Phylogenetic relationships within tribe Rattini (Muridae: Murinae) based on cytochrome b (A), RAG1 (B), and GHR (C) coding sequences including the nucleotide sequences produced in this study.
All trees were estimated in a maximum likelihood framework. Scale bars denote substitutions per site along the branches. Shown in red and green are the rat sequences obtained in this study. The subtree corresponding to the Rattus species group sensu lato is colored in blue for clarity.
