Sequence comparison, genomic organization, and phylogenetic analysis of the novel picornaviruses identified in red-crowned cranes. (a) Phylogenetic analysis based on the complete amino acid sequence of P3 proteins of gapovirus, grusavirus, and 35 representative strains of all 35 genera of the family Picornaviridae. The virus indicated by a solid black circle was from the wild group, and the one marked with an unfilled black circle was from the ornamental group. (b) Phylogenetic analysis based on the complete amino acid sequences of P1 proteins of gapovirus, grusavirus, and the representative members of the genera Hepatovirus and Tremovirus. (c) Pairwise comparison of the novel picornavirus with representative members of the genera Hepatovirus and Tremovirus. (d) Genome organization of gapovirus
