摘要

Abstract

Partial sequences of 12S rRNA gene of eight snappers collected in coastal waters of china determined in the present study and two lutjanid sequences downloaded from GenBank were combined to reconstruct Maximum likelihood and Bayesian inference trees with Siganus unimaculatus, S. fuscescens, Monotaxis grandocu/is, Lethrinus obsoletus (perciformes), Myripristis berndti, Beryx splendens, Sargocentron rubrum (Beryciformes), and Danio rerio(Cypriniformes) as outgroups. Totally 170 variable sites and 126 parsimony-informative sites existed in the 895 bp sequences, and the ts/tv ratio was 2.39. Phylogenetic trees showed that the Caesioninae were nested within the Lutjaninae, supporting the recent opinion that the Caesionidae shoud be regarded as a synonym of the Lutjanidae, but their phylogenetic relationships to other lutjanid species remained to be further studied. L. malabarius and L.sebae formed a well-supported clade, supporting the taxonomical treatment of L. malabarius and L. sebae based on morphological characters; however morphologically similar species L. johni and L. argentimaculatus were genetically quite different, indicating that morphologically similar species were not necessarily genetically closely related.
