The fourth set of objectives is a new, wide theme that our team aims to develop over the next five years. The starting point is the INRAE collective expertise “RegulNat” and associated multidisciplinary projects, whose conclusions - such as the benefits of crop diversification for plant health - are challenged by overlooked phytopathological realities, including detrimental effects. Thus, we focus our attention on this somewhat neglected issue by characterizing the impact of interactions between cultivated and wild compartments on wheat pathogen populations (service and disservice plants; alternate and alternative hosts).

Key areas of investigation include:

4.1. Understand the impact of interactions between cultivated and wild plants on diseases (re)emergence. This work, using the Puccinia graminis f. sp. tritici-wheat pathosystem as a case study, began in 2023 with the FSOV RouilleNoire_2.0 project in collaboration with colleagues from the Aarhus University (Denmark) and HAFL (Switzerland), and in 2024 with the Alicia Culot's PhD project in collaboration with Samuel Soubeyrand (INRAE BioSP).

4.2. Formalize epidemiological knowledge to analyze and manage risk in plant health. We are participating in the development of a European project focused on preparedness against agricultural, feed, and food bioterrorism. This perspective resonates with previous works for which some members of the team are identified, emphasizing the significance of risk assessment and management for expertise applied to new public policies (ANSES, CTPS, etc.) under uncertain geopolitical contexts.
