Phylogenetic analysis of the tail tubular protein (gp12) from seven phages in the T7 supergroup. The alignment of whole sequence was used to construct the neighbor-joining tree. The scale bar represents 0.05 fixed mutations per amino acid position. Bootstrap values based on 1000 computer-generated tree are indicated at the nodes.
