Early responses to Fe-deficiency distinguish Sorghum bicolor genotypes with contrasting alkalinity tolerance
(Elsevier, 2018-11)Soil alkalinity is a significant limitation to agricultural productivity and it is associated to several soil features, among them, Fe deficiencies. In this work, we explored the hypothesis that alkalinity tolerance in ... -
Changes in the relationship between temperature during the seed‐filling period and soya bean seed isoflavones under water‐deficit conditions
(Blackwell, 2016-12)Isoflavones have been shown to have health‐promoting activities in humans and are particularly abundant in soya bean. This study was conducted to determine how water deficit during seed fill affects the already known ... -
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 ... -
Biological nitrogen fixation in soybean in Argentina: relationships with crop, soil, and meteorological factors
(2015-07)Aims: This study aims to (i) asses the contribution of biological N fixation (%Ndfa) in the soybean production area of Argentina, (ii) build a model for predicting %Ndfa using crop, soil, and meteorological variables, and ... -
Conocimiento de las bases fisiológicas, bioquímicas, y moleculares de la colonización en la simbiosis hongos micorricicos arbusculares- soja domesticación vs no domesticación
(Edición de Autor, 2018-03-10)La soja (Glycine max) es uno de los cultivos más desarrollados en Argentina. En las últimas décadas la siembra directa y el empleo de variedades genéticamente modificadas favorecieron una masiva expansión del cultivo, ... -
Caracterización de germoplasma de Panicum coloratum L. VAR. coloratum para la tolerancia a la salinidad, alcalinidad y al frío
(Edición del Autor, 2017-11)Los resultados demostraron que la población colectada de P. coloratum fue más tolerante a la salinidad que el cultivar comercial `Klein´. La variabilidad interna de esta población, en el crecimiento de los materiales en ... -
Assessment of genetic and epigenetic changes in virus-free garlic (Allium sativum L.) plants obtained by meristem culture followed by in vitro propagation
(2016-01)Garlic (Allium sativum) is a worldwide crop of economic importance susceptible to viral infections that can cause significant yield losses. Meristem tissue culture is the most employed method to sanitize elite cultivars. ... -
Somatic embryogenesis from in vitro anther culture of apomictic buffel grass genotypes and analysis of regenerated plants using flow cytometry
(2014-06)Buffel grass is a fodder grass that reproduces mainly via apomixis. Using in vitro tissue culture in apomictic species provides alternatives that can be applied in a breeding program. The aims of this work were to establish ... -
Drought induces distinct growth response, protection, and recovery mechanisms in the maize leaf growth zone
(2015-10)Drought is the most important crop yield-limiting factor, and detailed knowledge of its impact on plant growth regulation is crucial. The maize (Zea mays) leaf growth zone offers unique possibilities for studying the ... -
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. -
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 ... -
Cultivo in vitro de anteras como estrategia para el mejoramiento genético de Buffelgrass (Cenchrus ciliaris L)
(Facultad de Ciencias Agropecuarias, Universidad Nacional de Córdoba, 2016)Buffelgrass es una gramínea forrajera que se reproduce principalmente por apomixis. El objetivo del presente trabajo es generar variabilidad genética, mediante cultivo in vitro, en caracteres asociados a tolerancia a sequía ...
