Epidemiología del tomato spotted wilt virus en el contexto de la virosis de papa en el sudeste bonaerense y Argentina.
Salvalaggio, Andrea Eugenia (Facultad de Ciencias Agrarias, Universidad Nacional de Mar del Plata, 2021-10)El Sudeste Bonaerense es la principal región productora de papa para consumo, industria y semilla en Argentina. Las virosis afectan el rendimiento y la calidad de los tubérculos de la papa. La transmisión de los virus es ... -
Pautas para el manejo de “Top necrosis” en el cultivo de papa
Salvalaggio, Andrea Eugenia; Lopez Lambertini, Paola Maria; Cendoya, Maria Gabrie; Huarte, Marcelo Atilio (Estación Experimental Agropecuaria Balcarce, INTA, 2017)La prevención de la top necrosis en el cultivo incluye la producción de semilla libre del virus, la eliminación de plantas infectadas en etapas tempranas y el monitoreo y control de Frankiniella occidentalis en la etapa ... -
Reaction of South American wheat genotypes to wheat streak mosaic virus
Alemandri, Vanina Maria; Bainotti, Carlos Tomas; Lau, Douglas; Navia, Denise; Rodriguez, Sandra Monica; Lopez Lambertini, Paola Maria; Truol, Graciela Ana Maria (Springer, 2018-08)Wheat streak mosaic virus (WSMV) is an emerging virus in South America that threatens cereal production. Genetic resistance is used in other regions as an effective strategy for management of this disease. The susceptibility ... -
Reconstruction and characterization of full-length begomovirus and alphasatellite genomes infecting pepper through metagenomics
Bornancini, Veronica Andrea; Irazoqui, Jose Matias; Flores, Ceferino Rene; Vaghi Medina, Carlos Gaston; Amadio, Ariel; Lopez Lambertini, Paola Maria (MDPI, 2020-02)In northwestern Argentina (NWA), pepper crops are threatened by the emergence of begomoviruses due to the spread of its vector, Bemisia tabaci (Gennadius). The genus Begomovirus includes pathogens that can have a monopartite ... -
Situación de las virosis del cultivo de papa en el Sudeste Bonaerense
Salvalaggio, Andrea Eugenia; Bruno, Cecilia Inés; Huarte, Marcelo Atilio; Lopez Lambertini, Paola Maria (Ediciones INTA, 2022-04)En el sudeste de la provincia de Buenos Aires se encuentra la principal región productora de papa de la Argentina. La papa que se produce tiene tres destinos: el mercado fresco, la industria y la producción de semilla, la ... -
Temporal and spatial dynamics of Tomato spotted wilt virus and its vector in a potato crop in Argentina
Salvalaggio, Andrea Eugenia; Lopez Lambertini, Paola Maria; Cendoya, Maria Gabriela; Huarte, Marcelo Atilio (2017-07)The nature of spatial and temporal dynamics of Tomato spotted wilt virus (TSWV) and its vector in a potato crop cv. Innovator without insecticide application is analysed. Seed tuber was analysed for the presence of TSWV ... -
Tomato apical leaf curl virus: a novel, monopartite geminivirus detected in tomatoes in Argentina
Vaghi Medina, Carlos Gaston; Teppa, Elin; Bornancini, Veronica Andrea; Flores, Ceferino Rene; Marino Buslje, Cristina; Lopez Lambertini, Paola Maria (2018-01)Plant viruses that are members of the Geminiviridae family have circular single-stranded DNA (ssDNA) genome and are responsible for major crop diseases worldwide. We have identified and characterized a novel monopartite ... -
Tomato mottle wrinkle virus, a recombinant begomovirus infecting tomato in Argentina
Vaghi Medina, Carlos Gaston; Martin, Darren P.; Lopez Lambertini, Paola Maria (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 ... -
Tomato spotted wilt virus detection in the potato cultivar Innovator
Salvalaggio, Andrea Eugenia; Bruno, Cecilia Inés; Huarte, Marcelo Atilio; Lopez Lambertini, Paola Maria (Ediciones INTA, 2024-05)Tomato spotted wilt orthotospovirus (TSWV) causes important economic losses in potato production. The cultivar Innovator is the most widely used variety for potato industrial processing and the second most extensively grown ... -
Use of silencing reporter and agroinfiltration transient assays to evaluate the potential of hpRNA construct to induce multiple tospovirus resistance
Debat, Humberto Julio; Grabiele, Mauro; Ducasse, Daniel Adrian; Lopez Lambertini, Paola Maria (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 ...
