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 ... -
Herbicidas alternativos en viña ecológica
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2017) Contribución a congreso / Biltzarrerako ekarpenaEn el año 2009 se realizó un ensayo con diferentes productos herbicidas alternativos y aplicables en agricultura ecológica. Se aplicó vinagre del 6% de ácido acético pulverizado directamente a 300 l/ha y 600 l/ha, dos ... -
IAOx induces the SUR phenotype and differential signalling from IAA under different types of nitrogen nutrition in Medicago truncatula roots
Indole-3-acetaldoxime (IAOx) is a particularly relevant molecule as an intermediate in the pathway for tryptophan-dependent auxin biosynthesis. The role of IAOx in growth-signalling and root phenotype is poorly studied in ... -
Mechanisms of ammonium toxicity and the quest for tolerance
Ammonium sensitivity of plants is a worldwide problem, constraining crop production. Prolonged application of ammonium as the sole nitrogen source may result in physiological and morphological disorders that lead to decreased ... -
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, ... -
Synthesis and Leishmanicidal activity of novel urea, thiourea, and selenourea derivatives of diselenides
A novel series of thirty-one N-substituted urea, thiourea, and selenourea derivatives containing diphenyldiselenide entities were synthesized, fully characterized by spectroscopic and analytical methods, and screened for ...
