Redefining the medicago sativa alphapartitiviruses genome sequences
(Elsevier, 2019-03-29)In Argentina, alfalfa (Medicago sativa L.) is a primary forage crop and a major feed component in dairy and beef cattle production systems. In 2010, we observed alfalfa plants showing symptoms of shortened internodes (bushy ... -
Redox systemic signaling and induced tolerance responses during soybean–bradyrhizobium japonicum interaction: involvement of nod factor receptor and autoregulation of nodulation
(Frontiers Media, 2019-02)The symbiotic relationship between legumes and nitrogen-fixing rhizobia induces local and systemic responses, which ultimately lead to nodule formation. The autoregulation of nodulation (AON) is a systemic mechanism related ... -
Redox-related metabolites and gene expression modulated by sugar in sunflower leaves: similarities with Sunflower chlorotic mottle virus-induced symptom
(Taylor & Francis, 2013)Sugars are part of an integrated redox system, since they are key regulators of respiration and photosynthesis, and therefore of the levels of reducing power, ATP and ROS. These elements are major determinants of the ... -
Reductions in Maize Root-tip Elongation by Salt and Osmotic Stress do not Correlate with Apoplastic O2•− Levels
(Oxford Academic Press, 2008-10)Background and Aims: Experimental evidence in the literature suggests that O2•− produced in the elongation zone of roots and leaves by plasma membrane NADPH oxidase activity is required for growth. This study explores ... -

(Asociación Latinoamericana de Producción Animal, 2020-12)La raza Criollo Argentino se caracteriza por su facilidad de parto. Dificultades en el momento de la parición pueden ocasionar pérdidas de terneros, mayores controles y asistencia de las hembras y pérdidas de vientres en ... -
Relationship between incidence and severity of peanut smut and its regional distribution in the main growing region of Argentina
(Springer, 2021-10-20)Peanut smut, caused by the soil-borne pathogen Thecaphora frezii, has increased in incidence in the main Argentinian peanut-growing regions. Smut-affected pod transform the kernel into a mass of teliospores, which survive ... -
Relative incidence of cucurbit viruses and relationship with bio-meteorological variables
(Springer, 2020-02)Environmental heterogeneity can shape the plant-virus relationship, furthering the appearance of new diseases in crops, or altering disease incidence and severity. In this work, we studied the virus association with ... -
