Biography:

I got my M.Sc. Biology (1981) and Ph.D. Biology (1985) at the University of Navarra (Spain) with National Prize for the best academic record and  Special Award, respectively. In 1986 I earned a permanent position as Assistant Professor at CSIC-Salamanca and then I did postdoctoral work at the University of Dundee (UK) and University of Nebraska-Lincoln (USA) under the supervision of Prof. Janet Sprent and Prof. Robert Klucas, respectively. In 1992 I was promoted to Associate Professor and in 2001 to Full Professor. Since 1992 I am a group leader at Zaragoza-CSIC. During my whole scientific career, including my PhD, I have been working in various aspects related to nitrogen fixation by the rhizobia-legume symbiosis, initially with crop legumes (alfalfa, pea, common bean, soybean) and afterwards with both model legumes (mainly Lotus japonicus) and crops. My main interests are in the areas of reactive oxygen/nitrogen species (especially hydrogen peroxide and nitric oxide), antioxidants, oxidative/nitrosative stress in nodules, redox regulation, leghemoglobins, and nonsymbiotic hemoglobins.

Research Areas:

  • Antioxidants
  • Oxidative and nitrosative signaling and stress
  • Plant symbiotic and nonsymbiotic hemoglobins
  • Reactive oxygen and nitrogen species
  • Redox regulation in nodules
  • Symbiotic nitrogen fixation

Current N-related Projects:

  • Symbiotic nitrogen fixation: antioxidants, abiotic stress and senescence in nodules of model and crop legumes

    Spanish Programme of Agriculture grant no. AGL2008-01298

    2009-2011

  • Signaling by reactive oxygen/nitrogen species and antioxidants in the nitrogen-fixing rhizobia-legume symbiosis

    Spanish Programme of Agriculture grant no. AGL2011-24524

    2012-2014

  • Structure and function of legume hemoglobins

    Special CSIC grant no. 201240E150

    2013-2015

  • Nitrogen fixation by the rhizobium-legume symbiosis: hemoglobins and protein oxidative modifications during nodule development and senescence

    Spanish Programme of Agriculture grant no. AGL2014-53717-R

    2015-2017 

  • Function of hemoglobins and nitric oxide in the rhizobium-legume symbiosis

    Spanish Programme of Agriculture grant no. AGL2017-85775-R
