Amylose starch with no detectable branching developed through DNA-free CRISPR-Cas9 mediated mutagenesis of two starch branching enzymes in potato
(Nature Publishing Group, 2021-02-22)DNA-free genome editing was used to induce mutations in one or two branching enzyme genes (Sbe) in tetraploid potato to develop starch with an increased amylose ratio and elongated amylopectin chains. By using ribonucleoprotein ... -
An architectural analysis of the elongation of field-grown sunflower root systems. Elements for modelling the effects of temperature and intercepted radiation
(Society for Experimental Biology, 1996-03)The effects of photosynthetic photon flux density (PPFD) and soil temperature on root system elongation rate have been analysed by using an architectural framework. Root elongation rate was analysed by considering three ... -
An insight into population structure and genetic progress of Argentinean Holstein cattle
(Wiley, 2023-02)The objective of the present study was to investigate the most critical issues associated with the limited genetic progress evidenced in the Argentinean Holstein (“Holando Argentino”) breed in the last 20 years (only 26% ... -
An integrative index of Ecosystem Services provision based on remotely sensed data
(Elsevier, 2016-12)We present an approach to generate estimates and to map Ecosystem Services (ES) related to C and water dynamics (Soil Carbon sequestration, evapotranspiration and groundwater recharge) and biodiversity (Avian Richness) ... -
Analysis of Genetic Variability in the Argentine Polo Horse With a Panel of Microsatellite Markers
(Elsevier, 2020-11)Argentine Polo (AP) is a young horse breed with a fast expansion because of an open registry policy and the application of assisted reproduction technologies. In the last years, AP showed a remarkable progress associated ... -
Analysis of sink/source relations in bread wheat recombinant inbred lines and commercial cultivars under a high yield potential environment
(2018-02)Grain yield in wheat is generally considered to be sink-limited during grain filling. But is this limitation inherent to the crop species or a consequence of the breeding process? A way to ascertain this is by using genetic ... -
Analysis of storage conditions of a wheat silo-bag for different weather conditions by computer simulation
(Elsevier, 2013-12)A validated mathematical model was used to analyse grain storage condition and determine the change in concentration of CO2 in a silo-bag holding wheat from summer to winter for a typical productive region with sub-tropical ... -
Anaplasmosis bovina en provincia de Buenos Aires durante 2015
(Ediciones INTA, 2021-04-21)Anaplasma marginale es una bacteria intracelular que infecta eritrocitos del bovino produciendo hemolisis extravascular y anemia. La anaplasmosis es endémica en regiones tropicales y subtropicales, mientras que en zonas ... -
Análisis de la disponibilidad de agua útil del suelo en plantaciones de kiwi (Actinidia deliciosa A. Chev) del sudeste bonaerense
(Ediciones INTA, 2021-04)El sudeste de la provincia de Buenos Aires concentra la mitad de la superficie plantada con kiwi en Argentina. Los productores de la zona no disponen de un plan de riego acorde a las características del suelo que permita ... -
¿El análisis de suelo permite diagnosticar la deficiencia de zinc en el cultivo de maíz?
(2015-09)El desarrollo de métodos adecuados de diagnóstico para evaluar la disponibilidad de Zn es clave para un manejo racional del mismo. El extractante más utilizado es el ácido dietilen triamino penta acético (DTPA) propuesto por ... -
Animal and forage responses on lucerne (Medicago sativa L.) pastures under contrasting grazing managements in a temperate climate
(Wiley, 2020-06)This study determined the impact of a change in grazing system on beef production from lucerne pastures in Argentina. One system (T500) used the traditional recommendation to commence grazing in spring when lucerne was ... -
