Identification of recombination event I and II. (A) BOOTSCAN evidence for the recombination origin on the basis of pairwise distance, modeled with a window size 200, step size 20, and 100 Bootstrap replicates; (B) Neighbor joining tree (2,000 replicates, Kimura 2-parameter distance) constructed using the recombinant region (2021-2618 nt); (C) Neighbor joining tree constructed using the recombinant region (4754-5201 nt); (D) Neighbor joining tree constructed using the non-recombinant regions consisted of the rest of the genome. The green, blue, and red shadow boxes showed the parental isolates and the black boxes showed the daughter isolate.
