(A) Genomic organizations of porcine circovirus-like viruses. The locations of putative Rep genes and other ORFs (encoding proteins greater than 100 amino acids long) are indicated by arrows. The stem-loop is also shown. (B) Maximum-likelihood phylogenetic analysis of the Reps of novel porcine circovirus-like viruses and Reps from small circular ssDNA genomes or integrated in Entamoeba histolytica. Circovirus-like genomes are from various environmental sources.
