Fig. 1.

Genome organization and phylogenetic analysis of gyroviruses in different clades. A) Genome organization of chicken anemia virus, gyrovirus 5, and northern fulmar gyrovirus. B) Phylogenetic trees generated with VP1 and VP2 protein sequences of representative gyroviruses (GenBank accession numbers are shown in Table 1). The scale indicates amino acid substitutions per position. Bootstrap values >60 % are shown. The square and triangle indicate that the virus was initially discovered in blood/tissue and feces/skin swab, respectively
