Phylogenetic analysis of N, P, M, F, A, and L amino acid sequences of FmoPV. The trees were constructed by maximum likelihood method with bootstrap values calculated from 1,000 trees and rooted on midpoint. The scale bars indicates the branch length that corresponds to 0.5 substitutions per site. Three strains from FmoPV were named as 761U, 776U, and M252A. Names and accession numbers of the other viruses are listed in Table S5.
