Wild potato genetic reserves in protected areas: prospection notes from Los Cardones National Park, Salta, Argentina
(Facultad de Ciencias Agrarias, Universidad Nacional de Cuyo, 2019-12-09)Wild potato species (WPS) are vital genetic resources to improve the productivity and sustainability of the third most important food crop worldwide. Although in situ conservation of this germplasm has been considered the ... -
Controlling endemic Neospora caninum-related abortions in a dairy herd from Argentina
(Frontiers Media, Switzerland, 2019-12-12)After diagnosis of endemic abortions due to neosporosis in a commercial dairy farm, routes of Neospora caninum-transmission were evaluated in order to choose the best strategy for reducing its seroprevalence and related ... -
Stand density management diagrams of Eucalyptus Viminalis: predicting stem volume, biomass and canopy cover for different production purposes
(Universidade Federal de Lavras, 2019-12-13)Stand density management diagrams (SDMD) provide a guide for forest density management taking into account stands attributes such as trees´ diameter or volume. One of the most common species planted in Pampean plains of ... -
New insights into wood anatomy and function relationships: how Eucalyptus challenges what we already know
(Elsevier, 2019-12-15)Multispecies surveys have shown that there is a weak but significant trade-off between xylem efficiency and safety in woody species, with no species maximizing both attributes at the same time. Relationships between xylem ... -
Distinctive features of bovine alphaherpesvirus types 1 and 5 and the virus-host interactions that might influence clinical outcomes
(Springer, 2019-12-16)Bovine herpesvirus types 1 (BoHV-1) and 5 (BoHV-5) are two closely related alpha-herpesviruses. BoHV-1 causes several syndromes in cattle, including respiratory disease and sporadic cases of encephalitis, whereas BoHV-5 ... -
La intermediación solidaria en el suministro de hortalizas agroecológicas en el contexto del COVID-19.
(Associação Brasileira de Agroecologia, 2020)El sistema alimentario se encuentra en crisis, evidenciando problemas de sostenibilidad. Este modelo coexiste con formas alternativas de producción, distribución y consumo de alimentos. Este artículo se propone analizar ... -
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 ... -
Isolation of streptomycetes causing common scab from 3-years old potato samples from South America
(Estonian Agricultural University, 2020-01)In this paper, we aimed at assessing the best conditions for the isolation of actinobacteria from old potato samples. A set of media and pretreatments were tested. The optimal were chosen for the isolation of actinobacteria ... -
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 ... -
Soil organic carbon in cropping sequences with predominance of soya bean in the argentinean humid Pampas
(Wiley, 2020-01)Soya bean (Glycine max (L.) Merr.) monoculture can lead to a decrease in labile fractions of soil organic carbon (SOC). This study sought to evaluate the effects of cover crops (CC), application of fertilizer, and crop ... -
Plant interactions and ergovaline concentration in mixture of Lotus tenuis and Schedonorus arundinaceus infected with the fungus Epichloë coenophiala
(Asociación Argentina de Ecología, 2020-01-08)Schedonorus arundinaceus (tall fescue) population can be infected by the endophyte fungus Epichloë coenophiala, responsible of livestock intoxication due to fungal alkaloids (i.e., ergovaline). The effects of ergovaline in ... -
Reduced enzymatic browning in potato tubers by specific editing of a Polyphenol oxidase gene via Ribonucleoprotein complexes delivery of the CRISPR/Cas9 System.
(Frontiers Media, Switzerland, 2020-01-09)Polyphenol Oxidases (PPOs) catalyze the conversion of phenolic substrates to quinones, leading to the formation of dark-colored precipitates in fruits and vegetables. This process, known as enzymatic browning, is the cause ... -
Improving concentration of healthy fatty acids in milk, cheese and yogurt by adding a blend of soybean and fish oils to the ration of confined dairy cows
(2020-01-18)Compared to pasture based sistems, milk produced in confined dairy systems is characterized by a high saturated fat (SF) content with a lower concentration of healthy fatty acids (FA) such as vaccenic (VA, trans-11C18:1), ... -
