Phylogenetic analysis of isolates PO1, PL3, and CV2 and other viruses from the family Luteoviridae . (A) The predicted amino acid sequences of the CP and (B) the C-terminal region of RdRp were aligned with Multalign and the trees were constructed with MEGA4. Bootstrap values are indicated at each node of the trees. GeneBank accession numbers for the sequences are listed in the Materials and Methods section. Luteovirus, Polerovirus, and Enamovirus members are distinguished with grey, orange, and blue circles, respectively. Carrot red leaf virus (CRLV) and Tobacco vein distorting virus (TVDV) are unclassificated Luteoviridae members with Polerovirus-like RdRps.
