FIG. 2.

Recombinant regions detected within BFDV sequences. Region coordinates are nucleotide positions relative to the origin of virion strand replication. Rep, Rep gene; CP, CP gene; V2, second virion sense ORF. Wherever possible, the origin of the recombinant region is identified. Whenever the origin of a particular recombinant region is identified, the isolate named is a close relative of the parental virus of that region. Recombinant regions and parental viruses were identified by using the RDP (R), Geneconv (G), bootscanning (B), and MaxChi (M) methods. Uppercase letters indicate that a region was identified by a method with greater than 99% certainty (99% bootstrap support in the case of bootscanning). Lowercase letters indicate that a region was identified by a method with between 95 and 99% certainty (between 95 and 99% bootstrap support in the case of bootscanning).
