Characterization of the complete mitochondrial genome of the coral reef fish, Hemigymnus melapterus (Pisces: Labridae) and its phylogenetic implications

Characterization of the mitochondrial genome of parupeneus indicus (perciformes, mullidae)

Parupeneus indicus, a species in the family Mullidae, inhabits the coastal and inner lagoon reefs of the Indian and Pacific oceans. The mitochondrial genome of P. indicus is 16,566 base pairs in length and contains 13 protein-coding genes (PCGs), 22 transfer RNA (tRNA) genes, two ribosomal RNA (rRNA) genes, and a D-loop control region. The overall base composition is 26.58% A, 24.83% T, 30.39% C, and 18.19% G, indicating an AT-rich profile (51.41%). Phylogenetic analysis based on the 13 PCGs revealed a close evolutionary relationship between P. indicus and P. barberinus. The data obtained in this study represent a valuable mitogenomic resource for population studies in the family Mullidae and will contribute to gaining a better understanding of the conservation genetics and environmental DNA of these fish.

Characterization of the mitochondrial genome of Favonigobius reichei (Perciformes, Gobiidae)

Favonigobius reichei, belongs to the family Gobiidae, which is widely distributed in estuarine and marine waters of the coasts of the Indian and the western Pacific Oceans. The entire mitochondrial genome of F. reichei is 16,415 base pairs (bp) in length and contained 13 protein-coding genes (PCGs), 2 ribosomal RNA (rRNA) genes, and 22 transfer RNA (tRNA) genes. The overall base composition is 27.71% A, 26.78% T, 28.02% C, and 17.49% G, showing AT-rich feature (54.49%). Phylogenetic analysis based on 13 PCGs shows the F. reichei has the closest evolutionary relationship with Myersina macrostoma. This work provides a valuable mitogenome resource for better understanding of the conservation genetics, environmental DNA, and population studies in the family Gobiidae.
