Phylogenetic tree of the full capsid sequence of norovirus GII.4 variant reference strains

DNA (dist) Kimura phylogenetic tree of GII.4 norovirus full capsid sequence of norovirus GII.4 variant reference strains corresponding to positions 5,085–6,707 (1,623bp) of reference strain GII.4_Sydney_2012 (JX459908). Red highlights the branch containing the potential new variant that has altered slightly and is branching away from the parent strain GII.4_Sydney_2012 (JX459908). The figures on the branches represent bootstrap values (%) after resampling 1,000 datasets. Only bootstrap values ≥ 70% are shown. The scale marker represents substitutions per site.
