Abstract:
The complete mitochondrial genome sequence of Carangoides equula (Perciformes: Carangidae) was determined. The size of the genome was 16,588 bp and overall base compositions of the sequence were 26.3% of A, 30.3% of C, 25.3% of T and 18.1% of G, showing an obvious anti G bias commonly observed in teleosts. The genome contained 13 protein-coding genes, 22 tRNA genes, 2 rRNA genes, and 2 non-coding regions (the control region and the light strand replication origin). Gene organization and gene order was similar to that observed in most other vertebrates. The initiation codon GTG was detected in the open reading frames of ATPase subunit 6, which was novel for ATP6 gene in Carangidae species. The mitogenome of C. equula shared 84.1% and 84.0% sequence similarity with two other Carangoides species Carangoides malabaricus and Carangoides armatus, respectively. The complete mitogenome sequence data of C. equula could provide useful information for taxonomic and phylogenetics studies.
