a Phylogenetic tree based on partial ORF1 nucleotide sequences of HEVs (4392 bp). b Phylogenetic tree based on partial RdRp nucleotide sequences of unclassified RNA viruses (1014 bp). Phylogenetic trees were constructed by the maximum likelihood method using the best-fit models (GTR + G for HEV, and GTR + G for unclassified RNA viruses). All viruses found in this study are labeled in red. Host genus and location of each virus are labeled by the 5-point stars and dots of different colors. The outer color rings represent additional taxonomic information about these viruses
