Is N-feedback involved in the inhibition of nitrogen fixation in drought-stressed Medicago truncatula?
Drought stress is a major factor limiting nitrogen fixation (NF) in crop production. However, the regulatory mechanism involved and the origin of the inhibition, whether local or systemic, is still controversial and so far ... -
Land use change effects on carbon and nitrogen stocks in the Pyrenees during the last 150 years: a modelling approach
In the southern Pyrenees, human population and therefore land uses have changed from forests to pastures, then crops, and back to pastures and secondary forests during the last two centuries. To understand what such rapid ... -
Local inhibition of nitrogen fixation and nodule metabolism in drought-stressed soybean
Drought stress is a major factor limiting symbiotic nitrogen fixation (NF) in soybean crop production. However, the regulatory mechanisms involved in this inhibition are still controversial. Soybean plants were symbiotically ... -
Long-term mannitol-induced osmotic stress leads to stomatal closure, carbohydrate accumulation and changes in leaf elasticity in Phaselous vulgaris leaves
The effect of long-term osmotic stress was investigated in leaves of two common bean lines, with contrasting tolerance: Flamingo (tolerant) and coco blanc (sensitive). Water relations, organic solute, ion accumulation ... -
Más allá de los modelos de crecimiento: modelos ecológicos híbridos en el contexto del manejo forestal sostenible
El desafío actual en el manejo forestal es la planificación de suministros sostenibles de madera y otros valores forestales, a la vez que se preserva la integridad del ecosistema forestal. En conse- cuencia, el uso de ... -
Meat waste as feedstock for home composting: effects on the process and quality of compost
Home composting is a powerful tool, which is spreading in different parts of the world, to reduce the generation of municipal waste. However, there is debate concerning the appropriateness, in terms of domestic hygiene and ... -
Modelling the management of forest ecosystems: importance of wood decomposition
Scarce and uncertain data on woody debris decomposition rates are available for calibrating forest ecosystem models, owing to the difficulty of their empirical estimations. Using field data from three experimental sites which ... -
Modelos ecológicos: descripción, explicación y predición
Los ecosistemas son, por definición, complejos sistemas en los que factores biológicos, climáticos y geológicos se combinan con factores sociales, políticos y económicos para producir una serie de procesos ambientales que ... -
Multiple pathway succession in coastal Tsuga heterophylla, Thuja plicata and Abies amabilis forests on northeastern Vancouver Island, British Columbia
Sustainable forest practices are often designed to mimic natural disturbance and successional processes, yet succession is poorly understood in many ecosystems. On northeastern Vancouver Island, the ‘disturbance hypothesis’ ... -
Nodule carbohydrate catabolism is enhanced in the Medicago truncatula A17-Sinorhizobium medicae WSM419 symbiosis
The symbiotic association between Medicago truncatula and Sinorhizobium meliloti is a well-established model system in the legume–Rhizobium community. Despite its wide use, the symbiotic efficiency of this model has been ... -
Nutritional value of raw and extruded chickpeas (Cicer arietinum L.) for growing chickens
(Instituto Nacional de Investigación y Tecnología Agraria y Alimentaria (INIA), 2008) Artículo / ArtikuluaSe realizó un experimento con el objeto de estudiar el efecto de la inclusión de distintas concentraciones (0, 100, 200 y 300 g kg-1) de garbanzo crudo y extrusionado sobre los parámetros productivos, el peso y la longitud ... -
Papel de los factores bióticos y las sequías en el decaimiento del bosque: aportaciones desde la dendroecología
El aumento de la mortalidad y la pérdida de vitalidad de los bosques son procesos que afectan a diversas especies de árboles y biomas. Estos fenómenos de decaimiento forestal se han asociado a la interacción de múltiples ... -
The pattern of shikimate pathway and phenylpropanoids after inhibition by glyphosate or quinate feeding in pea roots
The shikimate pathway is a metabolic route for the biosynthesis of aromatic amino acids (AAAs) (i.e. phenylalanine, tyrosine, and tryptophan). A key enzyme of shikimate pathway (5-enolpyruvylshikimate-3-phosphate synthase, ... -
Pedogenic, mineralogical and land-use controls on organic carbon stabilization in two contrasting soils
Organo-mineral complexation in soils is strongly controlled by pedogenesis, but the mechanisms controlling it and its interaction with cultivation are not yet well understood. We compared the mineralogy and quality of ... -
Physiological responses of legume nodules to drought
Legumes include important agricultural crops, as their high protein content is of primary importance for human food and animal feed. In addition, the ability of most of them to establish symbiotic relationships with soil ... -
Phytotoxic and metabolic effects of exogenous quinate on Pisum sativum L.
Quinate (1,3,4,5-tetrahydroxycyclohexanecarboxylate) is a compound synthesized in plants through a side branch of the shikimate biosynthesis pathway. Plants treated with herbicides that inhibit amino acid biosynthesis ... -
Los precedentes y las respuestas de los árboles a sequías extremas revelan los procesos involucrados en el decaimiento de bosques mediterráneos de coníferas
¿Qué determina la vulnerabilidad de las especies de árboles frente a eventos climáticos extremos en el contexto actual de calentamiento global? Sabemos que las sequías severas contribuyen al decaimiento del bosque pero ... -
Protein kinase GCN2 mediates responses to glyphosate in Arabidopsis
Background: The increased selection pressure of the herbicide glyphosate has played a role in the evolution of glyphosate-resistance in weedy species, an issue that is becoming a threat to global agriculture. The molecular ... -
Proteolytic pathways induced by herbicides that inhibit amino acid biosynthesis
Background: The herbicides glyphosate (Gly) and imazamox (Imx) inhibit the biosynthesis of aromatic and branched-chain amino acids, respectively. Although these herbicides inhibit different pathways, they have been reported ... -
¿Puede haber carrascales en el sur de Navarra? Una aproximación mediante la modelización de distribución de especies
De acuerdo con algunos mapas de vegetación potencial diversos factores climáticos y edáficos limitan el hábitat disponible para los bosques de carrasca (Quercus rotundifolia) en el sur de Navarra (NE de España). Este es ...
