Project description:The complete mitochondrial genome of Gerres filamentosus was sequenced by high throughput sequencing method. Length of this genome is 16,795 bp, containing 13 protein-coding genes, 22 tRNA genes, two rRNA genes and one large non-coding region. ND6 and eight tRNA genes are encoded by L-strand, and others are encoded by H-strand, which is similar to those in most vertebrates. Phylogenetic tree based on 13 protein-coding genes shows that the clade of G. filamentosus is closely clustered with that of Gerres oyena, and families Caproidae and Ephippidae have the closest relationship to Gerridae, comparing with Sillaginidae.
Project description: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.
