    Antioxidants and cellular redox state in plants of agronomic and ecological interest

  F. Tommasi, C. Paciolla, C. de Pinto

The main goal of this research topic is to study the relationships between the different partners involved in the control of the cellular redox homeostasis to better understand how the different proteins and metabolites are regulated in response of specific steps of plant development. The isolation and characterization of molecular markers using functional, genomic and proteomic approaches will provide the tools required for biotechnological applications in plants. The final goal is the development of strategies aimed at improving productivity, nutritional quality of crops, or improving plant resistance to adverse environmental conditions.
