Fig. 4. (A) Maximum likelihood tree of the concatenation of the 23 conserved genes in T4-like genomes (4,653 residues). Conserved genes are gp4, gp6, gp13, gp14, gp15, gp17, gp18, gp20, gp21, gp22, gp23, gp25, gp32, gp41, gp43, gp44, gp46, gp47, gp53, gp55, gp61, regA, and UvsW. (B) NJ tree of the partial gp23 sequences obtain by PCR based on the 124 most highly conserved residues. The black circles indicate internal nodes with at least 95% bootstrap support. The scale bar represents the number of amino acid substitutions per residue.
