Fig 1. Phylogenetic tree of nucleotide sequences (336 bp fragment) from the RNA-dependent RNA polymerase (RdRp) gene of 20 FeAstV strains identified in this study (▲) and 11 FeAstVs and 11 other mamastroviruses reference sequences obtained from GenBank.

The tree was constructed using the neighbor-joining method with 1,000 bootstrap replicates in MEGA 7.0 software.
