Figure 2. Phylogenetic Analysis of the spike gene.

Figure 2

Phylogenetic analysis of an 1100 nucleotide segment of the S2 region of the spike gene of RM-Bat-CoV 453/2007/EF (Eptesicus fuscus) compared to other known alphacoronaviruses. Phylogenetic trees were constructed by the neighbor-joining method using MEGA version 4.
