Phylogeny of the viral isolates. (A) Phylogenetic trees were constructed based on nucleotide sequence alignments of the CLRDV CP coding region, 606 nt, or (B) on the partial RdRp coding region, 280 nt. Numbers above the lines indicate the bootstrap scores out of 1,000 replicates. The tree was constructed with MEGA4 and the scale bar represents genetic distance. The TYV sequence used was deposited in the GenBank database under the accession number X13063.
