Mobility project

Molecular analysis of phloem tissue and its interaction with phytoplasmas. Investigations on sugars transporters and genes involved in carbon allocation.

Phloem is the plant vascular tissue used to translocate photoassimilates. This tissue consists in highly specialized cells that permit the transport of sugars and other molecules from leaves to sink organs. The transport of sugars is a complex mechanism and several different proteins are involved. Phloem functions can be altered by plant pathogens as phytoplasmas and abiotic stresses. The project will focus on the comprehension of transport mechanisms and the impairment of phloem function and carbon allocation under stress conditions.

Biography & research interests

Federica De Marco has graduated in Agricultural Biotechnology at the University of Udine (Italy) in 2009. She has obtained her PhD from the doctoral course “Agriculture Science and Biotechnology” at the University of Udine (2011-2013).

The title of the PhD thesis was “Stolbur phytoplasma and its interactions with the phloem tissue”. Her research interests relate to the interactions between pathogen and plant host. Phytoplasma infection severely affects the quantity and quality of several crop species. The comprehension of molecular mechanisms involved in the disease process caused by phytoplasmas was the topic of the PhD project. Studies were conducted integrating microscopy and molecular biology techniques.

After the PhD, she attended a two-year post doc project funded by AgreenSkills at IJPB Institute at INRA - Versailles (2014- 2016). Currently she is still working at IJPB with a SPS’innov funding project of one year in collaboration with Groupe Roullier, French enterprise leader in fertilizers and biostimulant/ biocontrol products.
