A strain of Bacillus subtilis subsp. subtilis shows a specific antagonistic activity against the soil-borne pathogen of onion Setophoma terrestris
(2015)Pink Root is among the major diseases of onion and its causal agent, Setophoma terrestris, is one of the most severe pathogens in soils of tropical and subtropical climates. The management of Pink Root is difficult and the ... -
First report of papaya ringspot virus w infecting momordica charantia in Cuba
(Dipartimento di Scienze del Suolo, della Pianta e degli Alimenti, Università di Bari, 2015-01-16)During a survey conducted in July 2010, severe mosaic and deformations were observed on the leaves of cerasee (Momordica charantia) in Villa Clara, Cuba. The symptoms resembled those induced by Papaya ringspot virus (PRSV) ... -
Tomato mottle wrinkle virus, a recombinant begomovirus infecting tomato in Argentina
(Springer, 2015-02)Begomoviruses seriously threaten tomato production in South America. Here, we present the molecular characterization of a novel tomato-infecting begomovirus isolated in Argentina and demonstrate its infectivity. After ... -
Estado actual de la sanidad del cultivo de maíz en Argentina
(Asociación Argentina de Productores en Siembra Directa, 2015-02-06)En el país, un factor relevante para la difusión de las enfermedades en el maíz lo constituye el desarrollo y adopción de nuevos escenarios tecnológicos productivos con la incorporación masiva de sistemas de labranza que ... -
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 ... -
Detection and identification of a novel 16SrXIII subgroup phytoplasma associated with strawberry red leaf disease in Argentina
(2015-08)Strawberry red leaf phytoplasma was found in strawberry plants from production fields in Lules (Tucumán province) and Bella Vista (Corrientes province), Argentina. Characteristic strawberry red leaf symptoms were stunting, ... -
Complete genome sequence and integrated protein localization and interaction map for alfalfa dwarf virus, which combines properties of both cytoplasmic and nuclear plant rhabdoviruses
(Elsevier, 2015-09)We have determined the full-length 14,491-nucleotide genome sequence of a new plant rhabdovirus, alfalfa dwarf virus (ADV). Seven open reading frames (ORFs) were identified in the antigenomic orientation of the negative-sense, ... -
Use of silencing reporter and agroinfiltration transient assays to evaluate the potential of hpRNA construct to induce multiple tospovirus resistance
(2015-12)Tospoviruses are devastating plant viruses causing severe economic losses in a diverse range of crops worldwide. Here, we describe the development and evaluation of an RNA interference (RNAi) broad-spectrum virus resistance ... -
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 ... -
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 ... -
FISH-mapping of the 5S rDNA locus in chili peppers (Capsicum-Solanaceae)
(2016)We present here the physical mapping of the 5S rDNA locus in six wild and fi ve cultivated taxa of Capsicum by means of a genus-specifi c FISH probe. In all taxa, a single 5S locus per haploid genome that persistently mapped ... -
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 ... -
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, ... -
