Análisis molecular de la interacción entre el Mal de Río Cuarto virus (MRCV) y sus hospedantes alternativos : plantas e insectos
De Haro, Luis Alejandro (Facultad de Ciencias Exactas y Naturales, Universidad de Buenos Aires, 2017-03)El virus del Mal de Río Cuarto (MRCV) causa la principal enfermedad del maíz en nuestro país y es transmitido de manera persistente y propagativa por delfácidos. Diversas evidencias indican que los virus de este género se ... -
Complete genome sequence of maize yellow striate virus, a new cytorhabdovirus infecting maize and wheat crops in Argentina
Maurino, Maria Fernanda; Dumon, Analia Delina; Llauger, Gabriela; Alemandri, Vanina Maria; De Haro, Luis Alejandro; Mattio, Maria Fernanda; Del Vas, Mariana; Laguna, Irma Graciela; Gimenez Pecci, Maria De La Paz (Springer, 2018-01)A rhabdovirus infecting maize and wheat crops in Argentina was molecularly characterized. Through next-generation sequencing (NGS) of symptomatic leaf samples, the complete genome was obtained of two isolates of maize ... -
Crop metabolomics : from diagnostics to assisted breeding
Alseekh, Saleh; Bermudez Salazar, Luisa; De Haro, Luis Alejandro; Fernie, Alisdair R.; Carrari, Fernando (Springer, 2018-11)Background Until recently, plant metabolomics have provided a deep understanding on the metabolic regulation in individual plants as experimental units. The application of these techniques to agricultural systems subjected ... -
Interaction of Mal de Río Cuarto virus (Fijivirus genus) proteins and identification of putative factors determining viroplasm formation and decay
Llauger, Gabriela; De Haro, Luis Alejandro; Alfonso, Victoria; Del Vas, Mariana (2017)Mal de Río Cuarto virus (MRCV) is a member of the Fijivirus genus, within the Reoviridae family, that repli-cates and assembles in cytoplasmic inclusion bodies called viroplasms. In this study, we investigatedinteractions ... -
Mal de Río Cuarto virus infection causes hormone imbalance and sugar accumulation in wheat leaves
De Haro, Luis Alejandro; Arellano, Sofía Maité; Novak, Ondrej; Feil, Regina; Dumon, Analia Delfina; Mattio, Maria Fernanda; Tarkowska, Danuse; Llauger, Gabriela; Strnad, Miroslav; Lunn, John Edward; Pearce, Stephen; Figueroa, Carlos María; Del Vas, Mariana (BMC, 2019-03)Background; Mal de Río Cuarto virus (MRCV) infects several monocotyledonous species including maize and wheat. Infected plants show shortened internodes, partial sterility, increased tillering and reduced root length. To ... -
Mal de Río Cuarto Virus infection triggers the production of distinctive viral-derived siRNA profiles in wheat and Its planthopper vector
De Haro, Luis Alejandro; Dumon, Analia Delina; Mattio, Maria Fernanda; Arguello Caro, Evangelina Beatriz; Llauger, Gabriela; Zavallo, Diego; Blanc, Hervé; Mongelli, Vanesa Claudia; Truol, Graciela Ana Maria; Saleh, María-Carla; Asurmendi, Sebastian; Del Vas, Mariana (2017)Plant reoviruses are able to multiply in gramineae plants and delphacid vectors encountering different defense strategies with unique features. This study aims to comparatively assess alterations of small RNA (sRNA) ... -
Mapping causal mutations by exome sequencing in a wheat TILLING population: a tall mutant case study
Mo, Youngjun; Howell, Tyson; Vasquez Gross, Hans; De Haro, Luis Alejandro; Dubcovsky, Jorge; Pearce, Stephen (Springer, 2018-04)Forward genetic screens of induced mutant plant populations are powerful tools to identify genes underlying phenotypes of interest. Using traditional techniques, mapping causative mutations from forward screens is a lengthy, ... -
Population genetics structure of glyphosate‐resistant Johnsongrass (Sorghum halepense L. Pers) does not support a single origin of the resistance
Fernandez, Luis German; De Haro, Luis Alejandro; Distefano, Ana Julia; Martinez, Maria Carolina; Lia, Veronica Viviana; Papa, Juan Carlos; Olea, Ignacio; Tosto, Daniela Sandra; Hopp, Horacio Esteban (Wiley, 2013-09)Single sequence repeats (SSR) developed for Sorghum bicolor were used to characterize the genetic distance of 46 different Sorghum halepense (Johnsongrass) accessions from Argentina some of which have evolved toward ...
