Evidence of Recombinant Isolates of Potato Virus Y (PVY) in Argentina
(Springer Netherlands, 2017-06)In order to make a first approach in the identification of the genetic diversity of Potato virus Y (PVY) in Argentina, 46 PVY isolates from different potato growing regions of Argentina were characterized both, biological ... -
Improving Yield and Quality of Processing Potato Crops Grown in the Argentinian Pampas: the Role of N, P and S and Their Impact on CO2 Emissions
(Springer Netherlands, 2018-03-17)The area grown with processing potato crops in the Argentinian Pampas has been increasing steadily since 1995. The aim of this work was to assess the effects of N, P and S upon yield and tuber quality and their impact on ... -
Characterization of a deletion in the Hsp70 cluster in the bovine reference genome
(Wiley Online Library, 2017-07-11)The 70 kilodalton heat shock proteins (Hsp70) are highly conserved molecular chaperones which have a crucial role in the stress response of the cell. In mammals, the Hsp70 proteins are encoded by a cluster of three genes: ... -
Cold sweetening diversity in Andean potato germplasm from Argentina
(Wiley Online Library, 2018-04-02)BACKGROUND: Cold induced sweetening (CIS) is the accumulation of sucrose and reducing sugars in potato tubers at low temperatures. This process is central for the potato processing industry. During potato chip and French ... -
Water regulation by grasslands: a global meta‐analysis
(Wiley Online Library, 2018-06-03)Grasslands have been modified and replaced worldwide and have affected water regulation ecosystem services. In order to support public policies attending to the consequences of different grassland modifications and ... -
Exogenous human OKSM factors maintain pluripotency gene expression of bovine and porcine iPS-like cells obtained with STEMCCA delivery system
(BioMedCentral, 2018-07-27)OBJECTIVES: The use of induced pluripotent stem (iPS) cells as an alternative to embryonic stem cells to produce transgenic animals requires the development of a biotechnological platform for their generation. In this ... -
Effects of photoperiod sensitivity genes Ppd‐B1 and Ppd‐D1 on spike fertility and related traits in bread wheat
(Wiley Online Library, 2018-04-27)Increasing grain yield is a key breeding goal in bread wheat. Several authors have suggested that a spike fertility index (SF), that is the quotient between grain number per unit spike (GNS) and spikechaff dry weight (SCDW), ... -
Natural infection in Pampas fox (Lycalopex gymnocercus) by Lagochilascaris major Leiper, 1910 (Nematoda: Ascarididae) in Buenos Aires, Argentina
(Springer Netherlands, 2018-06-15)Lagochilascariosis is an emerging parasitic disease limited to the American continent, caused by nematodes of the genus Lagochilascaris. Its life cycle is heteroxenous, involving natural definitive hosts (wild carnivores), ... -
Selection for high spike fertility index increases genetic progress in grain yield and stability in bread wheat
(Springer Netherlands, 2018-07-18)Spike fertility index (SF) has been proposed as a promising trait to be used as a selection criterion in wheat breeding programs aimed at increasing grain yield, but no actual evidence of its successful application has ... -
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 ... -
Non-point source pollution of glyphosate and AMPA in a rural basin from the southeast Pampas, Argentina
(2018-03)We measured the occurrence and seasonal variations of glyphosate and its metabolite, aminomethylphosphonic acid (AMPA), in different environmental compartments within the limits of an agricultural basin. This topic is of ... -
Vaginal mucus from ewes treated with progestogen sponges affects quality of ram spermatozoa
(2016)The use of intravaginal sponges (IS) to synchronize estrous onset in ewes provokes vaginitis, an increase in the vaginal bacterial load, and growth of bacterial species that are not present during spontaneous estrous ... -
Changes in the vaginal microbiota in ewes after insertion of intravaginal sponges at different stages of the oestrous cycle
(2018)The aims of this study were to determine if the ewe’ vaginal bacterial load differs according to the stage of the oestrous cycle; and thus, if the stage of the oestrous cycle when intravaginal sponges (IS) used for ... -
Cultural ecosystem services trade-offs arising from agriculturization in Argentina : a case study in Mar Chiquita Basin
(2018-02)Highlights •We developed a spatial indicator to assess opportunities for recreation and tourism. •We found trade-offs between agricultural commodities and this indicator. •Spatially represented, trade-off was diffuse ... -
Delineation of management zones to improve nitrogen management of wheat
(2015-01)Site-specific management of N (NSSM) is an attractive and intuitive approach to increasing N fertilizer use efficiency (NUE) of agricultural systems by adjusting fertilizer rates to the soil characteristics. The objective ... -
Proceso de institucionalización de la agricultura familiar y nuevo referencial para el desarrollo rural en la Argentina
(2015-04)Este artículo pone en relieve las ideas y los intereses políticos y económicos que condujeron a la reciente institucionalización de la agricultura familiar en la Argentina. Este sector, que fue motor de la primera ... -
Soybean shows an attenuated nitrogen dilution curve irrespective of maturity group and sowing date
(2016-02-01)It is generally accepted that the nitrogen (N) dilution curves relating shoot nitrogen concentration (%N) and shoot biomass (W) are similar among genotypes from the same species. However, differences in the pattern of ... -
