Characterization of Grapevine Fanleaf Virus Isolates in ‘Chardonnay’ Vines Exhibiting Severe and Mild Symptoms in Two Vineyards [PDF]

Viruses, 2022
Fanleaf degeneration is a complex viral disease of Vitis spp. that detrimentally impacts fruit yield and reduces the productive lifespan of most vineyards worldwide. In France, its main causal agent is grapevine fanleaf virus (GFLV).

A single resistance factor to solve vineyard degeneration due to grapevine fanleaf virus [PDF]

Communications Biology, 2021
Djennane, Merdinoglu and colleagues identify a single genetic factor, rgflv1, in Riesling grapes that confers a resistance to grapevine fanleaf virus. This resistance factor may inform genetic solutions for control of this virus in many grape varieties.

Phylogenetic Analysis of Grapevine Fanleaf Virus, Grapevine Virus A, and Grapevine Leafroll-Associated Virus 3 in Kazakhstan [PDF]

Microorganisms
Grapevine viruses reduce harvests and degrade fruit quality, but their genetic diversity in Kazakhstan has remained unexplored. We collected symptomatic leaves from local vineyards and recovered eleven fragments of the coat-protein gene: one from ...

High-Throughput Sequencing of Grapevine in Mexico Reveals a High Incidence of Viruses including a New Member of the Genus Enamovirus [PDF]

Viruses, 2023
This is the first viral metagenomic analysis of grapevine conducted in Mexico. During the summer of 2021, 48 plants displaying virus-like symptoms were sampled in Queretaro, an important grapevine-producing area of Mexico, and analyzed for the presence ...

Lettuce Big-Vein Associated Virus ORF3 Encodes a Functional 30K Movement Protein. [PDF]

Mol Plant Pathol
AlphaFold2 + FoldSeek structure guided search predicts the movement protein of lettuce big‐vein associated virus despite low sequence similarity. ABSTRACT Movement proteins (MPs) modulate the size exclusion limit of plasmodesmata—membrane‐lined channels connecting plant cells—thereby allowing cell‐to‐cell movement and systemic spread of plant viruses ...
