SPRE-like elements in host genomes. a Numbers of SPRE-like elements in host genomes. Each dot indicates the numbers of SPRE-like elements, and bar plots show the medians. b Numbers of SPRE-like elements in host families of Euarchonta. c The number of SPRE-like elements overlapping with RepeatMasker tracks in the human genome. SPRE-like elements by extending 50-nt sequences in the 5′ direction (SPRE+5) and in the 3′ direction (SPRE+3) are also examined. d The number of RepeatMasker tracks overlapping with SPRE+3 are indicated as bar plots. The “-int” of “_I” in repeat names indicates internal regions of ERVs. e The number of RepeatMasker tracks overlapping with SPRE+5 are indicated as bar plots. f The number of RepeatMasker tracks overlapping with SPRE+3 in the marmoset genome are indicated as bar plots
