FIGURE 6.

Phylogenetic analyses using the RdRP and 3Cpro amino acid sequences from 58 viruses in the order Picornavirales. The phylogenic trees of RdRP (A) and 3Cpro (B) amino acid sequences were constructed using the maximum likelihood method with 1000 bootstraps. Among these 58 viruses, 10 were from Picornaviridae, four from Caliciviridae, two from Solinviviridae, five from Polycipiviridae, six from Marnaviridae, five from Dicistroviridae, five from Iflaviridae, 13 from Secoviridae, seven from unclassified picornaviruses, and one from rice curl dwarf-associated picornavirus (RCDaV). Viruses from the same family are shown in the same color. The name of RCDaV is shown in red. The bottom panel shows the schematic diagram of genome organizations of different families used in this analysis. Virus names and their GenBank or Refseq accession numbers are listed in Supplementary Table 3.
