Research project

Analysis of Tyrosyl-DNA phosphodiesterase isoforms Tdp1α and Tdp1β and role of chromatin remodeling in plants
My research program will be focused on the molecular aspects of the genotoxic stress response in plant cells, the subject currently approached at the laboratory of Plant Biotechnology in the Department of Biology and Biotechnology of the University of Pavia, through new and integrated approaches. Plant organisms are subjected to several environmental abiotic and biotic stresses that determine the accumulation of Reactive Oxygen species (ROS) associated to deleterious effects on the genome stability. Oxidative stress fatally compromises the farm productivity and it’s necessary to define new and effective strategy with the purpose to increase the tolerance to the environmental stresses in the crop fields. New information will be acquired about the role in planta of the Tyrosyl-DNA phosphodiesterase enzymes involved in the NER and BER mechanisms, responsible of DNA repair in different DNA lesions. Functional analysis of the promoters of the genes Mt Tdp1α and Mt Tdp1β, previously isolated and characterized, will be performed through the production of transgenic lines expressing reporter gene construct. Will be so possible verify the spatio-temporal activity of the promoters and explore the possibility for biotechnological applications. In the same time a bioinformatic investigation utilizing data from RNA-seq analysis of Medicago truncatula transgenic lines silenced for the Tdp1α gene will be performed. Considering the relevant role played by the DNA repair processes, the investigation area will be extended to new model systems (ornamental species) and to new problems associated to the damage caused by ionizing radiations.
