Detection and diversity of viruses infecting African yam (Dioscorea rotundata) in a collection and F1 progenies in Côte d'Ivoire shed light to plant‐to‐plant viral transmission

Plant Pathology, Volume 70, Issue 6, Page 1486-1495, August 2021., 2021
A survey of leaf symptoms and viral molecular indexation on African yam germplasm and two hybrid populations unveiled a high prevalence of yam viruses in Côte d'Ivoire and provided evidence for their plant‐to‐plant transmission. ​ Abstract Yam (Dioscorea spp.) is a major staple food whose production is hampered by viral diseases.

Developing virus-free grapevine explants by using silver-nanoparticles and its comparison with chemo and thermotherapy-based approaches [PDF]

Journal of Crop Protection, 2023
Grapevine viruses cause significant losses in the yield of grape. This study describes applying silver nanoparticles (AgNPs) to produce virus-free grapevine plants and compares it with chemo and thermotherapy.

Challenges of viticulture adaptation to global change: tackling the issue from the roots

Australian Journal of Grape and Wine Research, Volume 27, Issue 1, Page 8-25, January 2021., 2021
Abstract Viticulture is facing emerging challenges not only because of the effect of climate change on yield and composition of grapes, but also of a social demand for environmental‐friendly agricultural management. Adaptation to these challenges is essential to guarantee the sustainability of viticulture.

Association of Satellite RNA with Grapevine fanleaf virus in its Geographical Origin and Sequence Characteristics

Journal of Agricultural Sciences, 2022
The region between The Caspian Sea and Black Sea has been hypothesized as the origin of grapevine. Likewise, an extensive study on Grapevine fanleaf virus (GFLV) from this region suggests this region as a possible origin of the virus.

Grapevine Fanleaf Virus RNA1-Encoded Proteins 1A and 1BHel Suppress RNA Silencing

Molecular Plant-Microbe Interactions, 2023
Grapevine fanleaf virus (GFLV) (genus Nepovirus, family Secoviridae) causes fanleaf degeneration, one of the most damaging viral diseases of grapevines. Despite substantial advances at deciphering GFLV-host interactions, how this virus overcomes the host

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 ...

Complete Nucleotide Sequence of a South African Isolate of Grapevine Fanleaf Virus and Its Associated Satellite RNA

Viruses, 2013
The complete sequences of RNA1, RNA2 and satellite RNA have been determined for a South African isolate of Grapevine fanleaf virus (GFLV-SACH44). The two RNAs of GFLV-SACH44 are 7,341 nucleotides (nt) and 3,816 nt in length, respectively, and its ...

Sampling for vegetative propagation: A phytosanitary status survey of grapevines collection by One Step RT-PCR method

Plant Varieties Studying and Protection, 2021
Purpose. Grapevines (Vitis spp.) are affected by many viral diseases which cause serious pathological problems. GLRaV-3 is among the most widespread leafroll viruses, while Grapevine Fanleaf Virus (GFLV) is a destructive pathogen which reduces the ...

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

PLoS Pathogens, 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
