FIG. 1.

(A) Structural arrangement of the ASFV UK gene region in pathogenic virus isolates E70, Malawi Lil-20/1 (Mal Lil-20/1), and Haiti 811 (HT). H-1, ORF MR region; H-2, ORF NL carboxyl terminus region; U, unique region; H-3, MGF363/360 ORF OR region; LVR, left variable region; CVR, central variable region; RVR, right variable region. (B) Alignment of the predicted amino acid sequences encoded by the UK genes in the E70 and HT viruses. Identical residues are shown as uppercase boldface letters, while conservative amino acid substitutions are indicated by uppercase lightface letters. Periods denote missing amino acids.
