Mitogenomes of genus Pristipomoides, Lutjanus and Pterocaesio confirm Caesionidae nests in Lutjanidae

Abstract

In this study, the complete mitochondrial genome of Goldbanded jobfish (Perciformes: Lutjanidae: Etelinae: Pristipomoides multidens) was sequenced using long-PCR amplification (Accession No.: KF430626). The mitochondrial genome is highly homologous to those of other teleosts. Consensus tree based on phylogeny analysis of nucleotide sequences using the protein-coding regions combined sequences (apart from ND6) in 11 species supports the fact that Pristipomoides multidens of Etelinae and the cluster of Subfamily Lutjaninae remain the sister relationship, consistent with the traditional taxonomy, while the fusiliers (Pterocaesio tile) of family Caesionidae nested within the genus Lutjanus of family Lutjanidae and showed more closely relationship with the non-reddish snappers cluster including L. russellii and L. argentimaculatus. Conclusively, this mitogenomic phylogeny indicates that the Caesionidae is a synonym of family Lutjanidae. Given the morphologic and feeding diversity, we hypothesize that the variation of feeding systems of genus Lutjanus may drive the speciation of snappers and fusiliers.
