Hormonal Regulations of Aquaporins and Root Hydraulic Architecture: their Role in Water Deficit Tolerance

The present project aims at understanding mechanisms that determine the root hydraulic architecture, looking at the effects of auxin and ABA on aquaporin function in the lateral root formation, signaling, root architecture and their interactions by a combination of developmental biology, genetics, genomics, biophysics and mathematical modelling. Subsequently, the effects of water deficit will be integrated at the whole root level, by a combination of root phenotyping and quantification of root hydraulic conductivities, which will be incorporated into a mathematical model. Thus, the present work will contribute to an existing functional/structural model of root water transport by integrating novel hormonal and drought stress-dependent regulations.

Biography & research interests

My research experience is focused on the study of physiological, biochemical and molecular responses of higher plants to abiotic stress, with emphasis on drought and heat tolerance and its effects on crop production and quality. I finished my PhD in 2008 at the Department of Plant Physiology (University of Granada, Spain) and, afterwards, I decided to strengthen my skills in plant molecular physiology by carrying out postdoctoral positions in the Biotechnology Institute (UNAM, Mexico, 2008-2010) and the Institute of Natural Resources and Agrobiology (CSIC, Spain, 2011-2012). This allowed me to investigate at the whole plant level several main physiological functions such as antioxidant metabolism, osmotic adjustment and water relations, photosynthesis and assimilation pathways of carbon, nitrogen and other nutrients. Since 2014, thanks to the funding of AgreenSkills and H2020-MSCA-IF-2014 programs, I still work at the BPMP department (INRA/CNRS/ SupAgro/UM Montpellier, France) studying the physiological and molecular interplay between root hydraulics and architecture during drought stress.
