Evaluation of bradyrhizobia strains isolated from field-grown soybean plants in Argentina as improved inoculants
(Springer, 2010-09-22)Bradyrhizobium strains were isolated from nodules obtained from field-grown soybean plants sampled in 12 soybean production locations in Argentina. These fields had been annually cropped with soybean and did not show ... -
Evolutionary insights into FYVE and PHOX effector proteins from the moss Physcomitrella patens
(Springer, 2020-02)Phosphatidylinositol 3-phosphate (PtdIns3P) is a signaling phospholipid, which regulates several aspects of plant growth and development, as well as responses to biotic and abiotic stresses. The mechanistic insights ... -
Expression of animal anti-apoptotic gene ced-9 enhances tolerance during Glycine max L.– Bradyrhizobium japonicum interaction under saline stress but reduces nodule formation
(2014-07-27)The mechanisms by which the expression of animal cell death suppressors in economically important plants conferred enhanced stress tolerance are not fully understood. In the present work, the effect of expression of animal ... -
Los extractos vegetales como artefacto tecnológico para la transición agroecológica: experiencias de prueba en Córdoba, Argentina
(Facultad de Ciencias Agrarias, Universidad Nacional del Litoral, 2023-07-06)Este artículo analiza dos Marcos Tecnológicos en disputa vigentes en la Región Agroalimentaria de Córdoba Centro: el convencional (MTC), con una presencia dominante en el sector agropecuario y el agroecológico (MTAE), con ... -
Factors Affecting Tocopherol Concentrations in Soybean Seeds
(American Chemical Society, 2016-10-31)Soybean seeds contain several health-beneficial compounds, including tocopherols, which are used by the nutraceutical and functional food industries. Soybean tocopherol concentrations are, however, highly variable. Large ... -
Feasibility of lowering soybean planting density without compromising nitrogen fixation and yield
(American Society of Agronomy, 2014)Adjusting soybean [Glycine max (L.) Merrill] density can be critical to reduce inter-plant competition for water, nutrients, and sunlight, and to increase intercepted radiation, photosynthesis, and biomass production. The ... -
Floral nectaries of Heliocarpus popayanensis and Luehea divaricata (Malvaceae-Grewioideae): structure and ultrastructure
(2018-03)The structure and ultrastructure on floral nectaries of Heliocarpus popayanensis Kunth. and Luehea divaricata Mart (Malvaceae-Grewioideae) were investigated for the first time. The floral nectaries of the analysed species ... -
Formulación y propiedades de biopolímero de recubrimiento para semillas de maní (Arachis hypogaea L.)
(Facultad de Ciencias Agropecuarias, Universidad Nacional de Córdoba, 2021-06-30)En este trabajo se presenta el diseño de una biopelícula de recubrimiento biodegradable, formulada con macromoléculas naturales como almidón, proteína y glicerol para ser aplicada sobre semillas de maní, a fin de aumentar ... -
Genetic variability for responses to short‐ and long‐term salt stress in vegetative sunflower plants
(Wiley, 2012-12)Sunflower (Helianthus annuus L.) has been rated as moderately salt‐resistant, and variability for salt resistance has been detected within this crop. However, variability in salt‐resistance mechanisms has not been assessed. ... -
Genotypic variation in response to salinity in a new sexual germplasm of Cenchrus ciliaris L.
(2016)As part of breeding program for new salt- tolerant sexual genotypes of Cenchrus ciliaris L., we evaluated the salt- stress response of two new sexual hybrids, obtained by controlled crosses, at seedling and germination stages. -
Germination characteristics of five coexisting neotropical species of Acacia in seasonally dry Chaco forests in Argentina
(Wiley, 2017-04)At a regional scale, habitat heterogeneity can play a very important role in allowing the coexistence of species through their specialization in the use of patches differing in environmental conditions. Here, we explore ... -
Glutathione, a key compound for As accumulation and tolerance in soybean plants treated with AsV and AsIII
(Elsevier, 2019-06)Despite soybean (Glycine max L.) is often cultivated in areas contaminated with arsenic (As) which causes deleterious effects on its growth, little is known about tolerance mechanisms in response to As exposure. In particular, ... -
