Mitigating the Effects of Grapevine Red Blotch Virus Using Crop Thinning and Investigating the Role of Viral Load on Vine Health and Fruit Composition in Cabernet Sauvignon in the Okanagan Valley, British Columbia

open access: yesAustralian Journal of Grape and Wine Research, Volume 2025, Issue 1, 2025.
Grapevine red blotch virus (GRBV) is an important threat to vineyards in North America due to severe impacts to vine health, fruit composition, and wine quality. The goal of this study was to investigate the utility of crop thinning to mitigate the effects of GRBV in Cabernet Sauvignon in the Okanagan Valley and to determine if GRBV viral load plays a ...

p24G1 Encoded by Grapevine Leafroll-Associated Virus 1 Suppresses RNA Silencing and Elicits Hypersensitive Response-Like Necrosis in Nicotiana Species

open access: yesViruses, 2020
Grapevine leafroll-associated virus 1 (GLRaV-1) is a major pathogen associated with grapevine leafroll disease. However, the molecular mechanisms underlying GLRaV-1 interactions with plant cells are unclear.

Transmission of Grapevine leafroll-associated virus-1 (Ampelovirus) and Grapevine virus A (Vitivirus) by the Cottony Grape Scale, Pulvinaria vitis (Hemiptera: Coccidae)

open access: yesViruses, 2021
The cottony grape scale Pulvinaria vitis is a scale insect colonizing grapevine; however, its capacity as a vector of grapevine viruses is poorly known in comparison to other scale species that are vectors of viral species in the genera Ampelovirus and ...

Inter‐virus relationships in mixed infections and virus‐drought relationships in plants: a quantitative review

open access: yesThe Plant Journal, Volume 117, Issue 6, Page 1786-1799, March 2024.
SUMMARY Inter‐virus relationships in mixed infections and virus‐drought relationships are important in agriculture and natural vegetation. In this quantitative review, we sampled published factorial experiments to probe for relationships against the null hypothesis of additivity.

Sanitary status of the Grapevine germplasm collection in Republic of Srpska [PDF]

open access: yesAgroznanje, 2016
In July 2015, 179 grapevine plants belonging to 16 grapevine autochthonous cultivars were assessed for sanitary status using DAS ELISA test for the presence of: Grapevine fanleaf virus (GFLV), Grapevine leafroll-associated virus 1 (GLRaV-1), Grapevine ...

The nanovirus U2 protein suppresses RNA silencing via three conserved cysteine residues

open access: yesMolecular Plant Pathology, Volume 25, Issue 1, January 2024.
The nanovirus U2 protein was identified as the suppressor of RNA silencing. Three cysteine residues were critical to its nuclear localization, self‐interaction and siRNA‐binding ability, and were essential for its VSR activity. Abstract Nanoviruses have multipartite, circular, single‐stranded DNA genomes and cause huge production losses in legumes and ...

Detection of Grapevine Leafroll-Associated Virus 1 and 3 in White and Red Grapevine Cultivars Using Hyperspectral Imaging

open access: yesRemote Sensing, 2020
Grapevine leafroll disease (GLD) is considered one of the most widespread grapevine virus diseases, causing severe economic losses worldwide. To date, six grapevine leafroll-associated viruses (GLRaVs) are known as causal agents of the disease, of which ...
