Systems Biology of Plant Responses to Stress

Group Leaders
Group Members

Overview

Our group is interested in investigating how plants respond to adverse environments from a systemic perspective. To this end, we conduct high-throughput profiling and systems-wide analysis of transcriptome, proteomes and metabolomes changes in plants exposed to broad ranges of abiotic and biotic stressors in single and combinatorial designs. Our research is mainly based on the model plant Arabidopsis thaliana, but also extend our focus to other plants of agronomical interest, such as tomato, rice, and melon. The main goals of the group are: (i) the reconstruction of networks to provide holistic interpretations and decipher novel components in plant responses to stress; (ii) the identification of evolutionary-driven strategies for plant adaptation to adverse environments, (iii) the combination of Molecular Biology with Bioinformatics to elaborate predictive models that anticipate plant responses to frequent environmental perturbations and (iv) the assistance with experimental designs and data analysis to stablish synergies with other research groups in the field.
