Signalling Oxigen Species and Reactive Nitrogen Situations Stress in Plants

General Objectives

Address from a multidisciplinary perspective, using techniques of biochemistry, cell and molecular biology, the study of the mechanisms involved in plant response to different types of stress in order to apply the knowledge gained in the design of plant breeding strategies. The Group's research focuses on two fundamental: 1) The study of the role of oxygen species and reactive nitrogen species (ROS and RNS) as signal molecules in the regulation of gene expression and enzyme activity (using NO-dependent posttranslational modifications) in response to heavy metals and xenobiotic infection by pathogens. Additionally, we studied the interaction between different cellular sources of ROS and RNS in regulating the cellular response to stress. An important objective is to establish the role of peroxisome dynamics in regulating the cellular response to stress and possible interactions with other cellular organelles. 2) Phytoremediation design strategies based on the selection and characterization of Arabidopsis mutants resistant to heavy metals and their subsequent use by using biotechnological species of agronomic interest, for the recovery and conservation of soils contaminated with metals.
