Figure 4. — Phylogeny of the Astroviridae based on the non-structural polyprotein sequence (alignment length of 733 amino acids). Viruses obtained in this study are shown in blue and have a ‘+’ after their name. Related viruses are shown in black. Virus abundance is expressed as the percentage of the total number of reads and represented by the size of each coloured symbol. The colour of each symbol refers to the site type. Black circles on nodes show bootstrap support values greater than 90 per cent. Branches are scaled according to the number of amino acid substitutions per site, shown in the scale bar. The tree is midpoint rooted.
