Viral RNase3 Co-Localizes and Interacts with the Antiviral Defense Protein SGS3 in Plant Cells. [PDF]

PLoS ONE, 2016
Sweet potato chlorotic stunt virus (SPCSV; family Closteroviridae) encodes a Class 1 RNase III endoribonuclease (RNase3) that suppresses post-transcriptional RNA interference (RNAi) and eliminates antiviral defense in sweetpotato plants (Ipomoea batatas).

Meta‐analysis reveals strong evidence for adaptive host and vector manipulation by plant viruses

Functional Ecology, Volume 39, Issue 12, Page 3628-3645, December 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Plant viruses often enhance their own transmission by modifying host phenotypes and vector behaviour, leading to the hypothesis that such effects are manipulations due to virus adaptations.

A Closterovirus (Family: Closteroviridae) Isolated from Tobacco Crops in Northern Greece (Macedonia)

Plant Disease, 1999
In 1997, viruslike symptoms similar to those caused by potato potyvirus Y (PVY) were observed in tobacco (Nicotiana tabacum ) plants of the cv. Basmas in the area of Drama (Macedonia) in northern Greece. Diseased plants showed vein clearing and necrosis of the petioles and main veins, and were severely stunted.

Ecology and management of grapevine leafroll disease

Frontiers in Microbiology, 2013
Grapevine leafroll disease (GLD) is caused by a complex of vector-borne virus species in the family Closteroviridae. GLD is present in all grape-growing regions of the world, primarily affecting wine grape varieties. The disease has emerged in the last

Climate Change Drives the Distribution of Insect Vectors for GLRaV‐3 on a Global Scale

Ecology and Evolution, Volume 15, Issue 10, October 2025.
The distribution range of seven insect vectors of GLRaV‐3 were predicted by MaxEnt model. Thermal conditions were a vital factor constraining the potential distribution ranges of all vector insects. Centroid shifts suggested that the potential distribution range of soft scale will move northward under climate change. Our study provides implications for

Genomic and biological analysis of Grapevine leafroll-associated virus 7 reveals a possible new genus within the family Closteroviridae [PDF]

Virus Research, 2012
Deep sequencing analysis of an asymptomatic grapevine revealed a virome containing five RNA viruses and a viroid. Of these, Grapevine leafroll-associated virus 7 (GLRaV-7), an unassigned closterovirus, was by far the most prominently represented sequence in the analysis.

Areca palm velarivirus 1 encoded P25 hijacks host eIF4E and enhances viral translation through strengthening the interaction of eIF4E with 3′ cap-independent translation enhancer

Phytopathology Research
Plant viruses employ diverse strategies to hijack host machinery for viral translation initiation. Cap-independent translation enhancers located in the 3′ untranslated region (3′-CITEs) have been identified in many members of the families Tombusviridae ...

The Heterologous Expression of the p22 RNA Silencing Suppressor of the Crinivirus Tomato Chlorosis Virus from Tobacco Rattle Virus and Potato Virus X Enhances Disease Severity but Does Not Complement Suppressor-Defective Mutant Viruses

Viruses, 2017
To counteract host antiviral RNA silencing, plant viruses express suppressor proteins that function as pathogenicity enhancers. The genome of the Tomato chlorosis virus (ToCV) (genus Crinivirus, family Closteroviridae) encodes an RNA silencing suppressor,

Next-Generation Sequencing Combined With Conventional Sanger Sequencing Reveals High Molecular Diversity in Actinidia Virus 1 Populations From Kiwifruit Grown in China

Frontiers in Microbiology, 2020
Kiwifruit (Actinidia spp.) is native to China. Viral disease–like symptoms are common on kiwifruit plants. In this study, six libraries prepared from total RNA of leaf samples from 69 kiwifruit plants were subjected to next-generation sequencing (NGS ...

Tolerance Against Co‐Infection of Two Partitiviruses and Ourmia‐Likevirus Is Common Among Heterobasidion annosum Strains on Artificial Media and in Dead Wood

Forest Pathology, Volume 55, Issue 5, October 2025.
ABSTRACT Some mycoviruses cause hypovirulence in fungi, but the effects often vary among different host strains. Heterobasidion partitiviruses 13‐an1 and 15‐pa1 (HetPV13‐an1 and HetPV15‐pa1) have been associated with strain‐specific and variable hypovirulence of Heterobasidion annosum, but variation in phenotypic effects of HetPV15‐pa1 or the ...
