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 ... -
Shoot- and tuber-based critical nitrogen dilution curves for the prediction of the N status in potato
(Elsevier, 2020-09)Critical nitrogen (N) dilution curves describe the critical N concentration in plant tissues during crop growth and they are used to estimate the N nutriton status of whole plants in potato. Little is known, however, about ... -
The role of social capital and collective actions in natural capital conservation and management
(Elsevier, 2020-05)The relationships among social capital (SC) and collective actions (CA) for nature conservation and management were analyzed across five case studies characterised by specific land-use dynamics in the South American ... -
Maize transpiration efficiency increases with N supply or higher plant densities
(Elsevier, 2021-03-08)Most of the studies addressing the influence of management practices on seasonal crop water use efficiency (i.e., the ratio between shoot biomass and evapotranspiration in a seasonal scale, WUE(B, ET, s)) have focused on ... -
Gene expression and in vitro replication of bovine gammaherpesvirus type 4
(Springer Verlag, 2021-02-05)In vitro cell cultures are widely used models for dissecting cellular and molecular mechanisms that lead to certain physiological conditions and diseases. The pathogenesis of BoHV-4 in the bovine reproductive tract has ... -
Effect of zinc application strategies on maize grain yield and zinc concentration in mollisols
(Taylor and Francis, 2020-11-12)Maize (Zea mays L.) is highly susceptible to zinc (Zn) deficiency. Different application strategies (AS) can be utilized to improve grain yield (GY) and quality (Zn biofortification) by combining Zn fertilizer rate, source, ... -
Morphological and molecular variability of wild diploid and polyploid populations of Chrysolaena flexuosa (Sims) H. Rob: relevance for ornamental breeding
(Elsevier, 2020-01)Chrysolaena flexuosa is a South American species of ornamental interest, whose variability has not been explored. The objective of this work was to perform joint analyses of morphological and molecular traits in seven ... -
Evolution of grain microbiota during hermetic storage of corn (Zea mays L.)
(Elsevier, 2021-03-17)Respiration of biotic components of the grain ecosystem generates self-modified atmospheres (oxygen reduced and carbon dioxide enriched) during hermetic storage. The effect of temperature, moisture content and modified ... -
Stover biogas potential of corn crops grown under contrasting water availability and nitrogen supply
(Elsevier, 2020-12-31)Corn stover is a biogas feedstock capable of enhancing agriculture bioenergy potential. Although the influence of growing conditions on biogas yield of corn stover has been reported, the joint effects of water and nitrogen ... -
Over time variation in microsatellite (ssr) patterns in a natural wild potato population from northwest Argentina.
(Crop Science Society of America, 2021-02-26)The common potato, Solanum tuberosum L. (2n = 4x = 48), has 100–200 related wild taxonomic species endemic to the Americas, which constitute invaluable sources of genetic diversity. They form a polyploid series with 2n = ... -
Prediction of topsoil properties at field-scale by using C-band SAR data
(Elsevier, 2020-07-10)Designing and validating digital soil mapping (DSM) techniques can facilitate precision agriculture implementation. This study generates and validates a technique for the spatial prediction of soil properties based on ... -
Adequate vegetative cover decreases nitrous oxide emissions from cattle urine deposited in grazed pastures under rainy season conditions
(Nature Publishing, 2019-01-29)A decline in pasture productivity is often associated with a reduction in vegetative cover. We hypothesize that nitrogen (N) in urine deposited by grazing cattle on degraded pastures, with low vegetative cover, is highly ... -
Revaluation of waste from fishing industry through generation of chitosan coatings to improve quality and extend shelf-life of minimally processed lettuce
(Elsevier, 2020-07-24)Chitosan is obtained at industrial scale through a process of alkaline deacetylation of chitin the major waste of shrimp industry. Its utilization could both diminish industrial environmental impact and add value to foods ... -
Linking farmers' management decision, demographic characteristics and perceptions of ecosystem services in the Southern Pampa of Argentina
(Elsevier, 2020-03-15)In the Pampean region of Argentina, uncultivated areas with spontaneous vegetation, such as the sierras (low hills), are important sites for nature conservation. In the last decades, the “agriculturization” process has ... -
