Identification of Type II Interferon Receptors in Geese: Gene Structure, Phylogenetic Analysis, and Expression Patterns

Figure 6

Phylogenetic analysis based on IFNGR1 and IFNGR2 amino acids. The phylogenetic tree of partial vertebrate IFNGR1 and IFNGR2 amino acid sequences was constructed using the NJ method in MEGA5. Numbers at branch nodes indicate the confidence level with 1000 bootstrap replications. IFNGR1 and IFNGR2 of birds are indicated with a green oval, and those of geese are indicated with red circles.
