Fig. 2.

Recombination analysis using SimPlot. (A) all FG sequences from OB-Shrops (grey trace), OB-Hants (grey trace) and OB-Warks (black trace) queried against O₁/Campos/BRA/58 (AY593819). (B) all previous FG sequences analysed (gray traces) plus that of A₂₆/Argentina/66 (AY593770) (black trace) queried against the FG sequence of the OB-Warks sample. Analysis performed using a sliding window size of 200 nt moving in steps of 20 nt along the alignment. The pairwise similarity values were plotted at the midpoint of the 200 nt window. At the top of the figure, a fully annotated FMDV FG sequence is represented.
