BIOGER (Biology and management of risks in agriculture)

UMR 1290 AgroParisTech, INRAE, Université Paris-Saclay

General scientific background

The BIOGER (fungal Biology and Risk Management in Agriculture) INRAE-AgroParisTech joint research unit is the French reference centre for research on fungal diseases of major crops in Europe (wheat, rapeseed and grapevine). BIOGER undertakes pluridisciplinary and multiscale approaches (genomics, molecular biology and biochemistry, cell biology, genetics, population genetics, evolution, epidemiology, modelling, phenotyping, diagnosis and taxonomy ; from gene to landscape).

BIOGER is a strong cross-disciplinary research unit devoted to “field to gene” research on main fungal phytopathogens of crops of primary importance for French agriculture in order to reach sustainable management strategies to control these devastating diseases. Our main models comprise wheat rusts, Zymoseptoria tritici of wheat (Septoria Leaf Blotch-STB), Leptosphaeria maculans (stem canker) of oilseed rape, generalist pathogens as Botrytis cinerea and Colletotrichum species causing grey mould disease or anthracnose, respectively, on a series of hosts. Except for L. maculans, all these fungi are ranked among the world’s ‘Top 10’ fungal pathogens based on their scientific and economic importance, B. cinerea being ranked 2nd and rusts 3rd. The research conducted at BIOGER together with our collaborators has led to these fungal species being raised to the level of models for certain of their genomic, biological, ecological or adaptive traits.

Our work is organized into three major integrated research themes :
1. Deciphering mechanisms involved in biotic interactions within the context of the diseased plant ecosystem
2. Understanding mechanisms and dynamics of adaptation in phytopathogenic fungi
3. Development, evaluation and transfer of sustainable strategies for the management of fungal diseases

Our research generates both basic and operational knowledge, enabling us to address the demands of society and of various agricultural sectors concerning the effective and sustainable management of fungal diseases of field crops.

Fields of research

The unit consists of five teams :
Epidemiology team (airborne diseases of wheat)
♦ Multi-scale host-pathogen adaptation : host specialization and response to qualitative and quantitative resistances
♦ Adaptive responses of plant pathogens to their abiotic environment : from individual to population scale
♦ Epidemic processes focused on the inoculum : impact of interepidemic period on adaptive dynamics of pathogen populations
♦ Sustainable management of varietal resistances : from the identification of agroecological solutions to the assessment of multi-scale deployment strategies

Antifungal agents, mode of action and resistance team (AMAR)
♦ Which are the adaptive processes underlying pathogen adaptation ? (individual & population scales)
♦ How to improve fungicide sustainability in the context of agroecology ? (landscape& agrosystem scales)
♦ How to implement resistance management ? (agricultural sector scale)

Effectors of Fungal-Plant Communication (ECCP)
♦ Which secondary metabolites are produced during infection ? What are their functions and targets ?
♦ Functional analysis of secreted protein effectors targeting plant microtubules
♦ Trans-kingdom communication between fungal pathogens and their plant hosts : Extracellular vesicles, Fungal small interfering RNA, host signals

Evolution and genomics of plant/pathogen interactions team (EGIP)
♦ Adaptive evolution of virulence against resistant genes
♦ Identification of fungal regulatory networks involved in infection
♦ Adaptation to changing environment

Effectors of pathogenesis in Leptosphaeria maculans team (EPLM)
♦ Understanding mechanisms underlying biotic interactions within the plant/pathogen ecosystem
♦ Understanding adaptation and its spatio-temporal dynamics
♦ Identification and evaluation of sustainable disease control methods
