Dissecting maize diversity in lowland South America : genetic structure and geographic distribution models
(2016)Background: Maize landraces from South America have traditionally been assigned to two main categories: Andean and Tropical Lowland germplasm. However, the genetic structure and affiliations of the lowland gene pools have ... -
Evaluación del manejo de residuos porcinos de un sistema intensivo y semi-intensivo. Su caracterización, estabilización y aplicación de efluente y compost sobre la matriz suelo y planta
(Facultad de Agronomía, Universidad de Buenos Aires, 2019-11-05)La cría intensificada y semi-intensificada de cerdos genera la acumulación de estiércoles y efluentes, los cuales, si no son estabilizados, generan un impacto negativo en el ambiente. El compostaje es un proceso aeróbico ... -
Factores extrínsecos e intrínsecos asociados a poblaciones fúngicas micotoxigénicas de granos de maíz (Zea mays L.) almacenados en silos bolsa en Argentina = Extrinsic and intrinsic factors associated with mycotoxigenic fungi populations of maize grains (Zea mays L.) stored in silobags in Argentina
(Asociación Argentina de Microbiología, 2015-10)Con el objeto de caracterizar las poblaciones fúngicas, en particular las especies potencialmente micotoxigénicas, que pueden contaminar los granos de maíz almacenados en silos bolsa con un contenido de humedad superior ... -
Genetic diversity of maize landraces from lowland and highland agro‐ecosystems of Southern South America: implications for the conservation of native resources
(Wiley, 2012-05)The North of Argentina is one of the southernmost areas of maize landrace cultivation. Two distinct centres of diversity have been distinguished within this region: Northwestern Argentina (NWA), and Northeastern Argentina ... -
Genome-wide diversity in lowland and highland maize landraces from southern South America: population genetics insights to assist conservation
(BioRxiv, 2024-02)Maize (Zea mays ssp. mays L.) landraces are traditional American crops with high genetic variability that conform a source of original alleles for conventional maize breeding. Northern Argentina, one the southernmost regions ... -
In vitro PGPR properties and osmotic tolerance of different Azospirillum native strains and their effects on growth of maize under drought stress
(2017-09)Osmotic variations in the soil can affect bacterial growth diminishing the number of inoculated bacteria. In a scenario of water deficit having tolerant bacteria would be beneficial to achieve a better response of the plant ... -
Inoculation with Azospirillum argentinense Az19 improves the yield of maize subjected to water deficit at key stages of plant development = La inoculación con Azospirillum argentinense Az19 mejora el rendimiento del maíz expuesto a déficit hídrico durante estadios clave del desarrollo vegetal
(Elsevier, 2023-07)Water deficit constitutes a severe limitation to agricultural productivity. In the context of sustainable crop production, the potential of microbial biotechnology to increase plant drought tolerance and improve crop yields ... -
Mal de Río Cuarto virus (MRCV) genomic segment S3 codes for the major core capsid protein
(Springer, 2009-06)Mal de Río Cuarto virus (MRCV) is a newly described species of the genus Fijivirus, family Reoviridae. Compared with other plant-infecting genus of the family, the function and localization of MRCV and other Fijivirus ... -
Morphological and genetic diversity of maize landraces along an altitudinal gradient in the Southern Andes
