Despite the rapid mutational change that is typical of positive-strand RNA viruses, enzymes
mediating the replication and expression of virus genomes contain arrays of conserved …

Grapevine fanleaf virus (GFLV) is responsible for fan-leaf degeneration, which is one of the
most severe virus diseases of grapevines worldwide. GFLV causes substantial crop losses …

A systematic bioinformatic approach to identifying the evolutionarily conserved regions of
proteins has verified the universality of a newly described conserved motif in RNA …

Many viruses express their genome, or part of their genome, initially as a polyprotein
precursor that undergoes proteolytic processing. Molecular genetic analyses of viral gene …

Similarities in genome organization and replication strategy permit viruses to be organized
into 'super-groups'–often including both animal and plant viruses. This article is the first in a …

The viral determinants involved in the specific transmission of Grapevine fanleaf virus
(GFLV) by its nematode vector Xiphinema index are located within the 513 C-terminal …

RNA extracted from 120 leaf specimens from 17 plant species was pooled, and
polyadenylated RNA species were sequenced together without barcoding in one lane using …

Plant-infecting viruses of the genus Nepovirus (subfamily Comovirinae, family Secoviridae,
order Picornavirales) are bipartite positive-strand RNA viruses with each genomic RNA …

A virus with isometric virus particles (ca. 25 nm) was isolated from an apple tree and named
Apple latent spherical virus (ALSV). Virus particles purified from infected Chenopodium …

ABSTRACT A serious disease was observed in black raspberry (Rubus occidentalis) in
Oregon in the last decade. Plants showing mosaic symptoms declined rapidly and, in many …
