Is N-feedback involved in the inhibition of nitrogen fixation in drought-stressed Medicago truncatula?
(Oxford University PressSociety for Experimental Biology, 2013)
Artículo / Artikulua,
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 ...
Local inhibition of nitrogen fixation and nodule metabolism in drought-stressed soybean
(Oxford University PressSociety for Experimental Biology, 2013)
Artículo / Artikulua,
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 ...
Proteolytic pathways induced by herbicides that inhibit amino acid biosynthesis
(Public Library of Science, 2013)
Artículo / Artikulua,
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 ...
Phytotoxic and metabolic effects of exogenous quinate on Pisum sativum L.
(Springer US, 2013)
Artículo / Artikulua,
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 ...
Branched-chain amino acid biosynthesis inhibitors: herbicide efficacy is associated with an induced carbon–nitrogen imbalance
(Elsevier, 2013)
Artículo / Artikulua,
Acetolactate synthase (ALS; EC 4.1.3.18) and ketol-acid reductoisomerase (KARI; EC 1.1.1.86) are two consecutive enzymes in the biosynthesis of branched-chain amino acids. Several commercial herbicides inhibit ALS as their ...
Importancia de la caracterización de la biomasa de raíces en la simulación de ecosistemas forestales
(Asociación Española de Ecología Terrestre, 2013)
Artículo / Artikulua,
Los análisis de sensibilidad son una herramienta importante para comprender el funcionamiento de los modelos ecológicos, así como para identificar
los parámetros más importantes en su funcionamiento. Además, los análisis ...
Modelos ecológicos: descripción, explicación y predición
(Asociación Española de Ecología Terrestre, 2013)
Artículo / Artikulua,
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 ...
Evaluation of the effects of forest management strategies on carbon sequestration in evergreen broad-leaved (Phoebe bournei) plantation forests using FORECAST ecosystem model
(Elsevier, 2013)
Artículo / Artikulua,
In the context of global climate change, it is critical to study how different forest management
practices affect forest carbon sequestration. This is especially important for forest managers
and policy makers who will ...
¿Puede haber carrascales en el sur de Navarra? Una aproximación mediante la modelización de distribución de especies
(Asociación Española de Ecología Terrestre, 2013)
info:eu-repo/semantics/article,
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 ...
Pea plant responsiveness under elevated [CO2] is conditioned by the N source (N2 fixation versus NO3 fertilization)
(Elsevier, 2013)
info:eu-repo/semantics/article,
The main goal of this study was to test the effect of [CO2] on C and N management in 2different plant organs (shoots, roots and nodules) and its implication in the 3responsiveness of exclusively ...
