Activités de


My research activities revolve around three main axes. For each of these activities, we use i) classical microbiology (isolation, culture, morphological identification), ii) molecular biology from the strain (characterization, identification) to the microbial community (taxonomic and functional diversity via omics), iii) pathology (greenhouse and field bioassays).
The first axis concerns the ecology of Fusarium, in particular F. oxysporum. We are looking for specific markers of forma speciales to offer preventive risk diagnoses in horticulture and market gardening production systems. We also dissect the mechanisms of soil suppressiveness to Fusarium wilt to establish the possibilities of transition from a conducive soil to a suppressive soil.
The second axis aims at reducing the pea and lentil root rot. In addition to the search for a molecular kit for a preventive diagnosis of the risk linked to the presence of Aphanomyces euteiches in the plots, we characterize the parasitic complex also involved in legume root rot and in which the genus Fusarium plays a major role, to reduce its activity by agroecological levers.
The third axis proposes to identify mycoherbicides and their modes of action for weed and parasitic plants. Biocontrol.
