Figure 1

Phylogenetic trees and schematic representation of the dicistrovirid genomes (a. structural polyprotein; b. non-structural polyprotein). Trees were inferred using the neighbor joining method [30] and rooted by the mid-point rooting method [31]. Numbers above and below the branches are bootstrap values (1000 replications) and branch lengths (amino-acid substitutions per site), respectively. Phylogenetic analyses were conducted with MEGA [28]. The approximate locations and sizes of the known genes (blue), overlapping hypothetical genes (red, green, and orange), and singlet ORFs (gray) are noted in the three reading frames.
