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 ... -
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 ... -
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 ... -
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: ... -
Bean yellow mosaic virus in soybean from Argentina
(Wiley, 2014-05)An association of Bean yellow mosaic virus (BYMV), (genus Potyvirus), with yellow mosaic leaf symptoms on soybean in Argentina was determined by enzyme-linked immunosorbent assay, a result confirmed by transmission electron ... -
Biological, Molecular and Phiysiological Characterization of Four Soybean mosaic virus Isolates Present in Argentine Soybean Crops
(BioRxiv, 2021-06-10)Soybean mosaic virus (SMV) causes systemic infections in soybean plants, leading to chlorotic mosaic and producing significant yield losses. The virus is widely distributed in all soybean production areas in the world. In ... -
The complete genome of a putative endornavirus identified in yerba mate (Ilex paraguariensis St. Hil.)
(2014-10)We present the first report of a virus infecting the subtropical tree crop yerba mate (Ilex paraguariensis St. Hil.). Total RNA purification, followed by next-generation sequencing, transcripts assembly and annotation, ... -
Complete genome sequence of a new enamovirus from Argentina infecting alfalfa plants showing dwarfism symptoms
(2016)Alfalfa dwarf disease, probably caused by synergistic interactions of mixed virus infections, is a major and emergent disease that threatens alfalfa production in Argentina. Deep sequencing of diseased alfalfa plant samples ... -
Complete genome sequence of sunflower ring blotch virus, a new potyvirus infecting sunflower in Argentina
(Springer, 2017-06)The complete genome sequence of sunflower ring blotch virus (SuRBV), a previously undescribed potyvirus infecting sunflower in Argentina, is reported. The SuRBV genome comprises 9555 nucleotides (nt) and encodes a polyprotein ... -
Comportamiento de diferentes cultivares de trigo a Wheat streak mosaic virus (WSMV) y High Plains virus (HPV) mediante infección artificial con el vector Aceria tosichella Keifer, bajo condiciones de campo
(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2013-04)El trigo (Triticum aestivum L.) es el cereal de invierno de mayor importancia económica en la Argentina. Dado que Wheat Streak Mosaic virus (WSMV) y High Plains virus (HPV) constituyen una de las principales limitantes ... -
Cucumber mosaic virus infecting ‘Cavendish’ banana in Argentina
(Springer, 2018-12)Banana plants (Musa sp.) showing severe mosaic symptoms in leaves were observed in Laguna Naineck, Formosa, Argentina. Electron microscopy observations of leaf dip preparations revealed isometric particles ca. 30 nm in ... -
Cytorhabdovirus P3 genes encode 30K-like cell-to-cell movement proteins
(2016)Plant viruses encode movement proteins (MP) to facilitate cell-to-cell transport through plasmodesmata. In this study, using trans-complementation of a movement-defective turnip vein-clearing tobamovirus (TVCV) replicon, ... -
Detection and Identification of the First Viruses in Chia (Salvia hispanica)
(MDPI, 2014-09)Chia (Salvia hispanica), an herbaceous plant native to Latin America, has become important in the last 20 years due to its beneficial effects on health. Here, we present the first record and identification of two viruses ... -
Development of a full-length infectious clone of sunflower chlorotic mottle virus (SuCMoV)
