    • Application of anti-transpirants temporarily alleviates the inhibition of symbiotic nitrogen fixation in drought-stressed pea plants 

      Aldasoro Galán, Joseba Upna; Larrainzar Rodríguez, Estíbaliz Upna; Arrese-Igor Sánchez, César Upna (Elsevier, 2019)   Artículo / Artikulua  OpenAccess
      Stomatal closure is one of the first plant responses under a water deficit situation. This leads to a decline in transpiration but also in the plant photosynthetic activity. Legume plants grown under symbiosis with rhizobium ...
    • Drought stress causes a reduction in the biosynthesis of ascorbic acid in soybean plants 

      Seminario Huárriz, Amaia Upna; Song, Li; Zulet González, Amaia Upna; Nguyen, Henry T.; González García, Esther Upna; Larrainzar Rodríguez, Estíbaliz Upna (Frontiers Media, 2017)   Artículo / Artikulua  OpenAccess
      Drought provokes a number of physiological changes in plants including oxidative damage. Ascorbic acid (AsA), also known as vitamin C, is one of the most abundant water-soluble antioxidant compound present in plant tissues. ...
    • 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 ...
    • Drought stress responses in Medicago truncatula and Glycine max: system biology approaches 

      Seminario Huárriz, Amaia Upna (2017)   Tesis doctoral / Doktoretza tesia  OpenAccess
      After cereals, legumes are crops of great economic importance. However, legume plants are very sensitive to abiotic stresses, being drought one of the most harmful stress in terms of crop production. The general aim of ...
    • ¿Están los bosques mixtos pirenaicos de pino silvestre y haya en el camino hacia la saturación por nitrógeno? 

      Blanco Vaca, Juan Antonio Upna; San Emeterio Garciandía, Leticia Upna; González de Andrés, Ester Upna; Imbert Rodríguez, Bosco Upna; Larrainzar Rodríguez, Estíbaliz Upna; Peralta de Andrés, Francisco Javier Upna; Lo, Yueh-Hsin Upna; Castillo Martínez, Federico Upna (Asociación Española de Ecología Terrestre, 2017)   Artículo / Artikulua  OpenAccess
      Las actividades humanas causan altos niveles de deposición atmosférica crónica de N que pueden estar trastornando el ciclo del N en los bosques de los Pirineos occidentales. Para probar esta hipótesis, se han investigado ...
    • 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 ...
    • 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 ...
    • A proteomic view on the role of legume symbiotic interactions 

      Larrainzar Rodríguez, Estíbaliz Upna; Wienkoop, Stefanie (Frontiers Media, 2017)   Artículo / Artikulua  OpenAccess
      Legume plants are key elements in sustainable agriculture and represent a significant source of plant-based protein for humans and animal feed worldwide. One specific feature of the family is the ability to establish ...
