    • Depletion of the heaviest stable N isotope is associated with NH4+/NH3 toxicity in NH4+-fed plants 

      Ariz, Idoia Upna Orcid; Cruz, Cristina; Morán Juez, José Fernando Upna Orcid; González Moro, María Begoña; García Olaverri, Carmen Upna Orcid; González Murua, Carmen; Martins Loucao, María A.; Aparicio Tejo, Pedro María Upna Orcid (BioMed Central, 2011)   Artículo / Artikulua  OpenAccess
      Background: In plants, nitrate (NO3-) nutrition gives rise to a natural N isotopic signature (δ15N), which correlates with the δ15N of the N source. However, little is known about the relationship between the δ15N of the ...
    • Effect of feeding regime on composting in bins 

      Storino, Francesco Upna Orcid; Menéndez Villanueva, Sergio Upna Orcid; Muro Erreguerena, Julio Upna Orcid; Aparicio Tejo, Pedro María Upna Orcid; Irigoyen Iriarte, Ignacio Upna Orcid (Taylor & Francis, 2017)   Artículo / Artikulua  OpenAccess
      Composting in bins is one of the most practical home composting methods. There is currently a need for greater information to improve the management of the composting process and to create home composting programs, which ...
    • Elevated CO2 improved the growth of a double nitrate reductase defective mutant of Arabidopsis thaliana: the importance of maintaining a high energy status 

      Jáuregui Mosquera, Iván Upna Orcid; Aparicio Tejo, Pedro María Upna Orcid; Baroja Fernández, Edurne Upna Orcid; Ávila, Concepción; Aranjuelo Michelena, Iker Upna Orcid (Elsevier, 2017)   Artículo / Artikulua  OpenAccess
      Impairments in leaf nitrogen (N) assimilation in C3 plants have been identified as processes conditioning photosynthesis under elevated [CO2], especially when N is supplied as nitrate. Leaf N status is usually improved ...
    • Improving the short‑term efficiency of rock phosphate‑based fertilizers in pastures by using edaphic biostimulants 

      Fernández, L.; Baigorri, R.; Urrutia Vera, Olaia Upna Orcid; Erro, J.; Aparicio Tejo, Pedro María Upna Orcid; Yvin, J. C.; García Mina, José M. (Springer, 2016)   Artículo / Artikulua  OpenAccess
      Background: The use of reactive rock phosphate (RP) in acidic soils as a phosphate (P) source for pastures and crops presents attractive economic advantages with respect to soluble phosphate. However, some studies have ...
    • Isotopic composition of maize as related to N-fertilization and irrigation in the Mediterranean region 

      Lasa Larrea, Berta Upna Orcid; Irañeta, Iosu; Muro Erreguerena, Julio Upna Orcid; Irigoyen Iriarte, Ignacio Upna Orcid; Aparicio Tejo, Pedro María Upna Orcid (Escola Superior de Agricultura "Luiz de Queiroz", Universidade de São Paulo, 2011)   Artículo / Artikulua  OpenAccess
      Nitrate leaching as a result of excessive application of N-fertilizers and water use is a major problem of vulnerable regions. The farming of maize requires high N fertilization and water inputs in Spain. Isotopic ...
    • Leaf δ15N as a physiological indicator of the responsiveness of N2-fixing alfalfa plants to elevated CO2, temperature and low water availability 

      Ariz, Idoia Upna Orcid; Cruz, Cristina; Neves, Tomé; Irigoyen, Juan J.; García Olaverri, Carmen Upna Orcid; Nogués, Salvador; Aparicio Tejo, Pedro María Upna Orcid; Aranjuelo Michelena, Iker Upna Orcid (Frontiers Media, 2015)   Artículo / Artikulua  OpenAccess
      The natural 15N/14N isotope composition (δ15N) of a tissue is a consequence of its N source and N physiological mechanisms in response to the environment. It could potentially be used as a tracer of N metabolism in plants ...
    • Pea plant responsiveness under elevated [CO2] is conditioned by the N source (N2 fixation versus NO3 fertilization) 

      Aranjuelo Michelena, Iker; Cabrerizo, Pablo María Upna; Arrese-Igor Sánchez, César Upna Orcid; Aparicio Tejo, Pedro María Upna Orcid (Elsevier, 2013)   Artículo / Artikulua  OpenAccess
      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 ...
    • Unraveling the role of transient starch in the response of Arabidopsis to elevated CO2 under long-day conditions 

      Jáuregui Mosquera, Iván Upna Orcid; Pozueta Romero, Javier Upna Orcid; Aparicio Tejo, Pedro María Upna Orcid; Baroja Fernández, Edurne Upna Orcid; Aranjuelo Michelena, Iker Upna Orcid (Elsevier, 2018)   Artículo / Artikulua  OpenAccess
      Previous studies on Arabidopsis under long-term exposure to elevated CO2 have been conducted using starch synthesis and breakdown mutants cultured under short day conditions. These studies showed that starch synthesis can ...
    • Unravelling the mechanisms that improve photosynthetic performance of N₂-fixing pea plants exposed to elevated [CO₂] 

      Aranjuelo Michelena, Iker Upna Orcid; Cabrerizo, Pablo María Upna; Aparicio Tejo, Pedro María Upna Orcid; Arrese-Igor Sánchez, César Upna Orcid (Elsevier, 2014)   Artículo / Artikulua  OpenAccess
      Although the predicted enhanced photosynthetic rates of plants exposed to elevated [CO₂] are expected to increase carbohydrate and plant growth, recent findings have shown a complex regulation of these processes. The aim ...
    • Yield and quality of sugar snap pea in the Ebro Valley: sowing date and seed density 

      Azpilicueta Unanua, Miren Upna; Irigoyen Iriarte, Ignacio Upna Orcid; Lasa Larrea, Berta Upna Orcid; Muro Erreguerena, Julio Upna Orcid; Aparicio Tejo, Pedro María Upna Orcid (Escola Superior de Agricultura "Luiz de Queiroz", Universidade de São Paulo, 2012)   Artículo / Artikulua  OpenAccess
      Sugar snap pea (Pisum sativum L. var. macrocarpon Ser.) is an edible-podded sweet pea that is being considered as a new totally mechanized crop to supply raw material to the agri-food industry of the Ebro Valley (Northern ...
