    • Drought tolerance response of high-yielding soybean varieties to mild drought: physiological and photochemical adjustments 

      Buezo Bravo, Javier Upna; Sanz Sáez, Álvaro; Morán Juez, José Fernando Upna Orcid; Soba Hidalgo, David Upna; Aranjuelo Michelena, Iker Upna Orcid; Esteban Terradillos, Raquel (Wiley, 2019)   Artículo / Artikulua  OpenAccess
      Soybean is a crop of agronomic importance that requires adequate watering during its growth to achieve high production. In this study, we determined physiological, photochemical and metabolic differences in five soybean ...
    • IAOx induces the SUR phenotype and differential signalling from IAA under different types of nitrogen nutrition in Medicago truncatula roots 

      Buezo Bravo, Javier Upna; Esteban Terradillos, Raquel; Cornejo Ibergallartu, Alfonso Upna Orcid; López Gómez, Pedro Upna Orcid; Marino Bilbao, Daniel Upna Orcid; Chamizo Ampudia, Alejandro Upna; Gil Idoate, María José Upna Orcid; Martínez Merino, Víctor Upna Orcid; Morán Juez, José Fernando Upna Orcid (Elsevier, 2019)   Artículo / Artikulua  OpenAccess
      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 ...
    • The importance of the urea cycle and its relationships to polyamine metabolism during ammonium stress in Medicago truncatula 

      Urra Rodríguez, Marina; Buezo Bravo, Javier Upna; Royo Castillejo, Beatriz Upna; Cornejo Ibergallartu, Alfonso Upna Orcid; López Gómez, Pedro Upna Orcid; Cerdán Ruiz, Daniel; Esteban Terradillos, Raquel; Martínez Merino, Víctor Upna Orcid; Gogorcena, Yolanda; Tavladoraki, Paraskevi; Morán Juez, José Fernando Upna Orcid (Oxford University Press, 2022)   Artículo / Artikulua  OpenAccess
      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 ...
    • Indole-3-acetaldoxime delays root iron-deficiency responses and modify auxin homeostasis in medicago truncatula 

      Roman, Angela; Montenegro, Joaquín; Fraile, Laura; Urra Rodríguez, Marina; Buezo Bravo, Javier Upna; Cornejo Ibergallartu, Alfonso Upna Orcid; Morán Juez, José Fernando Upna Orcid; Gogorcena, Yolanda (Elsevier, 2023)   Artículo / Artikulua  OpenAccess
      Iron (Fe) is an essential plant micronutrient, being a major limiting growth factor in calcareous soils. To increase Fe uptake, plants induce lateral roots growth, the expression of a Fe(III)-chelate reductase (FCR), a ...
    • Oximes and nitric oxide signalling in Medicago truncatula root system architecture 

      Buezo Bravo, Javier Upna (2020)   Tesis doctoral / Doktoretza tesia
      El óxido nítrico (NO) es una molécula señalizadora ampliamente conocida en el mundo vegetal, relacionada con cada etapa en el desarrollo de la planta. De entre todas sus funciones descritas, se sabe que actúa sinérgicamente ...
    • The proteome of Medicago truncatula in response to ammonium and urea nutrition reveals the role of membrane proteins and enzymes of root lignification 

      Royo Castillejo, Beatriz Upna; Esteban Terradillos, Raquel; Buezo Bravo, Javier Upna; Santamaría, Enrique; Fernández Irigoyen, Joaquín Upna Orcid; Becker, Dirk; Morán Juez, José Fernando Upna Orcid (Elsevier, 2019)   Artículo / Artikulua  OpenAccess
      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, ...
    • A study of the interface of gold nanoparticles conjugated to cowpea fe-superoxide dismutase 

      Tellechea Malda, Edurne; Asensio, Aarón C.; Ciáurriz Gortari, Paula; Buezo Bravo, Javier Upna; López Gómez, Pedro Upna Orcid; Urra Rodríguez, Marina; Morán Juez, José Fernando Upna Orcid (MDPI, 2022)   Artículo / Artikulua  OpenAccess
      The iron superoxide dismutase (FeSOD) is a first barrier to defend photosynthetic organisms from superoxide radicals. Although it is broadly present in plants and bacteria, FeSODs are absent in animals. They belong to the ...
    • Tryptophan levels as a marker of auxins and nitric oxide signaling 

      López Gómez, Pedro Upna Orcid; Smith, Edward N.; Bota, Pedro; Cornejo Ibergallartu, Alfonso Upna Orcid; Urra Rodríguez, Marina; Buezo Bravo, Javier Upna; Morán Juez, José Fernando Upna Orcid (MDPI, 2022)   Artículo / Artikulua  OpenAccess
      The aromatic amino acid tryptophan is the main precursor for indole-3-acetic acid (IAA), which involves various parallel routes in plants, with indole-3-acetaldoxime (IAOx) being one of the most common intermediates. ...
