Phylogenetic relationships of mullets (Mugilidae) in China Seas based on partial sequences of two mitochondrial genes

Phylogenetic analyses of Mugilidae species from the China coast were carried out based on 16S and 12S rRNA mitochondrial gene sequences by maximum parsimony maximum likelihood Bayesian inference and neighbor joining analysis in the present study The results suggested that Mugil cephalus is the most genetically divergent species among the Mugilidae The four Liza species clustered together and formed a monophyletic group The genera Osteomugil showed closer affiliation with Valamugil than with Ellochelon these three genera then grouped together to form a monophyletic clade presenting as the sister group to Liza Analyses of phylogenetic and genetic distance indicated that Southern and Northern lineages of Liza haematocheila may be two different species likewise strong genetic divergence existed between Southern and Northern M cephalus lineages In addition our results supported the Southern origin of Chinese Mugilids which is contrary to the hypothesis based on morphological characters (C) 2010 Elsevier Ltd All rights reserved
