Abstract

Segmented genomes of RNA viruses are thought to evolve and be maintained in analogy to sexual recombination and reassortment in eukaryotic systems. If reassortment among genomes is an important event in cucumoviral evolution, then such events should be detectable among extant viruses. In this study, phylogenetic analyses of cucumoviruses were performed using aligned amino acid sequences. The results reveal different relationships among species when the three genomic segments are compared, suggesting that reassortment events have given rise to extant forms. In addition, we describe a cucumovirus isolate that is composed of genomic segments from two distinct viral species. These results indicate that reassortment events may provide a mechanism for speciation in cucumoviruses.
