Recombination and reassortment of viral genomes are major processes contributing to the creation of new, emerging viruses. These processes are especially significant in long-term persistent infections where multiple viral genotypes co-replicate in a single host, generating abundant genotypic variants, some of which may possess novel host-colonizing and pathogenicity traits. In some plants, succ...
Natural Spread of Severe Citrus Tristeza Virus Isolates in Citrus Preinfected with Mild CTV Isolates
During routine graft indexing of Rubus clones at the USDA-ARS Horticultural Crops Research Laboratory in Corvallis, Oregon, a ‘Glen Clova’ plant that originated in Scotland induced severe symptoms including stunting and apical necrosis when grafted on ‘Munger’ black raspberry (Rubus occidentalis). Cloning of viral dsRNA obtained from the plant and sequence analysis indicated the presence of a n...
