Comparative genomic analysis of M.auratus. A Consensus phylogenetic tree of M.auratus (Syrian hamster) and other mammalian species based on 6,620 single-copy genes. The divergence time are marked in each note with an error range. B Venn diagram of M.auratus gene families with M. musculus, C. griseus and M. ochrogaster. C Gene family expansions and contractions in the M.auratus genome. The numbers on each branch correspond to the numbers of gene families that have expanded (green) and contracted (red). MRCA: most recent common ancestor. D KEGG pathway enrichment of unique gene families in the M.auratus genome
