Bootscan plots showing the likehood of recombinant sequence (Asia1/WHN/CHA/06) with JS/CHA/05 and HNK/CHA/05. The y-axis indicates the percentage of bootstrap values that support the clustering of Asia1/WHN/CHA/06 with the parental strains. Boot strap values over 70% are considered significant. The area outlined in pink demarcates the potential recombination regions. Crossover sites were indicated by arrows with nt positions above.
