Detection of ERV-DC proviruses in domestic cat and wildcat genomes. (A) A phylogenetic tree of the ERV-DC 3′ LTR was constructed using maximum likelihood methods. The percentages at the branch junctions indicate bootstrap values (1,000 replicates). Thirteen ERV-DC loci were classified into three genotypes: genotype I (ERV-DC1, -DC2, -DC3, -DC4, -DC8, -DC14, -DC17, and -DC19), genotype II (ERV-DC7 and -DC16), and genotype III (ERV-DC6, -DC10, and -DC18). (B to D) Insertional polymorphisms of 13 ERV-DCs in Japanese domestic cats (B), European wildcats (C), and European domestic cats (D). Green and +, provirus detected; red and +/−, heterozygous (the copy is present on one of two chromosomes); blue and +/+, homozygous (the copy is present on both chromosomes). (E) Comparison of genotype frequencies for three loci (ERV-DC14, -DC16, and -DC7) among different cat populations. (F) PCR detection of ERV-DC genotypes in European wildcats (F. s. silvestris). Statistical analyses were conducted using Student’s t tests and one-way ANOVAs. *, P < 0.0001.
