Both free indole-3-acetic acid and photosynthetic performance are important players in the response of Medicago truncatula to urea and ammonium nutrition under axenic conditions
We aimed to identify the early stress response and plant performance of Medicago truncatula growing in axenic medium with ammonium or urea as the sole source of nitrogen, with respect to nitrate-based nutrition. Biomass ... -
The importance of the urea cycle and its relationships to polyamine metabolism during ammonium stress in Medicago truncatula
The ornithine–urea cycle (urea cycle) makes a signifcant contribution to the metabolic responses of lower photosynthetic eukaryotes to episodes of high nitrogen availability. In this study, we compared the role of the plant ... -
An integrated view of changing nutrient availability in model species: the role of signaling in the plant response
Las plantas tienen que hacer frente a situaciones cambiantes en cuanto a la disponibilidad de nutrientes, por ese motivo en la presente tesis se ha estudiado la respuesta de (i) Arabidopsis thaliana frente a la deficiencia ... -
Nitric oxide induces the alternative oxidase pathway in Arabidopsis seedlings deprived of inorganic phosphate
Phosphate starvation compromises electron flow through the cytochrome pathway of the mitochondrial electron transport chain, and plants commonly respond to phosphate deprivation by increasing flow through the alternative ... -
The proteome of Medicago truncatula in response to ammonium and urea nutrition reveals the role of membrane proteins and enzymes of root lignification
Plants differ widely in their growth and tolerance responses to ammonium and urea nutrition, while derived phenotypes seem markedly different from plants grown under nitrate supply. Plant responses to N sources are complex, ...
