Genomic, Proteomic, Morphological, and Phylogenetic Analyses of vB_EcoP_SU10, a Podoviridae Phage with C3 Morphology
Figure 5
Phylogenetic tree showing the relationship of the two structural proteins, the scaffold protein and the head protein, within and between the two morphotypes.
Phages SU10, NJ01, PhiEco32, GAP52, 7–11, and KSP100 belong to the C3 morphotypes (elongated capsid), and phages tf, UVF-P2, LUZ24, PaeP-p2-10, MR299-2, and PaP3 to the C1 morphotype (icosahedral capsid). The tree was inferred by using the Maximum Likelihood method based on the Whelan and Goldman model [23]. The tree with the highest log likelihood (−9785.9307) is shown. A maximum parsimony (MP) tree was used as an initial tree in the heuristic search. The tree is drawn to scale, with branch lengths measured in the number of substitutions per site. The analyses were conducted in MEGA6 [21].
