Education/Training

Studies of Biology. 2001. University of Granada, Spain.

Pre-graduate fellowship. 2000/2001. Biochemistry Department, University of Granada, Spain.

Diploma (MSc). 2005. Biología Agraria y Acuicultura. University of Granada, Spain.

PhD Thesis. 2007. University of Granada, Spain. Supervised by Dra. Carmen Lluch Plá. Title: Nodular carbon metabolism in the symbiosis Medicago truncatula-Sinorhizobium meliloti, Lotus japonicus-Mesorhizobium loti under salt stress: role of trehalose.

Predoctoral research
My research trajectory has been focused in the symbiotic interaction between legumes and soil bacteria known as rhizobia. In this interaction, the bacteria reduce atmospheric nitrogen to ammonia which is supplied to the plant that provide the appropriate conditions allowing this process to takes place. My Master Thesis and PhD Thesis projects consisted in the study of the adaptation to salt stress conditions of the nitrogen fixation process. Those studies were approached from two different perspectives:

a) the effects of salinity on the cellular osmotic potential by determining the biochemical and physiological mechanisms involved in salt adaptation such as accumulation of compatible osmolytes, b) the nutrient balance by the analysis of the effect of high salinity in the nutrient distribution in the plant. The negative effect of salt stress was also determined in other plant major processes such as cell respiration, photosynthetic activity and nitrogen and carbon metabolism.

Postdoctoral research
During my postdoctoral research period I worked in a two years project funded by the Spanish Education Ministry and the Swiss National Foundation in the Botanical Institute of the University of Basel (Switzerland). The aim of this project was to determine the capacity of legumes to discriminate between symbiotic and pathogenic microorganisms, for this purpose I studied the immune responses in roots of legumes upon treatment with different elicitors, and how do they affect the establishment of nitrogen fixation symbiosis in order to determine a possible cross-talk between the signalling pathways involved in the symbiosis and innate immunity. The aim of my current research activity is to study the involvement of plant growth regulators such as polyamines and brassinosteroids in root nodule organogenesis and functioning under stress conditions in order to generate new tools to improve the tolerance to salt stress conditions of legume crops.

Research Areas:

  • Rhizobium-legume symbiosis
  • Biological nitrogen fixation
  • Salinity stress
  • Plant growth regulation

Current N-related Projects:

  • Rhizobium-legume symbiosis: biological nitrogen fixation
  • Nodule carbon and nitrogen metabolism.
  • Markers of oxidative stress in response to salinity in the rhizobium-legume symbiosis.
  • Symbiosis versus pathogenesis during the initial stages of the symbiosis establishment.
  • Use of the Rhizobium-legume symbiosis for the recovery of degraded or contaminated soils.
