This research sub-line focuses on the study of plant processes involved in redox signalling and efficient carbon assimilation, as well as on plant tolerance mechanisms to biotic and abiotic stresses. These studies combine physiological, biochemical, biophysical and molecular approaches using plants of agronomic interest such as pea and strawberry, besides other model plants like tobacco and Arabidopsis. The use of molecular, proteomic, crystallographic, immunological and imaging techniques (fluorescence, thermography, etc) allow us to decipher the molecular regulation mechanisms of complex processes in plants including carbon metabolism, key antioxidant systems and the response of the host plant to pathogen infection).
