• Both foliar and residual applications of herbicides that inhibit amino acid biosynthesis induce alternative respiration and aerobic fermentation in pea roots 

      Armendáriz García, Óscar Upna; Gil Monreal, Miriam Upna; Zulet González, Amaia Upna; Zabalza Aznárez, Ana Upna; Royuela Hernando, Mercedes Upna (Wiley, 2016)   Artículo / Artikulua  OpenAccess
      The objective of this work was to ascertain whether there is a general pattern of carbon allocation and utilisation in plants following herbicide supply, independent of the site of application: sprayed on leaves or supplied ...
    • Branched-chain amino acid biosynthesis inhibitors: herbicide efficacy is associated with an induced carbon–nitrogen imbalance 

      Zabalza Aznárez, Ana Upna; Zulet González, Amaia Upna; Igal Díaz de Cerio, María Upna; Gil Monreal, Miriam Upna; Royuela Hernando, Mercedes Upna (Elsevier, 2013)   Artículo / Artikulua  OpenAccess
      Acetolactate synthase (ALS; EC 4.1.3.18) and ketol-acid reductoisomerase (KARI; EC 1.1.1.86) are two consecutive enzymes in the biosynthesis of branched-chain amino acids. Several commercial herbicides inhibit ALS as their ...
    • 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. ...
    • Estrategias del alumnado de Educación Secundaria para estimar la densidad 

      Napal Fraile, María Upna; Echeverría Morrás, Jesús Upna; Zulet González, Amaia Upna; Santos Cervera, Leyre; Ibarra Murillo, Julia Upna (Universitat Autònoma de BarcelonaUniversitat de València, 2018)   Artículo / Artikulua  OpenAccess
      La densidad, o concentración de materia, es un concepto muy relevante pero que genera muchas dificultades de comprensión. Para medir la competencia en la estimación de la densidad del alumnado de la ESO, se pasó un ...
    • Fermentation and alternative oxidase contribute to the action of amino acid biosynthesis-inhibiting herbicides 

      Zulet González, Amaia Upna; Gil Monreal, Miriam Upna; Zabalza Aznárez, Ana Upna; Dongen, Joost T. van; Royuela Hernando, Mercedes Upna (Elsevier, 2015)   Artículo / Artikulua  OpenAccess
      Acetolactate synthase inhibitors (ALS-inhibitors) and glyphosate (GLP) are two classes of herbicide that act by the specific inhibition of an enzyme in the biosynthetic pathway of branched-chain or aromatic amino acids, ...
    • Impairment of carbon metabolism induced by the herbicide glyphosate 

      Orcaray Echeverría, Luis Upna; Zulet González, Amaia Upna; Zabalza Aznárez, Ana Upna; Royuela Hernando, Mercedes Upna (Elsevier, 2012)   Artículo / Artikulua  OpenAccess
      The herbicide glyphosate reduces plant growth and causes plant death by inhibiting the biosynthesis of aromatic amino acids. The objective of this work was to determine whether glyphosate-treated plants show a carbon ...
    • Phytotoxic and metabolic effects of exogenous quinate on Pisum sativum L. 

      Zulet González, Amaia Upna; Zabalza Aznárez, Ana Upna; Royuela Hernando, Mercedes Upna (Springer US, 2013)   Artículo / Artikulua  OpenAccess
      Quinate (1,3,4,5-tetrahydroxycyclohexanecarboxylate) is a compound synthesized in plants through a side branch of the shikimate biosynthesis pathway. Plants treated with herbicides that inhibit amino acid biosynthesis ...
    • Proteolytic pathways induced by herbicides that inhibit amino acid biosynthesis 

      Zulet González, Amaia Upna; Gil Monreal, Miriam Upna; Villamor, Joji Grace; Zabalza Aznárez, Ana Upna; Hoorn, Renier A.L. van der; Royuela Hernando, Mercedes Upna (Public Library of Science, 2013)   Artículo / Artikulua  OpenAccess
      Background: The herbicides glyphosate (Gly) and imazamox (Imx) inhibit the biosynthesis of aromatic and branched-chain amino acids, respectively. Although these herbicides inhibit different pathways, they have been reported ...
