Evolutionary relationships among members of the Bromoviridae deduced from whole proteome analysis.
Many molecular phylogenies of viruses build upon the analysis of single genes. The study of whole-genomes, however, might yield more reliable information to infer tree topologies and a better approach for drawing the evolutionary history of virus families. In this study, we apply a novel comparative proteomic approach to seek whether incorporating information from the entire proteome would support the actual taxonomy of the family Bromoviridae. Our results suggest that the current taxonomic classification should be modified in several aspects to account for the genomic properties of the Bromoviridae. These differences are: i) Alfalfa mosaic virus (AMV) is a true Ilarvirus instead of constituting an independent genus; ii) Pelargonium zonate spot virus (PZSV) should be considered as a member of the Bromoviridae; and iii) the genus Ilarvirus should be divided into fewer phylogenetic subgroups than suggested by antigenic differences.
