Phylogenetic trees reconstructed using the amino acid sequences for (A) the P1-P2 fusion protein and (B) the P3-P5 read-through protein of representative members of the family <i>Luteoviridae</i>.

<p>Trees were constructed by the neighbor-joining method and the statistical significance of branches was evaluated by bootstrap analysis (1,000 replicates). Only bootstrap values above 70% are indicated. The scale bars represent 10% (A) or 5% (B) amino acid divergence. BYDV-Ker-III K460, BYDV-Ker-II K465 and BYDV-Ker-II K439 are indicated in bold italics. The genera to which the particular viruses belong are indicated on the right. The abbreviations followed by the accession numbers are: RSDaV, <i>Rose spring dwarf-associated virus</i>; BLRV, <i>Bean leafroll virus</i>; SbDV, <i>Soybean dwarf virus</i>; PEMV, <i>Pea enation virus</i>; PLRV, <i>Potato leafroll virus</i>; BChV, <i>Beet chlorosis virus</i>.
