Metagenomic identification of novel viruses of maize and teosinte in North America

BMC Genomics, 2022
Background Maize-infecting viruses are known to inflict significant agronomic yield loss throughout the world annually. Identification of known or novel causal agents of disease prior to outbreak is imperative to preserve food security via future crop ...

Autophagy Inhibits Intercellular Transport of Citrus Leaf Blotch Virus by Targeting Viral Movement Protein

Viruses, 2021
Autophagy is an evolutionarily conserved cellular-degradation mechanism implicated in antiviral defense in plants. Studies have shown that autophagy suppresses virus accumulation in cells; however, it has not been reported to specifically inhibit viral ...

Evolutionary Analysis of Grapevine Virus A: Insights into the Dispersion in Sicily (Italy)

Agriculture, 2022
Grapevine virus A (GVA) is a phloem-restricted virus (genus Vitivirus, family Betaflexiviridae) that cause crop losses of 5–22% in grapevine cultivars, transmitted by different species of pseudococcid mealybugs, the mealybug Heliococcus bohemicus, and by

The genetic variability of grapevine Pinot gris virus (GPGV) in Australia

Virology Journal, 2023
Grapevine Pinot gris virus (GPGV; genus Trichovirus in the family Betaflexiviridae) was detected in Australia in 2016, but its impact on the production of nursery material and fruit in Australia is still currently unknown.

Characterizing the Virome of Apple Orchards Affected by Rapid Decline in the Okanagan and Similkameen Valleys of British Columbia (Canada)

Pathogens, 2022
Rapid apple decline disease (RAD) has been affecting orchards in the USA and Canada. Although the primary cause for RAD remains unknown, viruses may contribute to the incidence or severity of the disease.

Discovery of novel tepovirus genomes with a nucleic acid-binding protein homolog by systematic analysis of plant transcriptome data

Acta Virologica
Some plant RNA viruses in the family Betaflexiviridae encode a nucleic acid-binding protein (NABP) that facilitates infection by suppressing the host RNA silencing response.

Structure and Genome Organization of Cherry Virus A ( Capillovirus, Betaflexiviridae ) from China Using Small RNA Sequencing [PDF]

Genome Announcements, 2016
ABSTRACT Cherry virus A (CVA) ( Capillovirus, Betaflexiviridae ) is widely present in cherry-growing areas. We obtained the complete genome of a CVA isolate (CVA-TA) using small RNA deep sequencing, followed by overlapping reverse transcription-PCR (RT-PCR) and rapid amplification of cDNA ends (

Characterization of three new viruses of the family Betaflexiviridae associated with camellia ringspot disease

Virus Research, 2019
Foliar chlorotic and necrotic ringspots of different sizes were observed in many ornamental camellia (Camellia spp.) species and cultivars with or without variegation symptoms. In this study, flexuous, filamentous virions of approximately 680-780 nm long were observed by electron microscopy in sap of camellia trees with chlorotic ringspots.
