FIG 5 .

Maximum-likelihood phylogenetic tree of norovirus genomes belonging to genogroup GI, with the norovirus GII reference genome as an outlier. The nucleotide sequences were aligned with MUSCLE, and the alignment was trimmed to the length of contig 6 of the LE_11-10 virome sequence, resulting in 7,758 positions analyzed for tree building. The maximum-likelihood method was used, with the Tamura-Nei model for nucleic acid substitution. The percentages of trees in which the associated taxa clustered together are shown next to the branches. The scale bar represents the number of substitutions per site.
