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 ...

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.

Nanobody-mediated resistance to Grapevine fanleaf virus in plants. [PDF]

Plant Biotechnol J, 2018
SummarySince their discovery, single‐domain antigen‐binding fragments of camelid‐derived heavy‐chain‐only antibodies, also known as nanobodies (Nbs), have proven to be of outstanding interest as therapeutics against human diseases and pathogens including viruses, but their use against phytopathogens remains limited.

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).

Profiling Plant Proteome and Transcriptome Changes during Grapevine Fanleaf Virus Infection. [PDF]

J Proteome Res, 2023
Viruses can elicit varying types and severities of symptoms during plant host infection. We investigated changes in the proteome and transcriptome of Nicotiana benthamiana plants infected by grapevine fanleaf virus (GFLV) with an emphasis on vein clearing symptom development. Comparative, time-course liquid chromatography tandem mass spectrometry and 3'

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 ...

Structural basis of nanobody recognition of grapevine fanleaf virus and of virus resistance loss. [PDF]

Proc Natl Acad Sci U S A, 2020
AbstractGrapevine fanleaf virus (GFLV) is a picorna-like plant virus transmitted by nematodes that affects vineyards worldwide. Nanobody (Nb)-mediated resistance against GFLV has been created recently and shown to be highly effective in plants including grapevine, but the underlying mechanism is unknown.

Structural insights into viral determinants of nematode mediated Grapevine fanleaf virus transmission. [PDF]

PLoS Pathog, 2011
Many animal and plant viruses rely on vectors for their transmission from host to host. Grapevine fanleaf virus (GFLV), a picorna-like virus from plants, is transmitted specifically by the ectoparasitic nematode Xiphinema index. The icosahedral capsid of GFLV, which consists of 60 identical coat protein subunits (CP), carries the determinants of this ...
