC content of the whole genome was 47.5% and 48.2%, 46.3%, 46.8%, 42.5% in the protein coding genes, tRNAs, rRNAs, and control regions, respectively. Molecular phylogenetic analysis resolved P. chaetodonoides as closely associated with Diagramma pictum and nested within a clade of Haemulidae that is allied with species from the Lutjanidae, Kyphosidae, Teraponidae, and Sciaenidae families. These results provide an essential genomic resource for future evolutionary and conservation studies of P. chaetodonoides as well as the Haemulidae family.
