Fig. 4: Recombination of genetic modules between virus families infecting the same host.
From: Entamoeba and Giardia parasites implicated as hosts of CRESS viruses

Phylogenetic maximum-likelihood trees of viral Rep and Cap proteins, scale bars refer to amino acid substitutions per site, numerical values represent bootstrap support. Lines connect genes from the same virus or physically close endogenous viral genes. Pictograms of Entamoeba (tetranucleate cyst stage) and Giardia (flagellated trophozoite stage) are shown to indicate virus host. CCA =Â CRESS virus Cap assemblage.
