The ID45 variant caused no foliar symptoms in Cabernet Sauvignon grapevines in the fall.
VitisVerbatim
e1“The ID45 variant caused no foliar symptoms in 'Cabernet Sauvignon' in the fall, and was demonstrated to have poor reactivity to commercial virus-specific antibodies”
e2“Grapevine leafroll-associated virus-3 (GLRaV-3) is a major constraint on profitable grapevine cultivation”

Other claims from this paper (8)
- Observation In Idaho grapevines, the ID45 variant of GLRaV-3 had at most 80% nucleotide sequence identity to known GLRaV-3 isolates in the HSP70h gene.
- Observation The ID45 variant had poor reactivity to commercial virus-specific antibodies.
- Observation The entire genome sequence of the GLRaV-3-ID45 variant is 18,478 nt long.
- Observation The GLRaV-3-ID45 genome has a typical organization for the genus Ampelovirus (family Closteroviridae).
- Observation The GLRaV-3-ID45 genome shares only 70 to 77% identity with GLRaV-3 genomes from other established phylogroups.
- Observation ID45 represents a new phylogenetic group IX of GLRaV-3.
- Observation The ID45 variant is present in at least one other grape-growing state in the U.S., California, and in Brazil, according to a database search.
- Method / resource An RT-PCR based test distinguishes ID45 from the predominant GLRaV-3 phylogroup I in single and mixed infections.
