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 ... -
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 ... -
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: ... -
Use of 454-Pyrosequencing for the characterization of Sweet potato virus C and Sweet Potato Feathery Mottle virus Isolates fron Argentina and Development of a Multiplex one - step RT-PCR for Their Simultaneous Detection
(2016)454-pyrosequencing was applied as a tool to identify etiological agents involved in the symptoms observed in a sweet potato sample from Argentina. RNA was purified from symptomatic material and sequenced using a Roche 454 ... -
Molecular detection of Thecaphora frezzi in peanut (Arachis Hypogaea L.) seeds
(2016)Thecaphora frezii is the causal agent of peanut smut, important disease in the Argentine production area. The pathogen can be dispersed by kernels, through surface contamination or small lesions. The aim of this work was ... -
First report of cowpea mild mottle virus in chia (Salvia hispanica)
(2016)Chia (Salvia hispanica), a herbaceous plant of Lamiaceae family, has gained popularity due to its high concentrations of health-beneficial Omega-3 fatty acids. Plants showing different virus-like symptoms were observed ... -
Genetic variability and recombination analysis of the coat protein gene of Strawberry mild yellow edge virus
(2016)Strawberry mild yellow edge virus (SMYEV) has been detected in most of the strawberry production regions worldwide. However, little is known about differences between distinct isolates. The aim of this study was to enhance ... -
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, ... -
Occurrence and characterization of a severe isolate of Watermelon mosaic virus from Argentina
(2016)More than 50 viruses have been reported in cucurbit crops worldwide. In Argentina, cucurbit viruses have been associated with important yield losses. The most prevalent and widespread potyvirus is Watermelon mosaic virus ... -
Development of a non-radioactive molecular hybridization probe for detecting Strawberry mottle virus in strawberry
(2016)The vegetative propagation of strawberries favors transmission of systemic pathogens, such as viruses, which are one of the main yield-limiting factors for this crop. More than 20 viruses have been described as infecting ... -
Incidence of Garlic common latent virus in Argentina, and phylogenetic and recombination analyses of isolates = Incidência de Garlic common latent virus na Argentina, e análise filogenética e de recombinação de isolados
(Embrapa, 2015-05)The objective of this work was to estimate the incidence and prevalence of Garlic common latent virus (GarCLV) in the main production regions of garlic (Allium sativum) in Argentina, and to perform phylogenetic and ... -
First biological data of Ceresa nigripectus [Hemiptera:Membracidae], a common treehopper on alfalfa crops in Argentina
(2014-12)Alfalfa (Medicago sativa L.; Fabaceae) is essential for argentinean agricultural development, but diseases like “witches´ broom», caused by the ArAWB phytoplasma, are limiting factors for the production of this crop. ... -
Exploring the genes of Yerba Mate (Ilex paraguariensis A. St.-Hil.) by NGS and De Novo Transcriptome Assembly
(2014-10-16)Yerba mate (Ilex paraguariensis A. St.-Hil.) is an important subtropical tree crop cultivated on 326,000 ha in Argentina, Brazil and Paraguay, with a total yield production of more than 1,000,000 t. Yerba mate presents a ... -
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 ... -
Essential oils and their combinations with iprodione fungicide as potential antifungal agents against withe rot (Sclerotium cepivorum Berk) in garlic (Allium sativum L.) crops
(2016)This study was conducted to evaluate essential oils (EOs) and their binary combinations with fungicideiprodione (Ip) as a potential fungicide against Sclerotium cepivorum Berk in order to reduce the amountof pesticide ...
