Genomic evolution of bovine viral diarrhea virus based on complete genome and individual gene analyses
(Springer, 2023-05-23)Bovine viral diarrhea virus (BVDV) genome consists of a single-stranded, positive-sense RNA with high genetic diversity. In the last years, significant progress has been achieved in BVDV knowledge evolution through ... -
Genomic relationships between hexaploid Helianthus resinosus and diploid Helianthus annuus (Asteraceae)
(Springer, 2014-05)Genus Helianthus comprises diploid and polyploid species. An autoallopolyploid origin has been proposed for hexaploid species but the genomic relationships remain unclear. Mitotic and meiotic studies in annual Helianthus ... -
Germinación de dos especies de Rhynchosia (Fabaceae) nativas de Argentina central útiles para la restauración productiva de pastizales naturales
(Ediciones INTA, 2021-04)Los pastizales naturales del sudoeste de la provincia de Buenos Aires (Argentina) están degradados como resultado del sobrepastoreo y de la expansión de la agricultura, que han generado un fuerte impacto en la biodiversidad ... -
Germination and emergence of corn (Zea mays, L) as a function of soil physical parameters
(Oregon State University, 1988-12)Rates of germination and emergence of corn were measured as influenced by soil physical parameters using blotter paper and a sandy loam soil as growth media. The corn seeds used were a hybrid of Funk's (DJ7xLH93). Experimental ... -

(EEA Hilario Ascasubi, INTA, 2019-08)En el marco de las actividades realizadas para la diversificación productiva del valle, el trabajo se focalizó en la adopción del cultivo de papa como alternativa y complemento al cultivo de cebolla. Este proceso se inició ... -
La gestión sustentable del territorio en escala microrregional. El caso de Villa Regina y la microrregión del Alto Valle Este
(Facultad de Ingeniería, Universidad Nacional del Comahue, 2020-05)El propósito de este trabajo de investigación es presentar la Tesis de Maestría, para optar al título de Magister en Intervención Ambiental, Orientación Gestión Ambiental de las Organizaciones, que se dicta en la Facultad ... -
Glyphosate and aminomethylphosphonic acid (AMPA) are commonly found in urban streams and wetlands of Melbourne, Australia
(Elsevier, 2020-01)Glyphosate is the most widely-used pesticide for weed control in agriculture and in urban and residential areas. This is the first study to quantify glyphosate and AMPA levels in surface water in Australia from different ... -
Glyphosate and AMPA concentrations in the respirable dust emitted experimentally by soil aggregates, shortly after herbicide application
(Elsevier, 2020-06-15)The objective of this study was to analyze glyphosate- and aminomethylphosphonic acid (AMPA) concentrations in the respirable dust (RD) emitted by different soil aggregates, shortly after herbicide application in a field ... -
Glyphosate and AMPA concentrations in wind‐blown material under field conditions
(Wiley Online Library, 2018-03-01)Agricultural intensification in fragile arid and semiarid environments has led to an increase in soil degradation, mainly through wind erosion. Argentina is an agricultural and cattle‐farming country, which has increased ... -
Glyphosate and nutrient retention in preferential flow pathways
(Asociación Argentina de Ecología, 2019-12)Riparian vegetation strips (RVS) reduce surface runoff volume and retain sediments, pesticides and nutrients that are transported across them from adjacent crop-fields (CF). The ability of these strips to retain glyphosate ... -
Glyphosate Biodegradation Potential in Soil Based on Glycine Oxidase Gene (thiO) from Bradyrhizobium
(Springer Nature, 2021-04-02)Despite the intensive use of glyphosate (GP) and its ubiquitous presence in the environment, studies addressing the presence of microbial genes involved in glyphosate degradation in natural conditions are scarce. Based on ... -
Glyphosate dynamics in a soil under conventional and no-till systems during a soybean growing season
(2018-08-01)Glyphosate (GLY) is a non-selective herbicide, heavily used world-wide in agriculture, especially under no-tillage (NT) management. The objectives of this work were i - to determine the temporal and vertical variation of ... -
Glyphosate effects on gas exchange and chlorophyll fluorescence responses of two Lolium perenne L. biotypes with differential herbicide sensitivity
(2012-08)Despite the extensive use of glyphosate, how it alters the physiology and metabolism of plants is still unclear. Photosynthesis is not regarded to be a primary inhibitory target of glyphosate, but it has been reported to ... -
Glyphosate resistance in perennial ryegrass (Lolium perenne L.) from Argentina
(2012-02)In Argentina, glyphosate is the most widely used herbicide. A population of perennial ryegrass, subjected to two glyphosate applications per year during twelve years, was putatively identified as glyphosate-resistant based ... -
Glyphosate retention in grassland riparian areas is reduced by the invasion of exotic trees = La retención de glifosato en las áreas ribereñas con pastizales se reduce por la invasión de árboles exóticos
(Fundación Rómulo Raggio, 2016)In this study, we examined some aspects regarding the effect of willow trees (Salix fragilis L.) invasion of grassland riparian environments in the Argentinean Pampas on the runoff reduction, sedimentation and glyphosate ... -
Glyphosate runoff and its occurrence in rainwater and subsurface soil in the nearby area of agricultural fields in Argentina
(Elsevier, 2019-06)Glyphosate-based products are among the most important herbicides applied to enhance the production of food commodities, leading to the worldwide spread of this herbicide. The main goal of this work was to evaluate the ... -
