• Disponibilidad hídrica y fijación de nitrógeno en leguminosas: fisiología, metabolismo y proteómica 

      Aldasoro Galán, Joseba Upna (2017)   Tesis doctoral / Doktoretza tesia  OpenAccess
      Las entradas de nitrógeno al suelo por medio de la fijación biológica llevada a cabo por plantas de la familia de las leguminosas en simbiosis con bacterias del suelo (rizobios), disminuyen la necesidad de aporte externo ...
    • Drought stress provokes the down-regulation of methionine and ethylene biosynthesis pathways in Medicago truncatula roots and nodules 

      Larrainzar Rodríguez, Estíbaliz Upna; Molenaar, Johanna A.; Wienkoop, Stefanie; Gil Quintana, Erena Upna; Alibert, Bénédicte; Limami, Anis M.; Arrese-Igor Sánchez, César Upna; González García, Esther Upna (Wiley, 2014)   Artículo / Artikulua  OpenAccess
      Symbiotic nitrogen fixation is one of the first physiological processes inhibited in legume plants under water-deficit conditions. Despite the progress made in the last decades, the molecular mechanisms behind this ...
    • Is N-feedback involved in the inhibition of nitrogen fixation in drought-stressed Medicago truncatula? 

      Gil Quintana, Erena Upna; Larrainzar Rodríguez, Estíbaliz Upna; Arrese-Igor Sánchez, César Upna; González García, Esther Upna (Oxford University PressSociety for Experimental Biology, 2013)   Artículo / Artikulua  OpenAccess
      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 

      Gil Quintana, Erena Upna; Larrainzar Rodríguez, Estíbaliz Upna; Seminario Huárriz, Amaia Upna; Díaz Leal, Juan Luis; Alamillo, Josefa M.; Pineda, Manuel; Arrese-Igor Sánchez, César Upna; Wienkoop, Stefanie; González García, Esther Upna (Oxford University PressSociety for Experimental Biology, 2013)   Artículo / Artikulua  OpenAccess
      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 

      Sassi, Sameh; Aydi, Samir; Hessini, Kamel; González García, Esther Upna; Arrese-Igor Sánchez, César Upna; Abdelly, Chedly (Academic Journals, 2010)   Artículo / Artikulua  OpenAccess
      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 ...
    • Metabolismo del azufre en la simbiosis guisante - rhizobium 

      Muñoz Azcárate, Olaya Upna (2014)   Tesis doctoral / Doktoretza tesia  OpenAccess
      Las leguminosas constituyen un cultivo importante para la agricultura sostenible, debido en parte a su capacidad para fijar el N atmosférico en simbiosis con bacterias del suelo mediante la fijación biológica de nitrógeno ...
    • Nodule carbohydrate catabolism is enhanced in the Medicago truncatula A17-Sinorhizobium medicae WSM419 symbiosis 

      Larrainzar Rodríguez, Estíbaliz Upna; Gil Quintana, Erena Upna; Seminario Huárriz, Amaia Upna; Arrese-Igor Sánchez, César Upna; González García, Esther Upna (Frontiers Media, 2014)   Artículo / Artikulua  OpenAccess
      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 ...
    • Physiological responses of legume nodules to drought 

      Arrese-Igor Sánchez, César Upna; González García, Esther Upna; Marino Bilbao, Daniel Upna; Ladrera Fernández, Rubén Upna; Larrainzar Rodríguez, Estíbaliz Upna; Gil Quintana, Erena Upna (Global Science Books, 2011)   Artículo / Artikulua  OpenAccess
      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 ...
