FIG 1.

(A) Organization of the genome of ashy storm-petrel-associated gyrovirus VP1 (putative capsid protein; 1,368 nucleotides), VP2 (unknown function; 699 nucleotides), and VP3 (unknown function; 273 nucleotides). (B) Neighbor-joining phylogenetic tree of representative sequences (NCBI RefSeq) of gyroviruses with 1,000 bootstrap replicate branch support and pairwise identity matrix. (C) Maximum likelihood phylogenetic tree of the VP1 amino acid sequences and the pairwise identities of the VP1 protein and VP1 nucleotide sequences of representative gyroviruses. (D) Maximum likelihood phylogenetic tree of the VP2 amino acid sequences and the pairwise identities of the VP2 protein and VP2 nucleotide sequences of representative gyroviruses. The maximum likelihood phylogenetic trees were inferred using PHYML (17) with the WAG+G substitution model, determined as the optimal model using ProtTest (18), and the pairwise identities were inferred using SDT v1.2 (19).
