Tomato yellow vein streak virus and Tomato golden vein virus: a reappraisal of the classification status of two South American Begomovirus species based upon genome-wide pairwise identity of multiple isolates.

Abstract excerpt

Tomato yellow vein streak virus (ToYVSV) and tomato golden vein virus (TGVV) are begomoviruses reported infecting tomatoes and other hosts across South America. However, their close phylogenetic relationship has generated uncertainties about their taxonomic status and nomenclature. In fact, genomic DNA-A identity levels of isolates reported with an identical virus name may range from 89-100%. In view of the...
