A barnavirus sequence mined from a transcriptome of the Antarctic pearlwort Colobanthus quitensis
(2018-03)Because so few viruses in the family Barnaviridae have been reported, we searched for more of them in public sequence databases. Here, we report the complete coding sequence of Colobanthus quitensis associated barnavirus ... -
A fijivirus major viroplasm protein shows RNA-stimulated ATPase activity by adopting pentameric and hexameric assemblies of dimers
(American Society for Microbiology, 2023-02)Fijiviruses replicate and package their genomes within viroplasms in a pro cess involving RNA-RNA and RNA-protein interactions. Here, we demonstrate that the 24 C-terminal residues (C-arm) of the P9-1 major viroplasm protein ... -

Advances in characterization and epidemiology of strawberry viruses and phytoplasmas in Argentina
(2017-04)The presence of systemic pathogens, such as viruses and phytoplasmas, in strawberry plants is the usual situation worldwide. More than 20 virus species and 6 phytoplasmas 16Sr groups have been cited infecting strawberries ... -
Advances in the etiology of sweet potato (Ipomoea batatas (L.) Lam) yellow curling disease in Argentina
(Facultad de Ciencias Agrarias, Universidad Nacional de Cuyo, 2022-12)Sweet potato yellow curling (YC), the most severe disease of sweet potato detected in Argentina, causes symptoms and damage to sweet potato crops in all cultivated regions. Since 2010/11, the presence of four viruses has ... -
Aggressiveness of Cuban Papaya ringspot virus Isolates on Carica papaya L. cv. Maradol Roja under Greenhouse Conditions
(SciTechnol, 2017-04-16)Carica papaya is a major fruit crop in tropical and subtropical regions; however, its production has several constraints. Papaya ringspot virus (PRSV) is the most important pathogen affecting papaya plantations. Symptoms ... -
Agroinoculation of a full-length cDNA clone of cotton leafroll dwarf virus (CLRDV) results in systemic infection in cotton and the model plant Nicotiana benthamiana
(2013-07)Cotton blue disease is the most important viral disease of cotton in the southern part of South America. Its etiological agent, cotton leafroll dwarf virus (CLRDV), is specifically transmitted to host plants by the aphid ... -
Alfalfa dwarf cytorhabdovirus P protein is a local and systemic RNA silencing supressor which inhibis program med RISC activity and prevents transitive amplification of RNA silencing
(2016)Plants employ RNA silencing as an innate defense mechanism against viruses. As a counter-defense, plant viruses have evolved to express RNA silencing suppressor proteins (RSS), which target one or more steps of the ... -
Amenazas asociadas a virus emergentes que infectan papaya en Argentina
(Centro Nacional de Sanidad Agropecuaria (CENSA), Cuba, 2023-05-08)La papaya (Carica papaya) se establece como una alternativa sustentable en el norte de Argentina, donde su producción se ha incrementado significativamente en los últimos años. Considerando el elevado número de virus que ... -
Amesuviridae: a new family of plant-infecting viruses in the phylum Cressdnaviricota, realm Monodnaviria
(Springer, 2023-08-10)The phylum Cressdnaviricota comprises viruses with single-stranded, circular DNA genomes that encode an HUH-type endonuclease (known as Rep). The phylum includes two classes, eight orders, and 11 families. Here, we report ... -
Analysis of the coding-complete genomic sequence of groundnut ringspot virus suggests a common ancestor with tomato chlorotic spot virus
(2016)Groundnut ringspot virus (GRSV) and tomato chlorotic spot virus (TCSV) share biological and serological properties, so their identification is carried out by molecular methods. Their genomes consist of three segmented RNAs: ... -
