Abstract:Anew study on the molecular phylogeny of musk deer was carried out using different genes, species and methods. When the mitochondrial 16S rRNA, Cyt b gene and their combined sequence were used to reconstruct the phylogenetic trees, the results suggested the Moschidae share a closer relationship with cervids than bovids. When the coding sequence of INF-γ gene coming from forest musk deer and other 13 species was used to reconstruct the phylogenetic trees, the topological structure of the NJ tree also suggested that the Moschidae share a closer relationship with cervids than bovids, while the MP tree suggested the Moschidae was closer with bovidae. When the 12 heavy-strand protein-coding genes of forest musk deer and other 17 species of cetartiodactylans was used to reconstruct the phylogenetic relationships, the results indicated that the Moschidae was most closely related to Cervidae, which was not consist with the study we had done using 23 species of cetartiodactylans, whose trees confirmed Moschidae was a sister group to Cervidae/Bovidae. This might attribute to close relative, short divergence time between these species, and insufficient phylogenetic information and different mutation rate in some gene sequence for Moschidae, cervids and bovids. Therefore, more studies are needed in the future to unambiguously resolve the molecular phylogenetic position of musk deer.
