Cophylogenetic analysis of rosaviruses and their hosts. The blue branches represent the virus phylogeny, and the black branches represent the host phylogeny. Cospeciation events, duplication events, host switching events, and loss events are labelled with empty circles, filled circles, arrows, and dotted lines, respectively. The sequences and novel host species identified in this study are labelled with blue font and red font, respectively. The corresponding accession number in GenBank for each sequence is shown in Additional file 2.
