Characteristics of the complete mitochondrial genome of Gerres limbatus (Cuvier, 1830) (Perciformes: Gerreidae).

ABSTRACT

The saddleback silver-biddy Gerres limbatus (Cuvier 1830) is distributed in Indo-West Pacific Oceans and associated with shallow coastal marine waters and estuaries. In this study, the complete mitochondrial genome of G. limbatus was firstly documented, which is 16,730 bp in length, including 13 protein-coding genes, 22 transfer RNA genes and 2 ribosomal RNA genes. The overall base composition of the mitochondrial genome is 26.42% A, 28.68% C, 27.32% T, and 17.58% G. The Maximum Likelihood phylogenetic tree was constructed based on COI gene of the 31 species from the family Gerreidae, with Heteroclinus puellarum and Hypopterus macropterus as outgroups. It revealed that G. erythrourus was placed as the sister group to G. limbatus.
