    My research career has focused on molecular mechanism controlling plant stress responses leading to plant stress tolerance. Plant stress responses are controlled by the fine tuning interaction of plant hormones as abscisic acid (ABA) or jasmonic acid derivates (JAs). Indeed, ABA steers a multitude of plant adaptive responses that enhances plant survival and productivity under stress conditions and is a pivotal target for plant biotechnology.

    During my PhD, I identified new mutant alleles of ABA biosynthesis ABA1, ABA2 and AAO3 genes as key players of plant abiotic stress response. We showed that ABA functions not only in plant stress responses but also in plant growth of non-stressed plants.

    During my postdoctoral in Gent, I was focused on JA-dependent reprogramming of plant secondary metabolism in plant biotic stress conditions. We identified an ERAD -type RING membrane-anchor E3 ubiquitin ligase controlling the activity of 3-hydroxy-3-methylglutaryl-CoA reductase (HMGR), showing that JAs phytohormone recruits the ERAD quality control system to manage the production of plant defence metabolite synthesis.

    As postdoctoral of the ABA signalling group of Dr. Pedro Rodriguez, I have been involved in the characterization of core ABA signalling elements as well in the identification of new components of the ABA signalling pathway using Arabidopsis and tomato plants. As a result, I have established the predominant role in planta of PYR/PYL/RCAR ABA receptors in ABA signalling against others ABA receptors identified. Moreover, I have found new ABA signalling players including two regulatory proteins of the ABA PYR/PYL/RCAR receptors involved in ABA signalling membrane-delimited events.

    In collaboration with several Europeans groups, I have found hormonal crosstalk between ABA signalling and others signalling pathways. Of relevant interest is the crosstalk between biotic and abiotic plant stress responses I found since many times crops have to survive to a combination of both stresses. Understanding the molecular mechanism of this hormonal crosstalk has a high biotechnological potential. To increase my knowledge of stress combination I stayed from 2015 to 2018 at Plant-Insect Interaction group headed by Prof. Pedro Castañera and Dr. Felix Ortego where I obtained a Young Investigator (JIN) project from the Spanish Government to develop a research line to understand hormonal signalling mechanisms steering plant stress tolerance under stress combination.

    In 2017, I obtained a Ramon y Cajal research contract which allow me to join the Ecofisiología y Biotecnología headed by the professor Aurelio Gomez Cadenas where I am continuing my research line “Hormonal signalling mechanisms steering plant stress tolerance under stress combination”.
