The complete mitochondrial genome of striped large-eye bream, Gnathodentex aureolineatus (Teleostei, Lethrinidae)

Striped large-eye bream, Gnathodentex aureolineatus (Lacepede, 1802), is of high economic value and has important ecological functions in coral reefs. However, the genetic information of this species is quite limited, and there is taxonomical difficulty in the family Lethrinidae. Here, we present the complete mitochondrial genome of G. aureolineatus obtained with a long PCR approach and Sanger sequencing. The mitogenome was 16,940 bp in length, consisting of 37 genes (13 protein-coding genes, two ribosomal RNA genes, and 22 transfer RNA genes) and two non-coding regions. Both maximum-likelihood and Bayesian inference phylogenetic trees placed the genus Gnathodentex sister to Monotaxis within Lethrinidae. These results contribute toward the taxonomy, conservation, and phylogeny of Lethrinidae.

Automated summary

In this study, the complete mitochondrial genome of the striped large-eye bream, Gnathodentex aureolineatus, was obtained using a long PCR approach and Sanger sequencing. The genome was 16,940 bp in length and consisted of 37 genes, including protein-coding genes, ribosomal RNA genes, and transfer RNA genes. Phylogenetic analysis revealed that the genus Gnathodentex is closely related to Monotaxis within the family Lethrinidae. These findings provide valuable information for the taxonomy, conservation, and phylogeny of Lethrinidae.
