The characteristics of repeat sequences in coding regions. A The ratio of amino acids in repeat protein sequences versus nonrepeat protein sequences in ASFV strains. B The ratio of secondary structures in repeat protein sequences versus nonrepeat protein sequences. C The ratio of amino acids exposed in repeat protein sequences versus nonrepeat protein sequences. An exposed amino acid was defined as a residue with a relative solvent accessible surface area (rASA) greater than 0.25. D–F The ratio of disordered, penetrating peptides and antimicrobial peptides in repeat protein sequences versus nonrepeat protein sequences. For subfigures B to D, only nonredundant protein sequences were used. “*”, p value < 0.05; “**”, p value < 0.01.
