Plant-Fungus Interactions and Remediation Team (IPCR)

Research activity

The IPCR team’s research activities are based on its expertise in mycology, in particular on the interactions between plants and fungi (phytopathogenic as well as symbiotic fungi), and in physiology, cytology, biochemistry, molecular biology and microbial ecology. They are organized in two main fields :

1 – Biocontrol of wheat foliar fungal diseases

This research theme aims to develop new biocontrol and sustainable control strategies against wheat fungal parasites, using Plant Defense Stimulants (PDSs) and/or beneficial bacterial (Plant Growth-Promoting Rhizobacteria) or fungal (Plant Growth-Promoting Fungi) microorganisms such as arbuscular mycorrhizal fungi and/or biostimulants in plant protection. Our studies focus on two pathosystems in particular, wheat/Blumeria graminis f.sp. tritici (agent of powdery mildew) and wheat/Zymoseptoria tritici (agent of septoria). The study of defense reactions in wheat and the optimization of the protective efficacy of SDPs in response to various environmental factors that may influence the establishment of such protection (wheat genotype, nutritional status of the plant, soil microbiota, climate change, etc.) are the main objectives of our work.

2- Phytomanagement and Bioremediation of contaminated soils.

This research theme aims to develop alternative, gentle and sustainable methods of remediation and management of contaminated soils.

In the case of phytomanagement, the feasibility, effectiveness and sustainability of the main phytotechnologies (phytostabilisation, phyto/rhizodegradation and phytoextraction) are being studied from the laboratory scale under controlled conditions to that of in situ workshop sites (demonstrators).
The aim is (1) to study the performance of different plant species and soil improvers, especially biological ones based on arbuscular mycorrhizal fungi, in the fate (mobility, transfer, dissipation) of organic pollutants (e.g., in the form of a fungus): PAHs, dioxins/furans, alkanes) and inorganic pollutants (trace elements), (2) to develop non-food channels for the valorisation of phytomass produced on polluted soils, (3) to monitor the influence of phytotechnologies on the refunctioning of contaminated soils, in particular via the characterisation of their microbiota and (4) to assess the environmental and health risks after treatment.

In a complementary way, bioremediation consists in exploiting, in particular, the diversity of saprotrophic fungi within the framework of the biodegradation of organic pollutants such as PAHs, dioxins/furans and emerging pollutants not only in the soil but also in other matrices (water, sediments, gaseous effluents, biogas). This work aims to study the mechanisms involved in the degradation of organic pollutants (availability, transport and incorporation, degradation), and the interest of using natural polysaccharides (modified starches) as solubilising agents for these pollutants.
