Multiple alignments on the B2L genes and on the F1L genes. (A) Twenty-four B2L gene sequences from the world were used in multiple comparisons and their aa identity was displayed in (A). Black triangles represent five important isolates published previously. Blue boxes represent the isolates which this study investigated. Red boxes represent the maximum among these subjects. (B) Fourteen F1L gene sequences from China together with NZ2, IA82, SA00, and B029, were used in multiple alignment and the obvious difference was showed at the proline rich regions of N-terminal. Other motifs were essentially conservative (31). One black pentastar indicates the orf virus isolate of previous; Two-black-pentastar indicates the orf virus isolate in this paper.
