  • Title: The sequence of RNA 1 and RNA 2 of tobacco streak virus: additional evidence for the inclusion of alfalfa mosaic virus in the genus Ilarvirus.
    Author: Scott SW, Zimmerman MT, Ge X.
    Journal: Arch Virol; 1998; 143(6):1187-98. PubMed ID: 9687875.
    Abstract:
    Here we describe the complete sequence of RNA 1 and 2 of the WC isolate of tobacco streak virus (TSV). These two sequences complete the information on the genome of TSV, the type member of the genus Ilarvirus, and are the first sequences described for the RNA 1 and RNA 2 of a member of subgroup 1 of this genus. The sequences have a similar organization to those reported for the corresponding RNAs of other ilarviruses. However, the putative translation products of these two molecules differ sufficiently from previously sequenced ilarviruses so that TSV should remain in a subgroup on its own. Phylogenetic comparison of sequence data for RNA 1 with that of other ilarviruses and alfalfa mosaic virus (AMV) reveals two distinct clusters (TSV, CiLRV, and SpLV) and (AMV, PDV, and ApMV). These data support the suggestion [16] based on data for RNA 3 of ilarviruses that AMV should be included as a true ilarvirus.
