(Centro de Ingenieros Agrónomos General Cabrera, 2023-09-21)El cultivo de maní (Arachis hypogaea L.) es afectado por dos enfermedades foliares importantes, la viruela temprana (Cercospora arachidicola) y la viruela tardía (Nothopassalora personata Syn. Cercosporidium personatum). ... -
Citrus psorosis virus 24K protein interacts with citrus miRNA precursors, affects their processing and subsequent miRNA accumulation and target expression
(2016-04)Sweet orange (Citrus sinensis), one of the most important fruit crops worldwide, may suffer from disease symptoms induced by virus infections, thus resulting in dramatic economic losses. Here, we show that the infection ... -
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 ... -
Coupling virus-induced gene silencing to exogenous green fluorescence protein expression provides a highly efficient system for functional genomics in arabidopsis and across all stages of tomato fruit development
(2011-07)Since the advent of the postgenomic era, efforts have focused on the development of rapid strategies for annotating plant genes of unknown function. Given its simplicity and rapidity, virus-induced gene silencing (VIGS) ... -
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, ... -
Detección del potyvirus johnsongrass mosaic virus en Argentina
(Asociación Argentina de Fitopatólogos, 2021-09-22)Los potyvirus son responsables de importantes pérdidas económicas en el cultivo de maíz, uno de los cereales más importante en Argentina. En el norte de la provincia de Córdoba se detectaron plantas con síntomas similares ... -
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)
(Springer; Virology Division, International Union of Microbiological Societies, 2013-02)A full-length cDNA clone (p35SuCMoV) of the sunflower chlorotic mottle virus common strain (SuCMoV-C) genomic RNA was constructed. Three cDNA fragments covering the whole genome of SuCMoV-C were cloned between a cauliflower ... -
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 ... -
Differential mRNA accumulation upon early arabidopsis thaliana infection with ORMV and TMV-Cg Is associated with distinct endogenous small RNAs Level
(2015-08-03)Small RNAs (sRNAs) play important roles in plant development and host-pathogen interactions. Several studies have highlighted the relationship between viral infections, endogenous sRNA accumulation and transcriptional ... -
Distinct strains of the re-emergent Cassava common mosaic virus (genus: Potexvirus) infecting cassava in Argentina
