(A) Hasegawa–Kishino–Yano plus I phylogenetic tree based on a 300 bp region of the RNA-dependent RNA polymerase region of feline coronavirus (FCV) strains (300 bp). Brazilian FCV sequences (GenBank accession number KM505126- KM505132) and the Brazilian feline norovirus sequences (GenBank accession number KM505133) are shown as filled circles. (B) Hasegawa–Kishino–Yano plus I phylogenetic tree based on the partial gene sequence (550 bp) of RNA-dependent RNA polymerase of norovirus strains. The Brazilian feline norovirus sequence is highlighted (GenBank accession number KM505133). Bootstrap values based on 2000 generated trees are displayed at the nodes (values > 50% are shown). The branch lengths are proportional to the evolutionary distance between sequences and the distance scale in nucleotide substitutions per position is shown.
