Figure 1

The number, position, and distribution of repeat sequences in the genome. A The number of repeat sequences identified in 86 genomes (per kb). B The phylogenetic tree on the left side was built with MEGA based on the C-terminal sequences (415 bp) of the p72 gene (see Materials and methods), and the genotypes of ASFV isolates are labelled with Greek numerals. The three types of repeat sequences in ASFV genomes are indicated by different colours. The black and red arrows refer to examples of genotype-specific repeat sequences in genotypes II and I, respectively.
