Complete mitochondrial genome of squaretail coralgrouper Plectropomus areolatus (Perciformes, Epinephelidae)

Abstract

The complete mitochondrial genome (mitogenome) sequence of squaretail coralgrouper Plectropomus areolatus was determined with long PCR approach. The genome was 16,770 bp in length and contained 13 protein-coding genes, 22 transfer RNAs (tRNAs), 2 ribosomal RNAs (rRNAs), and 2 non-coding regions, with the gene content and order being similar to most other teleosts. The overall base composition of the mitogenome was estimated to be 28.81% A, 27.63% T, 27.24% C, and 16.33% G, with a high AT content of 56.44%, indicating an obvious anti-guanine bias commonly observed in fishes. It shared 90.7%, 78.8%, and 78.7% mitogenome sequence with Plectropomus leopardus, Epinephelus moara, and Epinephelus coioides, respectively.
